概括
社会排斥不那么令人痛苦,当被认为是由一个人决定时,它会引起较弱的大脑反应,与群体排斥不同. 这挑战了以前关于社会排斥处理的研究结果.
科学领域:
- 社会心理学 社会心理学
- 认知神经科学是一种认知神经科学.
- 神经科学是一个神经科学.
背景情况:
- 社会排斥显著影响归属感,并引起负面的情感反应.
- 与事件相关的潜力 (ERP),特别是P3效应,表明将排斥处理为违反预期的社会参与.
- 网络球模式是研究社会排斥的主要方法,模拟一个投球游戏.
研究的目的:
- 通过引入一个新的范式,挑战现有的关于社会排斥的发现,Cyberband.
- 研究如何在一个单一的决策者 (指挥家) 的影响下,在一个管弦乐团环境中经历的排斥会影响情感反应和大脑活动.
- 为了比较排斥单独表演与联合行动的影响.
主要方法:
- 介绍了Cyberband范式,模拟了乐队环境中的排斥.
- 实验1:减少指向一个人的导体线索 (单独排除).
- 实验2:减少参与联合行动 (tutti) 与双向行动 (duets) 的参与.
主要成果:
- 与Cyberball发现相比,单独排除在Cyberband中减少了自我报告的归属威胁和P3效应.
- 从联合行动 (tutti) 中排除增强了P3效应,而从二级行动 (duets) 中排除却没有.
- 减少参与影响了早期的正面ERP积极性 (P2),表明暗示突出性的变化.
结论:
- 归因于单一决策者的排斥被体验为不那么痛苦,并引起不同的神经特征,而不是排斥在小组环境中.
- 网络球设置关于排除处理的发现可能不适用于涉及单一权威人物的情况.
- 从联合行动中排除似乎是ERP签署违反预期的更强有力的触发因素,而不是从单个绩效线索中排除.

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Social identity constitutes a significant aspect of an individual’s self-concept, shaped by membership in various social groups, including gender, nationality, ethnicity, sexual orientation, and political affiliation. Individuals associate specific traits with particular social groups, leading to internalization of these traits. For example, musicians are often perceived as creative, while women are frequently associated with nurturing tendencies. Once individuals identify with a...

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...
