记忆巩固效力研究述评

A review on the efficacy of memory consolidation

睡眠的记忆巩固在多大程度上取决于学习材料的类型、学习与提取测验的类型以及睡眠的不同特征?弱编码联系、外显编码的记忆相对于强编码联系、内隐编码的记忆提高得更多;慢波睡眠巩固陈述性记忆而快速眼动睡眠巩固程序性和情绪性记忆;陈述性记忆的提高来自相当短的睡眠时间,程序性记忆的提高似乎更多地取决于学习后当天的睡眠时间长度。

What extent memory consolidation during sleep depends on the type of learning materials , type of learning and re-trieval test and different features of sleep .The enhancement is greater for weakly than strongly encoded associations and more consistent for explicitly than implicitly encoded memories .Slow wave sleep particularly enhances declarative memories whereas rapid eye movement sleep preferentially supports procedural and emotional memory aspects .Declarative memory pro？ ts come from rather short sleep periods .Procedural memory pro？ ts seem more dose-dependent on the amount of sleep following the day after learning .
