The Influence Of Hostile Attribution Bias On Aggressive Behavior And Its Brain Basis

Aggression has been one of the most important subjects in psychological research for many years.Different scholars have difference opinion on the definition of aggressive behavior.At present,the relatively recognized definition in academic circles is deliberate intention to hurt others,and the injured individual has the motivation to avoid injury.There are many factors can affect aggressive behavior,according the general aggression model(General Aggression Model,GAM),it can be summed up as situational factors and individual factors in the situation.In personal factors,cognitive factors are one of the factors that can not go around.On the basis of the review,it is found that hostility attribution bias is an important factor affecting aggressive behavior.However,previous explorations on it are mostly based on questionnaires.Therefore,this study uses the advantages of previous research,will be in the economic field has been relatively mature paradigm(The Dictator Game,DG)were applied to the adaptation of the hostile attribution bias control variables,and the measurement of the distribution of money attack behavior in this situation of job seekers assessment tasks.In addition,there is little research on the cognitive mechanism of the biased attribution of hostility,especially the brain mechanism based on FMRI technology is more blank.Based on this,this article is divided into two studies one step to explore the relationship between the hostile attribution bias and the attack behavior and the brain mechanism.First,a review of previous studies on the bias of hostility attribution,and the compilation,collection and final determination of the cause of hostility in the experiment.In the end,12 reasons for the unfair distribution of the results were determined to be used for subsequent research.The pre-experiment based on the dictator paradigm was then carried out to find the most appropriate allocation scheme.A study on the comprehensive research results,the research group had done,found 7 yuan: 3 yuan allocation scheme for fuzzy ideal situation;6 yuan: 4 yuan of;8yuan: 2 yuan,9 yuan,1 yuan and 5 yuan,5 yuan is clearly the situation,in order to the efficiency of research,this study mainly concentrated in the first two times,after three rounds with a few in order to ensure the authenticity of the experiment.A formal experiment was conducted on the basis of the possible causes determined by the pre experiment and the allocation scheme.90 college students were recruited to participate in the study,and they were randomly divided into the hostile attribution group and the non-hostile attribution guide group.The results showed that the scores of M=4.95(SD=0.95)were significantly higher than those of the unanimity attribution bias group(M=4.40,SD=1.10),t=2.39,p<0.05.Study two adopted the experimental paradigm similar to that in research one.However,unlike the research one,it was implemented in the FMRI environment.In addition to the experimental results of one to one study,research two is also exploring the brain mechanism of the hostile attribution bias.The results showed as follows: 1)the behavioral experiment results were still attributable to hostile attribution.The score of aggressive behavior in the Guidance Group(M=4.80,SD=1.31)was significantly higher than that in the invincible attribution group(M=3.94,SD=1.40),t=2.10,p<0.05.2)The FMRI results showed that the brain base of the hostile attribution was the left Inferior Frontal Gyrus.The results of this study suggest that the hostile attribution bias can significantly predict the individual's attack behavior,with the brain based on the left Inferior Frontal Gyrus.These results provide a reference for the prediction and prevention of attack behavior.
