The relationship between a performer's conscious involvement or investment in movement control and monitoring and the ability to inhibit the movement is still unclear. We conducted three experiments to investigate whether a higher inclination for conscious movement investment benefits the inhibition of a simple keypress response. In all experiments, the inclination for conscious movement investment was measured with the Movement-Specific Reinvestment Scale. In Experiment 1, participants performed the go/no-go task and conscious investment was manipulated by directing conscious attention either to the finger movement (i.e., internal focus) or to the resulting motion of the key (i.e., external focus). The results showed that neither the participants' inclination for conscious movement investment, nor the direction of conscious attention affected inhibition performance. In Experiment 2, participants performed the stop-signal task, which is more attention demanding than the go/no-go task. The results showed that participants with a high or low inclination for conscious movement investment did not differ in inhibition performance. In Experiment 3 an ego-depletion procedure was included that limits resources for conscious movement investment. Before and after this ego-depletion procedure, participants performed the stop-signal task. The results showed that participants with a high inclination for conscious movement investment slowed down inhibition when they felt mentally depleted, while no slowing down of inhibition was found among participants who felt less depleted and/or had a low inclination for conscious movement investment. Together, the study provides evidence that increased conscious movement investment is beneficial for movement inhibition. Yet, these effects only emerge against the dynamic background of interacting individual (e.g., inclination for conscious movement investment, available attentional resources) and task constraints (e.g., task difficulty).
表演者在动作控制与监测中的意识参与或投入与抑制动作的能力之间的关系仍不明确。我们进行了三项实验，以探究更高的意识动作投入倾向是否有利于抑制简单的按键反应。在所有实验中，意识动作投入倾向均通过特定动作再投入量表来衡量。在实验1中，参与者执行了停止信号任务，通过将意识注意力导向手指动作（即内部焦点）或按键产生的动作（即外部焦点）来操纵意识投入。结果表明，参与者的意识动作投入倾向和意识注意力方向均未影响抑制表现。在实验2中，参与者执行了停止信号任务，该任务比停止信号任务对注意力的要求更高。结果表明，意识动作投入倾向高或低的参与者在抑制表现上没有差异。在实验3中，纳入了一项自我损耗程序，该程序限制了意识动作投入的资源。在这项自我损耗程序前后，参与者执行了停止信号任务。结果表明，意识动作投入倾向高的参与者在感到精神耗竭时抑制速度减慢，而在感觉耗竭程度较低和/或意识动作投入倾向低的参与者中未发现抑制速度减慢的情况。总之，该研究提供了证据表明，增加意识动作投入有利于动作抑制。然而，这些效应仅在个体（如意识动作投入倾向、可用注意力资源）和任务限制（如任务难度）相互作用的动态背景下才会出现。
