While synchronized movement has been shown to increase liking and feelings of togetherness between people, we investigated whether collective speaking in time would change the way that larger groups played a video game together. Anthropologists have speculated that the function of interpersonal coordination in dance, chants, and singing is not just to produce warm, affiliative feelings, but also to improve group action. The group that chants and dances together hunts well together. Direct evidence for this is sparse, as research so far has mainly studied pairs, the effects of coordinated physical movement, and measured cooperation and affiliative decisions. In our experiment, large groups of people were given response handsets to play a computer game together, in which only joint coordinative efforts lead to success. Before playing, the synchrony of their verbal behavior was manipulated. After the game, we measured group members' affiliation toward their group, their performance on a memory task, and the way in which they played the group action task. We found that verbal synchrony in large groups produced affiliation, enhanced memory performance, and increased group members' coordinative efforts. Our evidence suggests that the effects of synchrony are stable across modalities, can be generalized to larger groups and have consequences for action coordination.
虽然同步运动会增加人们之间的喜爱程度和亲密感，但我们研究了同步集体发声是否会改变大群体一起玩电子游戏的方式。人类学家推测，舞蹈、圣歌和歌唱中人际协调的功能不仅是产生温暖、亲密的感觉，还能改善群体行动。一起吟唱和跳舞的群体一起打猎也很出色。对此的直接证据很少，因为迄今为止的研究主要集中在两人组、协调身体运动的影响以及对合作和亲密决策的测量上。在我们的实验中，给大群体的人发放应答手机，让他们一起玩电脑游戏，在这个游戏中只有共同的协调努力才能成功。在游戏前，操纵他们言语行为的同步性。游戏结束后，我们测量了小组成员对自己小组的归属感、他们在记忆任务中的表现以及他们完成群体行动任务的方式。我们发现，大群体中的言语同步产生了归属感，提高了记忆表现，并增加了小组成员的协调努力。我们的证据表明，同步效应在不同模态中是稳定的，可以推广到大群体中，并且对行动协调有影响。
