A Study On The Cognitive Neurological Mechanism Of Early Warning On The Effects Of Source Memory Processing

Source memory is a source of information to make judgments of memory, into the coding phase and extraction phase, in this study, in the form of warning, indirectly strengthened the source memory of the process, subjects were asked to focus more on the degree of processing source This study used ERPs technology, namely to explore the emotional importance of early warning and early warning two angles of the encoding process of neural processing mechanisms for processing of the source, in the learning stage, experimental or not an important source stressed, emphasizing the second experiment Sources have negative emotional disturbance; in the test phase,subjects were asked to carry out the source of the old and the new decision task.Experiment 1 found that the behavior of the correct rate, warning prompt the correct rate of the old sources of important projects to be significantly higher than the rate of the source is not important right, and the correct rate of new projects is nothing to do with the importance of the source in the reaction, warning prompts an important source of old items to be lower than the warning prompt unimportant source of old items; ERP results showed that appear DM effect on 135-280 ms, concentrated in the prefrontal cortex and frontal areas, error code can induce more negative than the correct coding volatility in the old and new effects, sources in the warning prompt important case, there is an incubation period on 200-450 ms significant effect of old and new, the incubation period incubation period than the old items for new projects coming in advance.Experiment 2 found that the behavioral of a significant main effect of mood on the correct rate, warning prompt negative source, whether new or old project project project results in a neutral source is higher than in the reaction, the mood of the performance no significant effect; ERP and 800-1200 ms found that in the presence of the amplitude of the 350-550 ms emotional valence significant main effect, subjects processed negative than neutral source of origin evoked more negative amplitude.Main effects do not exist in the old effects and DM effect.The results showed that the source of the memory process, the importance of early warning and emotional subjects were led to adopt a more cautious approach, making subjects better distinguish memory source, thereby strengthening the source memory processes.
