increased levels of aggression and reduced levels of affiliation after fur-rubbing bouts. This observed decrease in group cohesion may be attributable to increased intragroup competition for fur-rub material rather than being a direct effect of fur rubbing itself. To test this hypothesis, we separated individual tufted monkeys (Cebus apella) from their social group and provided them with fur-rub material or control material, thereby avoiding intragroup competition. After engagement with materials, we released subjects back into their social group and observed their subsequent interactions with group members. We found that subjects were more likely to encounter aggression and less likely to receive affiliation from others in the fur-rub condition than in the control condition. These results support the idea that fur rubbing carries social after-effects for capuchin monkeys. The precise mechanisms of the observed effects remain to be clarified in future studies.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Primates","grobid_abstract_attachment_id":32697909},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628217/Social_after_effects_of_fur_rubbing_in_tufted_capuchin_monkeys_Cebus_apella_increased_antagonism_and_reduced_affiliation","translated_internal_url":"","created_at":"2014-01-06T22:29:23.223-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697909,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697909/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697909/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Social_after_effects_of_fur_rubbing_in_t.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697909/fulltext-libre.pdf?1391099032=\u0026response-content-disposition=attachment%3B+filename%3DSocial_after_effects_of_fur_rubbing_in_t.pdf\u0026Expires=1733257089\u0026Signature=FXn7jgpn6vxaC~pb7RpnDpSl3SwywuCsaRZrn2JUN5NuQC2T7trrTmuoYVULPUF4rLsQhSz01reH3r-q6S~-VW6o4xLXOgrUos7AwL6pU00CqKF-i5sibhUuW3fFIr7BavT9kdQxAmbGV4Av1dIJj1OK6FEejtS-SO-M08N1rkpDCDB4JQjnReI8myOOMk5bJtkQg2wBE3UIMdxWMB3fuC726OMEkDtTmoreC1Mk1eNfsMC8lodKbKBW1W9pT25chwjnJursCkOTNGVvyMaHtVJSPAE1xQbODBQAt0vyhOQVjV30atpUsBot0QZk9PzRlfrwszanLgjtNl6NEpv86w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Social_after_effects_of_fur_rubbing_in_tufted_capuchin_monkeys_Cebus_apella_increased_antagonism_and_reduced_affiliation","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697909,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697909/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697909/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Social_after_effects_of_fur_rubbing_in_t.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697909/fulltext-libre.pdf?1391099032=\u0026response-content-disposition=attachment%3B+filename%3DSocial_after_effects_of_fur_rubbing_in_t.pdf\u0026Expires=1733257089\u0026Signature=FXn7jgpn6vxaC~pb7RpnDpSl3SwywuCsaRZrn2JUN5NuQC2T7trrTmuoYVULPUF4rLsQhSz01reH3r-q6S~-VW6o4xLXOgrUos7AwL6pU00CqKF-i5sibhUuW3fFIr7BavT9kdQxAmbGV4Av1dIJj1OK6FEejtS-SO-M08N1rkpDCDB4JQjnReI8myOOMk5bJtkQg2wBE3UIMdxWMB3fuC726OMEkDtTmoreC1Mk1eNfsMC8lodKbKBW1W9pT25chwjnJursCkOTNGVvyMaHtVJSPAE1xQbODBQAt0vyhOQVjV30atpUsBot0QZk9PzRlfrwszanLgjtNl6NEpv86w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

Recent studies have suggested that rather than being a simple reflexive-like behavior, infants exert active control over imitative responses and 'provoke' previously imitated gestures even after a delay of up to 24 h. Delayed imitation is regarded as the hallmark of a sophisticated capacity to control and flexibly engage in affective communication and has been described as an indicator of innate protoconversational readiness. However, we are not the only primates to exhibit neonatal imitation, and delayed imitation abilities may not be uniquely human. Here we report that 1-week-old infant rhesus macaques (Macaca mulatta) who show immediate imitation of a lipsmacking gesture also show delayed imitation of lipsmacking, facilitated by a tendency to refrain from lipsmacking toward a still face during baseline measurements. Individual differences in delayed imitation suggest that differentially matured cortical mechanisms may be involved, allowing some newborns macaques to actively participate in communicative exchanges from birth. Macaque infants are endowed with basic social competencies of intersubjective communication that indicate cognitive and emotional commonality between humans and macaques, which may have evolved to nurture an affective mother-infant relationship in primates.","publication_date":{"day":null,"month":null,"year":2011,"errors":{}},"publication_name":"PLoS ONE","grobid_abstract_attachment_id":32697901},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628212/Delayed_Imitation_of_Lipsmacking_Gestures_by_Infant_Rhesus_Macaques_Macaca_mulatta_","translated_internal_url":"","created_at":"2014-01-06T22:28:29.508-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697901,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697901/thumbnails/1.jpg","file_name":"journal.pone.0028848_1_.pdf","download_url":"https://www.academia.edu/attachments/32697901/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Delayed_Imitation_of_Lipsmacking_Gesture.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697901/journal.pone.0028848_1_.pdf?1389076063=\u0026response-content-disposition=attachment%3B+filename%3DDelayed_Imitation_of_Lipsmacking_Gesture.pdf\u0026Expires=1733257089\u0026Signature=Q4J~jSJlp60GaokrNgOBn6IGjj1QHDn2oKxDq8t3ukSAJbEfrYtvf12wcXSy1y6Xet7VzZR3iRQIdW~TR3oauG8lx-l1Q0fCwF4A3Sjz8fAJ7SwM1ntoJ8hTMJExQ-4NGuvBypHhaLzuw6fujoqKCb73OwZ9wHYgRG6rUDG1pwF235faxMFT4giUZWqkTCWe6a5zArWNz~4UnftUeqYcq9vmXYzqHQCun8GUDYemGmhhpT6ufRM1SZZ5gqISPHtB2zrzJ~d1x-gYCKWP22ai4ziJ14ZmP1-VLklvqYKgNh90uUPVXnGbn-6ysiC9Pun9wzhIovdVY5ksigmLPJI6gQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Delayed_Imitation_of_Lipsmacking_Gestures_by_Infant_Rhesus_Macaques_Macaca_mulatta_","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697901,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697901/thumbnails/1.jpg","file_name":"journal.pone.0028848_1_.pdf","download_url":"https://www.academia.edu/attachments/32697901/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Delayed_Imitation_of_Lipsmacking_Gesture.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697901/journal.pone.0028848_1_.pdf?1389076063=\u0026response-content-disposition=attachment%3B+filename%3DDelayed_Imitation_of_Lipsmacking_Gesture.pdf\u0026Expires=1733257089\u0026Signature=Q4J~jSJlp60GaokrNgOBn6IGjj1QHDn2oKxDq8t3ukSAJbEfrYtvf12wcXSy1y6Xet7VzZR3iRQIdW~TR3oauG8lx-l1Q0fCwF4A3Sjz8fAJ7SwM1ntoJ8hTMJExQ-4NGuvBypHhaLzuw6fujoqKCb73OwZ9wHYgRG6rUDG1pwF235faxMFT4giUZWqkTCWe6a5zArWNz~4UnftUeqYcq9vmXYzqHQCun8GUDYemGmhhpT6ufRM1SZZ5gqISPHtB2zrzJ~d1x-gYCKWP22ai4ziJ14ZmP1-VLklvqYKgNh90uUPVXnGbn-6ysiC9Pun9wzhIovdVY5ksigmLPJI6gQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

Human neonates are thought to have a broad template for faces at birth and prefer face-like to non-face-like stimuli. To better compare developmental trajectories of face processing phylogenetically, here, we investigated preferences for face-like stimuli in infant rhesus macaques using photographs of real faces. We presented infant macaques aged 15-25 days with human, macaque and abstract faces with both normal and linear arrangements of facial features and measured infants' gaze durations, number of fixations and latency to look to each face using eye-tracking technology. There was an overall preference for normal over linear facial arrangements for abstract and monkey faces but not human faces. Moreover, infant macaques looked less at monkey faces than at abstract or human faces.

Further, carefully controlled studies are required to ascertain whether infant macaques' face template can be considered as broad as human infants' face template.","publication_date":{"day":null,"month":null,"year":2009,"errors":{}},"publication_name":"Infant and Child Development","grobid_abstract_attachment_id":32697880},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628187/Sensitivity_to_First_Order_Relations_of_Facial_Elements_in_Infant_Rhesus_Macaques","translated_internal_url":"","created_at":"2014-01-06T22:26:16.662-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697880,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697880/thumbnails/1.jpg","file_name":"published.pdf","download_url":"https://www.academia.edu/attachments/32697880/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Sensitivity_to_First_Order_Relations_of.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697880/published-libre.pdf?1391130821=\u0026response-content-disposition=attachment%3B+filename%3DSensitivity_to_First_Order_Relations_of.pdf\u0026Expires=1733257089\u0026Signature=Sr5eJWK35oKIz0CdOS0C3OYFI~fnagAccY8H8G6bJ6D-cYzgvUAApQJmjNstCQIq3x0MFdTzr290sVE7GprCQFh5xhBKflMwqwXKOCgOWWHge9OZ9j58-hsIqjol6zympnyhIPh4ospshYh-vRpepcbUsJYOAO0P7GLfaaj~XUb9GkiQaCrQY8Q-ajYasSZtixZB-1WU1TWZxa1PhVdaBMR2D1ZC8e~1h~~r7uItzW2q2RQ~zTwvoucn0h2xr8Gej96cq7fx3cTr3QXUgUxc3kFL5ofJf3dl1DL9TfsGe2cgK9GVw5jPqFgcKWiFYBE5s7nTJzjnqRPP-VWVaxSxJw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Sensitivity_to_First_Order_Relations_of_Facial_Elements_in_Infant_Rhesus_Macaques","translated_slug":"","page_count":11,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697880,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697880/thumbnails/1.jpg","file_name":"published.pdf","download_url":"https://www.academia.edu/attachments/32697880/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Sensitivity_to_First_Order_Relations_of.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697880/published-libre.pdf?1391130821=\u0026response-content-disposition=attachment%3B+filename%3DSensitivity_to_First_Order_Relations_of.pdf\u0026Expires=1733257089\u0026Signature=Sr5eJWK35oKIz0CdOS0C3OYFI~fnagAccY8H8G6bJ6D-cYzgvUAApQJmjNstCQIq3x0MFdTzr290sVE7GprCQFh5xhBKflMwqwXKOCgOWWHge9OZ9j58-hsIqjol6zympnyhIPh4ospshYh-vRpepcbUsJYOAO0P7GLfaaj~XUb9GkiQaCrQY8Q-ajYasSZtixZB-1WU1TWZxa1PhVdaBMR2D1ZC8e~1h~~r7uItzW2q2RQ~zTwvoucn0h2xr8Gej96cq7fx3cTr3QXUgUxc3kFL5ofJf3dl1DL9TfsGe2cgK9GVw5jPqFgcKWiFYBE5s7nTJzjnqRPP-VWVaxSxJw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

This rhythm is critical to speech perception. Some have suggested that the speech rhythm evolved de novo in humans. An alternative account -the one we explored here -is that the rhythm of speech evolved through the modification of rhythmic facial expressions. We tested this idea by investigating the structure and development of macaque monkey lipsmacks and found that their developmental trajectory is strikingly similar to the one that leads from human infant babbling to adult speech. Specifically, we show that: (1) younger monkeys produce slower, more variable mouth movements and as they get older, these movements become faster and less variable; and (2) this developmental pattern does not occur for another cyclical mouth movement -chewing. These patterns parallel human developmental patterns for speech and chewing. They suggest that, in both species, the two types of rhythmic mouth movements use different underlying neural circuits that develop in different ways. Ultimately, both lipsmacking and speech converge on a 5 Hz rhythm that represents the frequency that characterizes the speech rhythm of human adults. We conclude that monkey lipsmacking and human speech share a homologous developmental mechanism, lending strong empirical support to the idea that the human speech rhythm evolved from the rhythmic facial expressions of our primate ancestors.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Developmental Science","grobid_abstract_attachment_id":32697868},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628156/Monkey_lipsmacking_develops_like_the_human_speech_rhythm","translated_internal_url":"","created_at":"2014-01-06T22:25:12.953-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697868,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697868/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697868/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Monkey_lipsmacking_develops_like_the_hum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697868/full_text-libre.pdf?1391197643=\u0026response-content-disposition=attachment%3B+filename%3DMonkey_lipsmacking_develops_like_the_hum.pdf\u0026Expires=1733257089\u0026Signature=KzAA3ttzdOQlqr871YB0qC4F8T4MfrZkp0hScGjyxuMaHua~kgG3gv1xw-Mt54KblQgYdImoaBAt0w4QT~WFIE~n3M6iiJ6fnrOHYoAXYV6wYLFWDnYuB4-4-jWpWZ6EsEEp8cZA0u1p9fYiv-CBy49~4E35QsBTTr40Um9kDpgF52T1oIGfIuAAgXgBapycbqJSxII1XUAuBdnmauRrTxhHMoRPcv8CS5S1Ap7w3ilmNztNV7YYIIBEGLmNTbTnfrDkgOwI9MdcTn-FEJjBfjwLgz-lxJ7o6kJ9DY4v0IDTxYVqus95up2qXinNBEQ8-WkglpvbXXlLmKS4dn3Zdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Monkey_lipsmacking_develops_like_the_human_speech_rhythm","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697868,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697868/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697868/download_file?st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Monkey_lipsmacking_develops_like_the_hum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697868/full_text-libre.pdf?1391197643=\u0026response-content-disposition=attachment%3B+filename%3DMonkey_lipsmacking_develops_like_the_hum.pdf\u0026Expires=1733257089\u0026Signature=KzAA3ttzdOQlqr871YB0qC4F8T4MfrZkp0hScGjyxuMaHua~kgG3gv1xw-Mt54KblQgYdImoaBAt0w4QT~WFIE~n3M6iiJ6fnrOHYoAXYV6wYLFWDnYuB4-4-jWpWZ6EsEEp8cZA0u1p9fYiv-CBy49~4E35QsBTTr40Um9kDpgF52T1oIGfIuAAgXgBapycbqJSxII1XUAuBdnmauRrTxhHMoRPcv8CS5S1Ap7w3ilmNztNV7YYIIBEGLmNTbTnfrDkgOwI9MdcTn-FEJjBfjwLgz-lxJ7o6kJ9DY4v0IDTxYVqus95up2qXinNBEQ8-WkglpvbXXlLmKS4dn3Zdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

To test whether a similar preference for female faces exists in other primates, we presented nursery-reared infant rhesus macaques with photographs of macaque faces and human faces. At \u003c1 month old, infant macaques preferentially oriented towards female macaque faces when faces were presented upright. No preference for female human faces was found. At 9 months old, infants failed to show a visual preference for female macaque faces or female human faces, although they showed significantly more lipsmacking responses at female human faces. Compared to human infants, macaques appear to have stronger predispositions early in life but this preference may nonetheless be amendable to experience.

Previous studies have demonstrated some resemblance between stereotypy in captive animals and in humans, including the involvement of neurological malfunctions that lead to the expression of stereotypies. This malfunction can be evaluated through the use of neuropsychological tasks that assess perseveration as implying a failure of the basal ganglia (BG) to operate properly. Other studies, in contrast, have suggested that stereotypies are the product of neurologically intact individuals reacting to the abnormal nature of their surroundings, and are possibly characterized by an adaptive feature that enables the subject to cope with such adversity. Employing neuropsychological tests and also measuring the levels of fecal corticoids in captive rhesus macaques, we tested the hypothesis that stereotypies are related both to brain pathology and to a coping mechanism with stress, resembling accounts by autistic individuals exhibiting basal ganglia malfunction, and who report a sense of relief when performing stereotypies. Self-directed and fine-motor stereotypies exhibited by the monkeys were positively correlated with perseveration, suggesting BG malfunction; while self-directed stereotypies were also negatively correlated with an increase in fecal corticoids following a stress challenge, suggesting a related coping mechanism. We therefore suggest that not all repetitive, unvarying, and apparently functionless behaviors should be regarded as one homogeneous group of stereotypic behaviors; and that, reflecting reports from autistic individuals, self-directed stereotypies in captive rhesus monkeys are related both to brain pathology, and to an adaptive mechanism that allows those that express them to better cope with acute stressors.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Behavioral Brain Research","grobid_abstract_attachment_id":32697852},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628140/Some_stereotypic_behaviors_in_rhesus_macaques_Macaca_mulatta_are_correlated_with_both_perseveration_and_the_ability_to_cope_with_acute_stressors","translated_internal_url":"","created_at":"2014-01-06T22:22:57.872-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697852,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697852/thumbnails/1.jpg","file_name":"behavbrainres.pdf","download_url":"https://www.academia.edu/attachments/32697852/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Some_stereotypic_behaviors_in_rhesus_mac.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697852/behavbrainres-libre.pdf?1391153545=\u0026response-content-disposition=attachment%3B+filename%3DSome_stereotypic_behaviors_in_rhesus_mac.pdf\u0026Expires=1733257090\u0026Signature=IorOphwTHurJndYTZ5DD9ZXPd2GK3WbVe7huBxGIdjACJGMRYXWPPoCWMPJgTe9OcBEQ1o8zFntkNcZrbxwMLdPmMhP4h~h7spWyEp8n7Oa~YALOEg4mLeqjNNRk8L~xrVZZ2d3084IsRsIAWtGN5KM3uOMSmVxAj4ncKrm6DSRa5Uyer~zSQ3cHWo84lSE00ygh-BRWlHzZvJTndUsZOONB1v-N-AY2OBWoREVEjRmNTi8Ibo1X-Uvni4jegm6ikFUM9SaDC11P9DDD2WQz8BGEUjHs86vUTfDkDAn8mKJ8SwB455lRmkVXrBvZpza4mp-KPr318-4r~OML~xXcXA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Some_stereotypic_behaviors_in_rhesus_macaques_Macaca_mulatta_are_correlated_with_both_perseveration_and_the_ability_to_cope_with_acute_stressors","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697852,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697852/thumbnails/1.jpg","file_name":"behavbrainres.pdf","download_url":"https://www.academia.edu/attachments/32697852/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Some_stereotypic_behaviors_in_rhesus_mac.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697852/behavbrainres-libre.pdf?1391153545=\u0026response-content-disposition=attachment%3B+filename%3DSome_stereotypic_behaviors_in_rhesus_mac.pdf\u0026Expires=1733257090\u0026Signature=IorOphwTHurJndYTZ5DD9ZXPd2GK3WbVe7huBxGIdjACJGMRYXWPPoCWMPJgTe9OcBEQ1o8zFntkNcZrbxwMLdPmMhP4h~h7spWyEp8n7Oa~YALOEg4mLeqjNNRk8L~xrVZZ2d3084IsRsIAWtGN5KM3uOMSmVxAj4ncKrm6DSRa5Uyer~zSQ3cHWo84lSE00ygh-BRWlHzZvJTndUsZOONB1v-N-AY2OBWoREVEjRmNTi8Ibo1X-Uvni4jegm6ikFUM9SaDC11P9DDD2WQz8BGEUjHs86vUTfDkDAn8mKJ8SwB455lRmkVXrBvZpza4mp-KPr318-4r~OML~xXcXA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

However, attributing the same significance to all of these repetitive, unvarying and apparently functionless behaviours may be misleading, as some behaviours may be better indicators of stress than others. Previous studies have demonstrated that the affective state of the individual can be inferred from its bias in appraising neutral stimuli in its environment. Therefore, in the present study, in order to assess the emotional state of stereotyping individuals, 16 captive tufted capuchins (Cebus apella) were tested on a judgment bias paradigm and their faecal corticoid levels were measured in order to assess the intensity of the emotional state. Capuchins with higher levels of stereotypic head twirls exhibited a negative bias while judging ambiguous stimuli and had higher levels of faecal corticoids compared to subjects with lower levels of head twirls. Levels of stereotypic pacing, however, were not correlated with the monkeys' emotional state. This study is the first to reveal a positive correlation between levels of stereotypic behaviour and a 'pessimistic'-like judgment bias in a non-human primate by employing a recently developed cognitive approach. Combining cognitive tests that evaluate the animals' affective valence (positive or negative) with hormonal measurements that provide information on the strength of the emotional state conduces to a better understanding of the animals' affective state and therefore to their well-being.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Animal Cognition","grobid_abstract_attachment_id":32697835},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628124/Stereotypic_head_twirls_but_not_pacing_are_related_to_a_pessimistic_like_judgment_bias_among_captive_tufted_capuchins_Cebus_apella_","translated_internal_url":"","created_at":"2014-01-06T22:20:07.984-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697835,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697835/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697835/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Stereotypic_head_twirls_but_not_pacing_a.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697835/full_text-libre.pdf?1391230766=\u0026response-content-disposition=attachment%3B+filename%3DStereotypic_head_twirls_but_not_pacing_a.pdf\u0026Expires=1733257090\u0026Signature=dINMvoTBjZWSFx~rsQvgcmji7kL8pslAWv-IfTW5DOXqBdSRIv8Z~FK9o5ErshE1vLCum4FYKgduXOUjE65lSjrIw1HCh7t0p3Ij~fOHblT7LOVDLjaVB089rSql0cj5TaWS~LzIWR~IWYFer1kUOQuulCYI0y7aj0WtBnJzyYj25eQN-j3pFQL6Cdmjo8WxQz1iQeAHk5F0LfZVoTME04sLf4s~SIQXkhr8Sgh~xwlS9-TyYjNixh~gudeb6GeDatxFxALzH-PS0PolJQWkaTH0Ntqjx~sZbhbI25YkMle5-Cs2XzSpdo7upXw2xIcHoqYI0ymwg8JrcYMag7yvSA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Stereotypic_head_twirls_but_not_pacing_are_related_to_a_pessimistic_like_judgment_bias_among_captive_tufted_capuchins_Cebus_apella_","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697835,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697835/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697835/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Stereotypic_head_twirls_but_not_pacing_a.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697835/full_text-libre.pdf?1391230766=\u0026response-content-disposition=attachment%3B+filename%3DStereotypic_head_twirls_but_not_pacing_a.pdf\u0026Expires=1733257090\u0026Signature=dINMvoTBjZWSFx~rsQvgcmji7kL8pslAWv-IfTW5DOXqBdSRIv8Z~FK9o5ErshE1vLCum4FYKgduXOUjE65lSjrIw1HCh7t0p3Ij~fOHblT7LOVDLjaVB089rSql0cj5TaWS~LzIWR~IWYFer1kUOQuulCYI0y7aj0WtBnJzyYj25eQN-j3pFQL6Cdmjo8WxQz1iQeAHk5F0LfZVoTME04sLf4s~SIQXkhr8Sgh~xwlS9-TyYjNixh~gudeb6GeDatxFxALzH-PS0PolJQWkaTH0Ntqjx~sZbhbI25YkMle5-Cs2XzSpdo7upXw2xIcHoqYI0ymwg8JrcYMag7yvSA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="5628106"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/5628106/Can_Traditions_Emerge_from_the_Interaction_of_Stimulus_Enhancement_and_Reinforcement_Learning_An_Experimental_Model"><img alt="Research paper thumbnail of Can Traditions Emerge from the Interaction of Stimulus Enhancement and Reinforcement Learning?

Here, we report for the first time how social group cohesion is affected by fur rubbing in tufted capuchin monkeys. Fifteen captive capuchins were each observed six times for 45 min, three times following the provision of materials typically used for fur rubbing (onion) and three times following control food items (apple). When compared with the apple condition, monkeys significantly increased proximity to one another in the first 15 min of the onion condition, which is when most fur rubbing took place. Moreover, monkeys were more likely to spend time in groups when fur rubbing but less likely to spend time in groups when manipulating the onion in other ways. In subsequent periods monkeys were less likely to be in proximity to one another in the onion condition compared with the apple condition. Aggression between group members was elevated whereas affiliation was decreased throughout the onion condition. In short, capuchins spent more time further apart and engaged in more aggressive acts and shorter affiliative acts following fur-rubbing bouts. It is possible that these differences in behavior could be owing to differences in how the monkeys competed for and interacted with the items presented in each condition rather than due to fur rubbing as such. Alternatively, fur rubbing with pungent materials might interfere with olfactory cues used to regulate social interactions within a group and thereby cause increased levels of aggression.

Humans are adept at using facial similarity to recognize likely kin, and there is evidence that nonhuman primates are also able to use facial similarity to make judgments about kinship. However, if and how nonhuman primate faces actually contain kinship information remains unclear. To test whether there is objectively measurable facial similarity in related nonhuman primates, we compared facial measurements from related (paternal half-sisters) and unrelated adult female rhesus macaques (Macaca mulatta). Facial measurements were first summarized into 5 factors using a principal component analysis. Differences in these factors between the faces of related macaques were compared with differences between the faces of random unrelated macaques and of age-matched unrelated macaques. The difference in facial measurements between related macaques was significantly smaller than the difference in facial measurements of either group of unrelated macaques, constituting an objective measure of facial similarity in macaque kin. These results indicate that kinship information is contained in the rhesus macaque face and suggest that nonhuman primates may rely in part on facial similarity to distinguish kin.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Journal of Comparative Psychology","grobid_abstract_attachment_id":32697770},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627921/Evidence_for_Kinship_Information_Contained_in_the_Rhesus_Macaque_Macaca_mulatta_Face","translated_internal_url":"","created_at":"2014-01-06T22:04:40.414-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697770,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697770/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697770/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Evidence_for_Kinship_Information_Contain.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697770/fulltext-libre.pdf?1391210088=\u0026response-content-disposition=attachment%3B+filename%3DEvidence_for_Kinship_Information_Contain.pdf\u0026Expires=1733257090\u0026Signature=ZJPQo-1qSzWMOTWq3oG5j-~HAa3KKLT~8fjWTbIPRz2HiBOg0ApiD5hID3l5Ul~HKBKbQeJRppq~gnFIhZhq1gspoELeFkJkO3WmODgszPrcXyUS9fXaPQ0j3hqgDvWqk8JcMxqBX0b05gBGxHmbPjqlgFyDUvYKKGb6Pa54Kp4QHRDgmBenBFc-tlrgvQ166puKSQ9gpT~LYDMwJM4Npl35OZtMESIjGby5iWYbzq8XposoDJ1spDZJqFoBtv6LaZa8a-w098ZRf6~t3m~eff53S~XNd-dBNG1dYvS0IYgS1uSLTiiqmR1VKn5V0xyBxzsY8VU4k5HEXAueSGvDXg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Evidence_for_Kinship_Information_Contained_in_the_Rhesus_Macaque_Macaca_mulatta_Face","translated_slug":"","page_count":6,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697770,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697770/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697770/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Evidence_for_Kinship_Information_Contain.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697770/fulltext-libre.pdf?1391210088=\u0026response-content-disposition=attachment%3B+filename%3DEvidence_for_Kinship_Information_Contain.pdf\u0026Expires=1733257090\u0026Signature=ZJPQo-1qSzWMOTWq3oG5j-~HAa3KKLT~8fjWTbIPRz2HiBOg0ApiD5hID3l5Ul~HKBKbQeJRppq~gnFIhZhq1gspoELeFkJkO3WmODgszPrcXyUS9fXaPQ0j3hqgDvWqk8JcMxqBX0b05gBGxHmbPjqlgFyDUvYKKGb6Pa54Kp4QHRDgmBenBFc-tlrgvQ166puKSQ9gpT~LYDMwJM4Npl35OZtMESIjGby5iWYbzq8XposoDJ1spDZJqFoBtv6LaZa8a-w098ZRf6~t3m~eff53S~XNd-dBNG1dYvS0IYgS1uSLTiiqmR1VKn5V0xyBxzsY8VU4k5HEXAueSGvDXg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195994,"url":"http://dx.doi.org/10.1037/a0025081"}]}, dispatcherData: dispatcherData });

Newborn infants are also capable of exhibiting a range of facial expressions. Identification of the neural underpinnings of these capacities represents a formidable challenge in understanding social development. One possible neuronal substrate is the mirror-neuron system assumed to activate shared motor cortical representations for both observation and production of actions. We tested this hypothesis by recording scalp EEG from 1-to 7-day-old newborn rhesus macaques who were observing and producing facial gestures. We found that 5-6 Hz EEG activity was suppressed both when the infants produced facial gestures and while they were observing facial gestures of a human experimenter, but not when they were observing nonbiological stimuli. These findings demonstrate the presence of neural reactivity for biological, communicatively relevant stimuli, which may be a likely signature of neuronal mirroring. The basic elements of the mirror-neuron system appear to operate from the very first days of life and contribute to the encoding of socially relevant stimuli. ■","publication_name":"Journal of Cognitive Neuroscience","grobid_abstract_attachment_id":32697777},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627920/Distinct_EEG_Amplitude_Suppression_to_Facial_Gestures_as_Evidence_for_a_Mirror_Mechanism_in_Newborn_Monkeys","translated_internal_url":"","created_at":"2014-01-06T22:04:35.300-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697777,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697777/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697777/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Distinct_EEG_Amplitude_Suppression_to_Fa.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697777/full_text-libre.pdf?1391197175=\u0026response-content-disposition=attachment%3B+filename%3DDistinct_EEG_Amplitude_Suppression_to_Fa.pdf\u0026Expires=1733257090\u0026Signature=ATU7CoTxps8YP2nLiS29ICwkvazS-mo81JyvHJ9j~OnQUuCEEIwy3eq41iFljLBAQHEHFlnCuNBoYVxlnxI43EWD60ydV4UnM2FhQzXY82oaB4X-hLfnU00NqbGFaJbyEfmvcVzUb6~JgA~iDl-0PbLbuHDWlnsxJdc4wP47NtVNZs6BzkHo7L5s0iLZzGVb8PwDGaZSMCATFSQggY-mhRO9BzzjghfOH5yzgErOG6IW7o4LtZmwQUTDEsBizDliKOvT19X8k-D6qt-mcZUQZD7LWuTeuM89MovcuZQMJlTLril9mLjhUgXwXUzWTC7Grq4pRa7C-v00OQYPNGfdLA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Distinct_EEG_Amplitude_Suppression_to_Facial_Gestures_as_Evidence_for_a_Mirror_Mechanism_in_Newborn_Monkeys","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697777,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697777/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697777/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Distinct_EEG_Amplitude_Suppression_to_Fa.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697777/full_text-libre.pdf?1391197175=\u0026response-content-disposition=attachment%3B+filename%3DDistinct_EEG_Amplitude_Suppression_to_Fa.pdf\u0026Expires=1733257090\u0026Signature=ATU7CoTxps8YP2nLiS29ICwkvazS-mo81JyvHJ9j~OnQUuCEEIwy3eq41iFljLBAQHEHFlnCuNBoYVxlnxI43EWD60ydV4UnM2FhQzXY82oaB4X-hLfnU00NqbGFaJbyEfmvcVzUb6~JgA~iDl-0PbLbuHDWlnsxJdc4wP47NtVNZs6BzkHo7L5s0iLZzGVb8PwDGaZSMCATFSQggY-mhRO9BzzjghfOH5yzgErOG6IW7o4LtZmwQUTDEsBizDliKOvT19X8k-D6qt-mcZUQZD7LWuTeuM89MovcuZQMJlTLril9mLjhUgXwXUzWTC7Grq4pRa7C-v00OQYPNGfdLA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195993,"url":"http://dx.doi.org/10.1162/jocn_a_00198"}]}, dispatcherData: dispatcherData });

The results are consistent with other findings suggesting that monkeys are not capable of passing a mark test and imply that face and body recognition rely on the same cognitive abilities.","internal_url":"https://www.academia.edu/5627919/A_modified_mark_test_for_own_body_recognition_in_pig_tailed_macaques_Macaca_nemestrina","translated_internal_url":"","created_at":"2014-01-06T22:04:34.359-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697785,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697785/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697785/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"A_modified_mark_test_for_own_body_recogn.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697785/fulltext-libre.pdf?1391162329=\u0026response-content-disposition=attachment%3B+filename%3DA_modified_mark_test_for_own_body_recogn.pdf\u0026Expires=1733257090\u0026Signature=X2H9xJmv2YJLIfXjBqF2Xk3ULEfHvc7gOX9yu9~STohcYFQFqeiTGHsj-Wn4SZy0I8zIbe-4pa00CHg7VaN9Jj~pEJQso~Sho63SLJTpHI1N6yL95XYRV2H6SP7Q4z6NSrK~JOKAaK306AR0DXRIejg2F-4bz6bN68Cpl2ZdfgugPCo0CqOpaV2~4JBC30~DFtdsWF9UKRFBL6--QZVfC6lLguS~KsFwLNqh6fY6yFlBTQOPurksodkWYiNkvnYzK65HKsZ4NTW1l7GJx-SnqB5vJZvhQzFknGekIfDG6EXmNzi9oV~41XSHfBIGhZERgAzCcbO~mpBBC7VUref6ZQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"A_modified_mark_test_for_own_body_recognition_in_pig_tailed_macaques_Macaca_nemestrina","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697785,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697785/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697785/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"A_modified_mark_test_for_own_body_recogn.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697785/fulltext-libre.pdf?1391162329=\u0026response-content-disposition=attachment%3B+filename%3DA_modified_mark_test_for_own_body_recogn.pdf\u0026Expires=1733257090\u0026Signature=X2H9xJmv2YJLIfXjBqF2Xk3ULEfHvc7gOX9yu9~STohcYFQFqeiTGHsj-Wn4SZy0I8zIbe-4pa00CHg7VaN9Jj~pEJQso~Sho63SLJTpHI1N6yL95XYRV2H6SP7Q4z6NSrK~JOKAaK306AR0DXRIejg2F-4bz6bN68Cpl2ZdfgugPCo0CqOpaV2~4JBC30~DFtdsWF9UKRFBL6--QZVfC6lLguS~KsFwLNqh6fY6yFlBTQOPurksodkWYiNkvnYzK65HKsZ4NTW1l7GJx-SnqB5vJZvhQzFknGekIfDG6EXmNzi9oV~41XSHfBIGhZERgAzCcbO~mpBBC7VUref6ZQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195992,"url":"http://www.springerlink.com/index/p347vh2k114r4h55.pdf"}]}, dispatcherData: dispatcherData });

The present study investigates how different types of sensory information affect capuchins' ability to locate hidden food. In two experiments, capuchins were presented with two cups, one baited and one empty. Monkeys were given visual, acoustic, or acoustic-visual information related to the baited cup, the empty cup, or both baited and empty cup. Results show that capuchins spontaneously used visual information to locate food, and that information indicating presence and absence of food led to higher success rates than information indicating only absence of food. In contrast, acoustic information did not lead to success rates above chance levels and failed to enhance performance in combination with visual information. Capuchins spontaneously avoided a visually empty cup, but they did not appear to associate sounds with either the presence or absence of food. Being able to locate food items with the aid of acoustic cues might be a learned process that requires interactive experiences with the task's contingencies.","publication_date":{"day":null,"month":null,"year":2009,"errors":{}},"publication_name":"Journal of Comparative Psychology","grobid_abstract_attachment_id":32697795},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627917/Tufted_Capuchin_Monkeys_Cebus_apella_Spontaneously_Use_Visual_but_Not_Acoustic_Information_to_Find_Hidden_Food_Items","translated_internal_url":"","created_at":"2014-01-06T22:04:32.736-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697795,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697795/thumbnails/1.jpg","file_name":"JCP_published.pdf","download_url":"https://www.academia.edu/attachments/32697795/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697795/JCP_published-libre.pdf?1391169371=\u0026response-content-disposition=attachment%3B+filename%3DTufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf\u0026Expires=1733257090\u0026Signature=UShXrKmW4fFfksSi79Yicv6cAmYL4UAKv4r~pnYtHauECSZ2szUKjvNu8ynM2Iq5DucloiIRgBn0X-tyT-8aWXzsRYwLB3cNtjcymUvWSIaP0wWpvbaAr2irCcEskWW~zqz5IwXJ~4t5XTqzLWEHS1eApHQvSQk45GUmT~xN9zQ3O4QA0s0FvOCb7oWMu3dXLhutUvQGn5fNHS6PjVP5sxeEBuzd3NaByY8wUwdJ5AEC0z~rV072J-EPcjrtgZmv4aVKTzrbh5QZvQlM25xNWSA~q0VBZmVeP71uMH1ve4YcjVcA54YFYtqjA00oWXvErhjAEBH8EWmqLcG5Z7-wnw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Tufted_Capuchin_Monkeys_Cebus_apella_Spontaneously_Use_Visual_but_Not_Acoustic_Information_to_Find_Hidden_Food_Items","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697795,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697795/thumbnails/1.jpg","file_name":"JCP_published.pdf","download_url":"https://www.academia.edu/attachments/32697795/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697795/JCP_published-libre.pdf?1391169371=\u0026response-content-disposition=attachment%3B+filename%3DTufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf\u0026Expires=1733257090\u0026Signature=UShXrKmW4fFfksSi79Yicv6cAmYL4UAKv4r~pnYtHauECSZ2szUKjvNu8ynM2Iq5DucloiIRgBn0X-tyT-8aWXzsRYwLB3cNtjcymUvWSIaP0wWpvbaAr2irCcEskWW~zqz5IwXJ~4t5XTqzLWEHS1eApHQvSQk45GUmT~xN9zQ3O4QA0s0FvOCb7oWMu3dXLhutUvQGn5fNHS6PjVP5sxeEBuzd3NaByY8wUwdJ5AEC0z~rV072J-EPcjrtgZmv4aVKTzrbh5QZvQlM25xNWSA~q0VBZmVeP71uMH1ve4YcjVcA54YFYtqjA00oWXvErhjAEBH8EWmqLcG5Z7-wnw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195990,"url":"http://dx.doi.org/10.1037/a0013128"}]}, dispatcherData: dispatcherData });

A greater frequency of GFR was found in females compared to males, and two hypotheses for this finding are discussed.","internal_url":"https://www.academia.edu/5627912/Do_facial_gestures_visibility_or_speed_of_movement_influence_gaze_following_responses_in_pigtail_macaques","translated_internal_url":"","created_at":"2014-01-06T22:04:28.183-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697801,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697801/thumbnails/1.jpg","file_name":"final_published.pdf","download_url":"https://www.academia.edu/attachments/32697801/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Do_facial_gestures_visibility_or_speed_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697801/final_published-libre.pdf?1391136316=\u0026response-content-disposition=attachment%3B+filename%3DDo_facial_gestures_visibility_or_speed_o.pdf\u0026Expires=1733257090\u0026Signature=Bm7ynuTPSHT56J0Y2q0451VOtlbEDzouc48yJR6DOI17gzk~ult3i0lPiRncd8EAj02~F-07Lgcr4uy0e2fwZvxCfVtj~nUubZwfBNfHHGzYwDimgSoQkyqw-nHaBSz8oB6rMqJ7C0SOqCs7Fw4kcPI8kdJ5QFtQFKHFKEmIwI9O7mAdUffwy9TCuq4c3iznTzU0WkxHjN14jpuN0R1K1SiwLr~XNQ3VbHOxg3CmWdIx3CEtUMciQDcoYG6cLtZY78hO3DExL7ZQqeMWh-dyKx5L~yey7EjR9fGXyitI6Kg~GiweBN2~F9oRf6zZZ8wtEll~GbxT3qgqVUt435P0KQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Do_facial_gestures_visibility_or_speed_of_movement_influence_gaze_following_responses_in_pigtail_macaques","translated_slug":"","page_count":4,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697801,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697801/thumbnails/1.jpg","file_name":"final_published.pdf","download_url":"https://www.academia.edu/attachments/32697801/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Do_facial_gestures_visibility_or_speed_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697801/final_published-libre.pdf?1391136316=\u0026response-content-disposition=attachment%3B+filename%3DDo_facial_gestures_visibility_or_speed_o.pdf\u0026Expires=1733257090\u0026Signature=Bm7ynuTPSHT56J0Y2q0451VOtlbEDzouc48yJR6DOI17gzk~ult3i0lPiRncd8EAj02~F-07Lgcr4uy0e2fwZvxCfVtj~nUubZwfBNfHHGzYwDimgSoQkyqw-nHaBSz8oB6rMqJ7C0SOqCs7Fw4kcPI8kdJ5QFtQFKHFKEmIwI9O7mAdUffwy9TCuq4c3iznTzU0WkxHjN14jpuN0R1K1SiwLr~XNQ3VbHOxg3CmWdIx3CEtUMciQDcoYG6cLtZY78hO3DExL7ZQqeMWh-dyKx5L~yey7EjR9fGXyitI6Kg~GiweBN2~F9oRf6zZZ8wtEll~GbxT3qgqVUt435P0KQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195986,"url":"http://www.springerlink.com/index/c21lk08025661548.pdf"}]}, dispatcherData: dispatcherData });

Twenty-two stumptail macaques (Macaca arctoides) were presented with video clips of either yawns or control mouth movements by conspecifics. At a group level, monkeys yawned significantly more often during and just after the yawn tape than the control tape. Supplementary analysis revealed that the yawn tape also elicited significantly more self-directed scratching responses than the control tape, which suggests that yawning might have been caused by tension arising from viewing the yawn tape. Understanding to what extent the observed effect resembles contagious yawning as found in humans and chimpanzees requires more detailed experimentation.","publication_date":{"day":null,"month":null,"year":2006,"errors":{}},"publication_name":"Biology Letters","grobid_abstract_attachment_id":32697698},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627911/Video_induced_yawning_in_stumptail_macaques_Macaca_arctoides","translated_internal_url":"","created_at":"2014-01-06T22:04:27.319-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697698,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697698/thumbnails/1.jpg","file_name":"Paukner_macaca.pdf","download_url":"https://www.academia.edu/attachments/32697698/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Video_induced_yawning_in_stumptail_macaq.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697698/Paukner_macaca-libre.pdf?1391129359=\u0026response-content-disposition=attachment%3B+filename%3DVideo_induced_yawning_in_stumptail_macaq.pdf\u0026Expires=1733257090\u0026Signature=AUlHI4vA-Nc9RVH-x2TxPx0seLbTLm4xTBycYi4onmmlSrjNW1Hs57Jq4sOtDizDPJMVQm-osK7jSrOuPksJ9YiOFPDJ8HiL7FMGHdldFlFdEfXGmDbbVESU7Lsh6N4~SrS9KlWjm8Ow2V~BbBYDtcm83TGZJN9ztp5J1ESLjOXLbAL7Z2to7dLIczA43tLtQ0gFDF0Dw4yLZrWUBH2dDFexp32wTcwHzPmptjpGfOJPHhLlVf8Izgjj9LsPhDe2nq-5aLKFXl1Wes26BHJDe7F~OF8fHSHhFeyqphBKCI9mug2sO01Q-uqwsdowg8CMfyOIVdypX5GlqqxWUOIRqw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Video_induced_yawning_in_stumptail_macaques_Macaca_arctoides","translated_slug":"","page_count":3,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697698,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697698/thumbnails/1.jpg","file_name":"Paukner_macaca.pdf","download_url":"https://www.academia.edu/attachments/32697698/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Video_induced_yawning_in_stumptail_macaq.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697698/Paukner_macaca-libre.pdf?1391129359=\u0026response-content-disposition=attachment%3B+filename%3DVideo_induced_yawning_in_stumptail_macaq.pdf\u0026Expires=1733257090\u0026Signature=AUlHI4vA-Nc9RVH-x2TxPx0seLbTLm4xTBycYi4onmmlSrjNW1Hs57Jq4sOtDizDPJMVQm-osK7jSrOuPksJ9YiOFPDJ8HiL7FMGHdldFlFdEfXGmDbbVESU7Lsh6N4~SrS9KlWjm8Ow2V~BbBYDtcm83TGZJN9ztp5J1ESLjOXLbAL7Z2to7dLIczA43tLtQ0gFDF0Dw4yLZrWUBH2dDFexp32wTcwHzPmptjpGfOJPHhLlVf8Izgjj9LsPhDe2nq-5aLKFXl1Wes26BHJDe7F~OF8fHSHhFeyqphBKCI9mug2sO01Q-uqwsdowg8CMfyOIVdypX5GlqqxWUOIRqw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195985,"url":"http://www.baillement.com/replication/Paukner_macaca.pdf"}]}, dispatcherData: dispatcherData });

This observed decrease in group cohesion may be attributable to increased intragroup competition for fur-rub material rather than being a direct effect of fur rubbing itself. To test this hypothesis, we separated individual tufted monkeys (Cebus apella) from their social group and provided them with fur-rub material or control material, thereby avoiding intragroup competition. After engagement with materials, we released subjects back into their social group and observed their subsequent interactions with group members. We found that subjects were more likely to encounter aggression and less likely to receive affiliation from others in the fur-rub condition than in the control condition. These results support the idea that fur rubbing carries social after-effects for capuchin monkeys. The precise mechanisms of the observed effects remain to be clarified in future studies.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Primates","grobid_abstract_attachment_id":32697909},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628217/Social_after_effects_of_fur_rubbing_in_tufted_capuchin_monkeys_Cebus_apella_increased_antagonism_and_reduced_affiliation","translated_internal_url":"","created_at":"2014-01-06T22:29:23.223-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697909,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697909/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697909/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Social_after_effects_of_fur_rubbing_in_t.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697909/fulltext-libre.pdf?1391099032=\u0026response-content-disposition=attachment%3B+filename%3DSocial_after_effects_of_fur_rubbing_in_t.pdf\u0026Expires=1733257089\u0026Signature=FXn7jgpn6vxaC~pb7RpnDpSl3SwywuCsaRZrn2JUN5NuQC2T7trrTmuoYVULPUF4rLsQhSz01reH3r-q6S~-VW6o4xLXOgrUos7AwL6pU00CqKF-i5sibhUuW3fFIr7BavT9kdQxAmbGV4Av1dIJj1OK6FEejtS-SO-M08N1rkpDCDB4JQjnReI8myOOMk5bJtkQg2wBE3UIMdxWMB3fuC726OMEkDtTmoreC1Mk1eNfsMC8lodKbKBW1W9pT25chwjnJursCkOTNGVvyMaHtVJSPAE1xQbODBQAt0vyhOQVjV30atpUsBot0QZk9PzRlfrwszanLgjtNl6NEpv86w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Social_after_effects_of_fur_rubbing_in_tufted_capuchin_monkeys_Cebus_apella_increased_antagonism_and_reduced_affiliation","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697909,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697909/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697909/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Social_after_effects_of_fur_rubbing_in_t.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697909/fulltext-libre.pdf?1391099032=\u0026response-content-disposition=attachment%3B+filename%3DSocial_after_effects_of_fur_rubbing_in_t.pdf\u0026Expires=1733257089\u0026Signature=FXn7jgpn6vxaC~pb7RpnDpSl3SwywuCsaRZrn2JUN5NuQC2T7trrTmuoYVULPUF4rLsQhSz01reH3r-q6S~-VW6o4xLXOgrUos7AwL6pU00CqKF-i5sibhUuW3fFIr7BavT9kdQxAmbGV4Av1dIJj1OK6FEejtS-SO-M08N1rkpDCDB4JQjnReI8myOOMk5bJtkQg2wBE3UIMdxWMB3fuC726OMEkDtTmoreC1Mk1eNfsMC8lodKbKBW1W9pT25chwjnJursCkOTNGVvyMaHtVJSPAE1xQbODBQAt0vyhOQVjV30atpUsBot0QZk9PzRlfrwszanLgjtNl6NEpv86w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

Recent studies have suggested that rather than being a simple reflexive-like behavior, infants exert active control over imitative responses and 'provoke' previously imitated gestures even after a delay of up to 24 h. Delayed imitation is regarded as the hallmark of a sophisticated capacity to control and flexibly engage in affective communication and has been described as an indicator of innate protoconversational readiness. However, we are not the only primates to exhibit neonatal imitation, and delayed imitation abilities may not be uniquely human. Here we report that 1-week-old infant rhesus macaques (Macaca mulatta) who show immediate imitation of a lipsmacking gesture also show delayed imitation of lipsmacking, facilitated by a tendency to refrain from lipsmacking toward a still face during baseline measurements. Individual differences in delayed imitation suggest that differentially matured cortical mechanisms may be involved, allowing some newborns macaques to actively participate in communicative exchanges from birth. Macaque infants are endowed with basic social competencies of intersubjective communication that indicate cognitive and emotional commonality between humans and macaques, which may have evolved to nurture an affective mother-infant relationship in primates.","publication_date":{"day":null,"month":null,"year":2011,"errors":{}},"publication_name":"PLoS ONE","grobid_abstract_attachment_id":32697901},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628212/Delayed_Imitation_of_Lipsmacking_Gestures_by_Infant_Rhesus_Macaques_Macaca_mulatta_","translated_internal_url":"","created_at":"2014-01-06T22:28:29.508-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697901,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697901/thumbnails/1.jpg","file_name":"journal.pone.0028848_1_.pdf","download_url":"https://www.academia.edu/attachments/32697901/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Delayed_Imitation_of_Lipsmacking_Gesture.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697901/journal.pone.0028848_1_.pdf?1389076063=\u0026response-content-disposition=attachment%3B+filename%3DDelayed_Imitation_of_Lipsmacking_Gesture.pdf\u0026Expires=1733257089\u0026Signature=Q4J~jSJlp60GaokrNgOBn6IGjj1QHDn2oKxDq8t3ukSAJbEfrYtvf12wcXSy1y6Xet7VzZR3iRQIdW~TR3oauG8lx-l1Q0fCwF4A3Sjz8fAJ7SwM1ntoJ8hTMJExQ-4NGuvBypHhaLzuw6fujoqKCb73OwZ9wHYgRG6rUDG1pwF235faxMFT4giUZWqkTCWe6a5zArWNz~4UnftUeqYcq9vmXYzqHQCun8GUDYemGmhhpT6ufRM1SZZ5gqISPHtB2zrzJ~d1x-gYCKWP22ai4ziJ14ZmP1-VLklvqYKgNh90uUPVXnGbn-6ysiC9Pun9wzhIovdVY5ksigmLPJI6gQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Delayed_Imitation_of_Lipsmacking_Gestures_by_Infant_Rhesus_Macaques_Macaca_mulatta_","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697901,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697901/thumbnails/1.jpg","file_name":"journal.pone.0028848_1_.pdf","download_url":"https://www.academia.edu/attachments/32697901/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Delayed_Imitation_of_Lipsmacking_Gesture.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697901/journal.pone.0028848_1_.pdf?1389076063=\u0026response-content-disposition=attachment%3B+filename%3DDelayed_Imitation_of_Lipsmacking_Gesture.pdf\u0026Expires=1733257089\u0026Signature=Q4J~jSJlp60GaokrNgOBn6IGjj1QHDn2oKxDq8t3ukSAJbEfrYtvf12wcXSy1y6Xet7VzZR3iRQIdW~TR3oauG8lx-l1Q0fCwF4A3Sjz8fAJ7SwM1ntoJ8hTMJExQ-4NGuvBypHhaLzuw6fujoqKCb73OwZ9wHYgRG6rUDG1pwF235faxMFT4giUZWqkTCWe6a5zArWNz~4UnftUeqYcq9vmXYzqHQCun8GUDYemGmhhpT6ufRM1SZZ5gqISPHtB2zrzJ~d1x-gYCKWP22ai4ziJ14ZmP1-VLklvqYKgNh90uUPVXnGbn-6ysiC9Pun9wzhIovdVY5ksigmLPJI6gQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

Human neonates are thought to have a broad template for faces at birth and prefer face-like to non-face-like stimuli. To better compare developmental trajectories of face processing phylogenetically, here, we investigated preferences for face-like stimuli in infant rhesus macaques using photographs of real faces. We presented infant macaques aged 15-25 days with human, macaque and abstract faces with both normal and linear arrangements of facial features and measured infants' gaze durations, number of fixations and latency to look to each face using eye-tracking technology. There was an overall preference for normal over linear facial arrangements for abstract and monkey faces but not human faces. Moreover, infant macaques looked less at monkey faces than at abstract or human faces. These results suggest that species and facial configurations affect face processing in infant macaques, and we discuss potential explanations for these findings. Further, carefully controlled studies are required to ascertain whether infant macaques' face template can be considered as broad as human infants' face template.","publication_date":{"day":null,"month":null,"year":2009,"errors":{}},"publication_name":"Infant and Child Development","grobid_abstract_attachment_id":32697880},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628187/Sensitivity_to_First_Order_Relations_of_Facial_Elements_in_Infant_Rhesus_Macaques","translated_internal_url":"","created_at":"2014-01-06T22:26:16.662-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697880,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697880/thumbnails/1.jpg","file_name":"published.pdf","download_url":"https://www.academia.edu/attachments/32697880/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Sensitivity_to_First_Order_Relations_of.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697880/published-libre.pdf?1391130821=\u0026response-content-disposition=attachment%3B+filename%3DSensitivity_to_First_Order_Relations_of.pdf\u0026Expires=1733257089\u0026Signature=Sr5eJWK35oKIz0CdOS0C3OYFI~fnagAccY8H8G6bJ6D-cYzgvUAApQJmjNstCQIq3x0MFdTzr290sVE7GprCQFh5xhBKflMwqwXKOCgOWWHge9OZ9j58-hsIqjol6zympnyhIPh4ospshYh-vRpepcbUsJYOAO0P7GLfaaj~XUb9GkiQaCrQY8Q-ajYasSZtixZB-1WU1TWZxa1PhVdaBMR2D1ZC8e~1h~~r7uItzW2q2RQ~zTwvoucn0h2xr8Gej96cq7fx3cTr3QXUgUxc3kFL5ofJf3dl1DL9TfsGe2cgK9GVw5jPqFgcKWiFYBE5s7nTJzjnqRPP-VWVaxSxJw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Sensitivity_to_First_Order_Relations_of_Facial_Elements_in_Infant_Rhesus_Macaques","translated_slug":"","page_count":11,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697880,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697880/thumbnails/1.jpg","file_name":"published.pdf","download_url":"https://www.academia.edu/attachments/32697880/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Sensitivity_to_First_Order_Relations_of.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697880/published-libre.pdf?1391130821=\u0026response-content-disposition=attachment%3B+filename%3DSensitivity_to_First_Order_Relations_of.pdf\u0026Expires=1733257089\u0026Signature=Sr5eJWK35oKIz0CdOS0C3OYFI~fnagAccY8H8G6bJ6D-cYzgvUAApQJmjNstCQIq3x0MFdTzr290sVE7GprCQFh5xhBKflMwqwXKOCgOWWHge9OZ9j58-hsIqjol6zympnyhIPh4ospshYh-vRpepcbUsJYOAO0P7GLfaaj~XUb9GkiQaCrQY8Q-ajYasSZtixZB-1WU1TWZxa1PhVdaBMR2D1ZC8e~1h~~r7uItzW2q2RQ~zTwvoucn0h2xr8Gej96cq7fx3cTr3QXUgUxc3kFL5ofJf3dl1DL9TfsGe2cgK9GVw5jPqFgcKWiFYBE5s7nTJzjnqRPP-VWVaxSxJw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

This rhythm is critical to speech perception. Some have suggested that the speech rhythm evolved de novo in humans. An alternative account -the one we explored here -is that the rhythm of speech evolved through the modification of rhythmic facial expressions. We tested this idea by investigating the structure and development of macaque monkey lipsmacks and found that their developmental trajectory is strikingly similar to the one that leads from human infant babbling to adult speech. Specifically, we show that: (1) younger monkeys produce slower, more variable mouth movements and as they get older, these movements become faster and less variable; and (2) this developmental pattern does not occur for another cyclical mouth movement -chewing. These patterns parallel human developmental patterns for speech and chewing. They suggest that, in both species, the two types of rhythmic mouth movements use different underlying neural circuits that develop in different ways. Ultimately, both lipsmacking and speech converge on a 5 Hz rhythm that represents the frequency that characterizes the speech rhythm of human adults. We conclude that monkey lipsmacking and human speech share a homologous developmental mechanism, lending strong empirical support to the idea that the human speech rhythm evolved from the rhythmic facial expressions of our primate ancestors.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Developmental Science","grobid_abstract_attachment_id":32697868},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628156/Monkey_lipsmacking_develops_like_the_human_speech_rhythm","translated_internal_url":"","created_at":"2014-01-06T22:25:12.953-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697868,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697868/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697868/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Monkey_lipsmacking_develops_like_the_hum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697868/full_text-libre.pdf?1391197643=\u0026response-content-disposition=attachment%3B+filename%3DMonkey_lipsmacking_develops_like_the_hum.pdf\u0026Expires=1733257089\u0026Signature=KzAA3ttzdOQlqr871YB0qC4F8T4MfrZkp0hScGjyxuMaHua~kgG3gv1xw-Mt54KblQgYdImoaBAt0w4QT~WFIE~n3M6iiJ6fnrOHYoAXYV6wYLFWDnYuB4-4-jWpWZ6EsEEp8cZA0u1p9fYiv-CBy49~4E35QsBTTr40Um9kDpgF52T1oIGfIuAAgXgBapycbqJSxII1XUAuBdnmauRrTxhHMoRPcv8CS5S1Ap7w3ilmNztNV7YYIIBEGLmNTbTnfrDkgOwI9MdcTn-FEJjBfjwLgz-lxJ7o6kJ9DY4v0IDTxYVqus95up2qXinNBEQ8-WkglpvbXXlLmKS4dn3Zdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Monkey_lipsmacking_develops_like_the_human_speech_rhythm","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697868,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697868/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697868/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ4OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Monkey_lipsmacking_develops_like_the_hum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697868/full_text-libre.pdf?1391197643=\u0026response-content-disposition=attachment%3B+filename%3DMonkey_lipsmacking_develops_like_the_hum.pdf\u0026Expires=1733257089\u0026Signature=KzAA3ttzdOQlqr871YB0qC4F8T4MfrZkp0hScGjyxuMaHua~kgG3gv1xw-Mt54KblQgYdImoaBAt0w4QT~WFIE~n3M6iiJ6fnrOHYoAXYV6wYLFWDnYuB4-4-jWpWZ6EsEEp8cZA0u1p9fYiv-CBy49~4E35QsBTTr40Um9kDpgF52T1oIGfIuAAgXgBapycbqJSxII1XUAuBdnmauRrTxhHMoRPcv8CS5S1Ap7w3ilmNztNV7YYIIBEGLmNTbTnfrDkgOwI9MdcTn-FEJjBfjwLgz-lxJ7o6kJ9DY4v0IDTxYVqus95up2qXinNBEQ8-WkglpvbXXlLmKS4dn3Zdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

To test whether a similar preference for female faces exists in other primates, we presented nursery-reared infant rhesus macaques with photographs of macaque faces and human faces. At \u003c1 month old, infant macaques preferentially oriented towards female macaque faces when faces were presented upright. No preference for female human faces was found. At 9 months old, infants failed to show a visual preference for female macaque faces or female human faces, although they showed significantly more lipsmacking responses at female human faces. Compared to human infants, macaques appear to have stronger predispositions early in life but this preference may nonetheless be amendable to experience. Understanding how innate predispositions and the social rearing environment shape infants' understanding of faces remain important issues to be explored in order to understand facial processing abilities in humans and other primates. ß 2009 Wiley Periodicals, Inc.

Previous studies have demonstrated some resemblance between stereotypy in captive animals and in humans, including the involvement of neurological malfunctions that lead to the expression of stereotypies. This malfunction can be evaluated through the use of neuropsychological tasks that assess perseveration as implying a failure of the basal ganglia (BG) to operate properly. Other studies, in contrast, have suggested that stereotypies are the product of neurologically intact individuals reacting to the abnormal nature of their surroundings, and are possibly characterized by an adaptive feature that enables the subject to cope with such adversity. Employing neuropsychological tests and also measuring the levels of fecal corticoids in captive rhesus macaques, we tested the hypothesis that stereotypies are related both to brain pathology and to a coping mechanism with stress, resembling accounts by autistic individuals exhibiting basal ganglia malfunction, and who report a sense of relief when performing stereotypies. Self-directed and fine-motor stereotypies exhibited by the monkeys were positively correlated with perseveration, suggesting BG malfunction; while self-directed stereotypies were also negatively correlated with an increase in fecal corticoids following a stress challenge, suggesting a related coping mechanism. We therefore suggest that not all repetitive, unvarying, and apparently functionless behaviors should be regarded as one homogeneous group of stereotypic behaviors; and that, reflecting reports from autistic individuals, self-directed stereotypies in captive rhesus monkeys are related both to brain pathology, and to an adaptive mechanism that allows those that express them to better cope with acute stressors.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Behavioral Brain Research","grobid_abstract_attachment_id":32697852},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628140/Some_stereotypic_behaviors_in_rhesus_macaques_Macaca_mulatta_are_correlated_with_both_perseveration_and_the_ability_to_cope_with_acute_stressors","translated_internal_url":"","created_at":"2014-01-06T22:22:57.872-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697852,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697852/thumbnails/1.jpg","file_name":"behavbrainres.pdf","download_url":"https://www.academia.edu/attachments/32697852/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Some_stereotypic_behaviors_in_rhesus_mac.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697852/behavbrainres-libre.pdf?1391153545=\u0026response-content-disposition=attachment%3B+filename%3DSome_stereotypic_behaviors_in_rhesus_mac.pdf\u0026Expires=1733257090\u0026Signature=IorOphwTHurJndYTZ5DD9ZXPd2GK3WbVe7huBxGIdjACJGMRYXWPPoCWMPJgTe9OcBEQ1o8zFntkNcZrbxwMLdPmMhP4h~h7spWyEp8n7Oa~YALOEg4mLeqjNNRk8L~xrVZZ2d3084IsRsIAWtGN5KM3uOMSmVxAj4ncKrm6DSRa5Uyer~zSQ3cHWo84lSE00ygh-BRWlHzZvJTndUsZOONB1v-N-AY2OBWoREVEjRmNTi8Ibo1X-Uvni4jegm6ikFUM9SaDC11P9DDD2WQz8BGEUjHs86vUTfDkDAn8mKJ8SwB455lRmkVXrBvZpza4mp-KPr318-4r~OML~xXcXA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Some_stereotypic_behaviors_in_rhesus_macaques_Macaca_mulatta_are_correlated_with_both_perseveration_and_the_ability_to_cope_with_acute_stressors","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697852,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697852/thumbnails/1.jpg","file_name":"behavbrainres.pdf","download_url":"https://www.academia.edu/attachments/32697852/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Some_stereotypic_behaviors_in_rhesus_mac.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697852/behavbrainres-libre.pdf?1391153545=\u0026response-content-disposition=attachment%3B+filename%3DSome_stereotypic_behaviors_in_rhesus_mac.pdf\u0026Expires=1733257090\u0026Signature=IorOphwTHurJndYTZ5DD9ZXPd2GK3WbVe7huBxGIdjACJGMRYXWPPoCWMPJgTe9OcBEQ1o8zFntkNcZrbxwMLdPmMhP4h~h7spWyEp8n7Oa~YALOEg4mLeqjNNRk8L~xrVZZ2d3084IsRsIAWtGN5KM3uOMSmVxAj4ncKrm6DSRa5Uyer~zSQ3cHWo84lSE00ygh-BRWlHzZvJTndUsZOONB1v-N-AY2OBWoREVEjRmNTi8Ibo1X-Uvni4jegm6ikFUM9SaDC11P9DDD2WQz8BGEUjHs86vUTfDkDAn8mKJ8SwB455lRmkVXrBvZpza4mp-KPr318-4r~OML~xXcXA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData });

However, attributing the same significance to all of these repetitive, unvarying and apparently functionless behaviours may be misleading, as some behaviours may be better indicators of stress than others. Previous studies have demonstrated that the affective state of the individual can be inferred from its bias in appraising neutral stimuli in its environment. Therefore, in the present study, in order to assess the emotional state of stereotyping individuals, 16 captive tufted capuchins (Cebus apella) were tested on a judgment bias paradigm and their faecal corticoid levels were measured in order to assess the intensity of the emotional state. Capuchins with higher levels of stereotypic head twirls exhibited a negative bias while judging ambiguous stimuli and had higher levels of faecal corticoids compared to subjects with lower levels of head twirls. Levels of stereotypic pacing, however, were not correlated with the monkeys' emotional state. This study is the first to reveal a positive correlation between levels of stereotypic behaviour and a 'pessimistic'-like judgment bias in a non-human primate by employing a recently developed cognitive approach. Combining cognitive tests that evaluate the animals' affective valence (positive or negative) with hormonal measurements that provide information on the strength of the emotional state conduces to a better understanding of the animals' affective state and therefore to their well-being.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Animal Cognition","grobid_abstract_attachment_id":32697835},"translated_abstract":null,"internal_url":"https://www.academia.edu/5628124/Stereotypic_head_twirls_but_not_pacing_are_related_to_a_pessimistic_like_judgment_bias_among_captive_tufted_capuchins_Cebus_apella_","translated_internal_url":"","created_at":"2014-01-06T22:20:07.984-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697835,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697835/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697835/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Stereotypic_head_twirls_but_not_pacing_a.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697835/full_text-libre.pdf?1391230766=\u0026response-content-disposition=attachment%3B+filename%3DStereotypic_head_twirls_but_not_pacing_a.pdf\u0026Expires=1733257090\u0026Signature=dINMvoTBjZWSFx~rsQvgcmji7kL8pslAWv-IfTW5DOXqBdSRIv8Z~FK9o5ErshE1vLCum4FYKgduXOUjE65lSjrIw1HCh7t0p3Ij~fOHblT7LOVDLjaVB089rSql0cj5TaWS~LzIWR~IWYFer1kUOQuulCYI0y7aj0WtBnJzyYj25eQN-j3pFQL6Cdmjo8WxQz1iQeAHk5F0LfZVoTME04sLf4s~SIQXkhr8Sgh~xwlS9-TyYjNixh~gudeb6GeDatxFxALzH-PS0PolJQWkaTH0Ntqjx~sZbhbI25YkMle5-Cs2XzSpdo7upXw2xIcHoqYI0ymwg8JrcYMag7yvSA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Stereotypic_head_twirls_but_not_pacing_are_related_to_a_pessimistic_like_judgment_bias_among_captive_tufted_capuchins_Cebus_apella_","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697835,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697835/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697835/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Stereotypic_head_twirls_but_not_pacing_a.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697835/full_text-libre.pdf?1391230766=\u0026response-content-disposition=attachment%3B+filename%3DStereotypic_head_twirls_but_not_pacing_a.pdf\u0026Expires=1733257090\u0026Signature=dINMvoTBjZWSFx~rsQvgcmji7kL8pslAWv-IfTW5DOXqBdSRIv8Z~FK9o5ErshE1vLCum4FYKgduXOUjE65lSjrIw1HCh7t0p3Ij~fOHblT7LOVDLjaVB089rSql0cj5TaWS~LzIWR~IWYFer1kUOQuulCYI0y7aj0WtBnJzyYj25eQN-j3pFQL6Cdmjo8WxQz1iQeAHk5F0LfZVoTME04sLf4s~SIQXkhr8Sgh~xwlS9-TyYjNixh~gudeb6GeDatxFxALzH-PS0PolJQWkaTH0Ntqjx~sZbhbI25YkMle5-Cs2XzSpdo7upXw2xIcHoqYI0ymwg8JrcYMag7yvSA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="5628106"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/5628106/Can_Traditions_Emerge_from_the_Interaction_of_Stimulus_Enhancement_and_Reinforcement_Learning_An_Experimental_Model"><img alt="Research paper thumbnail of Can Traditions Emerge from the Interaction of Stimulus Enhancement and Reinforcement Learning?

Here, we report for the first time how social group cohesion is affected by fur rubbing in tufted capuchin monkeys. Fifteen captive capuchins were each observed six times for 45 min, three times following the provision of materials typically used for fur rubbing (onion) and three times following control food items (apple). When compared with the apple condition, monkeys significantly increased proximity to one another in the first 15 min of the onion condition, which is when most fur rubbing took place. Moreover, monkeys were more likely to spend time in groups when fur rubbing but less likely to spend time in groups when manipulating the onion in other ways. In subsequent periods monkeys were less likely to be in proximity to one another in the onion condition compared with the apple condition. Aggression between group members was elevated whereas affiliation was decreased throughout the onion condition. In short, capuchins spent more time further apart and engaged in more aggressive acts and shorter affiliative acts following fur-rubbing bouts. It is possible that these differences in behavior could be owing to differences in how the monkeys competed for and interacted with the items presented in each condition rather than due to fur rubbing as such. Alternatively, fur rubbing with pungent materials might interfere with olfactory cues used to regulate social interactions within a group and thereby cause increased levels of aggression.

Humans are adept at using facial similarity to recognize likely kin, and there is evidence that nonhuman primates are also able to use facial similarity to make judgments about kinship. However, if and how nonhuman primate faces actually contain kinship information remains unclear. To test whether there is objectively measurable facial similarity in related nonhuman primates, we compared facial measurements from related (paternal half-sisters) and unrelated adult female rhesus macaques (Macaca mulatta). Facial measurements were first summarized into 5 factors using a principal component analysis. Differences in these factors between the faces of related macaques were compared with differences between the faces of random unrelated macaques and of age-matched unrelated macaques. The difference in facial measurements between related macaques was significantly smaller than the difference in facial measurements of either group of unrelated macaques, constituting an objective measure of facial similarity in macaque kin. These results indicate that kinship information is contained in the rhesus macaque face and suggest that nonhuman primates may rely in part on facial similarity to distinguish kin.","publication_date":{"day":null,"month":null,"year":2012,"errors":{}},"publication_name":"Journal of Comparative Psychology","grobid_abstract_attachment_id":32697770},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627921/Evidence_for_Kinship_Information_Contained_in_the_Rhesus_Macaque_Macaca_mulatta_Face","translated_internal_url":"","created_at":"2014-01-06T22:04:40.414-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697770,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697770/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697770/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Evidence_for_Kinship_Information_Contain.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697770/fulltext-libre.pdf?1391210088=\u0026response-content-disposition=attachment%3B+filename%3DEvidence_for_Kinship_Information_Contain.pdf\u0026Expires=1733257090\u0026Signature=ZJPQo-1qSzWMOTWq3oG5j-~HAa3KKLT~8fjWTbIPRz2HiBOg0ApiD5hID3l5Ul~HKBKbQeJRppq~gnFIhZhq1gspoELeFkJkO3WmODgszPrcXyUS9fXaPQ0j3hqgDvWqk8JcMxqBX0b05gBGxHmbPjqlgFyDUvYKKGb6Pa54Kp4QHRDgmBenBFc-tlrgvQ166puKSQ9gpT~LYDMwJM4Npl35OZtMESIjGby5iWYbzq8XposoDJ1spDZJqFoBtv6LaZa8a-w098ZRf6~t3m~eff53S~XNd-dBNG1dYvS0IYgS1uSLTiiqmR1VKn5V0xyBxzsY8VU4k5HEXAueSGvDXg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Evidence_for_Kinship_Information_Contained_in_the_Rhesus_Macaque_Macaca_mulatta_Face","translated_slug":"","page_count":6,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697770,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697770/thumbnails/1.jpg","file_name":"fulltext.pdf","download_url":"https://www.academia.edu/attachments/32697770/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Evidence_for_Kinship_Information_Contain.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697770/fulltext-libre.pdf?1391210088=\u0026response-content-disposition=attachment%3B+filename%3DEvidence_for_Kinship_Information_Contain.pdf\u0026Expires=1733257090\u0026Signature=ZJPQo-1qSzWMOTWq3oG5j-~HAa3KKLT~8fjWTbIPRz2HiBOg0ApiD5hID3l5Ul~HKBKbQeJRppq~gnFIhZhq1gspoELeFkJkO3WmODgszPrcXyUS9fXaPQ0j3hqgDvWqk8JcMxqBX0b05gBGxHmbPjqlgFyDUvYKKGb6Pa54Kp4QHRDgmBenBFc-tlrgvQ166puKSQ9gpT~LYDMwJM4Npl35OZtMESIjGby5iWYbzq8XposoDJ1spDZJqFoBtv6LaZa8a-w098ZRf6~t3m~eff53S~XNd-dBNG1dYvS0IYgS1uSLTiiqmR1VKn5V0xyBxzsY8VU4k5HEXAueSGvDXg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195994,"url":"http://dx.doi.org/10.1037/a0025081"}]}, dispatcherData: dispatcherData });

Newborn infants are also capable of exhibiting a range of facial expressions. Identification of the neural underpinnings of these capacities represents a formidable challenge in understanding social development. One possible neuronal substrate is the mirror-neuron system assumed to activate shared motor cortical representations for both observation and production of actions. We tested this hypothesis by recording scalp EEG from 1-to 7-day-old newborn rhesus macaques who were observing and producing facial gestures. We found that 5-6 Hz EEG activity was suppressed both when the infants produced facial gestures and while they were observing facial gestures of a human experimenter, but not when they were observing nonbiological stimuli. These findings demonstrate the presence of neural reactivity for biological, communicatively relevant stimuli, which may be a likely signature of neuronal mirroring. The basic elements of the mirror-neuron system appear to operate from the very first days of life and contribute to the encoding of socially relevant stimuli. ■","publication_name":"Journal of Cognitive Neuroscience","grobid_abstract_attachment_id":32697777},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627920/Distinct_EEG_Amplitude_Suppression_to_Facial_Gestures_as_Evidence_for_a_Mirror_Mechanism_in_Newborn_Monkeys","translated_internal_url":"","created_at":"2014-01-06T22:04:35.300-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697777,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697777/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697777/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Distinct_EEG_Amplitude_Suppression_to_Fa.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697777/full_text-libre.pdf?1391197175=\u0026response-content-disposition=attachment%3B+filename%3DDistinct_EEG_Amplitude_Suppression_to_Fa.pdf\u0026Expires=1733257090\u0026Signature=ATU7CoTxps8YP2nLiS29ICwkvazS-mo81JyvHJ9j~OnQUuCEEIwy3eq41iFljLBAQHEHFlnCuNBoYVxlnxI43EWD60ydV4UnM2FhQzXY82oaB4X-hLfnU00NqbGFaJbyEfmvcVzUb6~JgA~iDl-0PbLbuHDWlnsxJdc4wP47NtVNZs6BzkHo7L5s0iLZzGVb8PwDGaZSMCATFSQggY-mhRO9BzzjghfOH5yzgErOG6IW7o4LtZmwQUTDEsBizDliKOvT19X8k-D6qt-mcZUQZD7LWuTeuM89MovcuZQMJlTLril9mLjhUgXwXUzWTC7Grq4pRa7C-v00OQYPNGfdLA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Distinct_EEG_Amplitude_Suppression_to_Facial_Gestures_as_Evidence_for_a_Mirror_Mechanism_in_Newborn_Monkeys","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697777,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697777/thumbnails/1.jpg","file_name":"full_text.pdf","download_url":"https://www.academia.edu/attachments/32697777/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Distinct_EEG_Amplitude_Suppression_to_Fa.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697777/full_text-libre.pdf?1391197175=\u0026response-content-disposition=attachment%3B+filename%3DDistinct_EEG_Amplitude_Suppression_to_Fa.pdf\u0026Expires=1733257090\u0026Signature=ATU7CoTxps8YP2nLiS29ICwkvazS-mo81JyvHJ9j~OnQUuCEEIwy3eq41iFljLBAQHEHFlnCuNBoYVxlnxI43EWD60ydV4UnM2FhQzXY82oaB4X-hLfnU00NqbGFaJbyEfmvcVzUb6~JgA~iDl-0PbLbuHDWlnsxJdc4wP47NtVNZs6BzkHo7L5s0iLZzGVb8PwDGaZSMCATFSQggY-mhRO9BzzjghfOH5yzgErOG6IW7o4LtZmwQUTDEsBizDliKOvT19X8k-D6qt-mcZUQZD7LWuTeuM89MovcuZQMJlTLril9mLjhUgXwXUzWTC7Grq4pRa7C-v00OQYPNGfdLA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195993,"url":"http://dx.doi.org/10.1162/jocn_a_00198"}]}, dispatcherData: dispatcherData });

The present study investigates how different types of sensory information affect capuchins' ability to locate hidden food. In two experiments, capuchins were presented with two cups, one baited and one empty. Monkeys were given visual, acoustic, or acoustic-visual information related to the baited cup, the empty cup, or both baited and empty cup. Results show that capuchins spontaneously used visual information to locate food, and that information indicating presence and absence of food led to higher success rates than information indicating only absence of food. In contrast, acoustic information did not lead to success rates above chance levels and failed to enhance performance in combination with visual information. Capuchins spontaneously avoided a visually empty cup, but they did not appear to associate sounds with either the presence or absence of food. Being able to locate food items with the aid of acoustic cues might be a learned process that requires interactive experiences with the task's contingencies.","publication_date":{"day":null,"month":null,"year":2009,"errors":{}},"publication_name":"Journal of Comparative Psychology","grobid_abstract_attachment_id":32697795},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627917/Tufted_Capuchin_Monkeys_Cebus_apella_Spontaneously_Use_Visual_but_Not_Acoustic_Information_to_Find_Hidden_Food_Items","translated_internal_url":"","created_at":"2014-01-06T22:04:32.736-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697795,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697795/thumbnails/1.jpg","file_name":"JCP_published.pdf","download_url":"https://www.academia.edu/attachments/32697795/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697795/JCP_published-libre.pdf?1391169371=\u0026response-content-disposition=attachment%3B+filename%3DTufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf\u0026Expires=1733257090\u0026Signature=UShXrKmW4fFfksSi79Yicv6cAmYL4UAKv4r~pnYtHauECSZ2szUKjvNu8ynM2Iq5DucloiIRgBn0X-tyT-8aWXzsRYwLB3cNtjcymUvWSIaP0wWpvbaAr2irCcEskWW~zqz5IwXJ~4t5XTqzLWEHS1eApHQvSQk45GUmT~xN9zQ3O4QA0s0FvOCb7oWMu3dXLhutUvQGn5fNHS6PjVP5sxeEBuzd3NaByY8wUwdJ5AEC0z~rV072J-EPcjrtgZmv4aVKTzrbh5QZvQlM25xNWSA~q0VBZmVeP71uMH1ve4YcjVcA54YFYtqjA00oWXvErhjAEBH8EWmqLcG5Z7-wnw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Tufted_Capuchin_Monkeys_Cebus_apella_Spontaneously_Use_Visual_but_Not_Acoustic_Information_to_Find_Hidden_Food_Items","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697795,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697795/thumbnails/1.jpg","file_name":"JCP_published.pdf","download_url":"https://www.academia.edu/attachments/32697795/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697795/JCP_published-libre.pdf?1391169371=\u0026response-content-disposition=attachment%3B+filename%3DTufted_Capuchin_Monkeys_Cebus_apella_Spo.pdf\u0026Expires=1733257090\u0026Signature=UShXrKmW4fFfksSi79Yicv6cAmYL4UAKv4r~pnYtHauECSZ2szUKjvNu8ynM2Iq5DucloiIRgBn0X-tyT-8aWXzsRYwLB3cNtjcymUvWSIaP0wWpvbaAr2irCcEskWW~zqz5IwXJ~4t5XTqzLWEHS1eApHQvSQk45GUmT~xN9zQ3O4QA0s0FvOCb7oWMu3dXLhutUvQGn5fNHS6PjVP5sxeEBuzd3NaByY8wUwdJ5AEC0z~rV072J-EPcjrtgZmv4aVKTzrbh5QZvQlM25xNWSA~q0VBZmVeP71uMH1ve4YcjVcA54YFYtqjA00oWXvErhjAEBH8EWmqLcG5Z7-wnw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195990,"url":"http://dx.doi.org/10.1037/a0013128"}]}, dispatcherData: dispatcherData });

Twenty-two stumptail macaques (Macaca arctoides) were presented with video clips of either yawns or control mouth movements by conspecifics. At a group level, monkeys yawned significantly more often during and just after the yawn tape than the control tape. Supplementary analysis revealed that the yawn tape also elicited significantly more self-directed scratching responses than the control tape, which suggests that yawning might have been caused by tension arising from viewing the yawn tape. Understanding to what extent the observed effect resembles contagious yawning as found in humans and chimpanzees requires more detailed experimentation.","publication_date":{"day":null,"month":null,"year":2006,"errors":{}},"publication_name":"Biology Letters","grobid_abstract_attachment_id":32697698},"translated_abstract":null,"internal_url":"https://www.academia.edu/5627911/Video_induced_yawning_in_stumptail_macaques_Macaca_arctoides","translated_internal_url":"","created_at":"2014-01-06T22:04:27.319-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":8075042,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":32697698,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697698/thumbnails/1.jpg","file_name":"Paukner_macaca.pdf","download_url":"https://www.academia.edu/attachments/32697698/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Video_induced_yawning_in_stumptail_macaq.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697698/Paukner_macaca-libre.pdf?1391129359=\u0026response-content-disposition=attachment%3B+filename%3DVideo_induced_yawning_in_stumptail_macaq.pdf\u0026Expires=1733257090\u0026Signature=AUlHI4vA-Nc9RVH-x2TxPx0seLbTLm4xTBycYi4onmmlSrjNW1Hs57Jq4sOtDizDPJMVQm-osK7jSrOuPksJ9YiOFPDJ8HiL7FMGHdldFlFdEfXGmDbbVESU7Lsh6N4~SrS9KlWjm8Ow2V~BbBYDtcm83TGZJN9ztp5J1ESLjOXLbAL7Z2to7dLIczA43tLtQ0gFDF0Dw4yLZrWUBH2dDFexp32wTcwHzPmptjpGfOJPHhLlVf8Izgjj9LsPhDe2nq-5aLKFXl1Wes26BHJDe7F~OF8fHSHhFeyqphBKCI9mug2sO01Q-uqwsdowg8CMfyOIVdypX5GlqqxWUOIRqw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Video_induced_yawning_in_stumptail_macaques_Macaca_arctoides","translated_slug":"","page_count":3,"language":"en","content_type":"Work","owner":{"id":8075042,"first_name":"Annika","middle_initials":null,"last_name":"Paukner","page_name":"AnnikaPaukner","domain_name":"nih","created_at":"2014-01-06T22:02:29.715-08:00","display_name":"Annika Paukner","url":"https://nih.academia.edu/AnnikaPaukner"},"attachments":[{"id":32697698,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/32697698/thumbnails/1.jpg","file_name":"Paukner_macaca.pdf","download_url":"https://www.academia.edu/attachments/32697698/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Video_induced_yawning_in_stumptail_macaq.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/32697698/Paukner_macaca-libre.pdf?1391129359=\u0026response-content-disposition=attachment%3B+filename%3DVideo_induced_yawning_in_stumptail_macaq.pdf\u0026Expires=1733257090\u0026Signature=AUlHI4vA-Nc9RVH-x2TxPx0seLbTLm4xTBycYi4onmmlSrjNW1Hs57Jq4sOtDizDPJMVQm-osK7jSrOuPksJ9YiOFPDJ8HiL7FMGHdldFlFdEfXGmDbbVESU7Lsh6N4~SrS9KlWjm8Ow2V~BbBYDtcm83TGZJN9ztp5J1ESLjOXLbAL7Z2to7dLIczA43tLtQ0gFDF0Dw4yLZrWUBH2dDFexp32wTcwHzPmptjpGfOJPHhLlVf8Izgjj9LsPhDe2nq-5aLKFXl1Wes26BHJDe7F~OF8fHSHhFeyqphBKCI9mug2sO01Q-uqwsdowg8CMfyOIVdypX5GlqqxWUOIRqw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":32011,"name":"Comparative psychology","url":"https://www.academia.edu/Documents/in/Comparative_psychology"}],"urls":[{"id":2195985,"url":"http://www.baillement.com/replication/Paukner_macaca.pdf"}]}, dispatcherData: dispatcherData });

Five monkeys were presented with three tubes that could be visually searched to determine the location of a bait. The bait's visibility was experimentally manipulated, and the monkeys' spontaneous visual searches before tube selection were analyzed. In Experiment 1, three monkeys selected the baited tube significantly above chance; however, the monkeys also searched transparent tubes. In Experiment 2, a bent tube in which food was never visible was introduced. When the bent tube was baited, the monkeys failed to deduce the bait location and responded randomly.

Here we examined the effects of social experience on action-production-perception in 3-day-old rhesus macaques that were raised either with or without their biological mothers. We measured neonatal imitation skills and brain electrical activity responses while infants produced and observed facial gestures. We hypothesized that early social experiences may shape brain activity, as assessed via electroencephalogram suppression in the alpha band (5-7 Hz in infants, known as the mu rhythm) during action observation, and lead to more proficient imitation skills. Consistent with this hypothesis, infants reared by their mothers were more likely to imitate lipsmacking—a natural, affiliative gesture—and exhibited greater mu rhythm desynchronization while viewing lipsmacking gestures than nursery-reared infants. These effects were not found in response to tongue protrusion, a meaningless gesture, or a nonsocial control. These data suggest that socially enriched early experiences in the first days after birth increase brain sensitivity to socially relevant actions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b84858fc49ed60dbbb3559a5971eec0f" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":37774212,"asset_id":11575012,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/37774212/download_file?st=MTczMzI1MzQ5MCw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="11575012"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="11575012"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 11575012; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=11575012]").text(description); $(".js-view-count[data-work-id=11575012]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 11575012; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='11575012']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 11575012, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "b84858fc49ed60dbbb3559a5971eec0f" } } $('.js-work-strip[data-work-id=11575012]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":11575012,"title":"Early social experience affects neural activity to affiliative facial gestures in newborn nonhuman primates","translated_title":"","metadata":{"abstract":"A fundamental issue in cognitive neuroscience is how the brain encodes others’ actions and intentions.
