情景预见的认知机制:情景建构与语义支撑

Cognitive and Neural Mechanisms of Episodic Foresight:Scene Construction and Semantic Scaffolding

情景预见是指个体将自我投射到特定的时间和地点预先经历未来可能发生的事件,对其认知神经机制的探讨是该领域的热点之一。主要理论假说包括:情景建构、自我投射和情景-建构-模拟假说。经过比较和整合之后,我们提出了在情景预见中,情景建构和语义支撑协同作用的认知机制,并相应地提供了来自神经心理学和神经成像的研究证据。未来研究可以继续发掘孤独症等特殊群体的研究潜力,同时借鉴和整合默认网络的研究,进一步澄清情景预见的认知神经机制。

Episodic foresight refers to the ability that individuals project themselves into a particular time and place to pre-experience a possible event in the future. The cognitive and neural mechanism underlying episodic foresight is one of hot issues in this domain. Relevant theories mainly include scene-construction, self-projection, and scene-construction- simulation hypotheses. By comparing and integrating these hypotheses, we proposed that scene construction and semantic scaffolding collaboratively contributed to the process of episodic foresight. Then we provided evidence with neuropsychologi- cal and neuroimaging studies. In the future, the cognitive and neural mechanism underlying episodic foresight could be elu- cidated from the perspective of special groups（such as autism spectrum disorder）, incorporating the progress from default network.
