摘要
再认记忆的认知过程是个体判断刺激是否在先前遇到过的一种能力,包括两种不同的形式:回忆和熟悉。多年来,其一直是研究的热点问题,尤其是对婴儿再认记忆过程的研究。事件相关电位是一种无创性的测查,能够在无明显行为表现的情况下记录婴儿对外部事件引发的脑电变化,且具有高时间分辨率,因此越来越广泛地被应用于婴儿认知发育的研究。事件相关电位的晚期成分被认为能够反应再认记忆的认知过程:晚期长潜伏期正性慢波与部分编码刺激的记忆更新过程有关;晚期长潜伏期负性慢波反应了个体对新奇刺激的探测过程。该文旨在对事件相关电位在婴儿再认记忆研究中的应用加以综述。
Recognition memory is ability of an individual to judge whether a stimulus has encountered previously, and it consists of two components： recollection and familiarity. It is a hot spot of study in recent years, especially study on recognition memory of infants. Event- related potential （ERP） is a non-invasive examination, it can record changes in brain potentials evoked by external events in absence of distinct external behaviors, and has a high temporal resolution. So, it is widely used in researches on cognitive development of infants. Late components of ERP is considered to reflect cognitive process of recognition memory： positive slow wave in late long latency is believed to be related to memory renewing process for partially encoded stimuli and negative slow wave in late long latency reflects processing of individual for novel stimuli. This article reviewed application of eventrelated potential in study on recognition memory of infants.
