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.

The aim of the present study is the predict of worry based on behavioral activation and inhibition systems, cognitive emotion regulation strategies and intolerance of uncertainty in students. In terms of objective, this study is off is study is the fundamental type, and in terms of data collection, it is of the correlation type. For this purpose, 200 students were selected using convenience sampling (available sampling) from Masters students at the Islamic Azad University of Tabriz in 2014-2015 school year. The participants were asked to answer the measures of behavioral activation and inhibition systems (BAS/BIS), Cognitive Emotion Regulation Questionnaire (SERQ), intolerance of uncertainty Scale (IUS) and the Penn state worry Questionnaire (PSWQ). Data were analyzed by the analysis of variance and stepwise regression. Results showed that there was a significant positive correlation between the variables of behavioral inhibition system, negative cognitive emotion regulation strategies, and intolerance of uncertainty in one hand, and worry in another hand (p<0.01), and there was a negative significant relationship between the positive strategies of cognitive emotion regulation and worry (p<0.01). These variables were able to predict 1/54 of the total variance of concern (p<0.001). In addition, the relationship between the behavioral activator system variable and worry was not significant. Worry is related to a variety of negative consequences, including a high degree of emotional reactivity and inefficient regulation styles. Thus, the findings of this study have practical implications in the clinical arena.
