人们自然会随着音乐跳舞，研究表明，有节奏的听觉刺激有助于产生精确定时的身体动作。如果运动机制与听觉时间处理密切相关，就像听觉时间处理促进运动产生一样，产生动作可能会增强听觉时间敏感性。我们测试了这个新的假设与标准的时间平分范例，其中的斜率的时间平分功能提供了一个时间敏感性的措施。当参与者通过按键启动每个听觉刺激序列时，听觉时间感知的平分斜率比他们被动地听到每个序列时更陡，表明启动动作增强了听觉时间敏感性。这种增强是特定于听觉模态的，因为主动启动每个序列并没有增强视觉时间敏感性。对照实验排除了与按键相关的触觉增加听觉时间敏感性的可能性。两者合计，这些结果表明听觉时间知觉和运动机制之间的独特的互惠关系。由于听觉感知促进精确定时的运动，产生动作增强听觉时间敏感性。
People naturally dance to music, and research has shown that rhythmic auditory stimuli facilitate production of precisely timed body movements. If motor mechanisms are closely linked to auditory temporal processing, just as auditory temporal processing facilitates movement production, producing action might reciprocally enhance auditory temporal sensitivity. We tested this novel hypothesis with a standard temporal-bisection paradigm, in which the slope of the temporal-bisection function provides a measure of temporal sensitivity. The bisection slope for auditory time perception was steeper when participants initiated each auditory stimulus sequence via a keypress than when they passively heard each sequence, demonstrating that initiating action enhances auditory temporal sensitivity. This enhancement is specific to the auditory modality, because voluntarily initiating each sequence did not enhance visual temporal sensitivity. A control experiment ruled out the possibility that tactile sensation associated with a keypress increased auditory temporal sensitivity. Taken together, these results demonstrate a unique reciprocal relationship between auditory time perception and motor mechanisms. As auditory perception facilitates precisely timed movements, generating action enhances auditory temporal sensitivity.
