Joint action theorizing implies that any coordinated behaviour that induces co‐representation with a partner should increase social identification, especially when the associated actions require a high degree of coordination and are experienced as being performed effectively. The current research provides a first test of this new theoretical prediction for complementary (rather than synchronous) joint actions. In each of two pre‐registered experiments establishing a novel paradigm, participants performed a digital joystick task with a joint performance goal with three different partners. The task varied in coordination requirements across partners. In Experiment 1, results showed that when task segments were discrete between partners, they identified less as a group than when they had to coordinate their behaviour. Surprisingly, although constant coordination increased co‐representation relative to intermittent coordination, it did not correspondingly increase social identification. However, performance correlated positively with identification; as performance was worse when participants had to coordinate, this may explain the results. Experiment 2 showed that performance is causally linked to identification when coordination is necessary. Taken together, our results suggest that experiencing effective coordination leads to greater social identification. In general, paradigms capable of examining the perceptual and motor aspects of collective behaviour may offer a new perspective on social identification in general and the performance‐identification link in particular.

运动协调诱导社会认同——研究群体绩效-身份联系的新范式


联合行动理论化意味着，任何引起与伙伴共同代表的协调行为都应该增加社会认同感，特别是当相关行动需要高度协调并且体验到被有效执行时。目前的研究为这种互补（而不是同步）联合行动的新理论预测提供了第一次测试。在建立新范式的两个预先注册的实验中，参与者与三个不同的伙伴执行了一项具有联合性能目标的数字操纵杆任务。不同合作伙伴的协调要求各不相同。在实验 1 中，结果表明，当任务细分在合作伙伴之间离散时，他们作为一个群体的识别比他们必须协调自己的行为时要少。令人惊讶的是，尽管相对于间歇性协调，持续协调增加了共同表征，但它并没有相应地增加社会认同。然而，性能与识别呈正相关;由于当参与者必须协调时表现更差，这可能解释了结果。实验 2 表明，当需要协调时，表现与识别有因果关系。综上所述，我们的结果表明，体验有效的协调会带来更大的社会认同感。一般来说，能够研究集体行为的感知和运动方面的范式可能会为一般的社会认同，特别是绩效-认同联系提供新的视角。
