重复效应通常有助于揭示有关心理结构和过程的信息。通常，当刺激或反应重复时，就会观察到积极的效果。然而，在任务转移的研究中也发现，如果任务转移，重复的反应会产生负面影响。虽然已经提出了几种机制来解释任务转移和反应重复之间的这种相互作用，但许多细节仍然是开放的。因此，我们进行了一系列的四个实验来回答两个问题。首先，运动反应是产生与反应相关的重复效应所必需的，还是反应激活就足够了？第二，意外重复执行最后一次响应的风险是否会影响重复成本？结果表明，反应激活本身就能产生重复效应。此外，意外响应重新执行的风险在很大程度上调节了这些影响。
Repetition effects are often helpful in revealing information about mental structures and processes. Usually, positive effects have been observed when the stimuli or responses are repeated. However, in task shift studies it has also been found that response repetitions can produce negative effects if the task shifts. Although several mechanisms have been proposed to account for this interaction between task shifting and response repetition, many details remain open. Therefore, a series of four experiments was conducted to answer two questions. First, are motor responses necessary to produce response-related repetition effects, or is response activation sufficient? Second, does the risk of an accidental re-execution of the last response affect the repetition costs? The results show that response activation alone can produce repetition effects. Furthermore, the risk of accidental response re-execution largely modulates these effects.
