This study takes inventory of available evidence on response repetition (RR) effects in task switching, in particular the evidence for RR cost when the task switches. The review reveals that relatively few task-switching studies in which RR effects were addressed have shown statistical support for RR cost, and that almost all are affected by 1 of 2 potential artifacts, either a response bias caused by disallowing stimulus repetitions or the effect of including stimulus repetitions in data analysis. New results with these factors controlled support an episodic retrieval model in which features of the retrieved trace, including the stimulus but also the task, task cue, and response, facilitate or interfere with performance depending on whether they match or mismatch the current processing context.
本研究对任务转换中反应重复（RR）效应的现有证据进行了梳理，特别是在任务转换时 RR 效应的证据。综述发现，在涉及 RR 效应的任务转换研究中，很少有研究显示出 RR 成本的统计支持，而且几乎所有研究都受到 1 种潜在的人为因素的影响，要么是由于不允许刺激重复而导致的反应偏差，要么是由于将刺激重复纳入数据分析而产生的影响。控制这些因素的新结果支持了一种情景提取模型，在该模型中，提取轨迹的特征，包括刺激，还包括任务、任务提示和反应，根据它们是否与当前处理上下文匹配或不匹配，促进或干扰性能。
