社会群体成员的行为通常是一般化的。重要的是，一个行动在实现外部目标方面的效率决定了行动的理解，它可能与社会群体有不同程度的社会相关性。因此，本研究探讨动作效率在动作概化中的作用。我们使用计算机动画来模拟由视觉动作线索或类别标签发起的社会群体中的动作，我们测量了识别与群体成员一致和不一致的动作之间的反应时间差异，没有明确的泛化要求。研究发现，在视觉引入和明确标记的社会群体中，当群体成员对外部对象采取无效率行为时，感知者对群体一致行为的识别速度快于群体不一致行为，这表明范例的常见无效率行为被推广到未知的群体内成员，从而促进了预期一致无效率行为的识别（实验1）。由于这种效应在移除社会群体线索时不存在，因此确定它是特定于社会群体的（实验2）。重要的是，当相同的动作被认为是对外部对象有效时（实验3），并且特定于由多个小组成员完成的动作而不是由一个小组成员重复两次的演示时，没有观察到这种泛化，这支持了基于群体的推理，并排除了低效率动作的记忆性增加导致相对于有效动作更泛化的可能性（实验4）。因此，一个行动的效率通过一个自发的和隐含的过程限制了该行动在社会群体成员中的泛化。这种受限的动作概括可能是由于低效的动作被表示为特定文化的常规形式。
Actions are usually generalized among social group members. Importantly, the efficiency of an action with respect to achieving an external target determines action understanding, and it may have different degrees of social relevance to social groups. Thus, this study explored the role of action efficiency in action generalization. We used computer animations to simulate actions in social groups initiated by visual action cues or category labels, and we measured differences in response times between identifying actions that were and were not consistent with group members, without explicit requirements regarding generalization. It was found that in both visually introduced and explicitly labeled social groups, when the group members acted inefficiently toward the external object, perceivers identified group-consistent actions faster than group-inconsistent actions, indicating that the exemplars' common inefficient actions are generalized to the unknown ingroup member, accordingly facilitating the identification of expected consistent inefficient action (Experiment 1). As this effect was not present when removing social group cues, it was determined to be specific to social groups (Experiment 2). Importantly, such generalization was not observed when the identical action was deemed efficient toward the external object (Experiment 3) and was specific to the demonstration of the action being completed by multiple group members rather than being repeated twice by one group member, supporting the group-based inference and ruling out the possibility of the increased memorability of inefficient actions leading to more generalization relative to efficient actions (Experiment 4). Therefore, the efficiency of an action bounds the generalization of the action across social group members through a process that is spontaneous and implicit. This constrained action generalization may be due to inefficient actions being represented as culture-specific conventional forms.
