复述、提取抑制与有意遗忘的实验研究

有意遗忘是关于记忆研究的另一种实验范式，对于在实验中出现的要求遗忘的学习项目的记忆成绩差于要求记忆的项目的结果，目前主人存在着两种理论解释：基于编码的理论和基于提取抑制的理论。该实验运用单字提示方式，采用控制较为严密的补笔测验方法和加入所谓的“无关项”，对有意遗忘的心理过程进行进一步的探讨，实验表明：在单了提示方式下，被试在进行有意遗忘的过程中，既对记忆项进行了有意的复述又对遗忘项产生了提取抑制。

ROLES OF REHEARSAL AND RETRIEVAL INHIBITION ON INTENTIONAL FORGETTING

In the intentional forgetting paradigm,after material had been presented for study,subjects were instructed to remember some of them and forget the remainder.Considerabe research showed that remember-cued items were recalled more thanforget-cued items. There were mainly two theories to explain the result:encoding-basedtheory and retrieval inhibition theory.ms research aimed at investigating the roles ofencoding elaboration and retrieval inhibition on intentional forgetting.In the experimentundergraduate students were given an item-by-item cued study task,either a direct(cued recall word-stem completion)or an indirect test (repetition priming word-stemcompletion),and a final recognition test. Two new methods were introduced into theresearch: one was carefully controlled word-stem completion with computer, and theother was so-called unrelated items. By comparing memory of unrelated items withremember-and forget-cued iterns,the result indicated that selective rehearsal and retrievalinhibition played roles on intentional forgetting.
