Differential Preparation Intervals Modulate Repetition Processes in Task Switching: An ERP Study
In task-switching paradigms, reaction times (RTs) switch cost (SC) and the neural correlates underlying the SC are affected by different preparation intervals. However, little is known about the effect of the preparation interval on the repetition processes in task-switching. To examine this effect we utilized a cued task-switching paradigm with long sequences of repeated trials. Response-stimu...
متن کاملTask inhibition and task repetition in task switching
In task-switching experiments with three tasks, the relative cost of an N 2 task repetition (task sequence ABA) compared to a task switch (task sequence CBA) is referred to as N 2 repetition cost. N 2 repetition cost is assumed to reflect persisting inhibition of a task that was recently switched away from. In two experiments, we explored whether the occurrence of task repetitions has an influe...
متن کاملStimulus-level interference disrupts repetition benefit during task switching in middle childhood
The task-switching paradigm provides a powerful tool to measure the development of core cognitive control processes. In this study, we use the alternating runs task-switching paradigm to assess preparatory control processes involved in flexibly preparing for a predictable change in task and stimulus-driven control processes involved in controlling stimulus-level interference. We present three e...
متن کامل[Stimulus set and response set in task switching: a comparison using ERP].
Event-related potential (ERP) and reaction time (RT) were recorded to investigate the time course of processes involved in set switching. The cued set-switching paradigm required participants to switch stimulus task sets between male and female face-images memorized as targets prior to a trial block and response task sets between two stimulus-response mappings for each stimulus task. Replicatin...
متن کاملStimulus-related priming during task switching.
Task switch cost (the deficit of performing a new task vs. a repeated task) has been partly attributed to priming of the repeated task, as well as to inappropriate preparation for the switched task. In the present study, we examined the nature of the priming effect by repeating stimulus-related processes, such as stimulus encoding or stimulus identification. We adopted a partial-overlap task-sw...
