The Research On ERP Characteristics Of Different Cognitive Fatigue And Recognition Judgment About False Memory Tasks In Junior Middle School Students

On the basis of the previous studies, have two studies, use junior middle school students andE-Prime2.0programming, while recording behavioral data and EEG data. Study one is EEG characteristicsof different cognitive fatigue and recognition judgment in Junior Middle School Studentsˊword-basedfalse memory tasks, use classic "Learning-Recognition" research paradigm, present words successinduced late positive component (LPC), N100, P200, and the EEG characteristics of high cognitive andwithout cognitive; Study two is EEG characteristics of different cognitive fatigue and recognition judgmentin Junior Middle School Studentsˊenvent-based false memory tasks, present coherent videos, answer thequestions according to the videos content, look at the EEG characteristics of subjects, present videossuccess induced late positive component (LPC), N100, P200, and the EEG characteristics of high cognitiveand without cognitive. Because of different experimental material, there are still some difference betweenword-based false memory and envent-based false memory, it is worth studying also. Based on the analysisof the data and finally reached the following conclusions:First, word-based false memory tasks, the correct rate of correct recall (M=0.732) was significantlyhigher than that of the correct rate of correct negative (M=0.584);Second, envent-based false memory tasks, the correct rate of correct recall (M=0.693) wassignificantly lower than that of the correct rate of correct negative (M=0.753), the reaction time of correctrecall was significantly lower than the correct negative and false;Third, word-based and envent-based false memory tasks the amplitude of P200correct negative wassignificantly lower than missing;Forth, word-based false memory tasks the amplitude of LPC in fatigue induced high cognitivecorrections;Fifth, word-based and envent-based false memory tasks the incubation period of N100and P200highcognitive was significantly less than without cognitive;Sixth, word-based false memory tasks the amplitude of N100in the correct negative of central area,the Missing of the central area, the false of the central area, the false of the frontal area high cognitive bigger than the without cognitive;Seventh, envent-based false memory tasks the amplitude of N100in the correct of occipital area andthe false of the temporal area high cognitive smaller than the without cognitive.
