概括

大脑连接模式的个体差异预测第三方干预行为,区分帮助受害者和惩罚事者. 特定大脑网络中的静止状态功能连接 (rs-FC) 是这些恢复正义行动的基础.

科学领域:

神经科学是一个神经科学.
社会心理学社会心理学
决策科学决策科学决策科学

背景情况:

个人经常作为第三方干预维护正义,要么惩罚罪犯,要么帮助受害者.
了解这些干预措施中个体差异的神经基础,特别是帮助和惩罚之间的区别,仍然是有限的.

研究的目的:

为了研究本质大脑连接和第三方干预倾向的个体差异之间的关系.
探索这些大脑连接模式如何与帮助与惩罚行为有不同的关系.

主要方法:

利用一种新的行为范式与静止状态功能磁共振成像 (fMRI) 结合.
使用跨主体表示相似性分析 (IS-RSA) 来分析静止状态功能连接 (rs-FC).
专注于涉及第三方惩罚 (TPP) 的关键大脑网络:突出,中央执行和默认模式网络.

主要成果:

在突出,中央执行和默认模式网络内rs-FC的个别差异与一般的第三方干预倾向相关.
右背侧前额叶皮层 (dlPFC) 和右关节 (TPJ) 的连接性与帮助倾向更相关.
背中介前额叶皮层 (dmPFC) 的连接性与惩罚倾向更为相关.
这些地区的 rs-FC 预测了个体间的干预倾向.

结论:

休息时大脑网络的共同和独特的角色有助于恢复正义干预的个体差异.
神经连接模式提供了关于帮助受害者与惩罚事者的倾向的见解.
这项研究促进了我们对亲社会行为和与正义有关的行为的神经支的理解.

关键词:

Bystander Effect

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Deindividuation

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.
