Abstract :
Background: Aggression is one of the negative components of emotion and it is usually
considered to be the outcome of the activity of the Behavioral Inhibition and the Behavioral
Activation System (BIS/BAS): components which can be considered as predisposing factors for
personality differences. Therefore, the purpose of this study was to investigate the relationship between brain behavioral systems and the characteristics of the five factor model of
personality with aggression among students.
Methods: The present study has a correlation descriptive design. The research population included all of the Razi University students in the academic year of 2012-2013. The sampling was carried out with a random stratified method and 360 people (308 female and 52 male) were studied according to a table of Morgan. The study instruments were Buss and Perry Aggression
Questionnaire, NEO Personality Inventory (Short Form), and Carver and White scale for BAS/BIS. Finally, SPSS20 was utilized to analyze the data using Pearson correlation,
regression analysis, and canonical correlation.
Results: The data showed a significant positive relationship between the neurosis and
agreeableness personality factors with aggression; but there is a significant negative relationship between the extroversion, openness, and conscientiousness personality factors with aggression. Furthermore, there is a significant positive relationship between all the components of brain
behavioral systems (impulsivity, novelty seeking, sensitivity, tender) and aggression. The results of regression analysis indicated the personality characteristics and the brain behavioral systems which can predict 29 percent of the changes to aggression, simultaneously.
Conclusions: According to a predictable level of aggressiveness by the personality
characteristics and brain behavioral systems, it is possible to identify the personality
characteristics and template patterns of brain behavioral systems for the students which be
presented to them as a necessary training in order to control and manage of anger and aggression.
