创造性认知重评在情绪调节中的迁移效应及其神经基础

The neural mechanism and transfer effect of creative cognitive reappraisal in negative emotion regulation

认知重评在负性情绪调节中发挥着重要的作用。针对传统认知重评重构程度不够高、调节效果不明显的问题,研究团队在先前的工作中提出了一种使消极情绪“转负为正”的高效情绪调节方法,即创造性认知重评,这种调节策略伴随着大脑海马的新颖联结形成和杏仁核的积极情绪唤醒。然而这些工作采用“指导式”的重评更像是对重评解读的“理解”而非主动的情绪调节;鉴于主动情绪调节的产生难度较大,造成创造性认知重评在实际应用上的两难困境。基于此,本项目拟指导受试者进行创造性认知重评的学习,通过学习将这种策略迁移并且应用到生活中的负性情绪调节事件中。具体研究内容包括:(1)行为学上,探索创造性认知重评在大学生群体和青少年群体负性情绪调节中的迁移效应;(2)影像学上,探索创造性认知重评迁移前后在脑认知表征模式上的变化。本项目是对已有工作基础的延伸和拓展,为验证和推动创造性认知重评成为一种可学、可用、高效的情绪调节策略奠定理论基础。

Cognitive reappraisal plays an important role in regulating negative emotions.However,traditional cognitive reappraisal has some issues,such as a lower reconstruction degree and a lower emotion regulation effect.Considering these issues,we propose an effective emotion regulation strategy called creative cognitive reappraisal,which refers to a dramatic shift from negative to positive emotions and a long-lasting regulatory effect.According to imaging results,creative cognitive reappraisal was associated with the formation of a novel association in the hippocampus and positive emotional arousal in the amygdala.However,the guided reappraisal used in this work was more akin to an understanding of reappraisal interpretation than active emotion regulation,which has lower ecological validity.Furthermore,it is difficult to generate high creative reappraisal on one’s own,making the application of creative cognitive reappraisal challenging.Thus,the goal of this project is to teach participants how to learn the method of creative cognitive reappraisal and then transfer and apply this strategy to specific negative emotion regulation in daily life.The specific research contents are as follows:1)exploring the transfer effect of creative cognitive reappraisal in negative emotion regulation of college students and adolescents;2)investigating changes in brain activation and representation patterns before and after creative cognitive reappraisal transfer,and the similarities and differences in the neural mechanisms of creative cognitive reappraisal transfer between adolescents and adults.This project is an extension and expansion of the applicant's existing work,and it would establish a theoretical foundation for verifying and promoting creative cognitive reappraisal as a learnable,usable and efficient emotional regulation strategy.
