FOK产生机制的实验研究

通过以初中生和大学生为被试的两个实验探讨了FOK（Feeling-of-Knowing即“熟知感”）的产生机制，是线索熟悉性还是靶项目的可提取性（或记忆强度）决定FOK判断的等级。识记材料为90对中文词对.分前后两部分让被试识记，前后两部分词对之间安排三种关系：①完全相同;②仅线索词相同，③完全不同，这三种关系可选成不同的靶项目记忆强度和不同的线索熟悉性.两组实验结果一致表明，FOK的等级判断的高低取决于线索熟悉程度，而不随靶项目的记忆强度而变化.

AN EXPERIMENT STUDY OF THE MECHANISM OF FOK JUDGEMENT

Two experiments were designed to investigate the mechanism of FOK (Feeling-of-Knowing ). To explore whether FOK judgements was based on the target's memory trace target retrievability ) or on cue familiarity. We selected subjects from junior middle schools and universities.The memory materials were 90 Chinese word pairs. They were divided into two parts. Each part included 45 word pairs. There were three kinds of relation between these two parts of word pairs: 1.word pairs were completely the same; 2, only the cue words were the same; 3, word pairs were completely different. These three kinds of relation formed different memory strength and different cue familiarity. The results showed that FOK judgement was based on cue familiarity, but not on target's memory strength.
