社会排斥是一种令人痛苦的经历，可能会导致亲社会行为的减少。在这项功能磁共振成像研究中，我们检查了涉及社会排斥的神经网络以及随后在青少年发展过程中的公平考虑。来自3个年龄组（10-12岁、14-16岁和19-21岁）的参与者参与了研究并执行了两项任务；首先，参与者玩网络球来引发社会包容和排斥的感觉，然后是独裁者游戏，参与者被要求在自己和之前包容或排斥他们的玩家之间分配硬币。结果揭示了与社会排斥相关的区域网络，涉及内侧前额叶皮层 (mPFC)/腹侧前扣带皮层 (vACC)、膝下 ACC 和外侧 PFC，以及岛叶和背侧 ACC。尽管社会排斥给所有年龄段的人带来了强烈的痛苦，但 10-12 岁的孩子在排斥游戏中表现出膝下 ACC 的活动增加，这在之前的研究中与消极情感处理有关。独裁者游戏的结果显示，所有年龄组都有选择地通过提出较低的报价来惩罚排除者。这些提议与颞顶交界处 (TPJ)、颞上沟 (STS) 和外侧 PFC 的激活有关。年龄比较显示，成年人在向排除者提出要约时，岛叶和背侧 ACC 表现出额外的活动。根据最近关于涉及社会排斥和社交大脑区域发育的神经网络的发现对结果进行了讨论。 (C) 2011 Elsevier Inc. 保留所有权利。
Social exclusion is a distressing experience and can result in a reduction of prosocial behavior. In this fMRI study we examined the neural networks involved in social exclusion and subsequent fairness considerations across adolescent development. Participants from 3 age groups (10-12, 14-16 and 19-21 year olds) participated in the study and performed two tasks; first, participants played Cyberball to induce feelings of social inclusion and exclusion, followed by a Dictator game in which participants were asked to divide coins between themselves and the players who previously included or excluded them. Results revealed a network of regions associated with social exclusion, which involve the medial prefrontal cortex (mPFC)/ventral anterior cingulate cortex (vACC), subgenual ACC and the lateral PFC, as well as the insula and the dorsal ACC. Although social exclusion generated strong distress for all age groups, 10-12 year olds showed increased activity in the subgenual ACC in the exclusion game, which has been associated in previous studies with negative affective processing. Results of the Dictator game revealed that all age groups selectively punished the excluders by making lower offers. These offers were associated with activation in the temporoparietal junction (TPJ), superior temporal sulcus (STS) and the lateral PFC. Age comparisons revealed that adults showed additional activity in the insula and dorsal ACC when making offers to the excluders. The results are discussed in the light of recent findings on neural networks involved in social exclusion and the development of social brain regions. (C) 2011 Elsevier Inc. All rights reserved.
