舞蹈、歌唱和音乐制作等音乐行为需要跟随有节奏的节拍的能力，可以促进高水平的人际协调。这种协调与增加群体凝聚力和群体成员之间的社会联系有关。之前，我们证明了这种联系甚至影响了14个月大婴儿的社会行为。与随着音乐同步弹跳相比，婴儿在同步弹跳后更有可能对成人实验者表现出乐于助人的态度。本实验的目的是确定是否人际同步作为一个线索，14个月大的孩子直接他们的亲社会行为与他们经历了同步运动的特定个人，或是否作为一个社会总理，增加亲社会行为的一般。与先前的结果一致，婴儿在与实验者同步运动与异步运动之后更有可能帮助这个人。此外，这种操纵并没有影响婴儿的行为对一个中立的陌生人，谁是不参与任何运动的经验。这表明，同步弹跳作为一个社会线索，指导亲社会。这些结果对音乐参与和节奏同步如何影响早期发展中的社会行为具有重要意义。
Musical behaviours such as dancing, singing and music production, which require the ability to entrain to a rhythmic beat, encourage high levels of interpersonal coordination. Such coordination has been associated with increased group cohesion and social bonding between group members. Previously, we demonstrated that this association influences even the social behaviour of 14-month-old infants. Infants were significantly more likely to display helpfulness towards an adult experimenter following synchronous bouncing compared with asynchronous bouncing to music. The present experiment was designed to determine whether interpersonal synchrony acts as a cue for 14-month-olds to direct their prosocial behaviours to specific individuals with whom they have experienced synchronous movement, or whether it acts as a social prime, increasing prosocial behaviour in general. Consistent with the previous results, infants were significantly more likely to help an experimenter following synchronous versus asynchronous movement with this person. Furthermore, this manipulation did not affect infant's behaviour towards a neutral stranger, who was not involved in any movement experience. This indicates that synchronous bouncing acts as a social cue for directing prosociality. These results have implications for how musical engagement and rhythmic synchrony affect social behaviour very early in development.
