四个任务转换实验考察了任务集重组的外源性成分的概念(即，在没有任务相关的图形刺激的情况下，转移不启动的任务集所需的过程)。作者改变了刺激-反应(SR)映射规则的复杂性和熟悉性，以产生不同的耗时的重新配置需求。考虑到刺激重复被排除在分析之外，规则更复杂或不太熟悉的任务没有显示出更高的转换成本。这些结果并不支持外生重构的观点。此外，刺激重复增加了任务转换的成本，而且对于反应选择难度增加的任务来说，这种情况不成比例地增加，从而表明对刺激序列的不充分控制可能会产生与外源性重新配置账户预测的结果相似的结果。
Four task-switching experiments examined the notion of an exogenous component of task-set reconfiguration (i.e., a process needed to shift task set that is not initiated in the absence of a task-associated figuration stimulus). The authors varied the complexity and familiarity of stimulus-response (SR) mapping rules to produce differentially time-consuming reconfiguration demands. Tasks with more complex or less familiar rules did not display increased switch costs, given that stimulus repetitions were excluded from the analysis. These results do not support the idea of exogenous reconfiguration. Moreover, stimulus repetitions inflated task-switch costs and did so disproportionately for tasks with increased response selection difficulty, thereby demonstrating that insufficient control of the sequence of stimuli may yield results that mimic those predicted by exogenous reconfiguration accounts.
