摘要： 通过事件相关电位（ERPs）记录，探讨了深、浅2种加工与记忆编码的相互关系。研究结果表明，（1）在深、浅两种加工条件下，首次使用汉字材料，获得了ERP相继记忆效应(Dm)，随后再认正确的ERPs比随后再认不正确的ERPs有更大的晚正成分。（2）深加工的Dm效应始于 N2波的前支（230~ 280 ms）和N2波之后（395~ 800 ms）；而浅加工的Dm效应发生在 345~490 ms之间。深、浅加工的Dm效应涉及不同的脑区，这一结果支持深、浅两种加工的Dm效应可能是分离的结论

Abstract: Event-related potentials (ERPs) were recorded to investigate the relationship between deep/shallow processing and memory encoding. Three major results were: (1) Under both processings of Chinese materials, the subsequent memory effects (Dm) were obtained. A late positive ERP elicited by words later recognized was larger than that elicited by words later forgotten. (2) The Dm effect was different between the two processings. The Dm effect for deep processing began at the front branch of N2 wave (230—280 ms), and more obvious held behind N2 from 395ms to 800ms. The Dm effect for shallow processing was obtained only from 345ms to 490ms. In addition, the Dm for deep processing was observed over frontal and fronto-central areas of scalps but over parietal and occipital areas for the shallow processing. Such results support the possibility that deep and shallow processing Dm effect may diverge. (3) The Dm effect was different from ERP differences between two processings. Such results support the speciality of Dm effect in memory encoding
