152. 乐观与未来思维的神经表征

from 知为谁 · host 知为谁

本研究出自《美国国家科学院院刊》,探讨了乐观个体大脑中未来思考的神经表征。该研究通过功能性磁共振成像(fMRI)实验,检验了乐观者在想象未来事件时是否表现出相似的神经活动模式。文章运用跨主体表征相似性分析(IS-RSA)和个体差异多维尺度分析(INDSCAL)两种方法,发现高度乐观的个体在内侧前额叶皮层(MPFC)的神经活动表现出更高的相似性。此外,研究还发现乐观者在想象积极事件时,其神经表征与消极事件的区分度更高,表明乐观情绪会促进对正面与负面未来事件的心理区分。这些发现为理解乐观对认知和神经机制的影响提供了重要见解。内容来源:https://www.pnas.org/doi/10.1073/pnas.2511101122
