联系可觉察度对错误记忆的影响

本研究采用DRM词表学习法和图片刺激对学习法两种研究范式考察了关键诱饵与学习项目间联系可觉察度对错误记忆的影响。结果显示,学习项目与关键诱饵的联系可觉察度对错误记忆起重要作用:在词表学习范式中,随着联系可觉察度的提高,被试觉察到的词表的关联性更高,错误记忆就更容易发生;在刺激对学习范式中,随着联系可觉察度的提高,学习项目和关键诱饵间的差异区分性提高,导致二者间的关联性降低,从而减少错误记忆。本研究为进一步揭示错误记忆的机制、更好地理解记忆及其机制提供了新的证据,并对如何提高记忆效率具有一定的实际应用价值。

The Effects of Detected Relationship between List Items and Critical Lures on False Memories

Using a DRM paradigm and a paired picture-word stimuli method,the current research explored the effects of detected relationship between list items and critical lures on the occurrence of the false memory.The results showed that the detected relationship could influence the occurrence of the false memory.In the DRM paradigm,the more detectable the relationship was,the more rigid relationship between word-list and non-presented critical lures was established,and the more frequently the false memory occurred.In the paired-stimuli-learning paradigm,the more detectable the differences between list-item and lure were,the less confusion was made,and the less frequently the false memory occurred.The findings of the present study shed new light on the nature and mechanism of the false memory,which had important practical values in improving memory efficiency.
