概括

个人不喜欢对自己和他人不公平,激活类似的大脑区域,如前脑岛 (AI) 和背部前带状皮层 (dACC). 然而,对自己的不公平显示出更强烈的激活,表明与对他人的不公平相比,更大的厌恶和情绪反应.

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

背景情况:

个人表现出对不公平的厌恶,无论是亲自经历的还是观察到的.
现有的研究缺乏关于神经对自我与他人指导的不公平反应的相似性和差异的共识.
关于公平性的神经成像研究提出了不一致的发现,需要进行全面的审查.

研究的目的:

系统地审查和综合对自我和他人不公平的神经相关的发现.
阐明不同类型的不公平行为的评估和反应背后的独特和共同的神经机制.
提供神经生物学证据支持不平等厌恶和公平的模型.

主要方法:

对现有的神经成像研究进行了元分析,调查对不公平行为的反应.
比较神经激活模式与不公平的自我与不公平的他人.
检查了参与处理不公平行为的评估和响应阶段的大脑区域.

主要成果:

自我和他人导向的不公平都激活了情感和冲突相关的区域 (前胰岛[AI],背前带膜皮层/补充运动区域[dACC/SMA]).
对自我不公平在这些地区引起了更强烈的激活,这表明了更大的厌恶反应.
在评估过程中出现了不同的神经模式 (自我:AI,dACC,右脊侧前额叶皮层[DLPFC];其他:下侧顶叶叶-顶叶结口[IPL-TPJ]) 和响应 (自我:左侧AI,条纹体;其他:左侧DLPFC,丘脑),突出了自动/情绪与认知控制过程.

结论:

共同的神经机制是处理自我和其他人指导的不公平的基础,主要涉及情感和冲突监控系统.
在评估和响应过程中,不同的神经路径被参与,反映了对自我不公平的自动,情感反应和对其他不公平的认知控制.
研究结果支持不平等厌恶模型,并提供神经生物学背景下对公平性的神经证据.

关键词:

评估和响应的评估和响应.这就是FMRI.进行元分析分析.自我和其他人.这是不公平的不公平.

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Fundamental Attribution Error

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...
