Action planning, but not action execution, in speeded tasks is typically faster when responses and their effects are compatible than when they are incompatible. We tested whether response-effect compatibility (REC) affects the execution of music-like sequential actions that require temporal regularity rather than rapidity. Musicians responded to metronomic visual stimuli by producing sequences of three taps at a specific tempo on three vertically aligned keys. Each tap triggered a tone. Key-to-tone mapping was either compatible or incompatible in terms of spatial height and pitch height. The results indicated that tap timing was more accurate with compatible than with incompatible mappings, both for taps produced before (Tap 1) and after (Taps 2 and 3) the onset of auditory feedback. Thus, the observed influence of REC on action execution was not due exclusively to actual auditory feedback. The anticipation of distal action effects may be involved in planning the dynamics of temporally precise movements.
在快速任务中，当反应及其效果兼容时，动作规划（而非动作执行）通常比不兼容时更快。我们测试了反应-效果兼容性（REC）是否会影响需要时间规律性而非速度的类似音乐的连续动作的执行。音乐家通过在三个垂直对齐的按键上以特定节奏敲击三次来对节拍器视觉刺激做出反应。每次敲击都会触发一个音调。按键与音调的映射在空间高度和音高方面要么兼容，要么不兼容。结果表明，无论是在听觉反馈开始之前（敲击1）还是之后（敲击2和3）产生的敲击，兼容映射下的敲击时间都比不兼容映射下更准确。因此，观察到的REC对动作执行的影响并非完全归因于实际的听觉反馈。对远端动作效果的预期可能参与了时间精确动作动态的规划。
