Abstract: Memory performance is better in survival processing procedure than other processing procedures, which is named as survival advantage of memory. All the former studies were behavioral studies, whereby the researchers could not identify in which stage of memory process the advantage lies. The present study applies the Event-related-potentials(ERP)technology to explore in which stage(s)the survival advantage occurs, with using the “Indirect study-recognition”paradigm. Through comparing the processing of survival scenario, moving scenario and pleasantness scenario in encoding and retrieval stages, we found that the DM effect is more significant in the survival scenario than the moving and pleasantness scenarios during the time window of 500ms-700ms. The ON effect is more significant in the survival scenario than the moving and pleasantness scenarios during the time window of 400ms-600ms. These results indicated that there were both encoding advantage and retrieval advantage during the survival processing.

Key words: survival, memory, ERP, encoding advantage, retrieval advantage

摘要: 生存加工比控制条件有更好的记忆表现,产生稳定的记忆优势,这就是记忆生存优势。已有研究多采用行为学实验验证了此现象的存在,但没有确定该优势发生在记忆的何种阶段。本研究采用ERP技术和“间接学习-再认”实验范式,比较被试在生存情境、迁徙情境和愉悦判断中对词汇编码和提取过程的记忆加工,结果发现:在500-700ms时间段,生存情境的相继记忆效应显著大于迁徙情境和愉悦判断;在400-600ms时间段,生存情境的新旧效应显著大于迁徙情境和愉悦判断。表明生存加工具有编码和提取双重优势。
