Stimulus-response complexity influences task-set inhibition in task switching.

ABSTRACT: Previous studies have found that inhibiting a task set plays an important role in task switching. However, the impact of stimulus-response (S-R) complexity on this inhibition processing has not been explored. In this study, we applied the backward inhibition paradigm (switching between tasks A, B, and C, presented in sets of three) in order to investigate inhibition performance under different S-R complexities caused by corresponding S-R mappings. The results showed that the difficult condition resulted in a greater switch cost than the moderate and easy conditions. Furthermore, we found a significant n-2 repetition cost under the easy S-R complexity that was reversed under the difficult S-R complexity. To verify stability of the reversed n-2 repetition cost in the difficult
