The Influence Of Different Emotional States On False Memory Under The DRM Paradigm

False Memory is the result of "processing" or "tampering" of memory.Relative to the real memory(True memory),it is a kind of memory distortion.That is to say,if people deviate from the facts when recalling their past events,false memories come into being.False memory has attracted the attention of scholars in the academic field.In recent years,erroneous memory as a special field has attracted wide attention from psychology,sociology,cognitive neuroscience and other disciplines.At present,most of the researches on false memory are focused on Influencing Factors of false memory.On the basis of the existing research,this paper uses the DRM paradigm(Deese-Roediger-Me Demrott Paradigm)to explore the effects of different emotional states,presentation time and early warning on false memory.This study includes three experiments: the experiment one is 3 x 3 mixed experiment design,the independent variable A is different emotional state(positive emotion,neutral mood,negative emotion),independent variable B is the vocabulary type(key words,learning words,unrelated words),and the dependent variable is the error rate in the memory test(the sum of the leakage rate and false rate).The second experiment is 2 x 3 x 3 mixed experiment design,the independent variable A is the different emotional state(positive emotion,negative emotion),the independent variable B is presented time(250ms,1000 ms,2000ms),the independent variable C is the word type(key words,learning words,unrelated words),the dependent variable is the error rate(false rate and false report)in the memory test.The sum of the rate.The experiment three is a mixed experiment of 2 x 2 x 3.The independent variable A is a different emotional state(positive emotion and negative emotion).The independent variable B is an early warning state(with early warning,no warning),and the independent variable C is a lexical type(key words,learning words,unrelated words),and the error rate(false rate and false rate)in the memory test.The sum of them.The results of the study show that:(1)the false report rate of the key words in the positive emotion group is significantly higher than that in the neutral mood group and the negative emotion group.That is to say,under positive emotions,there will be more false memories.(2)no matter in positive,neutral or negative emotions,information that is not related to the current memory is not easy to cause false reporting rate,and false memory often occurs in information extraction that is associated with memory events.(3)the presentation time has a significant impact on the false report rate of the key words.It can be generally expressed that the false report rate of the key words decreases with the extension of the presentation time.(4)no matter the key word rate or the missing report rate of learning words,the interaction between different emotions and presentation time is not significant,but the main effect is significant.No matter how long the word is presented,the error rate of negative emotion and key words is always less than that of the key words in the same time.(5)the warning words before the learning stage effectively reduce the false positive rate of the key words.(6)no matter in positive or negative mood,the monitoring process of false memory exists.
