Abstract

The switch cost, which represents cognitive flexibility, is known to be caused by task-set reconfiguration and task-set inertia. This study aimed to specifically evaluate the contributions of these two cognitive processes to switch costs in cued and voluntary task switching paradigms by excluding additional cost induced from cue- and task-selection processes. For this purpose, we developed experimental tasks that required participants to respond both to the task cue and choice cue, and the task-set inertia and preparation times were manipulated based on the cue responses. Results showed that the switch cost in the voluntary task switching decreased as preparation times increased whereas it was unrelated with task-set inertia. Reversely, the switch cost in the cued task switching decreased when task-set inertia decreased but it was not associated with preparation times. This study suggests that different aspects of cognitive flexibility can be identified through the two task switching procedures.
