反馈方式和项目关联性对词语错误记忆的影响

错误记忆是指人们错误地将曾经发生过的事情判断为从未发生,或者将从未发生的事情判断为发生过.本研究运用DRM范式研究反馈方式和项目关联性对词语的错误记忆的影响.结果表明：1）反馈方式的主效应不显著,即在不同的反馈条件下,词语的错误再认率没有显著差异.2）项目关联性的主效应显著.再认词语与学习过词表的语义关联性越大,其错误再认率越高.3）反馈方式和项目关联性的交互作用显著.对于中等关联程度的词语来说,肯定反馈条件下的错误再认率要显著低于无反馈条件下的错误再认率,无反馈条件下的错误再认率要显著低于否定反馈条件下的错误再认率;而对于高等关联程度的词语和低等关联程度的词语来说,接受不同反馈方式被试的错误再认率没有显著差异.

THE INFLUENCE OF FEEDBACK AND ASSOCIATION ON FALSE MEMORY

Using DRM paradigm,the present study investigated the factors that influenced false memory.These factors were feedback and association.The results showed：1） The feedback factor was not a significant impact on false memory,which indicated that false memory did not change with feedback.2） False recognition under the condition of lowest association was significantly lower than those of high association （critical lure） and medium association.With the project association closer,the false recognition rate was increasingly high.The result implied that association was an important variable for false memory.3） There was an interaction between feedback and association on false memory.To the words of medium association,false recognition under the positive feedback was significantly lower that than under no feedback,and false recognition under no feedback was significantly lower than that under the negative feedback.To the words of high or low association,false recognition under different feedback condition has no difference.
