现实性监控研究述评

现实性监控是来源记忆的重要组成部分.总结分析表明,现实性监控的研究成果主要体现在如下方面：①学习项目的比例、学习和测验阶段之间的干扰任务、被试的想象能力等均对现实性监控存在一定的影响;②儿童的现实性监控能力随年龄增长而提高,老人的现实性监控能力相对较低;③不同病人在现实性监控中有不同的困难;④内部来源与外部来源提取激活的大脑区域不同,前额区在区分两类项目时的作用明显.今后应在整合研究结论、建立相应认知模型、构建前额区和顶区联合作用的神经网络和应用推广等方面加强研究.

Reviews on the Studies of Reality Monitoring

Reality monitoring is an important aspect of source memory. Reviews demonstrate that （ 1 ） the item ratio during study stage, the disturbing tasks between study and test phases, the imaging ability of subjects are the important factors that can influence reality monitoring; （2） the performance for reality monito- ring in children and old adults is relatively lower than that of the young adults ; （3） some types of pa- tients show significant deficit in reality monitoring; （4） the neural mechanisms engaged in internal and external source retrieval are different, the prefrontal cortex is an important area in differentiating these two types of sources. In future, the research of reality monitoring should focus more on the integration of different results, the establishment of the cognitive model ,the neural integration between prefrontal cor- tex and temporal area and its application.
