Abstract
Aim and Background: The present study aimed to investigate the efficacy of executive functions training (response inhibition) on the attention of preschool children with developmental coordination disorder in Isfahan city, Iran. Methods and Materials: The study population consisted of all the preschool children (5-6 years old) with developmental coordination disorder. Purposive sampling method was used. The subjects were three preschool children who had a diagnosis of developmental coordination disorder symptoms. Data collection tools included: (NEPSY neuropsychology test) neuropsychology test, Conner’s parent rating scale, Wechsler intelligence scale for children, basic motor ability tests and clinical interview. A single-subject method with multiple baseline design (MBD) research methodology was used too. The intervention started right after the baseline condition and 10 individual sessions of response inhibition executive functions training was given to them afterwards. Findings: The results of the data chart analysis based on descriptive statistics and visual analysis indices revealed that the intervention was effective on the three participants (respectively PND 100%, 90% and 70% for test number one, two and three). Conclusions: The results of the present study showed that by response inhibition executive functions training, the rate of attention deficit can be reduced and the rate of academic performance can be improved.

Abstract
Aim and Background: Chronic use of opiates has been associated with a wide range of cognitive deficits, involving domains of attention, inhibitory control, planning, decision-making, and memory. Therefore, the main aim of this research was the comparison of executive functions in heroin dependents and patients on methadone therapy with a control group. Method and Materials: The retrospective research method was used in the current study. Purposeful sampling method was used in methadone and heroin groups, but control group participants were selected randomly. Statistical population in this study consisted of heroin dependents and methadone users, in Isfahan city in 2012, who had been referred to medial, rehabilitation centers, and psychiatric clinics. Finally, 75 patients were selected in three groups [methadone (n = 25), heroin (n = 25), and control groups (n = 25)] according to the criteria of drug abuse or dependence in DSM-IV-TR. Then, they were evaluated based on the Tower of London and Stroop neuropsychological Tests. Findings: Results of analysis of variance show that the control group had a better performance in the Tower of London and Stroop tests in comparison with heroin dependents and methadone users groups (P ≤ 0.05). However, there were no significant differences between heroin dependents and methadone users groups. Conclusions: Heroin dependency and methadone use, probably, causes prefrontal cortex and executive dysfunctions, and neurological disturbances in frontostriatal systems. According to these findings, we can design professional cognitive rehabilitation programs to rehabilitate patients in their personal, occupational, and social life.

Abstract
Aim and Background: Executive functions are the most important factors that influence students’ mathematics disorders. With the technological advances in the field of education it is possible to use a computer training program to evaluate and treat this disorder. Method and Materials: In this quasi-experimental research we selected 10 female elementary students of learning disorder centers in Tehran with mathematics disorder, and 10 normal students. The two groups were matched in age and intelligence. We tested all of the students with Key Math and executive functions tests. Students with mathematics disorders received the working memory training for 20 sessions in 7 weeks. Samples of these researches were retested using executive functions test. In order to compare the executive functions in students with and without mathematic disorders Student’s t-test was used to analyse data. Findings: There were differences between executive functions in students with and without mathematics disorder. Moreover, working memory training had a significant effect on the executive function of students with mathematics disorder. There were more significant difference in average in the math disorder group in comparison to the control group. In addition, there was a significant difference in effect of executive functions pre- and post-intervention, and in follow-up. Conclusions: The results of the current study showed that the working memory computer assisted program caused improvements in executive functions of students with mathematics disorders.

Abstract
Aim and Background: So far, several therapeutic approaches, both pharmacological and non-pharmacological, have been used for patients with Attention Deficit Hyperactivity Disorder and researchers are trying to determine the effectiveness of each of these approaches. Therefore, the aim of this study was to compare the effectiveness of drug therapy, neural feedback and integrated psychological interventions (parent education, play therapy and cognitive education) on behavioral problems of ADHD.
Methods and Materials: The research method was quasi-experimental and the pre-test-post-test-follow-up and control group design. The statistical population included all children aged 9 to 12 years in Hamedan. Sampling method was Purposive. The psychotherapy group received medication daily for 12 weeks. The neural feedback group received 24 sessions of 45 minutes twice a week. The group of integrated psychological interventions received training for 24 sessions. Participants were assessed using the Swanson, Nolan, and Pelham Fourth Edition Scale to assess the clinical signs of ADHD, the College Neuropsychological Test to measure executive function, and the Rutter form Behavioral Problems Self-Report Scale. Multivariate analysis of covariance and multivariate analysis of variance were used to analyze the data.
Findings: The results showed that combined psychological interventions were more effective in the behavioral problems variable and all its components compared to drug therapy and neurological feedback, which was also significant in the quarterly follow-up (p≤0.001).
Conclusions: It seems that integrated psychological interventions can be an effective and lasting treatment for behavioral problems in children with ADHD and can replace other therapeutic approaches such as medication and neurological feedback.

Abstract
Aim and Background: Today, children's aggression is one of the most common and one of the important reasons for their referral to psychotherapists. The aim of this study was to compare the effectiveness of story therapy and music therapy on the executive functions of aggressive female students.
Methods and Materials: In this quasi-experimental study, 45 aggressive students were randomly selected from among elementary school female students in Karaj in the academic year 2020-2021 and were randomly divided into two experimental groups and one control group. The research instruments included primary school children aggression questionnaires, Wisconsin test, continuous performance test and Stroop test. The experimental groups underwent story therapy in 11 sessions and music therapy in 8 sessions. Data were analyzed by multivariate analysis of covariance.
Findings: There was a significant difference between the effectiveness of story therapy and music therapy on executive functions (p <0.001) of aggressive female students. The mean scores of executive functions in the post-test of music therapy were significantly higher than the mean scores of the story therapy group and the control group (p <0.001).
Conclusions: Story therapy and music therapy have an effective role in improving the executive functions of aggressive female students. Also, music therapy has a greater effect on increasing performance indicators (cognitive flexibility, sustained attention and inhibition) of aggressive female students than story therapy. Therefore, it is suggested that these treatments be performed by specialists in these fields to help aggressive students in educational and therapeutic environments. The results of this research can have many educational implications.

Aim and Background: The present study was conducted to investigate the effectiveness of neuropsychological rehabilitation of executive functions on students' memory.
Materials and Methods: This research is semi-experimental using a computerized Wechsler working memory intelligence test prepared and compiled from the Farakhnai subscale of the Wechsler intelligence scale, which was used to measure working memory. The statistical sample consisted of 20 high school students who were randomly selected from high school boys in Varamin in the academic year of 1400-1999 in public high schools in mathematics, experimental and human subjects. The subjects were in two control groups (10 subjects) and the experiment (10 subjects) were randomly replaced.
Findings: Neuropsychological rehabilitation of executive functions is effective in improving students' auditory memory/forward repetition, auditory memory/reverse repetition, visual memory/forward repetition, visual memory/reverse repetition, auditory memory, visual memory, and auditory memory span. Visual memory of students is not effective. Also, there was a statistically significant increase in the average score of all dimensions of working memory from the time before the intervention to the follow-up period, and only in the visual dimension / reverse repetition of the average before the intervention (p≤0.001). There was no significance between the two means (p≥0.001).
Conclusion: In general, the results show the effectiveness of neuropsychological rehabilitation of executive functions on students' memory
