The present study was conducted to investigate the effectiveness of transcranial direct current stimulation (TDCS) on the improvement of mental health of divorced women referred to counseling centers. The research method was semi-experimental and pre-test-post-test design with control and follow-up groups. The statistical population of the research included divorced women who were referred to counseling centers in Ardabil city. Among them, 30 people were selected by convenience sampling and randomly assigned to two experimental and control groups. The tool used in the research was Symptom Checklist-90-Revised (SCL-90-R). The intervention was carried out using a transcranial direct current stimulation device on the experimental group members for 10 consecutive sessions (20 minutes each session) by placing the anode in the F3 section and the cathode in the FP2 section.The data were analyzed using the statistical method of analysis of covariance with repeated measures. The findings of the research showed that there is a significant difference between the two experimental and control groups in terms of mental health and its subscales, including depression, anxiety, obsessive-compulsive disorder, aggression, and psychosis (P<0.001). these results indicated the effectiveness of transcranial direct current stimulation on the mental health of divorced women. Overall, the research findings highlight the role and importance of TDCS treatment in improving mental health. According to the results, it seems that the left frontal cortex plays an important role in people's mental health. Therefore, with the electrical stimulation of this part of the brain, it can help a lot to improve people's mental health.

Overcoming problems and solving them, and maintaining mental and physical health in life, is very important. By improving cognitive abilities and increasing the processing speed of the mind, it is possible to improve the quality and health of life throughout life. The main goal of this research is to investigate the effect of transcranial direct current electrical stimulation (tDCS) on cognitive flexibility, problem solving and brain processing speed in students. This research was conducted as a semi-experimental design with a pre-test and post-test and a one-month follow-up phase. In this research, 30 people were selected as a sample using the purposeful sampling method and they were randomly divided into two experimental and control groups. The tDCS test group was subjected to electrical stimulation during two weeks and in 10 sessions, with a current intensity of 2 milliamps and for 20 minutes. At first, after finishing the stimulation program, and also one month later, tests of cognitive flexibility, problem solving and brain processing speed were taken from both groups and the results were analyzed using covariance test with repeated measurements. Based on the obtained results, it was observed that the difference between the groups is significant and indicates a positive and significant effect of intracranial direct current stimulation on cognitive flexibility, problem solving and brain processing speed. Also, according to the one-month follow-up phase, the mentioned effects are stable.

Introduction: The aim of this study was to evaluate the effectiveness of behavioral self-regulation on working memory, attention deficit and hyperactivity in children. Method: This research was performed experimentally with a pretest-posttest design with an experimental group and a control group. The statistical population included all children aged 7 to 12 years with attention deficit hyperactivity disorder who referred to counseling and psychology centers in Tehran's District 5 in the academic year 2019-2020, and were treated with Ritalin. Sampling was done by simple random method. Then, among the 40 people who received the most symptoms of attention deficit hyperactivity disorder and the lowest score in working memory, they were randomly divided into experimental and control groups. The experimental group separately participated in 8 weekly sessions of 60 minutes of research intervention and the control group remained on the waiting list. The research instruments included the Pediatric Symptoms Questionnaire (CSI-4) and the Work Memory Scale of Aloy et al. (2008). Statistical data were analyzed using multivariate analysis of covariance. Results: The findings indicate that self-regulatory behavioral interventions are effective on working memory and reducing the symptoms of attention deficit hyperactivity disorder in children. Conclusion: Behavioral self-regulation skills training had a significant effect on working memory of ADHD children.

Aim: Neuropathic pains are common complications of chronic diabetes that have a negative effect on patients' mood. The present study, however, was conducted with the aim of determining the pure and combined effect of M1 and F3 anodic tDCS on reducing psychological distress in type 2 diabetes patients with neuropathic pain. Method: The study is a four-group double-blind randomized clinical trial. The statistical population of the study was all patients aged 45 to 65 years with type 2 diabetes who were members of the Bonab Diabetes Association in the winter of 2021 and spring of 2022, identified by specialists as having neuropathic pain. The research sample was 48 people selected in a purposeful way and according to the inclusion and exclusion criteria. Then, the subjects were randomly assigned to 4 groups. Patients in 4 groups received their own interventions for 12 sessions, three times a week. The data collection tool was the 42-item depression, anxiety, and stress scale (DASS). Results: According to the results, the average psychological distress in the post-test, 1-month follow-up, and 3-month follow-up phases, compared to the pre-test phase, was significantly reduced. However, there was no difference in the mean psychological distress scores between the other phases (post-test, 1-month follow-up, 3-month follow-up). That is, even up to the 3-month follow-up phase, the effect of the interventions remained. Conclusion: Therefore, the application of transcranial direct current stimulation, considering its therapeutic potential, can be expanded in people with diabetes.

Aim: The purpose of this study was to determine the effects of audio-visual modeling on mu rhythm suppression in basketball lay-up shot. Method: For this purpose, 13 physical education students of Shahid Rajaee Teacher Training University participated voluntarily in this study. Order of presenting visual and auditory stimuli was counter-balanced among participants. Participants were randomly divided into two groups: the first group, observed the visual stimulus model first, then received the auditory stimulus, and the second group received the visual stimulus after the auditory stimulus and eventually presented the audio-visual stimuli. Brain waves were recorded by EEG in three conditions, presenting visual and auditory and audio-visual stimuli and were transformed to quantitative data by Neuro-guide Software. Results: Results of two-way repeated measures ANOVA in a 3 (condition) × 3(brain area) design revealed that main effect of the brain area was significant, results of Bonferroni post hoc test for brain area main effect showed that the mu rhythm was significantly more suppressed in Cz compared to C3 brain area (P=0.014). In addition, the results also showed that the mu rhythm in CZ was significantly more suppressed than C3 in both visual (P=0.025) and audio-visual (P=0.014) stimuli conditions, however, there were no significant differences between the mu rhythm Suppression in auditory condition among three brain areas. Conclusion: Finally, results confirmed that the integrity of the audio-visual stimuli causes further in mu rhythm suppression and mirror neurons activation.

Methods: 20 male elite freestyle wrestlers (age: 22.36±2.38) participated in this study and were randomly assigned to experimental (mindfulness-based intervention) and control groups. Two official competitions were used as pre-test and post-test. Perceived stress was measured by the short version of Perceived stress scale. Awakening and competitive levels of salivary immunoglobulin A were evaluated using the ELISA method. The experimental group participated in 8-week mindfulness intervention (two sessions per week). Data were analyzed using repeated measures ANOVA and independent t-test. Results: The results showed that after the 8 weeks of intervention, perceived stress was reduced in the experimental group. Hoewer, the awakening and competitive levels of immunoglobulin A did not show a significant difference compared to the control group from pre-test to post-test. Conclusion: In general, it can be concluded that mindfulness intervention can be a strategy to reduce the perceived stress in elite wrestlers during the competition period. Future studies with larger samples with other disciplines can better demonstrate the comprehensiveness of the results.

Background: Nowadays, the study of neurological infrastructure of personality traits has a special place in neuropsychological research. According to Eysenck, the correlation between personality and behavior is the result of individual differences in the brain function. The purpose of the present study was to investigate the frontal EEG asymmetry according to neuroticism and extraversion dimensions.Methods: The statistical population of the present study was all male students of Payame Noor University of Tehran, who studied in the academic year of 1963-96. Based on the final scores of distribution in two dimensions of extroversion and neuroticism, four groups (extroverts, introverts, neuroticism and emotional stability) with 25 subjects were selected. The subjects completed the Eysenck Personality Questionnaire- Revised, Waterloo Handedness and footedness Questionnaires-Revised, and their eyedness was assessed, then the electrical activity of the brain of the subjects was recorded through EEG from different points on the scalp. Results: The findings of the study show that there is no significant difference between the four groups in the right frontopolar (FP2), right middle frontal (F4), right lateral frontal (F8) and right frontal cortex (RF) in alpha activity. There is a significant difference between the left frontopolar (FP1), left middle frontal (F3), left lateral frontal (F7) and left frontal cortex (LF) between the four groups (P<0.01); as alpha wave activity on left regions in neurotic and introverted individuals is more than emotional stable and extroverted subjects. Conclusion: In general, the findings of the present study strengthen the relationship between personality dimensions and frontal EEG asymmetry.

Background: Executive functions in primary school children are very important because they can have a decisive role in improving children's performance in school and even for their future. Aims: The purpose of this study was to investigate the effect of computer games and motor games on the executive functions of primary school students. Methods: The current research was a semi-experimental. The statistical community was all the 7-9 years old primary school students of Babol city in 1401. To select the sample, three schools were selected through random sampling. 15 people from each school were randomly divided into three groups (movement games, computer games and control). The research tool was BRIEF Executive Functions Questionnaire. Movement and computer group programs were conducted for 12 sessions (4 weeks and three sessions per week). The control group continued their usual programs. Analysis of covariance test and Bonferroni's post hoc test were performed at the level of p<0.05. Results: The results of the analysis of covariance showed that by considering the pre-test scores as the control variable, the training interventions (computer games and movement games) caused a significant difference between the experimental groups. Based on the results of Bonferroni's post hoc test, the difference in executive function variables between the two experimental groups and the control group was significant (p<0.001) but non-significant with each other (p>0.05). Conclusion: motor and computer games can be used as a practical option in order to improve children's executive functions.

The aim of this study is to develop and validation a training program based on maternal scaffolding to improve executive attention (inhibition, shifting, and updating working memory) in pre-school children. This study has been carried out in three phases. Within the first phase, upon reviewing previous projects, the dimensions and components of parental scaffolding that relevance to executive functions were identified. In the 2nd phase, under documentary analysis methodology, a training program for improve of the executive functions in pre-school children, was presented. The components of parental scaffolding that relevance to executive functions, were merged to games and activities of this program. In the third phase, the prepared program sought validation. Based on the plan of this project, a single group pursued pre-test, first post-test, and second post-test assessments. The participants included sixteen mothers with 3-6-year-old children, who participated in the course with their children, and were selected voluntarily. The measurement tools applied in this study were Day/Night Stroop task (Gerstadt et al.,1994), flexible item selection task (Jacques & Zelazo, 2001) digit span task (Wechsler, 2003). The results showed that this program was highly effective for improve of three dimensions of executive functions, and this effectiveness has been maintained constantly. Overall, based on this study, mothers can attain a more accurate perception of the cognitive development of their children and assist the cognitive growth of their children upon performing the games and activities covered by this program; while concurrently understanding their role in this development.

The sample included 45 children between 7 and 10 years old with brain tumors selected from Mahak Hospital purposefully and by considering the inclusion and exclusion criteria. The subjects were randomly replaced in 3 groups of 15 people (group 1: cognitive rehabilitation; group 2: cognitive rehabilitation with play therapy; group 3: control group). The experimental groups received relevant interventions in 8 sessions, and the control group did not receive any intervention. The pre-test, post-test and 1-month follow-up of the participants of all 3 groups were conducted with the Executive Function questioner (BRIEF). In order to analyze the data, split-plot ANOVA design (SPANOVA) with spss21 software was used.Findings: According to the results, the deficit of executive functions in children of both experimental groups was reduced compared to the control group and was stable in the follow-up. Conclusion: The result showed these interventions can be used for children with brain tumors. Of course, the use of rehabilitation therapy integrated with play therapy is more suitable for improving the cognitive skills of children with brain tumors.

Objective: The present study was conducted with the aim of investigating the effectiveness of mindfulness training based on virtual reality on improving the cognitive regulation of emotions in students with specific learning disabilities. Method: The research was semi-experimental with a pre-test, post-test and a two-month follow-up design. The statistical population was female students with math learning disorders in Kermanshah learning disorder centers. A cognitive emotion regulation questionnaire was administered to students, and among those who met the criteria for entering the research, 24 students were selected by purposeful sampling and randomly placed in two groups of 12 people, experimental and control. The experimental group underwent 10 sessions of mindfulness training based on virtual reality, but the group did not receive the training certificate. One week after the last training session, a post-test was conducted and two months later, a follow-up test was conducted. Data were analyzed using repeated measures analysis of variance. The results showed that mindfulness training has improved students' cognitive emotion regulation (P<0.001) and these effects were stable in the follow-up phase. Since mindfulness training based on virtual reality improves the cognitive regulation of these students' emotions, this efficient method can be used to improve the cognitive regulation of these students.
