应用DRM范式,研究单个汉字语音关联对错误记忆的影响。实验一中,学习阶段呈现的各字表汉字与未呈现的诱饵字具有相同音节。再认测试发现,被试对诱饵字产生了明显的错误再认。实验二发现,当各学习字表内的汉字拥有相同声母或相同韵母时,被试对相应的两种诱饵字也能产生明显的错误再认,并且其效应与音节相同时基本一样。这些结果说明,汉字的语音关联可以诱发错误记忆现象,但其效应并不随语音相似度的增加而增加。研究提示,错误记忆可以来源于较低层次的基于知觉的加工;中文语音网络虽然易于激活,但激活程度有限。
False memory is a type of memory illusion where one claims to remember things that never happened.The Deese-Roediger-McDermott,or DRM,paradigm has been extensively adopted to investigate the factors influencing false memory.Using English words,previous studies have found phonological as well as semantic false memories.To investigate whether there is any effect of Chinese phonological association on false memory,two experiments were conducted in the present study.In experiment 1,subjects first studied several lists of Chinese characters with same syllables,and then took a recognition test.There were three types of characters in the test:studied items,lures (which had same syllables with studied items),and intruding items (which had no relationship with studied items).Subjects' task was to judge whether each testing item was "old" or not.Results showed that the proportion of lures labeled as "old" was significantly higher than that of intruding items.In experiment 2,lists of Chinese characters with only same onsets or same rhymes were presented in the study phase.Accordingly,the lures in the test phase shared same onsets or same rhymes with the studied items.Compared with intruding items,more proportion of lures labeled as "old" was found again.Moreover,the proportions of lures labeled as "old" did not have significant differences either between the same-onset and same-rhyme conditions,or between the two experiments.These results demonstrate that Chinese phonological association does have an effect on false memory,and this effect remains unchanged even when the phonological similarity increases.The present study suggests that false memory can result from low level perceptual-based processing,and that Chinese phonological network can be activated easily,but only to a limited extent.
