However, recently, evidence has suggested that 2-3-month-old infants are able to perceive illusory contours when motion information is available . The present study was aimed at investigating whether even newborns might perceive kinetic illusory contours when a motion easily detected by the immature newborn's visual system (i.e. stroboscopic motion) is used. In Experiment 1, using a preference looking technique, newborns' perception of kinetic illusory contours was explored using a Kanizsa figure in a static and in a kinetic display. The results showed that newborns manifest a preference for the illusory contours only in the kinetic, but not in the static, condition. In Experiment 2, using an habituation technique, newborns were habituated to a moving shape that was matched with the background in terms of random-texture-surface; thus the recovery of the shape was possible relying only on kinetic information. The results showed that infants manifested a novelty preference when presented with luminance-defined familiar and novel shapes. Altogether these findings provide evidence that motion enhances (Experiment 1) and sometimes is sufficient (Experiment 2) to induce newborns' perception of illusory contours.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/12701505" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="a1b8338289f78d0d1d90f78f9033d7a3" rel="nofollow" data-download="{"attachment_id":45997772,"asset_id":12701505,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/45997772/download_file?st=MTczOTgwNTgxNCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="31721191" href="https://independent.academia.edu/EloisaValenza">Eloisa Valenza</a><script data-card-contents-for-user="31721191" type="text/json">{"id":31721191,"first_name":"Eloisa","last_name":"Valenza","domain_name":"independent","page_name":"EloisaValenza","display_name":"Eloisa Valenza","profile_url":"https://independent.academia.edu/EloisaValenza?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_12701505 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="12701505"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 12701505, container: ".js-paper-rank-work_12701505", });

However, recently, evidence has suggested that 2-3-month-old infants are able to perceive illusory contours when motion information is available . The present study was aimed at investigating whether even newborns might perceive kinetic illusory contours when a motion easily detected by the immature newborn's visual system (i.e. stroboscopic motion) is used. In Experiment 1, using a preference looking technique, newborns' perception of kinetic illusory contours was explored using a Kanizsa figure in a static and in a kinetic display. The results showed that newborns manifest a preference for the illusory contours only in the kinetic, but not in the static, condition. In Experiment 2, using an habituation technique, newborns were habituated to a moving shape that was matched with the background in terms of random-texture-surface; thus the recovery of the shape was possible relying only on kinetic information. The results showed that infants manifested a novelty preference when presented with luminance-defined familiar and novel shapes.

What happens to the timing of the grasp movements involved in catching a ball when optical expansion information is not veridically provided? By using 2 luminescent balls of constant size and a luminescent ball that could change its diameter during flight, it was possible to manipulate the rate of optical expansion directly. The results of 2 experiments (binocular vision in Experiment l and monocular vision in Experiment 2) showed that the time of the maximal closing velocity of the hand--which conforms to the prediction if Ss use retinal expansion information--was later for the deflating ball than for the balls of constant size. Adjustments to the aperture of the hand in response to the different ball sizes, especially the adjustment of the hand to the deflating ball (even though Ss were not aware that the ball was deflating during its approach), point to a finely attuned perception-action coupling.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/29753285" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c87a70f0856d93246b421214723a6bb3" rel="nofollow" data-download="{"attachment_id":50209226,"asset_id":29753285,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50209226/download_file?st=MTczOTgwNTgxNCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="32162116" href="https://independent.academia.edu/GjpSavelsbergh">Gjp Savelsbergh</a><script data-card-contents-for-user="32162116" type="text/json">{"id":32162116,"first_name":"Gjp","last_name":"Savelsbergh","domain_name":"independent","page_name":"GjpSavelsbergh","display_name":"Gjp Savelsbergh","profile_url":"https://independent.academia.edu/GjpSavelsbergh?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_29753285 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="29753285"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 29753285, container: ".js-paper-rank-work_29753285", });

What happens to the timing of the grasp movements involved in catching a ball when optical expansion information is not veridically provided? By using 2 luminescent balls of constant size and a luminescent ball that could change its diameter during flight, it was possible to manipulate the rate of optical expansion directly. The results of 2 experiments (binocular vision in Experiment l and monocular vision in Experiment 2) showed that the time of the maximal closing velocity of the hand--which conforms to the prediction if Ss use retinal expansion information--was later for the deflating ball than for the balls of constant size. Adjustments to the aperture of the hand in response to the different ball sizes, especially the adjustment of the hand to the deflating ball (even though Ss were not aware that the ball was deflating during its approach), point to a finely attuned perception-action coupling.","downloadable_attachments":[{"id":50209226,"asset_id":29753285,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":32162116,"first_name":"Gjp","last_name":"Savelsbergh","domain_name":"independent","page_name":"GjpSavelsbergh","display_name":"Gjp Savelsbergh","profile_url":"https://independent.academia.edu/GjpSavelsbergh?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology?f_ri=13493","nofollow":true},{"id":237,"name":"Cognitive Science","url":"https://www.academia.edu/Documents/in/Cognitive_Science?f_ri=13493","nofollow":true},{"id":5614,"name":"Binocular vision","url":"https://www.academia.edu/Documents/in/Binocular_vision?f_ri=13493","nofollow":true},{"id":7736,"name":"Attention","url":"https://www.academia.edu/Documents/in/Attention?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493"},{"id":93037,"name":"Orientation","url":"https://www.academia.edu/Documents/in/Orientation?f_ri=13493"},{"id":119665,"name":"Reaction Time","url":"https://www.academia.edu/Documents/in/Reaction_Time?f_ri=13493"},{"id":124303,"name":"Size Perception","url":"https://www.academia.edu/Documents/in/Size_Perception?f_ri=13493"},{"id":198544,"name":"Direct manipulation","url":"https://www.academia.edu/Documents/in/Direct_manipulation?f_ri=13493"},{"id":329844,"name":"Experimental","url":"https://www.academia.edu/Documents/in/Experimental?f_ri=13493"},{"id":626453,"name":"Monocular Vision","url":"https://www.academia.edu/Documents/in/Monocular_Vision?f_ri=13493"},{"id":2444775,"name":"Psychomotor Performance","url":"https://www.academia.edu/Documents/in/Psychomotor_Performance?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_79742758" data-work_id="79742758" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/79742758/Is_automatic_imitation_a_specialized_form_of_stimulus_response_compatibility_Dissociating_imitative_and_spatial_compatibilities">Is automatic imitation a specialized form of stimulus–response compatibility?

These simulations involve the re-activation of patterns of brain activation that were formed during the comprehender's interaction with the world. In two experiments we explored the specificity of the processing mechanisms required to construct simulations during language comprehension. Participants listened to (and made judgments on) sentences that described motion in a particular direction (e.g. "The car approached you"). They simultaneously viewed dynamic black-and-white stimuli that produced the perception of movement in the same direction as the action specified in the sentence (i.e. towards you) or in the opposite direction as the action specified in the sentence (i.e. away from you). Responses were faster to sentences presented concurrently with a visual stimulus depicting motion in the opposite direction as the action described in the sentence. This suggests that the processing mechanisms recruited to construct simulations during language comprehension are also used during visual perception, and that these mechanisms can be quite specific. q</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/4983054" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3a135d13204261f030ef412b6c4cf49e" rel="nofollow" data-download="{"attachment_id":49500839,"asset_id":4983054,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/49500839/download_file?st=MTczOTgwNTgxNCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="6586875" href="https://independent.academia.edu/DavidTherriault">David Therriault</a><script data-card-contents-for-user="6586875" type="text/json">{"id":6586875,"first_name":"David","last_name":"Therriault","domain_name":"independent","page_name":"DavidTherriault","display_name":"David Therriault","profile_url":"https://independent.academia.edu/DavidTherriault?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_4983054 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="4983054"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 4983054, container: ".js-paper-rank-work_4983054", });

Twenty visually normal drivers (mean age = 40.3 years) participated in an experiment conducted at two open-road work sites (one suburban and one freeway) at nighttime. At each site, four road workers walked in place wearing a standard road worker night vest either a) alone, b) with additional retroreflective strips on thighs, c) with additional retroreflective strips on ankles and knees, or d) with additional retroreflective strips on eight moveable joints (full biomotion). Participants, seated in stationary vehicles at three different distances (80 m, 160 m, 240 m), rated the relative conspicuity of the four road workers. Road worker conspicuity was maximized by the full biomotion configuration at all distances and at both sites. The addition of ankle and knee markings also provided significant benefits relative to the standard vest alone. The effects of clothing configuration were more evident at the freeway site and at shorter distances. Overall, the full biomotion configuration was ranked to be most conspicuous and the vest least conspicuous. These data provide the first evidence that biomotion effectively enhances conspicuity of road workers at open-road work sites.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/11915398" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="949b345881285ea314b8f936a068240c" rel="nofollow" data-download="{"attachment_id":46439683,"asset_id":11915398,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46439683/download_file?st=MTczOTgwNTgxNCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="29493679" href="https://independent.academia.edu/ralphmarszalek">ralph marszalek</a><script data-card-contents-for-user="29493679" type="text/json">{"id":29493679,"first_name":"ralph","last_name":"marszalek","domain_name":"independent","page_name":"ralphmarszalek","display_name":"ralph marszalek","profile_url":"https://independent.academia.edu/ralphmarszalek?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_11915398 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="11915398"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 11915398, container: ".js-paper-rank-work_11915398", });

Twenty visually normal drivers (mean age = 40.3 years) participated in an experiment conducted at two open-road work sites (one suburban and one freeway) at nighttime. At each site, four road workers walked in place wearing a standard road worker night vest either a) alone, b) with additional retroreflective strips on thighs, c) with additional retroreflective strips on ankles and knees, or d) with additional retroreflective strips on eight moveable joints (full biomotion). Participants, seated in stationary vehicles at three different distances (80 m, 160 m, 240 m), rated the relative conspicuity of the four road workers. Road worker conspicuity was maximized by the full biomotion configuration at all distances and at both sites. The addition of ankle and knee markings also provided significant benefits relative to the standard vest alone. The effects of clothing configuration were more evident at the freeway site and at shorter distances. Overall, the full biomotion configuration was ranked to be most conspicuous and the vest least conspicuous. These data provide the first evidence that biomotion effectively enhances conspicuity of road workers at open-road work sites.","downloadable_attachments":[{"id":46439683,"asset_id":11915398,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":29493679,"first_name":"ralph","last_name":"marszalek","domain_name":"independent","page_name":"ralphmarszalek","display_name":"ralph marszalek","profile_url":"https://independent.academia.edu/ralphmarszalek?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology?f_ri=13493","nofollow":true},{"id":5359,"name":"Visual perception","url":"https://www.academia.edu/Documents/in/Visual_perception?f_ri=13493","nofollow":true},{"id":7736,"name":"Attention","url":"https://www.academia.edu/Documents/in/Attention?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true},{"id":66843,"name":"Judgment","url":"https://www.academia.edu/Documents/in/Judgment?f_ri=13493"},{"id":68567,"name":"Queensland","url":"https://www.academia.edu/Documents/in/Queensland?f_ri=13493"},{"id":86644,"name":"Darkness","url":"https://www.academia.edu/Documents/in/Darkness?f_ri=13493"},{"id":101839,"name":"Lighting","url":"https://www.academia.edu/Documents/in/Lighting?f_ri=13493"},{"id":124302,"name":"Distance Perception","url":"https://www.academia.edu/Documents/in/Distance_Perception?f_ri=13493"},{"id":133057,"name":"Young Adult","url":"https://www.academia.edu/Documents/in/Young_Adult?f_ri=13493"},{"id":144029,"name":"Biological Motion","url":"https://www.academia.edu/Documents/in/Biological_Motion?f_ri=13493"},{"id":159978,"name":"Visibility","url":"https://www.academia.edu/Documents/in/Visibility?f_ri=13493"},{"id":289271,"name":"Aged","url":"https://www.academia.edu/Documents/in/Aged?f_ri=13493"},{"id":399641,"name":"Accident analysis and prevention","url":"https://www.academia.edu/Documents/in/Accident_analysis_and_prevention?f_ri=13493"},{"id":410370,"name":"Public health systems and services research","url":"https://www.academia.edu/Documents/in/Public_health_systems_and_services_research-1?f_ri=13493"},{"id":535415,"name":"Environment Design","url":"https://www.academia.edu/Documents/in/Environment_Design?f_ri=13493"},{"id":650731,"name":"Accident analysis","url":"https://www.academia.edu/Documents/in/Accident_analysis?f_ri=13493"},{"id":1450093,"name":"Protective Clothing","url":"https://www.academia.edu/Documents/in/Protective_Clothing?f_ri=13493"},{"id":2248971,"name":"Automobile driving","url":"https://www.academia.edu/Documents/in/Automobile_driving?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_36967839" data-work_id="36967839" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/36967839/Effects_of_immersion_in_virtual_reality_on_postural_control">Effects of immersion in virtual reality on postural control</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">In the present study, we examined the effects of the time lag between visual scene and the head movement in the virtual reality (VR) world on motion sickness and postural control in healthy volunteers.

After immersion in VR with additional time lags (from 0 to 0.8 s) to the inherent delay (about 250 ms), the visual-vestibular conflict induced a slight motion sickness in experimental subjects, but no change was noticed in the body sway path with eyes open and closed. However, Romberg ratio of body sway path with eyes closed divided by that with eyes open after immersion in VR was significantly decreased in comparison with that before immersion in VR. Since Romberg ratio is an index of visual dependency on postural control, this finding indicates that the immersion in VR decreases the visual dependency on postural control. It is suggested that adaptation to visual-vestibular conflict in VR immersion increases the contribution of vestibular and somatosensory inputs to postural control by ignoring the conflicting delayed visual input in the VR world. VR may be a promising treatment for visual vertigo in vestibular patients with unsuccessful compensation by its ability to induce vestibular and somatosensory reweighing for postural control.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/36967839" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4b30e02882eebbdad0b90da577b23257" rel="nofollow" data-download="{"attachment_id":56917510,"asset_id":36967839,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/56917510/download_file?st=MTczOTgwNTgxNCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="84663278" href="https://independent.academia.edu/AtsuhikoUno">Atsuhiko Uno</a><script data-card-contents-for-user="84663278" type="text/json">{"id":84663278,"first_name":"Atsuhiko","last_name":"Uno","domain_name":"independent","page_name":"AtsuhikoUno","display_name":"Atsuhiko Uno","profile_url":"https://independent.academia.edu/AtsuhikoUno?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_36967839 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="36967839"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 36967839, container: ".js-paper-rank-work_36967839", });

Judgments about 3-D shape from motion involve both parietal and occipito-temporal regions.

Subjects made judgments about several different attributes of these objects, including 3-D shape, the 3-D motion, and the scale of surface texture. For all of these tasks, we equated visual input, motor output, and task difficulty, and we controlled for differ-ences in spatial attention. Judgments about 3-D shape from motion involve both parietal and occipito-temporal regions. The processing of 3-D shape is associated with the analysis of 3-D motion in parietal regions and the analysis of surface texture in occipito-temporal regions, which is consistent with the different behavioral roles that are typically attributed to the dorsal and ventral processing streams. \u0026","downloadable_attachments":[{"id":43214522,"asset_id":22615868,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":27681192,"first_name":"Hendrik","last_name":"Peuskens","domain_name":"kuleuven","page_name":"HendrikPeuskens","display_name":"Hendrik Peuskens","profile_url":"https://kuleuven.academia.edu/HendrikPeuskens?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology?f_ri=13493","nofollow":true},{"id":237,"name":"Cognitive Science","url":"https://www.academia.edu/Documents/in/Cognitive_Science?f_ri=13493","nofollow":true},{"id":6200,"name":"Magnetic Resonance Imaging","url":"https://www.academia.edu/Documents/in/Magnetic_Resonance_Imaging?f_ri=13493","nofollow":true},{"id":7736,"name":"Attention","url":"https://www.academia.edu/Documents/in/Attention?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493"},{"id":21548,"name":"Cognitive Neuroscience","url":"https://www.academia.edu/Documents/in/Cognitive_Neuroscience?f_ri=13493"},{"id":35888,"name":"Cognitive","url":"https://www.academia.edu/Documents/in/Cognitive?f_ri=13493"},{"id":41031,"name":"Structure from Motion","url":"https://www.academia.edu/Documents/in/Structure_from_Motion?f_ri=13493"},{"id":56633,"name":"Spatial Attention","url":"https://www.academia.edu/Documents/in/Spatial_Attention?f_ri=13493"},{"id":57557,"name":"Temporal Lobe","url":"https://www.academia.edu/Documents/in/Temporal_Lobe?f_ri=13493"},{"id":82283,"name":"Form perception","url":"https://www.academia.edu/Documents/in/Form_perception?f_ri=13493"},{"id":124863,"name":"Motion processing","url":"https://www.academia.edu/Documents/in/Motion_processing?f_ri=13493"},{"id":207295,"name":"Task Difficulty","url":"https://www.academia.edu/Documents/in/Task_Difficulty?f_ri=13493"},{"id":406036,"name":"Parietal Lobe","url":"https://www.academia.edu/Documents/in/Parietal_Lobe?f_ri=13493"},{"id":504035,"name":"Three Dimensional","url":"https://www.academia.edu/Documents/in/Three_Dimensional?f_ri=13493"},{"id":818658,"name":"Rotation","url":"https://www.academia.edu/Documents/in/Rotation?f_ri=13493"},{"id":1239755,"name":"Neurosciences","url":"https://www.academia.edu/Documents/in/Neurosciences?f_ri=13493"},{"id":1749681,"name":"Surface Texture","url":"https://www.academia.edu/Documents/in/Surface_Texture?f_ri=13493"},{"id":1766624,"name":"Occipital Lobe","url":"https://www.academia.edu/Documents/in/Occipital_Lobe?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_56817549" data-work_id="56817549" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/56817549/The_parallel_visual_motion_inputs_into_areas_V1_and_V5_of_human_cerebral_cortex">The parallel visual motion inputs into areas V1 and V5 of human cerebral cortex</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Published clinical evidence has led us to hypothesize that there are parallel pathways which lead to the striate (VI) and prestriate cortex in the human brain.

However, it is unclear whether these detectors are tuned to specific 'cardinal directions' (such as radial and circular motion), or whether they respond equally to all directions of optic-flow motion, including intermediate spiral motions. Here summation and masking studies of motion coherence sensitivity are reported that suggest that optic flow may be tuned to radial and circular cardinal directions. Strong summation was found between two orthogonal directions of spiral motion, but much weaker summation between radial and circular motion. As orthogonal spiral motions always contain a common radial or circular component, the stronger summation for these motions implies that detectors are tuned to radial and circular directions. Similarly, the most effective masking stimuli (placed adjacent to but not superimposed on the test stimuli) tended to be those in the radial or circular directions, even for spiral targets, further suggesting that flow-field motion is detected and discriminated by mechanisms tuned to these 'cardinal' directions.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/18360799" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="1ac8c0be68aaa9d69951c12a4137809b" rel="nofollow" data-download="{"attachment_id":40013327,"asset_id":18360799,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/40013327/download_file?st=MTczOTgwNTgxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="38349877" href="https://independent.academia.edu/DavidBadcock">David Badcock</a><script data-card-contents-for-user="38349877" type="text/json">{"id":38349877,"first_name":"David","last_name":"Badcock","domain_name":"independent","page_name":"DavidBadcock","display_name":"David Badcock","profile_url":"https://independent.academia.edu/DavidBadcock?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_18360799 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="18360799"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 18360799, container: ".js-paper-rank-work_18360799", });

This study investigated the differential stability of the 2 phase modes. In Experiment 1, in which Ss were instructed to remain in the initial phase mode, the alternate phase mode was found to be less stable as the frequency of oscillation increased. In addition, analysis of the nonsteady state cycles revealed evidence of a switching to the symmetric phase mode for the initial alternate phase mode trials. In Experiments 2 and 3, Ss were instructed to remain at a noninitial phase angle if it was found to be more comfortable. The transition observed between the 2 phase modes satisfies the criteria of a physical bifurcation--hysteresis, critical fluctuations, and divergence--and is consonant with previous findings on transitions in limb coordination within a person.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/15148027" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="57dcb1340ae64435458a090616cdc3bb" rel="nofollow" data-download="{"attachment_id":43530804,"asset_id":15148027,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/43530804/download_file?st=MTczOTgwNTgxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="34187376" href="https://independent.academia.edu/ClaudiaCarello">Claudia Carello</a><script data-card-contents-for-user="34187376" type="text/json">{"id":34187376,"first_name":"Claudia","last_name":"Carello","domain_name":"independent","page_name":"ClaudiaCarello","display_name":"Claudia Carello","profile_url":"https://independent.academia.edu/ClaudiaCarello?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_15148027 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="15148027"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 15148027, container: ".js-paper-rank-work_15148027", });

In Experiment 1, in which Ss were instructed to remain in the initial phase mode, the alternate phase mode was found to be less stable as the frequency of oscillation increased. In addition, analysis of the nonsteady state cycles revealed evidence of a switching to the symmetric phase mode for the initial alternate phase mode trials. In Experiments 2 and 3, Ss were instructed to remain at a noninitial phase angle if it was found to be more comfortable. The transition observed between the 2 phase modes satisfies the criteria of a physical bifurcation--hysteresis, critical fluctuations, and divergence--and is consonant with previous findings on transitions in limb coordination within a person.","downloadable_attachments":[{"id":43530804,"asset_id":15148027,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":34187376,"first_name":"Claudia","last_name":"Carello","domain_name":"independent","page_name":"ClaudiaCarello","display_name":"Claudia Carello","profile_url":"https://independent.academia.edu/ClaudiaCarello?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology?f_ri=13493","nofollow":true},{"id":237,"name":"Cognitive Science","url":"https://www.academia.edu/Documents/in/Cognitive_Science?f_ri=13493","nofollow":true},{"id":5359,"name":"Visual perception","url":"https://www.academia.edu/Documents/in/Visual_perception?f_ri=13493","nofollow":true},{"id":7736,"name":"Attention","url":"https://www.academia.edu/Documents/in/Attention?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493"},{"id":21902,"name":"Time Perception","url":"https://www.academia.edu/Documents/in/Time_Perception?f_ri=13493"},{"id":99089,"name":"Motor","url":"https://www.academia.edu/Documents/in/Motor?f_ri=13493"},{"id":172809,"name":"Interpersonal Relations","url":"https://www.academia.edu/Documents/in/Interpersonal_Relations?f_ri=13493"},{"id":173963,"name":"Phase transition","url":"https://www.academia.edu/Documents/in/Phase_transition?f_ri=13493"},{"id":174781,"name":"Oscillations","url":"https://www.academia.edu/Documents/in/Oscillations?f_ri=13493"},{"id":329844,"name":"Experimental","url":"https://www.academia.edu/Documents/in/Experimental?f_ri=13493"},{"id":679783,"name":"Boolean Satisfiability","url":"https://www.academia.edu/Documents/in/Boolean_Satisfiability?f_ri=13493"},{"id":843237,"name":"Dynamic Stability","url":"https://www.academia.edu/Documents/in/Dynamic_Stability?f_ri=13493"},{"id":1243516,"name":"Spatial Dependence","url":"https://www.academia.edu/Documents/in/Spatial_Dependence?f_ri=13493"},{"id":1291623,"name":"Motor Behavior","url":"https://www.academia.edu/Documents/in/Motor_Behavior?f_ri=13493"},{"id":2047732,"name":"Movement pattern","url":"https://www.academia.edu/Documents/in/Movement_pattern?f_ri=13493"},{"id":2246318,"name":"Motor activity","url":"https://www.academia.edu/Documents/in/Motor_activity?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_19184623" data-work_id="19184623" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/19184623/The_development_of_two_dimensional_tracking_a_longitudinal_study_of_circular_pursuit">The development of two-dimensional tracking: a longitudinal study of circular pursuit</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">We investigated 6-to 12-month-old infants' ability to track an object moving on circular trajectories, using a longitudinal design.

Finally, the authors present a descriptive model that may go some way toward explaining the reasons for the differences in collected data outlined in this article.","downloadable_attachments":[{"id":4909536,"asset_id":819917,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":656154,"first_name":"Simon","last_name":"Cropper","domain_name":"unimelb","page_name":"SimonCropper","display_name":"Simon Cropper","profile_url":"https://unimelb.academia.edu/SimonCropper?f_ri=13493","photo":"https://0.academia-photos.com/656154/227665/266336/s65_simon.cropper.jpg"}],"research_interests":[{"id":2493,"name":"Colour Vision","url":"https://www.academia.edu/Documents/in/Colour_Vision?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_69355955" data-work_id="69355955" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/69355955/A_Principal_Component_Regression_Strategy_for_Estimating_Motion">A Principal Component Regression Strategy for Estimating Motion</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">In this paper, we derive a principal component regression (PCR) method for estimating the optical flow between frames of video sequences according to a pel-recursive manner.

This study examines the effect of a VR environment on kinetic gait parameters. Ten healthy volunteers walked on an instrumented treadmill in a VR environment and a non-VR environment. In the VR environment, a corridor with colored vertical stripes comprising the walls was projected onto a concave screen placed in front of the treadmill. The speed of the moving image was perceptually equivalent to the speed of the treadmill, creating an illusion that subjects walked through the corridor. Vertical ground reaction forces were sampled. Kinetic parameters that reflect gait stability (weight acceptance peak force, weight acceptance rate, push-off peak force and push-off rate) were compared between the VR and non-VR environments.

V5 represents an important substrate for visual motion processing. Neurons in this area show a sharp preference for direction and speed of visual stimuli. Neuronal activity correlates with the ability to detect and discriminate motion in several psychophysical paradigms. The nature of neuronal representation of motion in V5 is much debated currently.

Neuronal activity correlates with the ability to detect and discriminate motion in several psychophysical paradigms. The nature of neuronal representation of motion in V5 is much debated currently. The following article provides a summary of basic anatomical, neurophysiological, neuropsychological, and behavioural data related to the role of area V5 in the processing of visual motion information.","downloadable_attachments":[{"id":54207086,"asset_id":34304404,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":39755722,"first_name":"Igor","last_name":"Riecansky","domain_name":"sav-sk","page_name":"IgorRiecansky","display_name":"Igor Riecansky","profile_url":"https://sav-sk.academia.edu/IgorRiecansky?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":5359,"name":"Visual perception","url":"https://www.academia.edu/Documents/in/Visual_perception?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true},{"id":49962,"name":"Visual Cortex","url":"https://www.academia.edu/Documents/in/Visual_Cortex?f_ri=13493","nofollow":true},{"id":57557,"name":"Temporal Lobe","url":"https://www.academia.edu/Documents/in/Temporal_Lobe?f_ri=13493","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_17590999 coauthored" data-work_id="17590999" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/17590999/Functional_declines_as_predictors_of_risky_street_crossing_decisions_in_older_pedestrians">Functional declines as predictors of risky street-crossing decisions in older pedestrians</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The experiment investigated the extent to which risky street-crossing decisions by older pedestrians can be explained by declines in functional abilities.

Sixteen young (age 20-35), 17 younger-old (age 60-67), and 18 older-old (age 70-84) participants carried out a street-crossing task in a simulated two-way road environment and took a battery of tests assessing perceptual, cognitive, and motor abilities. Older-old pedestrians were more likely than young and younger-old participants to make decisions that would have led to collisions with approaching cars, especially when traffic coming from two directions was approaching at a high speed. Regression analyses identified several functional performance measures as predictors of these dangerous choices. Walking speed, which determined the time needed to cross, was shown to play the most important role. Time-to-arrival estimate, which informed the pedestrians about the time available for crossing, was found to be the second most predictive factor. Visual processing speed and visual attention abilities assessed via the UFOV ® Test also came into play, allowing participants to focus their attention on the relevant available information and to make timely, correct decisions. Attention shifting was the fourth significant predictor, allowing pedestrians to adapt their crossing strategy to the oncoming road-traffic information. The results suggest that the greater risk of being involved in a collision as age increases calls for a multi-dimensional explanation combining age-related physical, perceptual, and cognitive performance declines. These findings have implications for improving older pedestrians' safety in terms of speed limits, road design, and training.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/17590999" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4dadeb26c3ce986c1d1ac233aac51ceb" rel="nofollow" data-download="{"attachment_id":42011835,"asset_id":17590999,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/42011835/download_file?st=MTczOTgwNTgxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="37532782" href="https://independent.academia.edu/ViolaCavallo">Viola Cavallo</a><script data-card-contents-for-user="37532782" type="text/json">{"id":37532782,"first_name":"Viola","last_name":"Cavallo","domain_name":"independent","page_name":"ViolaCavallo","display_name":"Viola Cavallo","profile_url":"https://independent.academia.edu/ViolaCavallo?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-17590999">+1</span><div class="hidden js-additional-users-17590999"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/JenniferOxley">Jennifer Oxley</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-17590999'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-17590999').html();

The risk is exacerbated because vehicles moving faster than this speed are more likely to result in pedestrian fatalities.","downloadable_attachments":[{"id":51135838,"asset_id":1003785,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":266738,"first_name":"Catherine","last_name":"Purcell","domain_name":"royalholloway","page_name":"CatherinePurcell","display_name":"Catherine Purcell","profile_url":"https://royalholloway.academia.edu/CatherinePurcell?f_ri=13493","photo":"https://0.academia-photos.com/266738/65568/168199/s65_catherine.purcell.jpg"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology?f_ri=13493","nofollow":true},{"id":237,"name":"Cognitive Science","url":"https://www.academia.edu/Documents/in/Cognitive_Science?f_ri=13493","nofollow":true},{"id":867,"name":"Perception","url":"https://www.academia.edu/Documents/in/Perception?f_ri=13493","nofollow":true},{"id":5359,"name":"Visual perception","url":"https://www.academia.edu/Documents/in/Visual_perception?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493"},{"id":13590,"name":"Risk Taking","url":"https://www.academia.edu/Documents/in/Risk_Taking?f_ri=13493"},{"id":45666,"name":"Automobiles","url":"https://www.academia.edu/Documents/in/Automobiles?f_ri=13493"},{"id":49161,"name":"Safety","url":"https://www.academia.edu/Documents/in/Safety?f_ri=13493"},{"id":59692,"name":"Vision","url":"https://www.academia.edu/Documents/in/Vision?f_ri=13493"},{"id":64933,"name":"Child","url":"https://www.academia.edu/Documents/in/Child?f_ri=13493"},{"id":69542,"name":"Computer Simulation","url":"https://www.academia.edu/Documents/in/Computer_Simulation?f_ri=13493"},{"id":116271,"name":"Child Psychology","url":"https://www.academia.edu/Documents/in/Child_Psychology?f_ri=13493"},{"id":337500,"name":"Velocity","url":"https://www.academia.edu/Documents/in/Velocity?f_ri=13493"},{"id":401947,"name":"Sensitivity","url":"https://www.academia.edu/Documents/in/Sensitivity?f_ri=13493"},{"id":546419,"name":"Age Factors","url":"https://www.academia.edu/Documents/in/Age_Factors?f_ri=13493"},{"id":743604,"name":"Psychological Science","url":"https://www.academia.edu/Documents/in/Psychological_Science?f_ri=13493"},{"id":1832927,"name":"Looming","url":"https://www.academia.edu/Documents/in/Looming?f_ri=13493"},{"id":1929419,"name":"Nino","url":"https://www.academia.edu/Documents/in/Nino?f_ri=13493"},{"id":2248971,"name":"Automobile driving","url":"https://www.academia.edu/Documents/in/Automobile_driving?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_3288033" data-work_id="3288033" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/3288033/The_waterfall_illusion_in_an_insect_visual_system">The waterfall illusion in an insect visual system</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The waterfall illusion, or movement after-effect, is a well-known visual illusion wherein prolonged exposure to a pattern moving in a given direction causes a subsequently-presented, stationary pattern to appear to move in the opposite... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_3288033" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">The waterfall illusion, or movement after-effect, is a well-known visual illusion wherein prolonged exposure to a pattern moving in a given direction causes a subsequently-presented, stationary pattern to appear to move in the opposite direction (see, for example, Cornsweet, 1970).

Motion stimuli consisted of single cycles of sinusoidal acceleration and were generated by a motion platform. An adaptive two-alternative categorical forced-choice procedure was used. The subjects had to indicate by button presses whether they perceived yaw rotation to the left or to the right. Thresholds were measured using a 3-down, 1-up staircase paradigm. Mean yaw rotation velocity thresholds were 2.8 deg s−1 for 0.05 Hz, 2.5 deg s−1 for 0.1 Hz, 1.7 deg s−1 for 0.2 Hz, 0.7 deg s−1 for 0.5 Hz, 0.6 deg s−1 for 1 Hz, 0.4 deg s−1 for 2 Hz, and 0.6 deg s−1 for 5 Hz. The results show that motion thresholds increase at 0.2 Hz and below and plateau at 0.5 Hz and above. Increasing velocity thresholds at lower frequencies qualitatively mimic the high-pass characteristics of the semicircular canals, since the increase at 0.2 Hz and below would be consistent with decreased gain/sensitivity observed in the VOR at lower frequencies. In fact, the measured dynamics are consistent with a high pass filter having a threshold plateau of 0.71 deg s-1 and a cut-off frequency of 0.23 Hz, which corresponds to a time constant of approximately 0.70 s. These findings provide no evidence for an influence of velocity storage on perceptual yaw rotation thresholds.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/5907091" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="42c62e7f33e328048b6c5476a05b6d1e" rel="nofollow" data-download="{"attachment_id":49093920,"asset_id":5907091,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/49093920/download_file?st=MTczOTgwNTgxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="670227" href="https://unibe-ch.academia.edu/FredMast">Fred W Mast</a><script data-card-contents-for-user="670227" type="text/json">{"id":670227,"first_name":"Fred","last_name":"Mast","domain_name":"unibe-ch","page_name":"FredMast","display_name":"Fred W Mast","profile_url":"https://unibe-ch.academia.edu/FredMast?f_ri=13493","photo":"https://0.academia-photos.com/670227/2897276/12466652/s65_fred.mast.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-5907091">+1</span><div class="hidden js-additional-users-5907091"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://unisa-au.academia.edu/LuziaGrabherr">Luzia Grabherr</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-5907091'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-5907091').html();

These findings provide no evidence for an influence of velocity storage on perceptual yaw rotation thresholds.","downloadable_attachments":[{"id":49093920,"asset_id":5907091,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":670227,"first_name":"Fred","last_name":"Mast","domain_name":"unibe-ch","page_name":"FredMast","display_name":"Fred W Mast","profile_url":"https://unibe-ch.academia.edu/FredMast?f_ri=13493","photo":"https://0.academia-photos.com/670227/2897276/12466652/s65_fred.mast.jpg"},{"id":2156066,"first_name":"Luzia","last_name":"Grabherr","domain_name":"unisa-au","page_name":"LuziaGrabherr","display_name":"Luzia Grabherr","profile_url":"https://unisa-au.academia.edu/LuziaGrabherr?f_ri=13493","photo":"https://0.academia-photos.com/2156066/696757/4718613/s65_luzia.grabherr.jpg"}],"research_interests":[{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true},{"id":358198,"name":"Constant Time Delay","url":"https://www.academia.edu/Documents/in/Constant_Time_Delay?f_ri=13493","nofollow":true},{"id":818658,"name":"Rotation","url":"https://www.academia.edu/Documents/in/Rotation?f_ri=13493","nofollow":true},{"id":1529835,"name":"Choice Behavior","url":"https://www.academia.edu/Documents/in/Choice_Behavior?f_ri=13493","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_65810832" data-work_id="65810832" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/65810832/Perception_of_linear_horizontal_self_motion_induced_by_peripheral_vision_linearvection_basic_characteristics_and_visual_vestibular_interactions">Perception of linear horizontal self-motion induced by peripheral vision (linearvection) basic characteristics and visual-vestibular interactions</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The basic characteristics of the sensation of linear horizontal motion have been studied.

This aftereffect can be obtained for a specific range of adaptation speeds with its magnitude generally peaking for speeds around 3 deg s -1 . The classic motion aftereffect is usually measured with a static test pattern. Here, we measured the magnitude of the motion aftereffect for a large range of velocities covering also higher speeds, using both static and dynamic test patterns. The results suggest that at least two (sub)populations of motion-sensitive neurons underlie these motion aftereffects. One population shows itself under static test conditions and is dominant for low adaptation speeds, and the other is prevalent under dynamic test conditions after adaptation to high speeds. The dynamic motion aftereffect can be perceived for adaptation speeds up to three times as fast as the static motion aftereffect. We tested predictions that follow from the hypothesised division in neuronal substrates. We found that for exactly the same adaptation conditions (oppositely directed transparent motion with different speeds), the aftereffect direction differs by 180° depending on the test pattern. The motion aftereffect is opposite to the pattern moving at low speed when the test pattern is static, and opposite to the high-speed pattern for a dynamic test pattern. The determining factor is the combination of adaptation speed and type of test pattern.

Fourteen volunteers performed isometric actions in two conditions: (i) a static tracking task consisting of flexion/pronation, ulnar deviation, extension/supination and radial deviation of the wrist at 20% maximum voluntary contraction (MVC), and (ii) a dynamic tracking task aiming at following a moving target at 20% MVC in the four directions of contraction. Surface electromyography (SEMG) from extensor carpi ulnaris, extensor carpi radialis, flexor carpi ulnaris and flexor digitorum superficialis muscles and exerted forces in the transverse and sagittal plane were recorded. Normalized root mean square and mutual information (index of functional connectivity within muscles) of SEMGs and the standard deviation and sample entropy of force signals were extracted. Larger SEMG amplitudes were found for the dynamic task (p&amp;amp;amp;lt;.05), while normalized mutual information between muscle pairs was larger for the static task (p&amp;amp;amp;lt;.05). Larger size of variability (standard deviation of force) concomitant with smaller sample entropy was observed for the dynamic task compared with the static task (p&amp;amp;amp;lt;.01 for both).

The task was to indicate the direction of motion in one of the modalities, called the target modality, that could be congruent or incongruent with the direction of the second motion stream, called the distractor modality.","downloadable_attachments":[{"id":44147328,"asset_id":14438824,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":33376713,"first_name":"Scott","last_name":"Sinnett","domain_name":"manoa-hawaii","page_name":"ScottSinnett","display_name":"Scott Sinnett","profile_url":"https://manoa-hawaii.academia.edu/ScottSinnett?f_ri=13493","photo":"/images/s65_no_pic.png"},{"id":33442502,"first_name":"Ipek","last_name":"Oruç","domain_name":"ubc","page_name":"IpekOruç","display_name":"Ipek Oruç","profile_url":"https://ubc.academia.edu/IpekOru%C3%A7?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":237,"name":"Cognitive Science","url":"https://www.academia.edu/Documents/in/Cognitive_Science?f_ri=13493","nofollow":true},{"id":3031,"name":"Auditory Perception","url":"https://www.academia.edu/Documents/in/Auditory_Perception?f_ri=13493","nofollow":true},{"id":7736,"name":"Attention","url":"https://www.academia.edu/Documents/in/Attention?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true},{"id":61474,"name":"Brain","url":"https://www.academia.edu/Documents/in/Brain?f_ri=13493"},{"id":80523,"name":"Multisensory Integration","url":"https://www.academia.edu/Documents/in/Multisensory_Integration?f_ri=13493"},{"id":119665,"name":"Reaction Time","url":"https://www.academia.edu/Documents/in/Reaction_Time?f_ri=13493"},{"id":155836,"name":"Audio Visual","url":"https://www.academia.edu/Documents/in/Audio_Visual?f_ri=13493"},{"id":186883,"name":"Apparent Motion","url":"https://www.academia.edu/Documents/in/Apparent_Motion?f_ri=13493"},{"id":467619,"name":"Touch Perception","url":"https://www.academia.edu/Documents/in/Touch_Perception?f_ri=13493"},{"id":1239755,"name":"Neurosciences","url":"https://www.academia.edu/Documents/in/Neurosciences?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_2483301" data-work_id="2483301" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/2483301/Receptive_fields_and_functional_architecture_in_two_nonstriate_visual_areas_18_and_19_of_the_cat">Receptive fields and functional architecture in two nonstriate visual areas (18 and 19) of the cat</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Functional architecture of the striate cortex is known mostly at the tissue level -how neurons of different function distribute across its depth and surface on a scale of millimetres.

Functional architecture of the retina is known from the scale of millimetres down to nanometres, so we have sought explanations for various aspects of its design. Here we review several aspects of the retina's functional architecture and find that all seem governed by a single principle: represent the most information for the least cost in space and energy. Specifically: (i) why are OFF ganglion cells more numerous than ON cells? Because natural scenes contain more negative than positive contrasts, and the retina matches its neural resources to represent them equally well; (ii) why do ganglion cells of a given type overlap their dendrites to achieve 3-fold coverage? Because this maximizes total information represented by the array -balancing signal-to-noise improvement against increased redundancy; (iii) why do ganglion cells form multiple arrays? Because this allows most information to be sent at lower rates, decreasing the space and energy costs for sending a given amount of information. This broad principle, operating at higher levels, probably contributes to the brain's immense computational efficiency.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/2483301" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4e4958bbc1d8e65c7638917a535beaef" rel="nofollow" data-download="{"attachment_id":50603870,"asset_id":2483301,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50603870/download_file?st=MTczOTgwNTgxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="3236631" href="https://independent.academia.edu/AdriawanAwang">Adriawan Awang</a><script data-card-contents-for-user="3236631" type="text/json">{"id":3236631,"first_name":"Adriawan","last_name":"Awang","domain_name":"independent","page_name":"AdriawanAwang","display_name":"Adriawan Awang","profile_url":"https://independent.academia.edu/AdriawanAwang?f_ri=13493","photo":"https://0.academia-photos.com/3236631/1066881/4189619/s65_adriawan.awang.jpg"}</script></span></span></li><li class="js-paper-rank-work_2483301 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="2483301"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 2483301, container: ".js-paper-rank-work_2483301", });

In a previous study, movement dynamics and amplitude were separated from the kinematics of tennis players' forehand groundstrokes. In the present study, these were manipulated and tennis shots were simulated. Three conditions were created in which shot-direction differences were either preserved or removed: Dynamics-Present-Amplitude-Present (D P A P ), Dynamics-Present-Amplitude-Absent (D P A A ), and Dynamics-Absent-Amplitude-Present (D A A P ). Nineteen low-skill and 15 intermediate-skill tennis players watched the simulated shots and predicted shot direction from movements prior to ball-racket contact only. Percent of correctly predicted shots per condition was measured. On average, both groups' performance was superior when the dynamics were present (the D P A P and D P A A conditions) compared to when it was absent (the D A A P condition). However, the intermediate-skill players performed above chance independent of amplitude differences in shots (i.e., both the D P A P and D P A A conditions), whereas the lowskill group only performed above chance when amplitude differences were absent (the D P A A condition). These results suggest that the movement's dynamics but not their amplitude provides information from which tennis-shot direction can be anticipated.

This study supports the hypothesis of an impairment of a specific magnocellular function in dyslexia. q","downloadable_attachments":[{"id":44402193,"asset_id":14251550,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":33219193,"first_name":"Helmut","last_name":"Remschmidt","domain_name":"independent","page_name":"HelmutRemschmidt","display_name":"Helmut Remschmidt","profile_url":"https://independent.academia.edu/HelmutRemschmidt?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology?f_ri=13493","nofollow":true},{"id":237,"name":"Cognitive Science","url":"https://www.academia.edu/Documents/in/Cognitive_Science?f_ri=13493","nofollow":true},{"id":10904,"name":"Electroencephalography","url":"https://www.academia.edu/Documents/in/Electroencephalography?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true},{"id":22506,"name":"Adolescent","url":"https://www.academia.edu/Documents/in/Adolescent?f_ri=13493"},{"id":25052,"name":"Dyslexia","url":"https://www.academia.edu/Documents/in/Dyslexia?f_ri=13493"},{"id":64933,"name":"Child","url":"https://www.academia.edu/Documents/in/Child?f_ri=13493"},{"id":91756,"name":"Visual Evoked Potential","url":"https://www.academia.edu/Documents/in/Visual_Evoked_Potential?f_ri=13493"},{"id":413195,"name":"Time Factors","url":"https://www.academia.edu/Documents/in/Time_Factors?f_ri=13493"},{"id":968586,"name":"Visual Evoked Potentials","url":"https://www.academia.edu/Documents/in/Visual_Evoked_Potentials?f_ri=13493"},{"id":1239755,"name":"Neurosciences","url":"https://www.academia.edu/Documents/in/Neurosciences?f_ri=13493"},{"id":1819399,"name":"Case Control Studies","url":"https://www.academia.edu/Documents/in/Case_Control_Studies?f_ri=13493"},{"id":2234200,"name":"Functional Laterality","url":"https://www.academia.edu/Documents/in/Functional_Laterality?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_20927411" data-work_id="20927411" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/20927411/Perceiving_light_versus_material">Perceiving light versus material</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Humans rarely confuse variations in light intensity, such as shadows, shading, light sources and specular reflections, from variations in material properties, such as albedo or pigment.

Thus, the earliest OFR were strongly dependent on the motion of the major Fourier component, consistent with early spatio-temporal filtering prior to motion detection, as in the well-known energy model of motion analysis.","downloadable_attachments":[{"id":79864509,"asset_id":69965718,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":158369694,"first_name":"kevin","last_name":"Chen","domain_name":"independent","page_name":"kevinChen354","display_name":"kevin Chen","profile_url":"https://independent.academia.edu/kevinChen354?f_ri=13493","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":246,"name":"Psychophysics","url":"https://www.academia.edu/Documents/in/Psychophysics?f_ri=13493","nofollow":true},{"id":13493,"name":"Motion perception","url":"https://www.academia.edu/Documents/in/Motion_perception?f_ri=13493","nofollow":true},{"id":13766,"name":"Motion Analysis","url":"https://www.academia.edu/Documents/in/Motion_Analysis?f_ri=13493","nofollow":true},{"id":59692,"name":"Vision","url":"https://www.academia.edu/Documents/in/Vision?f_ri=13493","nofollow":true},{"id":93036,"name":"Motion Detection","url":"https://www.academia.edu/Documents/in/Motion_Detection?f_ri=13493"},{"id":135373,"name":"Contrast sensitivity","url":"https://www.academia.edu/Documents/in/Contrast_sensitivity?f_ri=13493"},{"id":143507,"name":"Eye Movements","url":"https://www.academia.edu/Documents/in/Eye_Movements?f_ri=13493"},{"id":181847,"name":"First-Order Logic","url":"https://www.academia.edu/Documents/in/First-Order_Logic?f_ri=13493"},{"id":405178,"name":"First Order Logic","url":"https://www.academia.edu/Documents/in/First_Order_Logic?f_ri=13493"},{"id":995270,"name":"Visual Motion","url":"https://www.academia.edu/Documents/in/Visual_Motion?f_ri=13493"},{"id":2444775,"name":"Psychomotor Performance","url":"https://www.academia.edu/Documents/in/Psychomotor_Performance?f_ri=13493"},{"id":2849038,"name":"photic stimulation","url":"https://www.academia.edu/Documents/in/photic_stimulation?f_ri=13493"},{"id":2922956,"name":"Psychology and Cognitive Sciences","url":"https://www.academia.edu/Documents/in/Psychology_and_Cognitive_Sciences?f_ri=13493"},{"id":3763225,"name":"Medical and Health Sciences","url":"https://www.academia.edu/Documents/in/Medical_and_Health_Sciences?f_ri=13493"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_48011462" data-work_id="48011462" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/48011462/Driving_performance_assessment_Effects_of_traffic_accident_location_and_alarm_content">Driving performance assessment: Effects of traffic accident location and alarm content</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">According to accident statistics for Taiwan, the two most common traffic accident locations in urban areas are roadway segments and intersections.

On roadway segments, most collisions are due to drivers not noticing the status of leading vehicle. At intersections, most collisions are due to the other driver failing to obey traffic signs. Using a driving simulator equipped with a collision warning system, this study investigated driving performance at different accident locations and between different alarm contents, and identified the relationship between crash occurrences and driving performance. Thirty participants, aged 20-29 years, were recruited in this study. Driving performance measures were perception-reaction time, movement-reaction time, speed and a crash. Experimental results indicated that due to different demands for processing information under different traffic conditions, driving performance differed at the two traffic accident locations. On a roadway segment, perception-reaction time for a beep was shorter than the time for a speech message. Nevertheless, at an intersection, a speech message was a great help to drivers and, thus, perception-reaction time was effectively reduced. In addition, logistic regression analysis indicates that perception-movement time had the greatest influence on crash occurrence.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/48011462" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="8656040f6e538536db1c5897ef447f14" rel="nofollow" data-download="{"attachment_id":66844725,"asset_id":48011462,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/66844725/download_file?st=MTczOTgwNTgxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="44580160" href="https://independent.academia.edu/ShunHuiChang">ShunHui Chang</a><script data-card-contents-for-user="44580160" type="text/json">{"id":44580160,"first_name":"ShunHui","last_name":"Chang","domain_name":"independent","page_name":"ShunHuiChang","display_name":"ShunHui Chang","profile_url":"https://independent.academia.edu/ShunHuiChang?f_ri=13493","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_48011462 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="48011462"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 48011462, container: ".js-paper-rank-work_48011462", });
