Strategic modulation of response inhibition in task-switching
Residual activations from previous task performance usually prime the system toward response repetition. However, when the task switches, the repetition of a response (RR) produces longer reaction times and higher error rates. Some researchers assumed that these RR costs reflect strategic inhibition of just executed responses and that this serves for preventing perseveration errors. We investig...
متن کاملResponse Inhibition Modulates Response Conflict in Task Switching
Although response repetition (RR) effects vary considerably between conditions and studies, little is known about the causes. Recently, RR costs on task switch trials have been found to be larger for incongruent stimuli that activate both alternative responses than for neutral ones. Here, we investigated if this modulation can be explained by an amplification of response conflict account (ARC)....
متن کاملResponse inhibition under task switching: its strength depends on the amount of task-irrelevant response activation.
Under task switch conditions, response repetitions usually produce benefits if the task also repeats, but costs if the task switches. So far, it is largely undecided how to account for these effects. In the present study, we provide additional evidence in favor of the account that each response is inhibited in order to prevent its accidental re-execution. To test this hypothesis, the risk of an...
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 کاملExcessive response-repetition costs under task switching: how response inhibition amplifies response conflict.
The size of response-repetition (RR) costs, which are usually observed on task-switch trials, strongly varies between conditions with univalent and bivalent stimuli. To test whether top-down or bottom-up processes can account for this effect, we assessed in Experiment 1 baselines for univalent and bivalent stimulus conditions (i.e., for stimuli that are associated with either 1 or 2 tasks). Exp...
