背景:多年来的研究已经探索了社会规范对运动行为的影响。然而,关于个人在他或她的社交网络中的角色(中央或外围)是否鲜为人知,这与社交技能有关,可能会改变他或她对锻炼行为的规范性影响的敏感性。为此,记录事件相关电位(ERP),以检查网络中心性对规范社会影响的潜在认知机制。
方法:我们通过将参与者分配到运动支持小组来操纵网络中心性,小组成员是他们提名的朋友(高中心)或非提名的同学(低中心)。参与者被要求评估他们参与各种练习的意愿,在查看不同的组评级(同行影响)或不查看(无影响)之后。
结果:同伴影响引起更大的负反馈相关负波(FRN),这与自动社会冲突检测有关,和一个更大的正向P3波,这与随后的合规行为变化有关。然而,对FRN的影响,不是P3,仅在高中心组中观察到。
结论:我们的结果强调了网络中心性在编码自我群体运动态度差异中的重要作用,而不是在运动态度调整的决策中。应在更广泛的社会环境框架中考虑旨在促进运动行为的干预措施。
The influence of social norms on exercise behaviors has been explored in studies over the years. However, little is known about whether an individual\'s role (central or peripheral) in his or her social network, which is associated with social skills, could shift his or her susceptibility to normative effects on exercise behaviors. To that end, event-related potentials (ERPs) were recorded to examine the underlying cognitive mechanism of the effects of network centrality on normative social influence.
We manipulated network centrality by assigning participants to exercise support groups, with group members who were their nominated friends (high centrality) or nonnominated classmates (low centrality). Participants were asked to evaluate their willingness to engage in various exercises, after viewing discrepant group ratings (peer influence) or not viewing (no-influence).
Peer influence evoked a larger negative-going feedback-related negativity (
FRN) wave, which was linked to automatic social conflict detection, and a larger positive-going P3 wave, which was linked to subsequent conformity behavioral changes. However, effects on the
FRN, not the P3, were observed only in the high-centrality group.
Our results highlight the important roles of network centrality in encoding self-group exercise attitude discrepancy rather than in decision-making regarding exercise attitude adjustments. Interventions aimed at promoting exercise behaviors should be considered in a broader social environmental framework.
