不同实验材料下有意遗忘过程的实验研究

有意遗忘是一种新的记忆研究的实验范式，实验中要求记忆的项目的回忆分数大于要求忘记的项目的回忆分数，对此现象的解释有两种理论，一是编码理论；二是提取抑制理论。研究采用无关、形似、同音和同义四种实验材料，利用字表方式呈现，被试为大学生。实验结果表明；1、被试既有对遗忘项的编码抑制，又有提取抑制。2、有意遗忘过程中的抑制能力与材料性质(上下文关系)有关。

Studies on Intentional Forgetting to Different Experimental Materials

Intentional forgetting is a new experimental paradigm on memory. The recall score of memorizing items is always higher than the ones of forgetting items are in the experiment. Two theories explain the paradigm at present. One is coding theory, the other is retrieval inhibition theory. The study adopts irrelevant material, resemble material, homophonic material and synonym material. The experiment makes the list method. The participated is uudergraduates. The results are as follows: (1) the subjects not only rehearsed the intentionally items but also were observed the retrieval inhibition to the items that asked to forget. (2) The inhibition on the intentional forgetting concerns with material character.
