Social exclusion refers to the experience of rejection by one or more people during a social event and can induce pain-related sensations. Cyberball, a computer program, is one of the most common tools for analyzing social exclusion. Regions of the brain that underlie social pain include networks linked to the dorsal lateral prefrontal cortex (DLPFC). Specifically, self-directed negative socially induced exclusion is associated with changes in DLPFC activity. Direct manipulation of this area may provide a better understanding of how the DLPFC can influence the perception of social exclusion and determine a causal role of the DLPFC. Transcranial magnetic stimulation (TMS) was applied to both the left and right DLPFC to gauge different reactions to the Cyberball experience. It was found that there were elevated exclusion indices following right DLPFC rTMS; participants consistently felt more excluded when the right DLPFC was excited. This may relate to greater feelings of social pain when the right DLPFC is manipulated. These data demonstrate that direct manipulation of the DLPFC results in changes in responses to social exclusion.
社会排斥是指在社交活动中被一个或多个人拒绝的经历,并且会引发与疼痛相关的感觉。Cyberball(一款电脑程序)是分析社会排斥最常用的工具之一。构成社会疼痛基础的大脑区域包括与背外侧前额叶皮层(DLPFC)相连的神经网络。具体而言,自我导向的负面社会诱导排斥与DLPFC活动的变化有关。直接操纵该区域可能有助于更好地理解DLPFC如何影响社会排斥的感知,并确定DLPFC的因果作用。经颅磁刺激(TMS)被应用于左右DLPFC,以评估对Cyberball体验的不同反应。研究发现,右侧DLPFC重复经颅磁刺激(rTMS)后排斥指数升高;当右侧DLPFC受到刺激时,参与者持续感到被更多地排斥。这可能与右侧DLPFC受到操纵时更强烈的社会疼痛感受有关。这些数据表明,直接操纵DLPFC会导致对社会排斥的反应发生变化。
