Executive function is a set of processes which is responsible for the cognitive, emotional, and behavioral and performance conduct of human being at the time of activities and problem solving. The aim of this study was the comparison of the executive function of the reorganization of thought in adolescents with cannabis abuse. This study is a casual comparison, so 50 adolescents with cannabis abuse who lived in Ahwaz’ juvenile institution and were between the age of 15 and 18 were selected and were compared with 50 normal adolescents of a high school in Ahwaz city, as the control group, who were similar to each other in terms of some demographical variables and who were selected through availability sampling. To collect the data, Gestalt test, TOVA test (as a continual performance test) and Vygotsky’s concept formation test were used. The data was analyzed through multivariate analysis of variance (MANOVA). The results showed that the adolescents with a cannabis abuse disorder had weaker performance in the behavior inhibition and reconstruction of thought than the normal adolescents and there was significant difference between these two groups. Generally speaking, considering the results of the study, i.e. the weaker performance of the adolescents with cannabis abuse disorder in executive functions (behavior inhibition and reorganization of thought) than the normal students, it seems that this weakness would lead to the inappropriate social behaviors, problems in decision making, inappropriate judgment, problems with innovation and change, distractibility and problems in various aspects of memory.

This study to do identifying processes and strategies of emotion regulation and designing developmental model based on self-regulation patterns. Thus, this study examined emotion regulation with a developmental perspective in children age 4 - 12 years In Tehran. To 108 children, scenarios including four emotions namely sadness, madness, worry and pain were read. After the stories were read to the subjects and duly understood by them, and once an emotional atmosphere was created, subjects had an emotion regulation interview (ERI) and observation. Findings show that emotion regulation developed from extra-organismic self-regulation (input and output) toward intra-organismic (central processing). This trajectory is situation, attention and perception change, responding and expression modulating and internal-cognitive regulation.
