概括
基底侧桃体 (BLA) 通过调整基于社会距离的慷慨来帮助调节亲社会行为. 对BLA的损害导致整体慷慨减少和更的社会折扣.
科学领域:
- 神经科学是一个神经科学.
- 社会认知是指社会认知.
- 行为经济学是一种行为经济学.
背景情况:
- 底侧桃体 (BLA) 与社会偏好有关.
- 它在亲社会决策中的确切作用,特别是在社会距离方面,尚未完全理解.
研究的目的:
- 调查人类BLA在校准亲社会行为的作用.
- 测试BLA微调基于社会距离的亲社会性的假设.
主要方法:
- 使用修改过的独裁者游戏,参与者患有乌尔巴赫-维特病 (UWD) 和双边BLA损伤.
- 将UWD参与者的亲社会选择与不同社会距离的健康对照进行了比较.
主要成果:
- 与对照组相比,UWD参与者表现出较低的整体慷慨.
- UWD参与者表现出更的社会折扣,随着社会距离的增加,分享意愿下降得更快.
- 这些差异不能归因于同理心,个性或社交网络规模.
结论:
- 在社会折扣中,BLA对于解决自我利益和利他主义之间的冲突至关重要.
- BLA功能对于基于模型的社会认知至关重要,可以根据社会情感距离对亲社会行为进行校准.
