【 摘 要 】

Analyzing the influence of emotion on false memory through electroencephalogram is helpful to further explore the cognition function of brain. In this study, material emotion and participant emotion were introduced into Deese-Roediger-McDermott (DRM) paradigm experiment at the same time, which made the experiment process closer to real life. Different music was used to induce the emotion of 28 participants, and they were divided into positive group and negative group. Then, we analyzed the difference between the two groups from the behavior data, source location and cortex functional network of event related potential. The results of difference analysis show that the false memory rate of positive group (85 +/- 8.6%) is significantly higher than that of negative group (72 +/- 9.7%), and the activation degree and voxel number of the positive group are significantly higher than those of the negative group in the brain regions related to semantic coding (BA24 and BA45), and the compactness, the speed of information transmission and the small-world property of the brain network in positive group are significantly higher than those in negative group. The above results show that in the positive group, more brain resources are used for semantic association when they judge keywords, which confuse the keywords and learning words, and result in more false memories.
