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.

Purpose: Considering the importance of job motivation in educational jobs, the present study was conducted to construct and evaluate the psychometric properties of teachers' job motivation questionnaire. Methodology: The present study was applied in terms of purpose and descriptive-correlational in terms of implementation method. The study population was elementary school teachers in Tehran in 2019-20, which the sample size was estimated 400 people based on Cochran's formula and were selected as a sample by multi-stage cluster random sampling. Data were collected by a researcher-made job motivation questionnaire (49 items) and analyzed by exploratory factor analysis and structural equation modeling in SPSS-22 and AMOS-24 software. Findings: The results showed that teachers' job motivation had 2 factors and 9 components; so that the external factor of job motivation includes four components of school environment, payroll system, leadership style / managerial support and performance appraisal and reward and the internal factor of job motivation includes five components of in-service training, work and cognitive interests, effective communication, perfectionist thoughts and selection and the factor loading of both factors and all nine components were significant at the confidence level of 0.99. Also, the content validity of the instrument was confirmed by experts and the convergent validity of the instrument was confirmed by the correlation coefficient of the score of each factor or component with the total score of the instrument. In addition, Cronbach's alpha reliability for the whole instrument was 0.92, external factor of job motivation 0.85, internal factor of job motivation 0.89 and components of school environment 0.75, payroll system 0.66, leadership style / managerial support 0.91, performance appraisal and reward 0.65, in-service training 0.82, work and cognitive interests 0.90, effective communication style 0.81, perfectionist thoughts 0.83 and selection was 0.71. Conclusion: Teachers' job motivation questionnaire was a valid and reliable instrument. As a result, specialists and planners of the education system can use it to review and evaluate the current situation of teachers' job motivation and provide solutions to strengthen their job motivation.

Purpose: The purpose of this study was to design and test the structural model of the effects of life experiences, personality traits and thinking styles on the success of teachers with the mediation of job interests. Methodology: In order to achieve this goal, 234 teachers were selected using a cluster sampling method among high school teachers in Bojnourd city as the sample of this study. At first, their success rate was assessed by managers and students through a researcher-made questionnaire. Then Sternberg-Wagner Stress Thinking Styles Questionnaire, Five Factor Questionnaire, Short Form Personality Traits, Job Awareness Questionnaire and Researcher-made Life-Exercise Questionnaire were completed by the teachers. At first, the descriptive characteristics of the data from the research sample were examined. In the next step, based on the path analysis method, the research model was extracted based on the relationships between the variables and finally, the fit of the extracted model with the experimental data was evaluated using the structural equation modeling method. Findings: The results indicated that the personality traits of psychosis, extroversion and direct consistency, and personality trait of conscientiousness indirectly through external job interests, have a significant effect on the prediction of teachers' professional success. Also, Kurds of thinking styles, cognitive thinking, forms of thinking styles, group thinking, levels of thinking styles, holistic thinking, and the domains of thinking styles, external thinking, and the forms of thinking, thinking, and marital styles are also Both indirectly and indirectly through interpersonal and interpersonal interests, and the work of thinking styles, peer-to-peer, indirectly through external job interests, coefficients have a significant effect on the prediction of the professional success of teachers.
