The purpose of the present study was to investigate the relationship between traumatic childhood experiences and executive functions with the mediating role of emotional processing. This research was a type of correlation study and structural equation model. The statistical population of the study consisted of all the students of Tehran city, from which 270 people from Al-Zahra University (S) were selected using available sampling. To collect data, the childhood trauma questionnaire (Bernstein et al., 2003), the executive skills questionnaire (Street et al., 2019), and the emotional processing scale (Baker et al., 2007) were used. The collected data were analyzed using Pearson's correlation test and structural equation modeling with the help of Amos24 and SPSS22 software. The findings of this research indicated that the relationship between traumatic childhood experiences and executive functions is significant. Also, the model of the mediating role of emotional processing in the relationship between traumatic childhood experiences and executive functions had a favorable fit. Bootstrap results also indicated the impact of traumatic childhood experiences on executive functions through the mediating role of emotional processing. As a result, it can be said that the emotional processing variable has a significant mediating role in the relationship between childhood traumatic experiences and executive functions. Therefore, it is necessary to act through information and awareness in the field of negative cognitive consequences of traumatic childhood experiences to prevent or intervene early in this field.

The present study was conducted with the aim of combining the researches conducted in the field of determining the effectiveness of educational and therapeutic psychological interventions on the cognitive flexibility of Iranian children and adolescents with the meta-analysis method. The statistical population of the present analysis is the available researches related to the effectiveness of educational and therapeutic psychological interventions on the flexibility of children and adolescents, which were published between 2013 and 2023. Based on the defined entry and exit criteria for primary studies and sensitivity analysis, 61 effect sizes from 43 primary studies were analyzed by CMA software version 2. The findings showed that the summary effect size of the random model was equal to 1.964, which is statistically significant and indicates the positive effect of educational and therapeutic psychological interventions on cognitive flexibility. Also, the results showed that there is a significant difference between the types of intervention, research tools, and the age and gender of the subjects. As a result, considering the desired effectiveness of providing educational and therapeutic interventions in order to improve the cognitive flexibility of children and adolescents, it is suggested that it should be considered more and more by those involved in the education of children and adolescents in order to benefit from its potential benefits throughout life.

The present study employs structural equation modeling to assess the fit of a structural model encompassing obsessive beliefs grounded in executive functions, with emotion regulation as a mediating factor within a non-clinical population. The sample comprises 400 adults aged 20 to 50 in Tehran, selected from the general population via the available sampling method. The data collection instruments encompassed the Obsessive Beliefs Questionnaire (OBQ), the Executive Functioning Questionnaire -Adult Version (BRIEF-A), the Cognitive Emotion Regulation Questionnaire (CERQ), and the Behavioral Emotion Regulation Questionnaire (BERQ). The analysis of structural model fit indices revealed that they all fell within an acceptable range, thus affirming the suitability of the research's structural model. According to this model, executive functions exhibited significant effects on adaptive emotion regulation and maladaptive emotion regulation with standard coefficients of -0.45 and 0.76, respectively. Furthermore, adaptive emotion regulation with a standard coefficient of -0.10 and maladaptive emotion regulation with a standard coefficient of 0.63 were significantly impacted obsessive beliefs. To evaluate mediating relationships, the bootstrap test results were examined. It was found that the effect of executive functions on obsessive beliefs, mediated by maladaptive emotion regulation, was significant with standard coefficient of 0.478 at the p < 0.01 level. However, the effect of executive functions on obsessive beliefs, mediated by adaptive emotion regulation, was not significant with a standard coefficient of 0.045 at the p < 0.05 level. The findings of the study hold practical implications for the prevention of obsessive belief development and the alleviation of obsession-related suffering.

Introduction: The present study was conducted to determine the effectiveness of transcranial direct current stimulation on social-informational conformity, considering the moderating role of gender. Method: Two groups (male and female), each group consisting of 24 people aged 18-30, were selected from Tabriz University students' society with a non-random and available sampling method. The current research design was a semi-experimental type with a pre-test and a post-test. In the pre-test stage, the social-informational conformity computerized task was implemented. Then, two sessions (each, 20 minutes) of transcranial direct current stimulation were applied. In the post-test phase, the same social-informational conformity task was performed. Finally, the findings were analyzed with repeated measures variance analysis and covariance analysis in SPSS version 24 software. Findings: The amount of social-informational conformity increased in both groups after applying transcranial direct current stimulation, and gender did not moderate the effect of this stimulation. Conclusion: Transcranial direct current stimulation has the same effect on conformity in both men and women. Also, cathodal stimulation of the ventromedial prefrontal cortex significantly increases the tendency for social-informational conformity in women and men when the participants' initial decision is different from the majority. Since cathodal stimulation reduces neuronal firing, cortical excitability, and motor-evoked potentials, it is reasoned that the reduction of vmPFC stimulation enhances the conformity behavior in people.

Introduction: This research was conducted with the aim of investigating the effect of uncertainty about others on conformity to prosocial behavior and the moderating role of gender and need for closure. Method: The statistical population of this study included men and women aged 20 to 40, which 120 subjects were selected through available sampling. A computer-based task in the form of a profitable game was designed using the Psychopy software to assess the prosocial behavior of the participants in different conditions of ambiguous stimulus exposure. Also, a short form of the Need for Closure Questionnaire by Reiss and Pilati (2020) was employed. The data were modeled using mixed models' methods in the R software. Results: In the modeling of the results of the research, the most favorable model showed that exposure to an ambiguous stimulus with a coefficient of 0.84 and the variable of the need to be closure with a coefficient of 0.54 led to an increase in conformity behavior in conformity of prosocial behavior. and the need to closure has a moderating role. Also, gender was not included in the optimal model and its effect was not significant. Conclusion: The results of the current study showed that exposure to ambiguous conditions causes an increase in conformity of prosocial behavior and that the need for closure has a positive role in this effect; however, gender does not play a role in this effect.

Introduction: The purpose of this research was a comparison of emotional working memory capacity in monolingual (Persian) and bilingual (Armenian-Persian) girls aged 7 to 9 years and 11 months and 29 days. Method: The statistical population of the current study included elementary school girls aged 7 to 9 years and 11 months and 29 days in the second semester of the 1401-1402 school in Tehran. The statistical sample included 30 monolingual students (Persian) and 30 bilingual students (Armenian-Persian) who were selected among the first to third- grade students of public schools and the available sampling method. In this research, the information was processed by children's emotional working memory capacity test and number capacity test (reading forward and reverse digits). The data were analyzed by the Kolmogorov Smirnov, the Independent Samples test to compare two groups and logistic regression in IBM SPSS STATISTICS21 software. Findings: The results showed that there is a significant difference between monolingual and bilingual children in the age groups between 7 years and 6 months and 8 years and 11 months and 29 days (p<0.05), but no significant difference was observed in the other age groups (p>0.05). Also, the aging (by one unit) reduces by about 80.5% in the difference between the scores of monolingual and bilingual people (p>0.01). Conclusion: According to the obtained results, it can be concluded that bilingualism is more effective than monolingualism in the capacity of emotional working memory and cognitive-emotional functions of children, and it should be taken into account in educational and business planning.
