Abstract
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.

Abstract
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.

Abstract
The crucial difference between people with OCD and non-clinical individuals would be the presence of OCD-related dysfunctional beliefs. compulsions are aimed at undoing the intrusive thoughts. With respect of core symptoms of Obsessive Compulsive Disorder(OCD) deficit in cognitive inhibition is probable. But results are inconsistent in this field. Here researchers are aimed to study the probable IOR deficit in clinical sample of compulsive washing . this study is a causal- comparative research. Beck Depression Inventory - version II (BDI-II), Obsessional Beliefs Questionnaire- 44 (OBQ-44) and emotional Inhibition of Return test were administered of 47 clinical samples of compulsive washing. The results of MANOVA analysis showed that there is no differences between two groups in IOR (F(4,42)=-0.578, P=0.735; Wilk’s Lambda= 0.955; Partial η2= 0.045). Moreover there is a significant deference between reaction times in valid and invalid trails (t= 4.209; P≤0.01) that shows the general IOR phenomena in participants. This research failed to show cognitive inhibition deficit in clinical samples of compulsive washing according to their dysfunctional beliefs.IT seems that IOR deficient is not detectable in OCD patients according to exogenous attention. Other theoretical and experimental implications are discussed.

Abstract
The aim of the present study was to investigate prospective and retrospective memory and cognitive ability in three groups of personality based on reinforcement sensitivity theory. For this purpose, first, 358 students Bu Ali Sina university were selected through a multistage cluster sampling. Then Brain / behavioral Systems questionnaire were distributed among them to be answered. After initial data analysis, 51 of them, based on cluster analysis in Brain / behavioral Systems questionnaire were selected, in order to test the hypothesis of this study, participants were studied in dimensions of prospective and retrospective memory and cognitive ability. The collected data were analyzed using descriptive indicators, multivariate analysis of variance and post hoc tests. Results showed significant difference between three personality groups in memory and cognitive ability. So that, group with high behavioral inhibition system sensitivity have better performance in components of retrospective memory, prospective memory, general memory and ability of naming; group with high sensitivity of fight-flight-freeze system have higher scores in prospective memory and general memory. The results showed that more active and less active of brain/ behavioral systems may be in close relation with memory and other cognitive abilities. It seems that cognitive abilities can to be influenced by the brain systems associated with reinforcement sensitivity and thereby cognitive functions changed.

Abstract
| Combining psychoanalysis and neurology feels peculiar at first. The combination that tries to bind concepts of psychoanalysis with neuroscience in order to provide an integrates knowledge for better understanding of human mind. However, interaction between psychoanalysis and neuroscience has come to attention during past three decades. Purpose of this study is to investigate and find correlation between three styles of defense mechanism, Mature, immature and neurotic defense mechanism with executive functions within universities students of Tehran. For this matter a study performs on a sample of 140 students (including 76 women and 64 men) by available sampling. The instruments of this research were The Defense Styles Questionnaire (DSQ40) and four computer base test for executive functions including Continues Performance Test (CPT), Strops, 1-back, Go-No Go. The data was analyzed by Pearson correlation and multiple regression method. This study demonstrated significant relation between styles of defense mechanism and executive functions and also forms a model to estimate executive function shares in neurotic and growth defense mechanisms. As a result, the findings suggest that one’s performance on executive functions can affect their style of defense mechanism. |

Abstract
| Making risky decisions in adolescents has become a major public health concern and understanding the correlations affecting this process makes it possible to implement prevention plans. Therefore, the present study was conducted to investigate the effect of positive and negative mood induction on risky decision-making by moderating high behavioral brain systems. In order to meet this aim, 327 adolescents aged 18-13 years in Isfahan were randomly selected and screened through the Behavioral Brain Systems Questionnaire (BAS / BIS). Based on the standard score, two groups of 24 participants including high BAS and BIS were selected. The members of each group were randomly divided into two equal subgroups, we induced positive mood in the first subgroup and negative mood in the second subgroup using Pieces of emotional movies. Participants completed the Balloon Risk Test (BART) and the Positive and Negative Emotion Scale (PANAS) before and after mood induction. Results of data analysis by univariate factor covariance analysis showed that there is a significant difference between inducing positive and negative mood on risky decision making (p≤ 0/05) and positive mood leads to increased risky decisions, The findings also showed that behavioral brain systems as biological personality traits significantly moderate the effect of mood induction on risky decision making (p≤ 0/05). This means that adolescents with a high behavioral activation system have more hyperactivity when faced with positive moods and they are more at risk than people with behavioral inhibition systems while adolescents with behavioral inhibition systems, on the other hand, are more sensitive to negative moods and signs of punishment and they are more cautious. |

Abstract
This research aimed to compare the effectiveness of mindfulness-based socio-emotional learning program with/and without Transcranial Direct Current Stimulation on sustained attention and response inhibition in children with attention deficit/hyperactivity disorder. This research was a semi-experimental study with a pre-test and post-test design with a control group. The statistical population included all students aged 11 to 14 who referred to child and adolescent counseling centers in Khoy city in 2021-2022 year. 45 people with attention-deficit/hyperactivity disorder of the mixed type were selected from among those who refer to the treatment centers by the purposeful sampling method and randomly replaced in two experimental groups and one control group. The first experimental group received the mindfulness-based socio-emotional learning program combined with Transcranial Direct Current Stimulation and the second experimental group received the mindfulness-based socio-emotional learning program for 8 weeks, but the control group did not receive any intervention. All participants were measured before and after the training using continuous performance test and GO/NO-GO test. For data analysis, multivariate covariance analysis was used in SPSS program. Data analysis showed that mindfulness-based socio-emotional learning combined with Transcranial Direct Current Stimulation compared to the other two groups and mindfulness-based socio-emotional learning compared to the control group were more effective on sustained attention and response inhibition. According to the findings, it can be suggested that the mindfulness-based socio-emotional learning program combined with Transcranial Direct Current Stimulation is an effective intervention to improve the cognitive functions of children with attention deficit/hyperactivity disorder.

Abstract
Purpose: The purpose of this study was to compare the cognitive functions of people with passionate love and normal people. Method: In this research, 500 students from persian golf University Bushehr , who studied in 2017-2018, were selected through purposeful sampling with a mean age of 21 years and filled the passionate love scale (PLS). Individuals who scored between 135 and 106 in the passionate love group and Those who scored 105-15 were in the normal group. Of these people, 204 were selected for Stroop, Wisconsin and Continuous Performance tests and analyzed by multivariate analysis of variance. Results: the study showed that there is a significant difference between respondents with passionate love and normal people in terms of inhibition. No significant difference was observed between the two groups in the cognitive flexibility and attention (P> 0.05). Discussion: According to the findings, people with passionate love of inhibition have a weaker response than normal people, and the lack of difference between the two groups in the component of cognitive flexibility and attention point to the similar performance of these two groups in cognitive functions. Findings show the attention component in the two groups is different based on gender.

Abstract
In different parts of the world, people speak different languages to each other. Some parts of the world are more linguistically rich and more than one language is spoken in those regions. The aim of this study was to evaluate and evaluate the executive functions of the brain including cognitive flexibility, selective attention and response inhibition in monolingual and bilingual male and female students of Bu Ali Sina University of Hamadan. This research has been done by descriptive and causal-comparative method using complex Stroop computer test. The statistical population selected for this study were bilingual and monolingual students of Bu Ali Sina University. The test was performed on 214 male and female students. Data obtained from 165 students were analyzed by independent t-test and one-way analysis of variance. The obtained results showed that there is a significant difference between gender and executive functions studied in this study. But there was no significant difference between bilingual and monolingual individuals with these functions. In this study, we concluded that gender affects the executive functions of the brain, but bilingualism and monolingualism do not affect the executive functions of the brain.

Abstract
Executive functions are important structures that play an important role in controlling and directing behavior. This research was conducted with the aim of investigating the mediating role of emotional intelligence in the relationship between theory of mind and executive functions (cognitive flexibility and response inhibition). The current research method was correlation and structural equation modeling. The statistical population of the research included all female students aged 13 to 18 in Khomeini Shahr city in 2021, of which 300 were selected for the research sample using the available method. To collect data from the emotional intelligence questionnaire (Schutte et al., 1998), software tests of Wisconsian card sorting (Grant and Berg, 1984), go /no go (Hoffman, 1984) and mind reading through eye images (Baron-Cohen et al., 2001) were used. For data analysis, Pearson's correlation coefficient and structural equation model were used in AMOS-24 software. The findings showed that theory of mind had a positive and significant direct effect on emotional intelligence with a coefficient of 0.233 and on cognitive flexibility and response inhibition with a coefficient of 0.133 and 0.218 respectively (P<0.01), intelligence Emotion with cognitive flexibility and response inhibition had a positive and significant direct effect with coefficients of 0.144 and 0.337 respectively (P<0.01). The indirect effect of theory of mind on flexibility and response inhibition with the mediating role of emotional intelligence was 0.033 and 0.078, respectively. Therefore, the results indicated the decisive role of theory of mind and emotional intelligence in predicting cold executive functions (cognitive flexibility and response inhibition). Finally, considering the relationship between theory of mind, emotional intelligence, cognitive flexibility and response inhibition, by increasing theory of mind and emotional intelligence, it is possible to help improve the components of executive functions.

Abstract
Risky behaviors are common in adolescent populations worldwide. It is believed that the disturbance in emotion regulation and emotional inhibition leads to an increase in risky behaviors in teenagers. The aim of this study was to evaluate the effectiveness of metacognitive interpersonal therapy on the cognitive regulation of emotion and emotional inhibition in adolescents with high-risk behaviors. The method of semi-experimental study with pre-test and post-test with a control group was conducted on all girls with high-risk behaviors who referred to Tehran counseling center in 2022. 30 teenage girls with risky behaviors were included in the study. Controlled study. Participants were selected by purposive sampling method and randomly divided into two experimental and control groups (15 people in each group). After conducting the pre-test using Carver and White Behavioral Inhibition/Behavioral Activation Scale and Gross and John Emotion Regulation Questionnaire, the experimental group received metacognitive interpersonal training for 8 sessions of 90 minutes each week, while the control group received no training. did not. To evaluate the effect of training, a post-test was taken from both experimental and control groups. The obtained data were analyzed using SPSS.23 software and multivariate covariance analysis method. The results showed that metacognitive interpersonal therapy caused a significant difference between the cognitive regulation of emotion and emotional inhibition in adolescents with high-risk behaviors. (P≥0.001). Based on these findings, it can be concluded that metacognitive interpersonal therapy has a positive effect on the cognitive regulation of emotion and emotional inhibition in adolescents with high-risk behaviors. Therefore, it can be said that this program can be used to help teenagers with risky behaviors.
