Global and local modulation of inhibitory processes in task switching
Final Report Abstract
This project aimed at elucidating effects of various factors on n – 2 repetition costs. These costs are used as a marker for inhibition of currently irrelevant information during task switching. It was investigated whether factors that modulate the experimental setting cause n – 2 repetition costs to inflate (indicating enhanced inhibition), or whether they decrease the effect, indicating less inhibition. In 6 peer-reviewed publications, it was demonstrated that the appearance and size of n – 2 repetition costs dynamically changes in accordance with requirements of the experimental setting. Specifically, n – 2 repetition costs were affected by factors which do not modulate specific task content directly, but which exert their influence on the whole task space and relations among tasks. This indicates that inhibition during task switching is not exerted in an all-or-none fashion, but is employed in a flexible way depending on how much inhibition is required due to characteristics of the whole task environment. These findings are of importance for the understanding of cognitive control processes underlying the flexible control of human behavior in accordance with changes of the environment.
