It is increasingly recognized that motor routines dynamically shape the processing of sensory inflow (e.g., when hand movements are used to feel a texture or identify an object). In the present research, we captured the shaping of auditory perception by movement in humans by taking advantage of a specific context: music. Participants listened to a repeated rhythmical sequence before and after moving their bodies to this rhythm in a specific meter. We found that the brain responses to the rhythm (as recorded with electroencephalography) after body movement were significantly enhanced at frequencies related to the meter to which the participants had moved. These results provide evidence that body movement can selectively shape the subsequent internal representation of auditory rhythms.
人们越来越认识到，运动常规会动态地塑造对感觉传入的处理（例如，当手的运动被用来感受质地或识别物体时）。在本研究中，我们利用特定的音乐背景，通过人体运动来捕捉听觉感知的塑造。参与者在按照特定节拍移动身体来配合节奏之前和之后，都会听到重复的节奏序列。我们发现，大脑对节奏的反应（用电极记录）在身体运动后在与参与者移动的节拍相关的频率上显著增强。这些结果提供了证据，证明身体运动可以选择性地塑造随后对听觉节奏的内部表示。
