研究以故事情境短文为实验材料，探讨了即时再认与延时48小时后再认条件下虚假记忆变化表现及其与真实记忆电生理活动的差异。结果发现，延迟48小时后虚假记忆诱发的LPC成分比即时再认更正性；即时再认条件下虚假记忆与真实记忆认知加工差异表现在有意回想加工及额叶后提取加工阶段，而延迟48小时后这种差别仅表现在额叶后提取加工阶段。上述结果为虚假记忆存在随时间变化及其与真实记忆相分离提供了电生理证据。

Bartlett （1932） demonstrated that memory is a process of construction, and the content of the memory becomes more reasonable with time by using qualitative analysis. His research marked the beginning of the false memory .McDermott （1996） reported 48h interval between study and test produced probabilities of false memory that exceeded those of true memory. The current study investigated the cognitive and neural electrophysiological processes of the retention interval effect on false memory. The experiment was conducted on 22 healthy right-handed undergraduates with five story contexts as the material during study phase. The participants studied 5 blocks （one story context in each block and 60 associated target words in each list） and did an old/new recognition test both after short and long delay. Before long delay test, participants must recall the story context as much as possible for 120s according to the story cue. Results showed that （1） False recognition demanded more RT than true recognition. （2）The spatial and temporal distributions of LPC associated with false memory were more positive after long delay relative to short delay. （3）Attenuation of the LPC elicited by false memory relative to true memory after short delay, but there were not different after long delay. （4）The amplitude of LSW elicited by false recognition was greater than true recognition and Correct-Rejection recognition after both delays. In conclusion, the results demonstrated that false memory had showed the different information processing models between short and long delay. The diversities were recollection-based process and post-retrieval process after short delay, but the diversity only focused on the post-retrieval process after long delay.
