Abstract: Episodic memory is a uniquely oriented-past neurocognitive system, which consists of three central components-self, autonoetic awareness, and sense of subjective time, and which makes mental time travel possible. Episodic retrieval, different from other memory systems, accompanies autonoetic awareness. Additionally, a large number of studies have confirmed the hemispheric encoding/retrieval asymmetry model (HERA model): left prefrontal cortex is differentially more involved than right in encoding information into episodic memory, whereas right prefrontal cortex is differentially more involved than left in episodic memory retrieval. Since episodic memory is closely relative to self and consciousness, studies on episodic memory will reveal the relationship between memory and consciousness.

Key words: episodic memory, self, autonoetic awareness, sense of subjective time

摘要: 情景记忆是由自我、自我觉知和主观时间组成的惟一指向过去的认知神经系统,它使心理时间旅行成为可能。与其他记忆系统相比,情景记忆的独特性不仅表现在提取信息时伴随着自我觉知,指向过去,而且情景记忆还有其独特的脑定位,许多研究支持情景记忆的编码主要与大脑的左半球有关,提取主要与右半球有关。由于情景记忆与自我、意识有密切的关系,情景记忆的研究必将极大地推动记忆与意识的研究。
