摘　　要：采用ERP技术考察表象激活混淆与错误记忆的关系。发现:(1)在编码阶段,随后错误记忆的ERPs比随后正确记忆的ERPs在顶区、枕区和颞枕区有更大的晚正成分。(2)在提取阶段,错误记忆的ERPs比正确记忆的ERPs在顶区、枕区和颞枕区有更大的晚正成分。整个研究表明,表象激活混淆在错误记忆产生中具有重要作用。根据研究结果提出"表象激活混淆假设",认为人们虽然使用表象的信息表征方式,却无法获取与之联系的激活路径,容易混淆表象激活的来源。表象激活混淆是表象引发错误记忆的机制。In this study,the author investigated the brain mechanisms underlying the encoding phase and retrieval phase by means of ERP techniques to further tap into electrophysiological processes of mental imagery evoking false memory. The ERPs results showed that brain potentials in response to words at encoding were more positive if the corresponding object was later falsely remembered as a picture,and these ERP differences were largest at parietal,occipital and temporal- occipital scalp locations at 600- 900 ms and 900-1200 ms time intervals. Similar brain potentials during the memory test were more positive for false than for true memories. Repeated measures ANOVA yielded significant DIM effects of condition,indicating that false- memory ERPs were more positive than accurate-memory ERPs,and these ERP differences were largest at parietal,occipital and temporal- occipital scalp locations at 300- 900 ms and1200- 1500 ms time intervals. In coclusion,the present findings demonstrated that mental imagery had a important role in the creation of false memory. The author explained the findings of the inner mechanisms between mental imagery and false memory from the view of the Imagery of Activation Confusing Hypothesis,which provided specific view to understand the brain mechanism on how mental imagery evoked false memory.
