People often coordinate actions with others, requiring an adjustable amount of self-other integration between actor's and co-actor's actions. Previous research suggests that such self-other integration (indexed by the joint Simon effect) is enhanced by agent similarity of the co-actor (e.g., high in intentionality). In this study, we aimed to extend this line of research by testing whether experiencing agency over a co-actor's actions (vicarious agency) and/or action prediction strengthens the joint Simon effect. For this purpose, we manipulated experienced agency by varying the experienced control over a co-actor's actions (Experiment 1), and action prediction regarding the co-actor's actions (Experiment 2). Vicarious agency could effectively be induced, but did not modulate the size of the joint Simon effect. The joint Simon effect was decreased when the co-actor's actions were unpredictable (vs. predictable) during joint task performance. These findings suggest social agency can be induced and effectively measured in joint action. Action prediction can act as an effective agency cue modulating the amount of self-other integration in joint action.
人们经常与他人协调行动，这需要在演员和共同演员的行动之间进行可调节的自我-他人整合。先前的研究表明，这种自我-他人的整合（以共同西蒙效应为指标）会因共同演员的代理人相似性（例如，意图高）而增强。在这项研究中，我们旨在通过测试体验共同演员的行动（代理体验）和/或行动预测是否会增强共同西蒙效应来扩展这一研究思路。为此，我们通过改变对共同演员的行动的体验控制（实验 1）和对共同演员的行动的行动预测（实验 2）来操纵体验代理。可以有效地诱导代理体验，但不会调节共同西蒙效应的大小。当共同演员的行动在联合任务执行期间不可预测（相对于可预测）时，共同西蒙效应会降低。这些发现表明，在联合行动中可以诱导和有效地测量社会代理。行动预测可以作为有效的代理线索，调节联合行动中自我-他人整合的程度。
