人类有一种独特的能力来协调他们的运动，以外部听觉刺激，如音乐诱导的脚打拍子或跳舞。这种行为目前引起了许多学科学者的注意。然而，对其最早的表现形式知之甚少。当前研究的目的是检查言语前婴儿是否会对音乐做出有节奏的行为。为此，我们进行了两个实验，其中我们测试了120名婴儿（5-24个月）。婴儿们被暴露在各种音乐和节奏刺激的片段中，包括等离子体鼓点。控制刺激由成人和婴儿指导的言语组成。通过多种方法评估婴儿的节奏运动，包括从视频摘录和创新的3D运动捕捉技术中手动编码。结果表明：（i）婴儿对音乐和其他节奏规则的声音比对语音进行更有节奏的运动;（ii）婴儿在一定程度上表现出克里思灵活性（例如，例如，在一个实施例中，更快的听觉克里思与更快的运动克里思相关）;以及（iii）与音乐的节奏协调程度与积极情感的表现呈正相关。这些发现暗示了对音乐和其他有节奏的声音做出反应的有节奏运动的倾向。
Humans have a unique ability to coordinate their motor movements to an external auditory stimulus, as inmusic-induced foot tapping or dancing. This behavior currently engages the attention of scholars across a number of disciplines. However, very little is known about its earliest manifestations. The aim of the current research was to examine whether preverbal infants engage in rhythmic behavior to music. To this end, we carried out two experiments in which we tested 120 infants (aged 5-24 months). Infants were exposed to various excerpts of musical and rhythmic stimuli, including isochronous drumbeats. Control stimuli consisted of adult-and infant-directed speech. Infants' rhythmic movements were assessed by multiple methods involving manual coding from video excerpts and innovative 3D motion-capture technology. The results show that (i) infants engage in significantly more rhythmic movement to music and other rhythmically regular sounds than to speech; (ii) infants exhibit tempo flexibility to some extent (e. g., faster auditory tempo is associated with faster movement tempo); and (iii) the degree of rhythmic coordination with music is positively related to displays of positive affect. The findings are suggestive of a predisposition for rhythmic movement in response to music and other metrically regular sounds.
