词频、测验方式影响单字法定向遗忘的实验研究

An Experimental Research on Word Frequency and Test Type Affecting Word-Method-Directed Forgetting

单字法定向遗忘一直是记忆研究的热点。本文引入词频(高频词、低频词)和测验方式(内隐记忆测验、外显记忆测验)变量继续考察单字法定向遗忘,结果显示:(1)低频词语的内隐和外显记忆测验中都出现了显著的定向遗忘效应;(2)高频词语的外显记忆测验中出现了明显的定向遗忘效应,而在内隐记忆测验中却未发现定向遗忘效应;(3)单字法定向遗忘的机制是复述和提取抑制。

Word-method-directed forgetting has been a much discussed topic in the memory research field. The paper explored directed-forgetting by introducing word frequency（high frequency and low frequency） and memory test （implicit memory test and explicit memory test） variables. The results show： （1） in the low frequency dimension, directed forgetting affects implicit memory tests and explicit memory test （2） in the high frequency dimension, directed forgetting only affects explicit memory tests; （3） the mechanisms of word-method-directed-forgetting are rehearsal and retrieval inhibition.
