Aim: The present study has been performed to evaluate the gifted underachievement phenomenon on mathematics and compare neuropsychological skills profile of these students in groups with different levels of achievement. Methods: This study used a causal-comparative design. The study population includes all students of exceptional talents middle schools, in the academic year 2018/19. For this purpose, 36 male and female students were selected by the convenience sampling method and were studied based on their neuropsychological skills.To collect the data, the online version of Wisconsin Card Sorting Test, Corsi block-tapping test and Deary-Liewald reaction time task were used. Data were analyzed using multivariate analysis of variance. Findings: The results indicated there was a significant difference between neuropsychological skills in two groups in visual-spatial working memory, choice reaction time task and executive functions. Conclusion: According to the findings of this study, it can be concluded that underachiever gifted students experience more neuropsychological skills insufficiency than those gifted students with expected achievement. Therefore, in addition to paying attention to personality and environmental factors, evaluation of neuropsychological skills and application of appropriate neuropsychological interventions to prevent of the occurrence of gifted underachievement is recommended.

Introduction: Cognitive factors are the important correlates of dyslexia. Different researches show that these factors are impaired in children with dyslexia. Also, the studies believe in the dysfunction of fronto-temporo-occipital connection as a neural evidence of dyslexia. Neurofeedback by changing the functional connectivity or coherence of these regions could be useful in improving cognitive functions in dyslexic children. The present study aimed to determine the effectiveness of coherence neurofeedback training on phonological awareness and working memory in children with dyslexia. Method: In this single subject study, four dyslexic children completed twenty 30 minutes sessions of coherence neurofeedback training. Findings: The results showed improvement in the phonological awareness and working memory scores. Also, coherence values changed toward normal values after treatment. Conclusion: These changes indicate that dyslexia could be considered as a dysfunction in functional connectivity between specific brain regions and coherence guided neurofeedback seems to be capable of modifying these disturbances.

Introduction: Due to the important role of the brain and frontal area, especially the prefrontal cortex, in decision-making and also proposing defects in the functioning of frontal area in alexithymia, the aim of the present study was to examine the relationship between decision making styles and alexithymia. Method: In the present descriptive-correlational study, 257 university students (114 males and 143 females) were selected among Payam Noor Universities of Bonab and Tabriz by multistage random sampling and both Making Styles Questionnaire of Scott and Bruce (1995) and Twenty-Item Toronto Alexithymia Scale were administered among the subjects. The obtained data were analyzed by Pearson correlation test and multiple linear regression analysis. Findings: The results approved the predictive role of alexithymia in explaining the decision making styles of rational, avoidance, and intuitive. As predicted, increasing alexithymia leads to increasing rational decision making style, and decreasing avoidance and intuitive decision making styles. However, among three factors of alexithymia, concrete thinking was recognized as the only effective factor in rational decision making style, and difficulty in identifying emotions as the only effective factor on avoidance and intuitive decision making styles. Conclusion: It seems that there should be common points in the biological basis of decision making and alexithymia. This defect is most likely to occur in the prefrontal cortex function which is activated in ethical decision making, and defects in exchanging information from its right side to the left side.

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.

Introduction: The present study is a quasi-experimental study with an inter-intra subject design aimed to determine the effectiveness of combining acceptance and commitment-based therapy and mindfulness-based stress reduction therapy on anxiety sensitivity and perceived stress in people with type 2 diabetes. Method: The sample consisted of 45 patients with type II diabetes purposefully selected from patients referred to laboratories in Mahshahr city. After matching, the patients were randomly assigned to 3 groups of 15 patients and the experimental groups received their group interventions in 8 sessions of psychological therapy and 10 sessions of individual neurofeedback training and the control group did not receive any intervention. Pre-test, post-test, and 2-month follow-up were performed with Floyd et al.'s (2005) Anxiety Sensitivity Questionnaire and Cohen et al.'s (1983) Perceived Stress Scale. Results: According to the results of SPANOVA analysis, both ACT + neurofeedback and MBSR + neurofeedback were effective in post-test and follow-up stages to reduce anxiety sensitivity and perceived stress. But while the effectiveness of both interventions in reducing anxiety sensitivity was the same, for perceived stress, the effect of MBSR + neurofeedback, both in the post-test and in the follow-up phase, was significantly greater than the effect of ACT + neurofeedback.

The purpose of the current study was to examine the effect of transcranial direct electrical stimulation (tDCS) of the visual cortex on the acquisition and persistence of motor performance and working memory in children with developmental coordination disorders. In semi-experimental study with pre-test-post-test research plan and follow-up period of 1 and 42 days, 24 children with developmental coordination disorder were randomly selected, and randomly assigned to 2 groups of 12 tDCS visual cortex and sham stimulation. Participants in the pre-test performed 3 working memory tests and 10 throwing and catching skills. The intervention phase was performed for 5 consecutive days. Each day, electrical stimulation of the brain from the visual cortex (Oz anode and Cz cathode) and sham stimulation was performed. Participants performed 3 working memory tests and 10 throwing and catching skills. In the last session, post-test phase was performed. 1 day and 42 days after the post-test phase, short-term and long-term follow-up phases were performed, respectively. Data were analyzed with mixed analysis. The results showed that tDCS of the visual cortex significantly improved working memory and motor performance in children with developmental coordination disorders. Other results indicated the persistence of working memory and motor performance in children with developmental coordination disorders in short-term and long-term follow-up tests. In general, the results of the present study emphasize the effectiveness of tDCS in the vision area on motor performance and working memory in DCD children.

Aim:The purpose of this study is to investigate the relationship between brain-behavioral systems activity mediated by positive and negative emotions on social anxiety of students. Method: This study is correlational and structural modeling. In this study 409 students (200 males, 194 females and 15 unknown), from the University of Mashhad were selected by convenience sampling and three questionnaires: Social Anxiety Inventory (SPI) , Positive and Negative Affect Scale Panas (PANAS) and Brain-behavioral systems scale (BAS/BIS) in the form of self-report questionnaires. The raw data using structural modeling to estimate the maximum fit and were analyzed using LISREL software. Findings: The results indicate that the theoretical model is a good fit. Behavioral Inhibition System (BIS) directly associated with social anxiety as well as indirectly through negative emotions associated with social anxiety. As well as behavioral inhibition system associated with positive affect as significant negative relationship. Behavioral Aproach System (BAS) also indirectly through the positive affect, have an impact on social anxiety. The Fight/Flight/Freeze System (FFFS) through negative emotions associated with social anxiety. Positive Affect (PA) and Negative Affect (NA) both are significantly related with social anxiety.The impact of emotions (positive and negative affects) between path of brain-behavior systems and social anxiety, is important. Conclusion: High levels of negative affect in person, or low levels of positive affect, can be a sign to predict social anxiety.

Aim: The purpose of this study was to determine the effect of electrical stimulation of the brain from the skull on the memory of students with special learning disorder. Method: The present study was a semi-experimental pre-test-post-test with control group. To this end, the sample was selected through a sampling method from among students with learning disabilities who were eligible to participate in the study. Twenty people were selected and randomly divided into two experimental and control groups. The geometric image analysis of Andre-Ray (1942) was used to measure memory variables in the form of pre-test and post-test. The F3, F4 students in the experimental group were brainwashed in 10 sessions, while the control group students were only stimulated by the same conditions. The protocol in this study was a two-way stimulation of the left and right DLPFC area, which was performed in 2 15-minute intervals. Findings: In order to test the research hypothesis, in other words, generalization of the results of the sample to the statistical population of the study, one-way covariance analysis (ANCOVA) was used. Conclusion: The results showed that there was a significant difference between the two experimental and control groups in memory improvement (P <0.05 and F = 29.66). From the results, it can be concluded that the electrical stimulation of the brain from the tDCS skull is effective on the memory performance of students with special learning disabilities.

Introduction: The present study has been done with aim to investigate the effectiveness ofCognitive behavioral group Play therapy(CBPT)and transcranial direct current stimulation(tDCS)On executive function of working memory and response inhibition of children with (ADHD).Methods:In this quasi-experimental study with pre-test and post-test and control group,49 boys ADHD 6 to 11 years old were selected by Convenience Sampling method and from two schools in Islamshahr.In the following,By doing Stanford Intelligence Test and Conner’s Parent,13 people were excluded due to absence of entry criteria.The remaining 36 boys were randomly assigned into groups of intervention and control (each group included 12 subjects).Then, tests of N-Back for measures working memory and Go-No-Go was used for measures response inhibition Before and after interventions.Interventions included CBPT 8 sessions of 60 minutes and tDCS included 10 sessions of 10 minutes with intensity of 1 mA .Data were analyzed by Software SPSS version 23.Findings: After the removal of the effect of pre-test was determined that there was no significant difference between the intervention and control groups in the working memory scores(in the number of correct responses and action speed).Also,CBPT had no significant difference in any of the response inhibition scores compared to the control group, However,tDCS had a significant difference with the control group in the scores of action accuracy and action speed was.Conclusion:the CBPT method is not effective in improving active memory and inhibition of response,and tDCS method is only effective in improving response inhibition.children with ADHD disorders using tDCS can be more control their impulsivity.

Introduction: The relationship between body and mind is one of the issue about integration of different aspects of human being and it seems the neuro-psychological aspects are not separate from each other. The aim of the present study was to compare the explicit memory (recognition memory and recall memory) of bulimic women and normal women. Method: The study was a descriptive with ex-post facto design. Two sample groups, 20 bulimic women, from therapeutic clinics, who were seeking therapy for bulimia, and 20 normal women, were selected with targeted selection method. Bulimia Questionnaire (with adequate reliability and validity) and Explicit Memory (recall and recognition) Inventory were administered to the participants in each group. The data were analyzed using multivariate analysis of variance (MANOVA) method by using SPSS software. Findings: The results of study revealed that there was a significant difference in recognition memory (F=6/74, Sig=0/013) between two groups and therefore the bulimic group performed lower than the normal group. But there was no difference in recall memory (F=13, Sig=0/261) between the two groups. Conclusion: The findings indicated that Bulimic women have low performance in some aspects of memory than the normal women do.
