知觉的理论模型假设信心与感觉处理的质量或强度有关。与这种直观的观点相反，我们在本研究中表明，运动系统也有助于知觉信心的判断。在两个实验中，我们使用经颅磁刺激（TMS）来操纵前运动皮层中的反应特异性表征，选择性地破坏视觉辨别判断的反应后信心。具体来说，刺激与未选择的反应相关的运动表征降低了正确反应的信心，从而降低了元认知能力，而不改变视觉辨别能力。TMS对信心的影响，观察时，刺激之前和之后的反应发生，这表明，信心取决于后期的元认知过程。这些结果表明，前运动皮层中的动作特异性信息有助于知觉信心，从而限制了知觉信心和元认知的模型。
Theoretical models of perception assume that confidence is related to the quality or strength of sensory processing. Counter to this intuitive view, we showed in the present research that the motor system also contributes to judgments of perceptual confidence. In two experiments, we used transcranial magnetic stimulation (TMS) to manipulate response-specific representations in the premotor cortex, selectively disrupting postresponse confidence in visual discrimination judgments. Specifically, stimulation of the motor representation associated with the unchosen response reduced confidence in correct responses, thereby reducing metacognitive capacity without changing visual discrimination performance. Effects of TMS on confidence were observed when stimulation was applied both before and after the response occurred, which suggests that confidence depends on late-stage metacognitive processes. These results place constraints on models of perceptual confidence and metacognition by revealing that action-specific information in the premotor cortex contributes to perceptual confidence.
