ABSTRACT

The purpose of this study was to analyse differences in frontal lobe executive function of delinquency juveniles. In order to find out fundamental factors of the delinquency, this study divided the group into Adolescence- Limited and Life-Course-Persistent Delinquency juveniles with the use of delinquent classification scale. Then, this study was executed by three main neuro-psychological assessment scales(Wisconsin Card Sorting Test, Tower of Hanoi, go-no-go and the like) to compare the differences of the executive function between sub-domain groups. The participants are normal juvenile group(n=28), Adolescence-Limited Delinquency juveniles(n=23), and Life-Course-Persistent Delinquency juveniles(n=27). The Results indicate that first, in the course of using WCST(Wisconsin Card Sorting Test), there were significant differences in cognitive flexibility between normal juveniles and Adolescence-Limited and Life-Course-Persistent Delinquency juveniles. Second, there were differences between normal and delinquent juveniles on the Tower of Hanoi Test which is assessed the planning and organizing ability, but no outstanding differences between the sub-domain delinquent groups at the first operation except the concept of the planning time. Third, through the Stroop Task, the study was also able to focus on differences of self-control and inhibition between Adolescence-Limited and Life-Course-Persistent Delinquency juveniles. These result suggested that by indicating the hypothesis about the defect of the executive function of the delinquent juveniles and shedding light on the differences between sub-group of them, it is possible to hypothesize that there was defect or developmental immaturity on the frontal lobe of the delinquent juveniles. This study is important in that it is proved that there was neurological defect only in Life-Course-Persistent Delinquency juveniles with the neuro-psychological assessment scales. Moreover, the more effective measures for the proper guidance and education can be put into effect by reasoning the causes of juvenile delinquency.
