A Comparative Study about Function Planning Frontal Lobe Delinquent Aggressive Adolescents, Aggressive Non-delinquent Adolescents and Normal Adolescents

The present study aimed to compare the planning function of frontal lobe in delinquent aggressive adolescents, aggressive non-delinquent adolescents and normal adolescents. This is a causal-comparative research. The sample consisted of 3 groups of 35, chosen from delinquent aggressive, aggressive non-delinquent and normal adolescents, who were matched according to these variables: age, sex, education and social and economic status. Research data, collected according to Eysenck Aggression Inventory and planning test (CAS), were interpreted by these statistical One-way ANOVA, and Tokey method. Data analysis indicated that there is a meaningful difference between operation of aggressive delinquent adolescents, aggressive non-delinquent adolescents and normal adolescents in the process of frontal lobe of planning (P<0.01). The results showed that delinquent aggressive and aggressive non-delinquent adolescents had poorer function of planning as compared with normal adolescents. Normal adolescents had better function of planning in relation to delinquent aggressive and aggressive non-delinquent adolescents. Aggressive non-delinquent adolescents had poorer function of planning than the normal group, and delinquent aggressive adolescents had poorer function of planning than the two other groups. It’s likely that the existence of neuropsychology deficits such as weakness in function of planning in aggressive people led to their poorer performance in comparison to normal people.
