Abstract
Inhibition as an important component of executive functionsplays an important role in the incidence of juvenile delinquency.The aim of thisresearch is to investigate the role ofbehavioral inhibition in the Juvenile delinquents with or without history of substance abuse.42 juvenile delinquents and 20 normal adolescents, as the control group, were selected through cluster random sampling method. Juvenile delinquents were divided into two groups: with or without history of substance abuse and these two groups were matched for age and sex andThen the two groups were assessed through tests including go no go and stop signs.Data were analyzed using multivariate analysis of variance test, univariate analysis of variance test and Tukey test. Analysis of data showedthat the juvenile delinquents, in comparison with the normal adolescents,performed poorly on behavioral inhibition,but there was no significant difference between groups with or without history of substance abuse (p>0.05).Therefore, Insufficiency of behavioral inhibition can be one of the underlying causes of tendencies to delinquency. The findings of thepresent studyemphasize the necessity ofthe focused interventions to improve the executive function in juvenile offenders

Abstract
The aim of the current study was to examine the effectiveness of cognitive behavioral group therapy based on executive functions in improving the executive functions in students with Attention Deficit / Hyperactivity Disorder (ADHD). This study was carried out in 2011-2012 academic year using pre-post- test design with a control group. Students of Mashhad’s Ferdowsi University who were previously diagnosed with ADHD or who were showing the symptoms of ADHD at the time of the study were invited to participate in this study. Primary diagnosis was based on the Barkley Adult ADHD Rating Scale—IV (BAARS-IV) and final diagnosis of the disorder was done through psychiatric interview. Finally, 32 students were selected as the subjects of the study and were randomly divided into a control and an experimental group. The experimental group received EF based cognitive-behavioral group therapy. In addition to BAARS-IV all participants completed Barkley Deficits in Executive Functioning Scale (BDEFS) at pre-post-test assessments. Results of MANCOVA & ANCOVA tests showed that participants in the experimental group improved their executive functions including time management, planning, organization, self-motivation, and emotional self-regulation. Results of the study demonstrated that EF based cognitive-behavioral group therapy was effective in improving the executive functions in student with ADHD. Therefore, along with other treatments this treatment can be used as a modern approach for improving the executive functions of students with ADHD.
