Aim:The purpose of this study was to investigate the effects of one session of transcranial direct current stimulation (tDCS) on hand mental rotation (HMR) and visuo-spatial working memory (VSWM). Methods: The 54 right handed students of sport science at University of Tehran were selected and then were randomly divided into two groups of anodal (N=27) and sham (N=27), and further were divided in two subgroups according to site of stimulation (F4 & P4) (total of four groups). Before and after the application of tDCS, participants completed the HMR Task and Corsi test (to study VSWM). Findings: Results of anodal group showed a significant difference between the pre-test and post-test in reaction time and accuracy of HMR, also reaction time and span of Corsi in both sites (F4 & P4) . Also, comparing the effects between two sites in HMR, revealed that subjects responded faster and more accurately in F4 than P4. But only in foreward Corsi test, response time was faster in F4than P4. Conclusion: According to the findings of the present study, both F4 and P4 sites could be used to improve motor imagery and visual-spatial memory while the F4 showed better result.

Introduction: Given the protecting and aggravating role of cognitive emotion regulation strategies in Pathology, this study examined the mediating role of cognitive emotion regulation in the relationship between Brain-Behavioral Systems and impulsivity with craving in stimulant addiction. Method: In this study that was a descriptive and correlational design, 249 stimulants drug users who had been detoxified by purposeful sampling, and considering exclusion and inclusion criteria, were selected. Barratt Impulsiveness Scale, Behavioral Inhibition System (BIS) and Behavioral Activation System (BAS) Scales (Carver & White, 1994), short form of Persian version of cognitive emotion regulation questionnaire and desire for drug questionnaire were used to collect the data. Regression and path analysis were used to analyze the data. Findings: Sequential Regression analysis according to steps that had been suggested by Baron and Kenny (1986) reveald that maladaptive emotion regulation strategies can significantly have a mediating role between BAS and impulsivity with craving. Conclusion: Maladaptive emotion regulation strategies are one of the aggravating factors in craving related problems of stimulant drug users. This research suggests that intervention and relapse prevention programs must be designate considering the craving related emotion regulation strategies.

The aim of the research was to determine the difference in the effectiveness of cognitive therapy with positive psychotherapy on executive functions in patients with mild brain damage. Method: The present research method was a semi-experimental type with a pre-test and post-test design with a follow-up period. The statistical population of this research included all people with mild brain damage who referred to Shahada Haftam Tir and Baqity Elah Hospitals in Tehran in 2019. Among them, 30 people were purposefully selected and randomly assigned to three groups of cognitive rehabilitation treatment, positive psychotherapy and control group. The Wisconsin test was performed on each of the groups. The first experimental group received cognitive rehabilitation therapy and the second experimental group received positive psychotherapy. People in the control group did not receive any intervention. Analysis of variance with repeated measurements was used to analyze the data. The results showed that both interventions have an effect on increasing executive functions. But the effectiveness of cognitive rehabilitation treatment is more on executive functions(P05/0<). Therefore, it is recommended to neurologists and psychotherapists in order to reduce the complications of brain damage, in addition to medical treatments, cognitive rehabilitation treatment should be used as a complementary method

Aim: The purpose of this study was to investigate the effect of different internal and external focus of attention instructions on learning of over hand throw in educable mentally retarded students. Method: In this semi-experimental study, 12 boys and 6 girls from 12 to 14 years of age based on the IQ of 50 to 75 were randomly selected and according to the scores obtained in the pretest, were matched equally in the three groups including internal attention, near external attention and far external attention. Participants in the acquisition stage, in each group performed 4 blocks of 8 trials of throws with preferred hand. There was a 5 minutes resting between them. All three groups performed throws at a distance of 2 meters during the training stages. After the last training session, 10 throws were performed as a post-test and retention and transfer tests were performed 24 hours afterward, each of them included 10 throwing but transfer test was done for all three groups at a distance of 3 meters. Findings: Results showed that all three training groups had a progression from pre-test to transfer test and showed a significant difference (P≤0.05). Also the results showed far external attention group led to better learning, and then, the near external attention and internal attention groups, respectively performed better. Conclusion: In general, based on the research findings, the external attention group had a more stable learning and this confirms the constrained action hypothesis of Woolf et al (2001) in mentally retarded children.

Background: Nowadays, the study of neurological infrastructure of personality traits has a special place in neuropsychological research. According to Eysenck, the correlation between personality and behavior is the result of individual differences in the brain function. The purpose of the present study was to investigate the frontal EEG asymmetry according to neuroticism and extraversion dimensions.Methods: The statistical population of the present study was all male students of Payame Noor University of Tehran, who studied in the academic year of 1963-96. Based on the final scores of distribution in two dimensions of extroversion and neuroticism, four groups (extroverts, introverts, neuroticism and emotional stability) with 25 subjects were selected. The subjects completed the Eysenck Personality Questionnaire- Revised, Waterloo Handedness and footedness Questionnaires-Revised, and their eyedness was assessed, then the electrical activity of the brain of the subjects was recorded through EEG from different points on the scalp. Results: The findings of the study show that there is no significant difference between the four groups in the right frontopolar (FP2), right middle frontal (F4), right lateral frontal (F8) and right frontal cortex (RF) in alpha activity. There is a significant difference between the left frontopolar (FP1), left middle frontal (F3), left lateral frontal (F7) and left frontal cortex (LF) between the four groups (P<0.01); as alpha wave activity on left regions in neurotic and introverted individuals is more than emotional stable and extroverted subjects. Conclusion: In general, the findings of the present study strengthen the relationship between personality dimensions and frontal EEG asymmetry.

Introduction:Many studies have shown that borderline personality disorder is related to the neuropsychological deficits and there is also evidence that neurocognitive profile of patients with borderline personality disorder can be related to the consequences of this disorder. This study aimed to Examining the efficacy treatment of Computer-based Neurocognitive in people with borderline personality disorder. Method: this study's design was pre experimental with pretest- posttest. Studied population consisted of all patient with borderline personality disorder who were visited in clinics and health centers in Tehran. The sample included 30 patients who met the Diagnostic Interview for Borderline Personality Disorder—Revised version (DIB-R) criteria in the 4 scale affective dysregulation, impulse action patterns, cognitive– perceptual impairment and interpersonal relationship disturbance for borderline personality disorder. Patients were randomly assigned in experimental and control groups ( 15 patients in experimental group and 15 patient in control group), then therapeutic interventions were made. Subjects were also assessed by clinical, neuropsychological and functional measures in baseline and after 32 meet of the 16Weeks of computer-assisted cognitive remediation (experimental group) intervention or treatment as usual (control group) which were made twice a week. Findings: Covariance analysis results demonstrated that patients who received CACR showed greater improvement in working memory and psychosocial functioning results than patients treated with TAU, but symptom severity didn't have significant difference. Conclusion: Findings of this study showed the feasibility and potential the efficacy treatment of Computer-based Neurocognitive domains, suggesting a relatively limited clinical usefulness of the treatment of Computer-based Neurocognitive in the treatment of the borderline personality disorder.

Introduction: The purpose of this study was to compare three groups of women with MS comorbid with, and without depression, and normal women. Method: This study was a causal-comparative research design. Among women who have referred to the MS Society in Markazi Province, 24 women comorbid with depression were diagnosed through the Beck Depression Inventory and Structured Clinical Interview for Depression (SCID). Furthermore, they were screened after the consideration of inclusion criteria. In addition, a group of patients with multiple sclerosis without depression symptoms among screened women who did not show depression symptoms were selected. Finally, a group of normal women based on inclusion and exclusion criteria was chosen. Stroop test, Tower of London test and Digit span were used for data collection. Data were analyzed using multivariate statistical analysis (MANOVA). Findings: The study showed that women who suffered from MS and depression in the same time had a weaker performance in Stroop test, Tower of London test and Digit span rather than two other groups. Also, this study showed significant difference in terms of performance tests between women with multiple sclerosis without depression symptoms and normal group. Conclusion: The findings indicated that in addition to the difference in executive functions in MS patients compared to normal subjects, depression can intensify this difference. Due to this effect, paying attention to depression in the design of treatment is recommended.

Aim:Educational problems and especially the particular problems of learning in children have attracted much attention. One of the aspects to consider is the neuropsychological characteristics of these children.The aim of this study was to study the neuropsychological functions of the Wisconsin Card Sorting Test (cognitive flexibility, perseveration, time, first pattern efforts) in children with mathematical learning disabilities and compare them with normal children and children with other types of Learning disabilities. Method: For do this, using convenience, four groups of children (a group of normal students and three groups of students with mathematical, reading and writing learning disabilities), using purposeful sampling, were selected from children referred to the Children's Learning Center with special learning problems. The WCST test software was applied to the sample groups and the results were analyzed using MANOVA. Findings: The results showed that children with normal and mathematical disorder had a significant difference in cognitive flexibility, perseveration and effort for the first pattern. Also, children with special disabilities in mathematic had as much children with reading disabilities as dysfunction, but the two groups showed more dysfunction than children with a disability. Conclusion: Based on the results of this study, it can be concluded that the profile of the executive function of students with mathematical learning disability is different from the children with writing disability and normal children, but it similar with reading disabled children.

Introduction: As the number of people in autism spectrum disorder is increasing every day, the need for providing possibilities with regard to various teaching arenas including language learning is more being felt. The main aim of the present study was teaching English as a foreign language to children with high-functioning autism. Method: This qualitative case study investigated the effect of behavioral and cognitive coaching on teaching English to two verbal Persian-speaking language learners. The four skills of motor-imitation, echoic, tacting, and manding were used for teaching. Findings: The results showed that out of 103 language items, nine instances of failure were reported concerning both types of interventions. Sam who was taught based on behavioral intervention experienced nine instances failure (five instances in motor-imitation and four in echoic skill) and Mani none. Conclusion: Despite the slight differences, it seems that teaching based on cognitive intervention was more successful, and it can be recommended for teaching English to high-functioning autistic learners.

Introduction: Working memory deficit is one of the most common complaints in post-stroke patients. The present study aimed to investigate the efficacy of the con-commitment use of unihemispheric concurrent dual-site a-tDCS (a-tDCSUHCDS), computer-assisted cognitive rehabilitation and conventional (Single site) a-tDCS in comparison with computer-assisted cognitive rehabilitation without tDCS on the working memory in stroke patients. Method:32 participants (21 males and11 females; age range 40-65years) with subacute stroke were selected by purposeful sampling method & randomly assigned to three experimental conditions and a controlled group with sham stimulation. All groups completed sessions of the Dual N-back training task. A-tDCSUHCDS group received anodal tDCS over the left DLPFC and M1 and conventional (Single site) a-tDCS group received anodal tDCS over the left DLPFC. Result: A repeated measures analysis of variance revealed that the a-tDCSUHCDS group had the larger improvement in working memory tasks after the intervention. Also, at the 8-weeks follow-up, the a-tDCSUHCDS group still had larger improvements in mentioned tasks. Conclusion: These results indicated that there may be potential for the concomitant use of a-tDCSUHCDS and computer-assisted cognitive rehabilitation by increasing the excitability of the cortical network of brain regions that play an important role in executive functions, to enhance the efficiency of the cognitive rehabilitation programs of the stroke patients.

Methods: This was a pre-test and post-test quasi-experimental study with control group. Twenty male methamphetamine users were selected through purposive sampling and randomly assigned into two experimental and control groups (10 in each). The QEEG was recorded in all participants to evaluate absolute power of alpha wave in the frontal lobe region. A single session transcranial alternating current stimulation (tACS), for 20 min at 10 Hz or sham, was applied to the right dorsolateral prefrontal cortex (F4). At the end, QEEG was recorded again. Collected data were analyzed by multivariate covariance method. Findings: Findings showed that Experimental group showed greater absolute alpha power at F4, F3,F7 and Fz compared to the control group (p˂0.05).Discussion and Conclusion: According to the results, 10 Hz tACS stimulation over F4 can increase alpha activity at dorsolateral, ventrolateral and central prefrontal cortex, a region of the frontal lobes that is associated with cognitive functions. Regarding to cognitive role of alpha oscillations, it can be concluded that tACS stimulation at alpha Frequency (α-tACS) can be used as a non-pharmacological method to improve cognitive function in methamphetamine users.

Aim: The relation between cognition and emotion has always been interesting for researchers. Although they are separate domains, they interact with each other. The purpose of this study was to investigate the influence of shame and guilt emotions on phonological loop and visuSpatial Sketchpad of Working Memory. Method: A quasi-experimental pretest-posttest design was applied in this research. Sixty university students were selected through convenience sampling. Adult Wechsler test (digit span Test) and corsi blocks task were used for data collection. Results: The results of covariance analysis showed that shame and guilt emotions significantly affected phonological loop and visual-spatial working memory. Conclusion: Shame and Guilt Emotions can negative influence on working memory performance.

Introduction: This study aimed to evaluate and compare the effectiveness of music therapy and neurofeedback, as two non-invasive methods, on the reduction of pain in patients with somatic complaints. Method: The samples of the study include 86 students of Payame Noor University of Tehran who were selected on the basis of the complaints of physical pain and medical diagnosis. All participants completed measures of pain, physical symptoms, and Takata responded Sakata. Then they were divided into two intervention groups and received either music therapy or neurofeedback. The data were analyzed through running Covariance analysis. Findings: The results indicated that neurofeedback, compared to music therapy, had significant impact on reducing the patients' physical symptoms, especially on their headache. Conclusion: According to the results it could be argued that neurofeedback due to its effect on brain waves can be effective for adjusting and reducing psychosomatic pains.

Introduction: The aim of this study was to investigate the effectiveness of neurofeedback treatment on depression, anxiety, stress and psychosomatic abdominal pains in patients with clinical chronic psychosomatic abdominal pains in Shiraz. Methods: This research was a quasi-experimental study with pretest-posttest control group. The study population was all women with chronic psychosomatic abdominal pains among whom, 40 patients were selected for this study; ultimately, data were analyzed with 30 patients (experimental group=15 and control group=15). Participants were randomly assigned to 2 groups consisting of 15 participants who were divided into an experimental group and a control group. In this intervention, the experimental group was treated with neurofeedback for 10 weeks (3 times a week for 40 minutes) and the control group received no intervention and was put on a waiting list. Also, experimental and control groups completed the Depression Anxiety Stress Scales-21 (DASS-21) in pre-test and post-test. Multivariate analysis of covariance was used for data analysis. Findings: The results of covariance analysis showed that neurofeedback therapy had an impact on reducing anxiety and depression (P<0.001). In other words, 53% of depression variation and 57% of anxiety variation in patients were due to neurofeedback, but neurofeedback revealed no effect on stress. Conclusion: It was concluded that neurofeedback could significantly reduce depression and anxiety, but it had no effect on stress.
