Acting in synchrony is a fundamental part of many social interactions and can have pro-social consequences. Explanations for this relationship were investigated here using implicit measures of imitation (automatic imitation task) and memory (preference overlap task). In Study 1, participants performed an intentional synchronisation task where they moved sliders in or out of time with another person while a third person observed. Those who had moved in synchrony showed a stronger tendency to imitate their partner's actions than those who had moved in a non-synchronous way. Similarly, coordinated partners were also more likely to share object preferences. Results also showed that rather than memory blurring between co-actors, participants had improved memories for the self. Study 2 exchanged intentional for incidental coordination (coordinating with a synchronous metronome). None of the findings from Study 1 replicated when synchronisation was incidental rather than intentional, suggesting that having a shared goal may be critical for triggering effects of synchronisation on imitation tendencies and memory. Together these findings favour explanations related to changes in social categorisation over representational overlap between co-actors.
同步行为是许多社交互动的基本组成部分，并且可能具有亲社会的后果。本研究使用模仿的内隐测量（自动模仿任务）和记忆（偏好重叠任务）来探究这种关系的解释。在研究 1 中，参与者进行了一项有意的同步任务，在该任务中，他们与另一个人一起将滑块向内或向外移动，而第三个人则在观察。与以非同步方式移动的参与者相比，以同步方式移动的参与者更倾向于模仿其伴侣的动作。同样，协调的伙伴也更有可能共享对象偏好。结果还表明，参与者对自身的记忆并没有因为共同作用者之间的记忆模糊而受到影响。在研究 2 中，用偶然的协调（与同步节拍器协调）取代了有意的协调。当同步是偶然的而不是有意的时，研究 1 中的所有发现都没有得到复制，这表明共同目标的存在可能是触发同步对模仿倾向和记忆影响的关键。这些发现都支持了与社会分类变化相关的解释，而不是共同作用者之间的代表性重叠。
