Introduction: The present study was conducted to evaluate the effect of brand advertising on the brain wave pattern of interested and unproductive consumers of Nike brand. Method: This study was a causal-comparative study. The statistical population of the present study was male students of Tabriz University in the period of 2016-17. At first, using brand-name questionnaire and researcher-made questionnaire, brand-related students were identified as interested and uninvited students, and were randomly selected from 20 individuals and 20 uninitiated. Then the video clip that was used for Nor Marketing has been broadcast and at the same time a small amount of electroencephalography has been recorded in the delta, theta, alpha and beta frequency bands. Data were then analyzed by multivariate analysis of variance and all stages were calculated by SPSS software version 19. Findings: The results of the research showed that there is a significant difference between those who are interested and not interested in advertising brand. There was a significant difference between the two groups in the delta, theta, and alpha frequencies (P 0.05). Conclusion: Based on the findings of this research, it can be said that understanding the early functions of the human brain in the study of consumer purchasing behavior is possible using electrophysiological devices.

Introduction: Risky behaviors are one of the most important causes of mortality in adolescents. The purpose of this study was to investigate the pattern of structural relationships between brain-behavioral systems activity, process emotion regulation strategies and risky behaviors. Method: 410 students (210 females and 200 males) were selected from the students of Karaj using multistage cluster sampling and assessed by adolescents’ risky behaviors questionnaire, Jackson Factor Scale, and emotional ordering questionnaire. After collecting data, Lisrel software and SPSS software were used for data analysis. Findings: The findings show that BAS, BAS and FFFS components have a direct effect on risky behaviors. Additionally, the reappraisal of emotional experiences by reducing the effect of the activity of brain-behavioral systems in the risky behaviors of adolescents has a mediator role, while the suppression of emotional experiences by mediating the activity of brain-behavioral systems in high-risk behaviors of adolescents has a direct mediator role. Conclusion: In general, the findings of this study support the role of physiological bases of personality and emotion regulation strategies in the incidence of risky behaviors.

Introduction: Substance abuse disorder is a chronic disease which has adverse effects on various psychological, social and physical aspects of individuals' lives. In this respect, examining the psychological variables associated with substance abuse disorder can help to better understand this disorder and effectively manage and reduce opioid craving in patients. The aim of the present study was to investigate the moderating role of early maladaptive schemas in the relationship between brain activation and inhibition systems; and opioid craving. Method: In this descriptive-correlational study, a sample of 150 male patients with substance abuse disorder were selected by purposive sampling method and considering exclusion and inclusion criteria. The participants were asked to fill out the short form of Young Schema Questionnaire (YSQ-SF), Behavioral Activation and Inhibition Systems Scale (BAS/BIS), and Heroin Craving Questionnaire (HCQ-45). Stepwise regression was used to analyze the data. Results: Results indicated that brain activation and inhibition systems were respectively positively and negatively associated with opioid craving (p<.05). Additionally, early maladaptive schemas were found to be positively correlated with craving (p<.01). No moderating role was found regarding the early maladaptive schemas in the relationship between brain activation and inhibition systems; and opioid craving. Conclusion: According to the findings, brain activation and inhibition systems are one of the predicting factors of the opioid craving. Thus, the present study suggests that brain activation and inhibition systems should be taken into account in developing intervention and relapse prevention programs.

Introduction: Major depression is the most common psychiatric disorder and in the world has the greatest impact of all biomedical diseases on disability. The purpose of the present study is comparing the expression of dopaminergic DRD3 and DRD4 receptors in patients with major depression and healthy Individuals. Methods: The population of this study was, all depressed patients admitted to the clinical psychologists. The method is causal-comparative study. The research sample includes of 62 depressed patients (28 male and 34 female), with the random sampling of depressed patients referred to the clinics, to be selected, and 60 healthy individuals(30 male and 30 female) as comparison group. After the informed consent.Evaluate the relative expression of gene DRD3 and DRD4, using measured by quantitative Real-Time RT-PCR and SYBER Green used. Research data was analyzed using the T-Test, SPSS and Excel software. Results: Results showed that DRD3 gene in patients compared to healthy subjects had greater relative expression(p value<0.001),but the D4 gene expression in the two groups showed no significant difference (p >0.05).The finding suggest that DRD3 gene seem to be important variables in depression, but DRD4genedoes not play a role in depression. Conclusions: The finding suggest that he DRD3 receptor gene seem to be an important variable in depression, which showed decreased expression of receptor DRD3,under the influence of this disease, which we can be used as a marker for to screen major depression disorder (MDD) correctly.

Aim: the most common of which is disordered reading or dyslexia This study investigated the effectiveness of Neurofeedback on Cognitive Deficits and visual–motor perception in the dyslexic students. Methods: Present research was a quasi-experimental Method with pretest-posttest and control group design. The population included 8 to 11 years old pupils with dyslexia in Tehran city. The sample consisted of 40 students with dyslexia that are selected and randomly assigned to two experimental and control groups(each group n = 20). Finally, the study was performed with 33 patients(16 in experimental group and 17 in control group). In this study the experimental group received sessionsof neurofeedback training First, given three times a week(for one month) and then twice a week(one month) for 45 minutes, while the control group did not receive this training. The instruments used in this study were the Tower of London software, Stroop, continuous operation test, n-back test and Bender-Gestalt visual-motor coordination . Data were analyzed using multivariate covariance analysis using SPSS version 20 software. Results :The results showed that Neurofeedback on Cognitive Deficits in terms of reduced time and increased total points in the Tower of London, committing and remove errorsand time in continuous operation test, and reduce the amount of time keeping, time incongruent, inconsistent error in Stroop test and correct response in n-back test(P˂ 0.05); and visual-motor coordination in terms of distortion, rotation, Lack of integration and repeatness is effective on dyslexic individuals(P˂ 0.01).A. Conclusion: ccording to the findings concluded that Neurofeedback is effective way to improve symptoms of dyslexic children.

Aim: The purpose of the present study is the effect of attention games on strengthening motor memory and inhibitory control of children with executive function disorders. Method: This study is a semi-experimental type with a pre-test and post-test design with a control group. The statistical population of this research included all 9-11-year-old boys in the primary schools of Kalibar city in the academic year of 2021-2022, with random sampling method available,Using the questionnaire of children's executive functions,30 students were selected and divided into two experimental (n=15) and control (n=15) groups by simple random method. In.In order to measure the effect of the executive function disorder questionnaire intervention (BRIEF–P), Wechsler Intelligence Scale for Children (1972) and Inhibitory Control Questionnaire Go/No Response Inhibitory Test (2005), Before and after training sessions were conducted on the control and experimental groups. Also, analysis of covariance was used to examine the effectiveness of intervention. Results:The results of one-way covariance analysis showed that there is a significant difference between the experimental and control groups in terms of motor memory and inhibitory control. Also, the executive functions of the experimental group compared to the control group, It has decreased from pre-test to post-test And this shows that the interventions have been effective And the severity of executive function disorder has decreased. Conclusion: Attention game can be used as an effective method along with other treatment methods to increase the consolidation of motor memory and inhibitory control of children with executive function disorders.
