The Influence Of Self And Others' Name Priming On Emotional Information Processing Of Different Valence Intensities

Different valence of emotional information produces different emotional experience for people.In fact,even the same valence of different intensity of emotional information can cause great differences to people's cognition and behavior.For example,We can get rid of low negative emotions through appropriate adjustment and won't cause too much hurt,but our body and mind will be damaged with strong negative events.People will be happy and work efficiency with low positive emotions,while strong positive can drive man mad or even make unwise decisions.We also have experience the different psychological feeling in daily life.Besides,it is very important significance for the individual about Self relevant information.Present study research different emotion valence intensity about processing features and neural mechanisms after the establishment of self related or others by the ERP technique.Experiment one use 2(priming type: self name,other name)x3(emotion valence intensity:strong negative,low negative,neutral)two factors experiment design.The results showed as follows:the amplitude of P1 and P2 appeared interaction of the two factors in the occipital area.There is larger amplitude trend for P1 in self name priming under strong negative conditions;While larger P2 amplitude is caused by other name under low negative conditions.Experiment two appears 2(priming type: self name,other name)x3(emotion valence intensity: strong positive,low positive,neutral)x3(brain region :left,middle,right)triple interaction effect.LPC amplitude appears the triple interaction effect and its latency appears the interaction of priming type and emotion valence intensity in the parietal-occipital regions.Further analysis found that LPC amplitude was larger with self related rather than other related priming in the central brain regions under the neutral condition;The latency of self name priming is longer than the others under neutral condition;The latency of self name priming is short than the others under strong positivel condition.Comprehensive these two experiments,these study get the following conclusions:1.Whole experiment results accord with self positive bias effect,the advantage of self associated with positive emotion is just under strong positive emotions,while others related to negative emotions occurs only on the condition of low negative.2.Other threat detection is affected by emotion potency intensity,producing other threat only under the condition of low negative condition.3.In particular,individual is sensitive to valence intensity changes in negative emotion stimuli even after the establishment of self related or other related.4.In positive emotion experiments,it is difficult to analysis and evaluate neutral information when it is related to self name,because the valence of neutral information is ambiguous.
