The aim of the present study was to examine the contribution of overlapping response sets to the occurrence of task inhibition, measured as n-2 task repetition cost. We had subjects switch among four tasks. Three tasks overlapped on both stimulus set and response set. A fourth, neutral, univalent task never overlapped on the stimulus set but, across three experiments, varied in terms of the degree of overlap in the response set. We found that overlap in response set affects task inhibition. We suggest that response set overlap increases the competition among tasks and, thus, triggers task inhibition to resolve this competition.
本研究的目的是检验重叠反应集对任务抑制发生的影响，任务抑制以n-2任务重复代价来衡量。我们让受试者在四项任务之间进行切换。其中三项任务在刺激集和反应集上都有重叠。第四项中性、单值任务在刺激集上从不重叠，但在三个实验中，其反应集的重叠程度有所不同。我们发现反应集的重叠会影响任务抑制。我们认为反应集重叠会增加任务之间的竞争，从而触发任务抑制来解决这种竞争。
