本研究以12名大学生为被试采用DRM范式,考察了视觉与听觉通道在编码阶段的错误记忆ERP效应,以从更深层面认识错误记忆的内在加工机制。研究结果表明,在编码阶段,在300-500ms及500-700ms的时间窗视觉通道均存在相继错误记忆效应(DIM),但DIM效应出现的时间及头皮分布不同,这不仅说明视觉通道与听觉通道在编码阶段具有不同的脑机制,而且表明DIM效应与学习项目的语义加工有着密切的关系。
In this study, 12 college students were used as subjects to investigate the erroneous memory ERP effect of the visual and auditory pathway in the encoding stage to understand the inherent processing mechanism of erroneous memory at a deeper level. The results show that in the coding stage, there are two successive DIMs in the time window of 300-500 ms and 500-700 ms, but the appearance of DIM effect and scalp distribution are different. This not only shows that the visual channel and auditory channel There are different brain mechanisms in the coding phase, and it shows that the DIM effect is closely related to the semantic processing of learning projects.
