ABSTRACT

We examined whether the perceived similarity between two individuals can shape social attention shifts during a joint-action task. Initially, a confederate was described to a naïve participant through a personality profile in order to manipulate the degree of attitude similarity between them, and they later performed a joint-action task involving alternated aiming movements towards peripheral targets. This task is known to elicit two forms of Inhibition of Return (IOR), namely longer latencies when responding to a target previously reached by either oneself (individual IOR) or by the partner (social IOR) as compared to a previously-unreached target. Here, both IOR effects emerged but – unlike previous studies – social IOR was greater than individual IOR. Interestingly, such magnified social IOR occurred regardless of the degree of attitude similarity between participants. This seems to suggest that social knowledge about others can lead to a generalized impact on social attention during real interactions with them.

摘要

我们检查了两个人之间感知到的相似性是否可以在联合行动任务期间影响社会注意力的转变。最初，通过个性特征向天真的参与者描述了一个同盟，以操纵他们之间的态度相似程度，然后他们执行了一项联合行动任务，涉及交替瞄准外围目标的运动。众所周知，这项任务会引发两种形式的返回抑制 (IOR)，即与先前未达到的目标相比，响应自己（个人 IOR）或合作伙伴（社交 IOR）先前达到的目标时的延迟更长。在这里，两种 IOR 效应都出现了，但与之前的研究不同的是，社会 IOR 大于个人 IOR。有趣的是，无论参与者之间的态度相似程度如何，这种放大的社会 IOR 都会发生。这似乎表明，在与他人的真实互动中，关于他人的社会知识会对社会注意力产生普遍影响。
