The response-effect compatibility (REC) paradigm provides an elegant tool for studying the impact of anticipated action effects on action control. Converging evidence for such anticipative processes has mainly emerged from tasks that require simple, discrete actions, whereas tasks that require more complex, continuous actions such as wheel-rotation responses have yielded discrepant results. We investigate the role of two moderating variables that have only played a minor role in effect-based theories of human action control and may account for this discrepancy: (1) the degree of dimensional overlap (rather than its mere presence) and (2) directing attention towards the action effects. The results of three experiments suggest that both factors are crucial in determining the size of REC effects for continuous wheel-rotation responses: Reliable REC effects were obtained, and they were larger with high than with low dimensional overlap and when attending to the effects than when not. Thus, the study points toward important preconditions that determine whether and how effect anticipations affect complex motor actions.
反应-效应兼容性（REC）范式为研究预期动作效应对动作控制的影响提供了一个精妙的工具。此类预期过程的趋同证据主要来自于需要简单、离散动作的任务，而需要更复杂、连续动作（如轮盘旋转反应）的任务则产生了不一致的结果。我们研究了两个调节变量的作用，这两个变量在基于效应的人类动作控制理论中仅发挥了次要作用，且可能解释了这种差异：（1）维度重叠的程度（而非仅仅是其存在）和（2）将注意力导向动作效应。三个实验的结果表明，这两个因素对于确定连续轮盘旋转反应的REC效应大小都至关重要：获得了可靠的REC效应，且在维度重叠高时比低时更大，在关注效应时比不关注时更大。因此，该研究指出了决定效应预期是否以及如何影响复杂运动动作的重要前提条件。
