重复学习对错误记忆通道效应的影响

The Influence of Repetition on the Modality Effect in False Recognition

本研究采用DRM范式以80名大学生为被试对错误记忆的通道效应进行了研究。实验采用三因素混合设计,运用信号检测论等方法探讨了重复学习对不同通道错误再认的影响。结果发现:1)汉语词表具有与英文词表不同的通道效应,表现为视觉学习的错误再认高于听觉学习;2)重复学习对视觉学习与听觉学习的错误再认产生分离性影响,即重复学习降低了视觉学习的错误再认,却提高了听觉学习的错误再认;3)信号检测论的分析表明:听觉学习在重复学习后对关键诱词的错误再认的增加是听觉学习对要义信息日益增加的敏感性连同较为宽松的提取标准协同起作用的结果。

The experiment examined the modality effect in false memory in the DRM paradigm. We utilized the 3-factor mixed design and explored the influence of repetition on the modality effect in false recognition with the method of SDT. We found in our experiment that 1 ）there were different modality effects in false memory between the Chinese lists and the English lists, namely, the false recognition following visual study was greater than following auditory study; 2） Repetition played a dissociated role in false recognition in visual study and auditory study, which showed that repetition reduced the false recognition in visual study, but enhanced it in auditory study; 3） the signal detection analysis suggested that the increased susceptibility to false recognition in auditory study after repetition stemmed from a combination of increased sensitivity to gist information and more lenient retrieval criteria; and the sharp reduction of false memory in visual study after repetition was attributed to more dependence on item-specific information than gist information.
