The aim of this study was to investigate the effect of emotional experience induction on working memory performance with regard to students' positive and negative metacognitive beliefs. The present study is an semiexperimental study of pretest-posttest type with a control group. The statistical population of the study was students of Kharazmi University. 80 subjects were screened using the Wells (1997) standard metacognitive questionnaire into 4 groups of positive high, positive low, negative high, and negative low metacognitive beliefs. ANOVA with repeated measures was used to analyze the data. According to the research findings, in the group with high characteristics of positive metacognitive beliefs, working memory performance increased significantly after positive emotional induction, but no change in memory performance was observed after negative emotional induction. In the group with low characteristics of positive metacognitive beliefs, working memory performance increased significantly after positive emotional induction and decreased significantly after negative emotional induction. In the group with high characteristics of negative metacognitive beliefs, working memory performance did not change after positive emotional induction but decreased significantly after negative emotional induction. In the group with low characteristics of negative metacognitive beliefs, working memory performance increased significantly after positive emotional induction and decreased significantly after negative emotional induction. According to the results of the study, memory performance in students with positive metacognitive beliefs is more influenced by positive emotional experiences, and in students with negative metacognitive beliefs, it is dependent on the induction of negative emotions.

Aim: This study aimed to compare the executive functions of patients with hoarding disorder and normal people in the city of Mashhad. Method: The design of the present study was causal-comparative and its statistical population consisted of people referring to Health Center No. 3 in Mashhad in 2017. The statistical sample included 30 individuals with hoarding disorder and 30 non-clinical participants. Data was collected using a structured interview, the revised version of Frost and Stecti storage behavior (SAL), and Back and visual-auditory computer tests. Multivariate analysis of variance was used to analyze the data. Results: The research findings showed a significant difference between people with hoarding disorder and people without clinical symptoms in answers (P = 0.001, F = 55.38), sustained auditory attention (P = 0.001, 48.61), and sustained visual attention (P=0.001, F=49.12) and people with hoarding disorder have a lower mean. In the mean reaction time, the differences were significant (P=0.001, F=36.684) and people without clinical symptoms had a higher mean. There was no significant difference in visual and auditory response inhibition (P<0.05). Conclusion: The research results showed that the performance of people with hoarding disorder in executive actions (working memory and sustained attention) is weaker than those without clinical symptoms..

Aim: The treatment model focused on Yang's schema is an innovative combination of cognitive behavior therapy with Gestalt and thematic relations of psychoanalytical approaches. The present study was conducted to identify the effect of schema-focused cognition group therapy training on the adjustment of primary maladaptive schemas in adolescent girls in divorced families. Method: The research was carried out in the framework of a semi-experimental pre-test and post-test design with a control group. The statistical population included all adolescent girls from the divorce family in Ghaemshahr welfare in 2018, from whom 40 people were selected through convenience sampling and were randomly assigned to the experimental and control groups. Yang's (1988) early maladaptive schemas questionnaire was used to collect data. the subjects were measured according to the research designs in two stages before and after the group training. The program was performed for eight sessions of 90-minute group training for the experimental group, but the control group did not receive any training. Univariate analysis of variance was used to analyze the data. Results: The findings indicated that the cognitive therapy group focused on the schema that affects rejection/rejection, impaired self-management and performance, impaired limitations, and other orientations in adolescent girls in divorced families in Ghaem city. Conclusion: The result of the study confirms the effectiveness of schema therapy in correcting maladaptive schemas and can help adolescent girls in the divorce family to adjust the schemas and can be used as a helpful model in psychological counseling for girls living on welfare.

Introduction:The purpose of present research was the investigation of the effectiveness of computer-based cognitive training on working memory on attention, response control, and central executive working memory of children with specific learning disabilities. Method: The research method was semi- experimental with pre-test post-test fallow-up. A total of 27 students aged 8 to 12 years with a specific learning disorder diagnosis were randomly selected from the centers of special learning disorders in Tehran (Robatkarim).The 27 subjects were peer and clustered into 3 groups based on component, phonological loop and visuospatial sketchpad of the HAFBAK test and the assessment of specific learning disorder (LDES).Then, using the IVA test and the central executive component of the HAFBAK test, a pretest was performed. After 18 session of 50 minute computer- based cognitive intervention, on 27 subjects post-test was performed. After 3 months, the fallow-up test was performed. For analyzing the data descriptive statistics and repeated measure variance analysis method were used. Results: The finding of this research showed that there was a significant difference between the 3 groups in per-test post-test and fallow-up test in the areas of attention, response control and central executive component. Conclusion:Therefore, computer-based cognitive training intervention increased the attention, response control and the central executive component of working memory in children with specific learning disabilities.

Introduction: The purpose of the present study was to study the association between the response inhibition executive functions of response inhibition and working memory and the development of the mind theory in primary school children. Methods: This research method was correlational. The population in this study consisted of all elementary school students in Mashhad in the academic year 1396-95. The sample consisted of 180 students randomly selected and matched by age, gender, and grade. Data collection tools in this study consisted of 38 questions form the Theory of Mind, Morris et al. ( ), Stroop Test and the Wechsler Memory Scale Active. The data collected were analyzed using correlation and linear regression analysis to test the research questions. Results: The results showed a positive and significant relationship between the executive functions of response inhibition, working memory and the development of theory of mind. Also a correlation was found between response inhibition and working memory's ability to predict the level of theory of mind. Furthermore, the results showed a positive relationship between theory of mind and response inhibition and working memory span. Conclusion: In general, executive functions, particularly working memory and response inhibition play decisive roles in anticipating and development of human mental abilities, including the ability of the conceptual mind. In addition, improving these actions led to greater recognition of social human understanding. Therefore, paying attention to learners’ working memory capacity and the effectiveness of learning and teaching materials designed to create the ultimate objective of all of them, or facilitate the development of cognitive functions, display significant effects.

Introduction: The aim of this study was to compare the executive functions (flexibility, planning, and organizing) and memory (active and passive) of monolingual and bilingual students. Method: For this purpose,120 students, including 60 male and female students who were Persian-speaking monolinguals and aged between 7 to 12 years (30 girls, 30 boys) and 60 Armenian-Persian bilingual students (30 girls, 30 boys) from the second to the sixth grade in district 8 of Tehran were selected by convenience sampling. Andre-ray test was used to measure executive function (planning and organization), and Wisconsin test was used to measure executive function tests (flexibility). Furthermore, 3 × 3 Matrix of Cornoldy was used to measure working memory and Matrix 5 × 5 Cornoldy was used to assess passive memory. Data were analyzed by two-way ANOVA using SPSS software. Results: The results showed that the executive functions of organizing and planning of monolingual students are different from bilingual students. However, there was not a significant difference between the two groups in the passive and working memory. In addition, significant differences were not observed between the genders, except that in monolingual students the executive function of flexibility of girls was better than boys. Conclusion: Based on the results and the advantages of bilingual students in executive functions over monolingual students, early second language education in preschools could be recommended.

The purpose of the present study was to examine the effective of emotion regulation strategies training on moral judgments with regard to the capacity of working memory. Thus, hundred and fifty eight university students (45 males and 113 female) from Kharazmi University were participated in this study. All participants were tested using working memory index and based on their scores distributions, two groups with high and low working memory abilities were selected for the training sessions. Each group, 14 participants (9 females and 5 males), have been trained through the emotion regulation strategies for ten sessions. Moral judgments in five different categories (personal, easy personal, difficult personal, impersonal and control dilemmas) have been examined in three different stages Data were subjected mixed analysis of variance. The results showed that there were no significant differences in utilitarian responses and reaction times to moral judgment dilemmas between two groups with low and high working memory scores. Also, the findings indicated that emotion regulation strategy training resulted in an increase of utilitarian moral choices for all of the moral dilemmas relative to control dilemmas. However, emotion regulation strategy training had an effect on the reaction time in response to the as well as difficult personal moral dilemmas. According to these findings, it seems emotion regulation strategy training had an effect in utilitarian responses and the reaction time, especially for personal moral dilemmas. This could be considered as an indicator of how emotion regulatory strategy training can influence the emotional response during moral judgments.
