The congruency effect observed in distracter interference tasks is usually smaller after incongruent relative to congruent trials. However, the nature of control processes underlying this congruency sequence effect (CSE) remains a topic of active debate. For example, while some researchers have suggested that these processes are recruited only when participants utilize the same response mode (e.g., the same hand) to respond in consecutive trials, others have argued that these processes can operate independently of response mode. To distinguish between these views, we investigated whether changes of response mode across consecutive trials influence the CSE in a prime-probe task (Experiment 1) or a flanker task (Experiment 2). Such changes did not influence the CSE in either task. Further, the CSE was significant even when participants utilized different response modes (i.e., different hands) to respond in consecutive trials. These findings indicate that control processes underlying the CSE can operate independently of response mode and thereby clarify the nature of control processes that minimize distraction from irrelevant stimuli.
在干扰项干扰任务中观察到的一致性效应,通常在不一致试验后相对于一致试验会更小。然而,这种一致性序列效应(CSE)背后的控制过程的本质仍是一个活跃的辩论话题。例如,虽然一些研究人员认为,只有当参与者在连续试验中使用相同的反应方式(如同一手)做出反应时,才会调用这些过程,但另一些人则认为,这些过程可以独立于反应方式运行。为了区分这些观点,我们研究了连续试验中反应方式的变化是否会在启动探测任务(实验1)或侧翼任务(实验2)中影响CSE。这种变化在任何一个任务中都没有影响CSE。此外,即使参与者在连续试验中使用不同的反应方式(即不同的手)做出反应,CSE仍然显著。这些发现表明,CSE背后的控制过程可以独立于反应方式运行,从而阐明了将无关刺激的干扰降至最低的控制过程的本质。
