Previous work using physiological measures has shown that socioeconomic status and social power both influence the degree to which people are attuned to the actions of others. However, it is unclear whether such effects on brain activity translate into behaviourally significant outcomes. Here, we examined differences in automatic imitation between individuals varying in SES and power from the local community population. The automatic imitation task involves participants making actions in response to a symbolic cue while simultaneously being exposed to an action that is incongruent or congruent with the cued response. Patterns of interference in reaction time and error rate reveal the extent to which a person is susceptible to influence from the actions of other-what we refer to as "the degree of social attunement". We found that individuals from low SES backgrounds and those in the low power priming group exhibited more interference than individuals from high SES backgrounds and those in the high power priming group. However, we did not observe an interaction between chronic status and the power group. We discuss our results in relation to broader behavioural patterns exhibited by individuals at varying levels of a social structure.
先前使用生理测量的研究表明，社会经济地位和社会权力都会影响人们对他人行为的适应程度。然而，目前尚不清楚这种对大脑活动的影响是否会转化为具有行为意义的结果。在这里，我们研究了来自当地社区人群中社会经济地位和权力不同的个体之间自动模仿的差异。自动模仿任务涉及参与者在对符号提示做出反应的同时，同时暴露于与提示反应不一致或一致的动作。反应时和错误率的干扰模式揭示了一个人对他人行为影响的程度——我们称之为“社会协调程度”。我们发现，来自低社会经济地位背景的个体和处于低权力启动组的个体比来自高社会经济地位背景的个体和处于高权力启动组的个体表现出更多的干扰。然而，我们没有观察到慢性状态和权力群体之间的相互作用。我们根据不同社会结构层次的个体表现出的更广泛的行为模式来讨论我们的结果。
