However, it is an open issue what neural processes underlie this effect. In the present study, healthy volunteers underwent functional magnetic resonance imaging (fMRI) while performing a cued task switching paradigm, in which geometric objects had to be classified according to either color or shape. By manipulating the duration of the cue-target-interval (CTI) in the range between 0 and 1500 ms, we were able to dissociate brain activity changes related to the processing of either the cue or the target. A network of frontal and parietal brain areas was activated during advance preparation for the upcoming task independent of whether the task was switched or repeated. The same brain regions also showed increased neural activity in response to targets without advance preparation in contrast to targets with advance preparation which only elicited activations in areas involved in visual processing and motor execution. These findings strongly argue for a Ftask-set activation perspective_ on advance preparation in task switching [Altmann, E.M., 2004. Advance preparation in task switching: what work is being done? Psychol. Sci. 15,[616][617][618][619][620][621][622], whereas no empirical support could be found for the Fmental gear changing model_ of task switching as no significant brain activity changes were observable in association with task switches, switch costs, or the interaction effect of advance preparation on switch costs. Finally, in the light of previous behavioral studies on interference effects of articulatory suppression on task preparation in humans, the present findings are compatible with the assumption that verbalization mechanisms, e.g., the retrieval of a verbal task or goal representation into working memory may be a functional component of advance configuration of task-sets.

Psychology, 2010</p><p class="ds-related-work--abstract ds2-5-body-sm">Recent research has taken advantage of the temporal and spatial resolution of event-related brain potentials (ERPs) and functional magnetic resonance imaging (fMRI) to identify the time course and neural circuitry of preparatory processes required to switch between different tasks. Here we overview some key findings contributing to understanding strategic processes in advance preparation. Findings from these methodologies are compatible with advance preparation conceptualized as a set of processes activated for both switch and repeat trials, but with substantial variability as a function of individual differences and task requirements. We then highlight new approaches that attempt to capitalize on this variability to link behavior and brain activation patterns. One approach examines correlations among behavioral, ERP and fMRI measures. A second "model-based" approach accounts for differences in preparatory processes by estimating quantitative model parameters that reflect latent psychological processes. We argue that integration of behavioral and neuroscientific methodologies is key to understanding the complex nature of advance preparation in task-switching.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Advance preparation in task-switching: converging evidence from behavioural, brain activation and model-based approaches.","attachmentId":38243677,"attachmentType":"pdf","work_url":"https://www.academia.edu/14240741/Advance_preparation_in_task_switching_converging_evidence_from_behavioural_brain_activation_and_model_based_approaches","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/14240741/Advance_preparation_in_task_switching_converging_evidence_from_behavioural_brain_activation_and_model_based_approaches"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="4" data-entity-id="47396191" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/47396191/Lateralized_task_shift_effects_in_Brocas_and_Wernickes_regions_and_in_visual_word_form_area_are_selective_for_conceptual_content_and_reflect_trial_history">Lateralized task shift effects in Broca's and Wernicke's regions and in visual word form area are selective for conceptual content and reflect trial history</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="10919498" href="https://independent.academia.edu/J%C3%A1kupMichaelsen">Jákup Michaelsen</a></div><p class="ds-related-work--metadata ds2-5-body-xs">NeuroImage, 2014</p><p class="ds-related-work--abstract ds2-5-body-sm">We investigated whether lateralized BOLD-fMRI activations in Broca's region, Wernicke's region and visual word form area (VWFA) reflect task shift costs and to which extent these effects are specific to language related task shifts. We employed a linguistic one-back memory paradigm where participants (n = 58) on each trial responded to whether a given word was the same as the previous word. In concordance with previous findings we found that conceptual shifts (CS), i.e. new words, elicited a strongly left-lateralized response in all three regions compared to repeat words. Words were sometimes presented through the visual modality (read) and sometimes through the auditory modality (spoken). This enabled the study of perceptual modality shifts (PS) relative to trials that stayed in the same modality as the previous trials. Again, we found a strongly left-lateralized effect in all regions. This was independent of whether the word was a CS or not, suggesting that linguistic translation across modalities taxes the same system as CS. Response shifts (RS), on the other hand, when shifting from one response (e.g. reporting a repeat word) to another (e.g. reporting a new word) did not yield an observable left lateralized response in any of the regions, suggesting that the lateralized task shift cost effects in these regions are not shared by all types of task shifts. Lateralization for individual tasks was found to be correlated across brain regions, but not across tasks, suggesting that lateralization may not be a unitary phenomenon, but vary across participants according to task demands. Both response time and lateralization were found to reflect the demands not only of the current trial but also of the previous trial, illustrating the context dependency of even simple cognitive tasks.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Lateralized task shift effects in Broca's and Wernicke's regions and in visual word form area are selective for conceptual content and reflect trial history","attachmentId":66509111,"attachmentType":"pdf","work_url":"https://www.academia.edu/47396191/Lateralized_task_shift_effects_in_Brocas_and_Wernickes_regions_and_in_visual_word_form_area_are_selective_for_conceptual_content_and_reflect_trial_history","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/47396191/Lateralized_task_shift_effects_in_Brocas_and_Wernickes_regions_and_in_visual_word_form_area_are_selective_for_conceptual_content_and_reflect_trial_history"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="8331754" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/8331754/Dissociating_strategy_dependent_and_independent_components_in_task_preparation">Dissociating strategy-dependent and independent components in task preparation</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="90921" href="https://tilburguniversity.academia.edu/WouterDeBaene">Wouter De Baene</a></div><p class="ds-related-work--abstract ds2-5-body-sm">A central aspect of cognitive control is the capacity to anticipatorily prepare for specific task requirements prior to carrying out a task. To study the changes caused by task preparation, the cued task-switching paradigm has generally been used. While research on anticipatory control has long focused on general processing differences between switch and repeat trials, more recent research suggests that contextual variations strongly modulate such differences. In the current paper, we argue that anticipatory task set preparation strongly depends on contextual variables leading to different strategies to prepare for an upcoming task. We provide behavioral as well as neuroscientific evidence for this claim. Furthermore, we show that some preparatory processes are sensitive to strategic modulations whereas other preparatory processes are not. Based on this, we propose a functional dissociation within the fronto-parietal network involved in task preparation.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Dissociating strategy-dependent and independent components in task preparation","attachmentId":34736411,"attachmentType":"pdf","work_url":"https://www.academia.edu/8331754/Dissociating_strategy_dependent_and_independent_components_in_task_preparation","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/8331754/Dissociating_strategy_dependent_and_independent_components_in_task_preparation"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="462297" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/462297/Anticipatory_Reconfiguration_Elicited_by_Fully_and_Partially_Informative_Cues_That_Validly_Predict_a_Switch_In_Task">Anticipatory Reconfiguration Elicited by Fully and Partially Informative Cues That Validly Predict a Switch In Task</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="116740" href="https://newcastle-au.academia.edu/FriniKarayanidis">Frini Karayanidis</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Cognitive, …, 2009</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Anticipatory Reconfiguration Elicited by Fully and Partially Informative Cues That Validly Predict a Switch In Task","attachmentId":51400483,"attachmentType":"pdf","work_url":"https://www.academia.edu/462297/Anticipatory_Reconfiguration_Elicited_by_Fully_and_Partially_Informative_Cues_That_Validly_Predict_a_Switch_In_Task","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/462297/Anticipatory_Reconfiguration_Elicited_by_Fully_and_Partially_Informative_Cues_That_Validly_Predict_a_Switch_In_Task"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="12648189" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/12648189/The_role_of_dual_task_and_task_switch_in_prospective_memory_Behavioural_data_and_neural_correlates">The role of dual-task and task-switch in prospective memory: Behavioural data and neural correlates</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="31634155" href="https://independent.academia.edu/PatriziaBisiacchi">Patrizia Bisiacchi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Neuropsychologia, 2009</p><p class="ds-related-work--abstract ds2-5-body-sm">Event-based prospective memory (PM) requires remembering the delayed execution of an intended action in response to a pre-specified PM cue while being actively engaged in an ongoing task in which the cue is embedded. To date, experimental paradigms vary as to whether or not they require participants immediately to stop working on the ongoing task whenever they encounter a PM event (cue) and directly switch to the prospective action (task-switch approach). Alternatively, several other paradigms used in the literature encourage participants to continue working on the ongoing task item after the cue, and only then, perform the prospective action (dual-task approach). The present study explores the possible behavioural and electrophysiological effects that both approaches may have on PM performance. Seventeen young adults performed both versions of a standard PM task in a counterbalanced order during which behavioural data and electroencephalogram (EEG) were recorded. Behavioural data showed a decrement in PM performance in the task-switch compared to the dual-task condition. In addition, EEG data revealed differences between the dual-task and task-switch approach in event-related potential (ERP) components associated with response inhibition and with post-retrieval monitoring (i.e. late positive complex). No differences between the two tasks were found with regard to the PM event detection processes (i.e. N300) and the retrieval of the intended action from long-term memory. In sum, findings demonstrate that it does make a difference which task approach is applied and suggest that dual-task and task-switch paradigms may result in different processing and neurophysiological dynamics particularly concerning attentional resources and cognitive control.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"The role of dual-task and task-switch in prospective memory: Behavioural data and neural correlates","attachmentId":46030236,"attachmentType":"pdf","work_url":"https://www.academia.edu/12648189/The_role_of_dual_task_and_task_switch_in_prospective_memory_Behavioural_data_and_neural_correlates","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/12648189/The_role_of_dual_task_and_task_switch_in_prospective_memory_Behavioural_data_and_neural_correlates"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="3493407" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/3493407/Dont_think_of_a_white_bear_An_fMRI_investigation_of_the_effects_of_sequential_instructional_sets_on_cortical_activity_in_a_task_switching_paradigm">Don't think of a white bear: An fMRI investigation of the effects of sequential instructional sets on cortical activity in a task-switching paradigm</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="3063017" href="https://kesslerfoundation.academia.edu/GlennWylie">Glenn Wylie</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Human Brain Mapping, 2004</p><p class="ds-related-work--abstract ds2-5-body-sm">Using functional magnetic resonance imaging (fMRI), we investigated processes involved in switching between two ongoing tasks, thought to be paradigmatic of executive control processes. Subjects were considerably slower and less accurate when switching between two tasks than when repeatedly carrying out one task, so-called "switch costs." Switch costs, however, generally occur only when more than one task is associated with each stimulus type. This has led to the surmise that switch costs may be due largely to ongoing interference from previously learned stimulus-response (S-R) associations, which are no longer relevant for the task at hand. We used a paradigm that specifically assessed this hypothesis and investigated three stages. In Stage 1, a single task was carried out with each stimulus type; in Stage 2, a second novel task was introduced for each stimulus type; and in Stage 3, subjects reverted to carrying out solely the original tasks (as in Stage 1). In Stage 1, only one task was associated with each stimulus type, whereas two tasks were associated with each stimulus type in Stages 2 and 3. We compared images obtained during Stage 3 to those obtained during Stage 1 and show that during Stage 3, there was robust activation in the network of areas associated with the Stage 2 tasks, even though these tasks were no longer relevant. Our data strongly suggest that switch costs may derive largely from continued activation of areas associated with carrying out the now-irrelevant task(s). We posit that a large component of executive control processes involves resolution of competition between potentially relevant tasks. Our data also revealed widespread activation of a frontoparietal network of areas, and we discuss how this network might be involved in mediating this competition.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Don't think of a white bear: An fMRI investigation of the effects of sequential instructional sets on cortical activity in a task-switching paradigm","attachmentId":50263428,"attachmentType":"pdf","work_url":"https://www.academia.edu/3493407/Dont_think_of_a_white_bear_An_fMRI_investigation_of_the_effects_of_sequential_instructional_sets_on_cortical_activity_in_a_task_switching_paradigm","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/3493407/Dont_think_of_a_white_bear_An_fMRI_investigation_of_the_effects_of_sequential_instructional_sets_on_cortical_activity_in_a_task_switching_paradigm"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="13050804" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/13050804/Task_preparation_and_neural_activation_in_stimulus_specific_brain_regions_An_fMRI_study_with_the_cued_task_switching_paradigm">Task preparation and neural activation in stimulus-specific brain regions: An fMRI study with the cued task-switching paradigm</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="32286252" href="https://hu-berlin.academia.edu/TorstenSchubert">Torsten Schubert</a></div><p class="ds-related-work--abstract ds2-5-body-sm">To investigate the role of posterior brain regions related to task-relevant stimulus processing in task preparation, we used a cued task-switching paradigm in which a pre-cue informed participants about the upcoming task on a trial: face discrimination or number comparison. Employing an event-related fMRI design, we examined for changes of activity in face-and number-related posterior brain regions (right fusiform face area (FFA) and right intraparietal sulcus (IPSnum), respectively), and explored the functional connectivity of these areas with other brain regions, during the (preparation) interval between cue onset and onset of the (to-be-responded) target stimulus. The results revealed task-relevant posterior brain regions to be modulated during this period: activation in task-relevant stimulus-specific regions was selectively enhanced and their functional connectivity to task-relevant anterior brain regions strengthened (right FFA -face task, right IPSnum -number task) while participants prepared for the cued task. Additionally, activity in task-relevant posterior brain regions was influenced by residual activation from the preceding trial in the right FFA and the right IPSnum, respectively. These findings indicate that, during task preparation, the activation pattern in currently task-relevant posterior brain regions is shaped by residual activation as well as preparatory modulation prior to the onset of the critical stimulus, even without participants being instructed to imagine the stimulus.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Task preparation and neural activation in stimulus-specific brain regions: An fMRI study with the cued task-switching paradigm","attachmentId":45738782,"attachmentType":"pdf","work_url":"https://www.academia.edu/13050804/Task_preparation_and_neural_activation_in_stimulus_specific_brain_regions_An_fMRI_study_with_the_cued_task_switching_paradigm","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/13050804/Task_preparation_and_neural_activation_in_stimulus_specific_brain_regions_An_fMRI_study_with_the_cued_task_switching_paradigm"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":43079393,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":43079393,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_43079393" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
