情节式未来思考的认知神经机制

摘要

情节式未来思考（ episodic future thinking/thought， EFT）是将自我投射到未来以提前经历某事件的能力。回忆过去和想象未来在很大程度上依赖共同的认知过程和脑区。 EFT的认知机制主要关注如何构建EFT，如何把回忆过去和想象未来相联系，以及EFT的现象学特征认知差异。 EFT的神经机制主要探讨想象未来是否具有专属脑区，想象未来和回忆过去的脑区差异，回忆过去和想象未来是否共享大脑系统。从记忆、海马回对EFT的作用以及EFT与时间折扣的关系提出未来研究的方向。%Episodic future thinking is a projection of the self into the future to pre-experience an e-vent. Remembering the past and imagining the future both relies heavily on the common cognitive process and encephalic zone. Cognitive mechanism focuses on how to construct episodic future thinking, how to relate remembering the past to imagine the future, and cognitive differences on phenomenological fea-tures. Neural mechanism primarily explores whether specific brain system supports episodic future think-ing, neural differences on remembering the past and imagining the future, and whether remembering the past and imagining the future share the common brain system. The future directions should highlight the role of memory, aging and hippocampus on episodic future thinking, and the relationship between episod-ic future thinking and temporal discounting.
