人类发展了听觉-运动的相互作用，通过身体运动产生各种有节奏的声音，这些声音通常是用工具产生和放大的，比如击鼓。声音的扩展生产使我们能够表达广泛的情感，伴随着生理变化。根据以前的研究，即使是年幼的婴儿也会对听觉反馈做出反应。然而，他们的展览生理适应的出现，运动的互动是不清楚的。我们研究了3个月大婴儿的运动和心脏变化与听觉反馈的自发肢体运动。结果表明，婴儿增加了肢体运动的频率诱导听觉反馈，而他们表现出更有规律的肢体运动的节奏。此外，与肢体运动相关的心率增加在听觉反馈的定时之后立即被抑制，这可能反映了对听觉刺激的持续注意。然后，通过听觉-运动体验，心率增加甚至在听觉反馈之前被抑制，导致心率增加的峰值强度被抑制。这些研究结果表明，年幼的婴儿调节心血管系统以及肢体运动的预期听觉反馈。与运动和注意力变化相关的预期调节可能有助于减少大脑-运动相互作用中的心血管应激，并为产生有节奏的声音的更复杂的目标导向行为提供发展基础。
Humans develop auditory-motor interaction to produce a variety of rhythmic sounds using body movements, which are often produced and amplified with tools, such as drumming. The extended production of sounds allows us to express a wide range of emotions, accompanied by physiological changes. According to previous studies, even young infants enhance movements in response to auditory feedback. However, their exhibition of physiological adaptation on the emergence of auditory-motor interaction is unclear. We investigated the movement and cardiac changes associated with auditory feedback to spontaneous limb movements in 3-month-old infants. The results showed that infants increased the frequency of limb movements inducing auditory feedback, while they exhibited a more regular rhythm of the limb movements. Furthermore, heart rate increase associated with the limb movement was first inhibited immediately after the timing of the auditory feedback, which may reflect sustained attention to the auditory stimuli. Then, through auditory-motor experience, the heart rate increase was inhibited even prior to the auditory feedback, leading to suppression of the peak intensity of the heart rate increase. These findings suggest that young infants regulate the cardiovascular system as well as limb movements in anticipation of the auditory feedback. The anticipatory regulation associated with movement and attentional changes may contribute to reduced cardiovascular stress in auditory-motor interaction, and provide a developmental basis for more sophisticated goal-directed behavior of producing rhythmic sounds.
