Abstract
The purpose of this study is presentation the structural model of executive functions and extramarital relationship with mediating role of self­­­-control. The 210 samples were selected by convenience sampling. In experimental situation, for assessing executive function participants did computerized exams include: Stroop, Wisconsin, Go No Go and N- Back and completed self-control questionnaire of Tangney and attitudes toward infidelity scale of Whatley.  Data was analyzed through regression, structural equation modeling. Model has a suitable fit. Results shows that executive functions includes inhibition(-0/13), task switching(-0/13) ,working memory(-0/16)  and self-control(-0/10)had direct effect on extra marital relationship. Executive functions includes inhibition(-0/23), task switching(-0/11) ,working memory(-0/27) had indirect effect on extra marital relationship with mediation of self-control.
 
Does Faster Problem-Solving Improve Accuracy? Examining Cognitive Predictors in the Speed-Accuracy Trade-Off
Seyed Mohammad Saeid Sahaf,
Volume 12, Issue 4 (3-2025)
Abstract
Problem-solving is a goal-directed cognitive process that involves evaluating a problem and generating solutions to achieve desired outcomes. This skill is influenced by optimal timing regulation and self-control. The present study aimed to examine the role of total time, delay time, task difficulty, reaction time, and self-control in the speed-accuracy trade-off.
The sample consisted of 54 female students aged 10 to 11 years, with no history of illness, who were selected through convenience sampling from non-profit schools in Mashhad during the 2022–2023 academic year. The Tower of London task was used to assess accuracy in problem-solving, delay time, total time, and task difficulty, while the Flanker task was employed to measure self-control and reaction time. Multiple regression and mediation analyses were conducted in SPSS-26 to predict the influence of these variables on problem-solving accuracy.
The results indicated that total time (β = -0.769), delay time (β = 0.574), task difficulty (β = 0.388), and reaction time (β = -0.160) significantly predicted problem-solving accuracy. Specifically, an increase in total time led to decreased accuracy, whereas a longer delay before initiating problem-solving improved accuracy. Although the moderating role of self-control in the relationship between delay time, total time, and accuracy was not significant (p > 0.05), stepwise regression revealed that self-control was a significant predictor of accuracy (β = 0.157).
Thus, timing plays a crucial role in problem-solving accuracy. Allocating sufficient time for cognitive processing before responding can enhance performance, whereas prolonged problem-solving may reduce accuracy due to increased cognitive load or inefficient strategies. However, task difficulty and the nature of the task are also key factors in this relationship. The non-significant moderating effect of self-control may be attributed to its broader connections with other cognitive dimensions in participants.

Development of the relationship model of well-being, cognitive fusion and cognitive flexibility with the mediation of self-control in adolescents
Mis Maryam Mougouee, Dr Maryam Shahandeh,
Volume 13, Issue 4 (3-2026)
Abstract

Aim of the study was to develop a model of the relationship between wellbeing, cognitive fusion, and cognitive flexibility, with selfcontrol as a mediating variable. Research was correlational type, included 383 students selected through a multistage cluster sampling method. questionnaires were the Mindfulness Questionnaire, cognitive fusion, psychological flexibility, selfcontrol. The data were analyzed by Pearson correlation& structural equation modeling

The findings indicated relationship between mental wellbeing and its dimensions, cognitive flexibility, mediated by selfcontrol. Mental wellbeing through selfcontrol is related to cognitive fusion, and selfcontrol acts as a full mediator. Emotional wellbeing has relationship with cognitive fusion, and selfcontrol plays a full mediating role between social wellbeing, psychological well-being, and cognitive fusion

In conclusion, selfcontrol plays an important role in mental wellbeing, cognitive fusion, and cognitive flexibility among adolescents. Therefore, it is possible to support adolescents’ wellbeing, cognitive fusion, and cognitive flexibility through their selfcontrol


The effectiveness of cognitive-behavioral group therapy on self-control in people with depressive symptoms referring to counseling centers

Abstract
The aim of the present study was to determine the effectiveness of cognitive-behavioral group therapy on self-control in people with depressive symptoms referring to counseling centers. The present research method was applied in terms of purpose and in terms of type of research, it was a semi-experimental study with pre-test-post-test and control group. The statistical population studied in this study included all people with depressive symptoms referring to counseling centers in Qom in 1404. The subjects were selected using the convenience sampling method and were randomly assigned to an experimental group of 10 and a control group of 10. Initially, both groups responded to the research questionnaire (pre-test stage) and then for the first experimental group, an intervention program was implemented during the period of implementation of therapeutic interventions, which included 8 weekly sessions (cognitive-behavioral training) in groups for 60 minutes. The data collection tool was the self-control questionnaire of Tanji et al. (2004). SPSS version 27 software was used to analyze the questionnaire data, and the analyses were presented in two sections: descriptive statistics (mean, standard deviation, etc.) and inferential statistics (analysis of covariance test). Finally, it was concluded that cognitive-behavioral group therapy was effective on self-control in people with depressive symptoms referring to counseling centers.
