This study examined the interaction of response repetition and response cuing in a finger cuing task with a short and a long cue-stimulus interval (CSI). We observed shorter reaction times (RTs) with increasing CSI and a substantial response repetition benefit. However, this benefit was abolished at the long CSI, suggesting that response cuing neutralized the repetition effect. According to additive-factors logic, the observed interaction suggests that both repetition and cuing exert their influence on a common processing stage, which we identify as the response selection stage. We argue that cuing and repetition effects are expressions of distinct mental operations: cuing is based on intentional response code activation, whereas repetition is based on sequential, automatic response code priming. Cue-based intentional code activation starts slowly and increases with CSI, but sequential response priming is independent of CSI, explaining why cuing abolishes the response repetition benefit at the long CSI.
本研究在一个手指提示任务中，考察了反应重复与反应提示在短提示-刺激间隔（CSI）和长提示-刺激间隔条件下的相互作用。我们观察到，随着CSI增加，反应时间（RT）缩短，并且存在显著的反应重复优势。然而，在长CSI条件下，这种优势消失了，这表明反应提示抵消了重复效应。根据相加因素逻辑，观察到的这种相互作用表明，重复和提示都对一个共同的加工阶段产生影响，我们将这个阶段确定为反应选择阶段。我们认为，提示效应和重复效应是不同心理操作的表现：提示基于有意的反应代码激活，而重复基于连续的、自动的反应代码启动。基于提示的有意代码激活开始时较慢，并随着CSI增加而增强，但连续的反应启动与CSI无关，这就解释了为什么在长CSI条件下提示会消除反应重复优势。
