This study aimed to compare the effectiveness of yoga training with emotion regulation training on students' working memory and cognitive flexibility. The research methodology was quasi-experimental designed as pretest and posttest with control and follow-up groups. Entire second-grade female high schoolers in the 2nd District of Tehran, during 2018-19 academic year, constituted study’s statistical population, of whom 54 students were chosen using cluster random sampling method, and randomly assigned into three groups. The pretest of N-back and Denis and Wenderval’s cognitive flexibility (2010) was administered for all three groups; and then the experimental groups received yoga training and emotion regulation intervention and finally posttest was implemented followed by 4-week follow-up test. Data analysis used by analysis of variance with repeated measurements exhibited that, both trainings significantly resulted in an increase in components of Different recognition and recognition time of working memory and cognitive flexibility (p≤/001). Yoga training had more effect on the component of different recognition and psychological flexibility than on emotional regulation training (p≤/001), while the impact of both two interventions had not a significant difference on the component of recognition time.

This study aimed at determining the effect of forehead cortex electric current stimulation on inhibitory control and working memory in people with attention deficit and hyperactivity disorder (ADHD), using TDCS device. The method used was quasi-experimental research with pretest-posttest control group design. The participants were 24 children with attention deficit and hyperactivity disorder aged 7-11 who referred to Baqiyatallah Hospital in 1397. Children were randomly divided into experimental (n = 12) and control (n = 12) groups. The experimental group was intervened in 10 sessions, 3 times a week, and each session was 20 minutes. Assessments were performed in 3 steps, a day before the intervention, and a day after the intervention ended, and finally at the follow-up phase, two months after the intervention was accomplished. Go/no Go and N-back tests were used to evaluate inhibitory control and working memory, respectively. A repeated measurement method was applied to analyze the data. Findings revealed that brain electric stimulation program improves working memory and inhibitory control in children with attention deficit hyperactivity disorder. Therefore, brain electric stimulation program can be used to enhance the working memory and inhibitory control of children with attention deficit hyperactivity disorder.
