Introduction: The present study aimed at investigating the effect of emotional experience induction on the executive functi of attention and working memory with regard to depressive continumm. Method: In the first stage 449 students of Kharazmi university of Tehran were randomly screened by means of second version of the beck depression inventory (BDI-II (and then 34 of them who had obtained equal or up to +1/5 and equal or lower than -1/5 standard z score were selected as the sample group and were invited to next stage of the research. Then, they were examined individually in three steps. The first stage was related to the basic activity of the executive functions of the attention and working memory before watching emotional movies and the next two stages of the experiment were conducted after watching the selected emotional movies including positive and negative emotional movies. Findings: The finding indicated that emotional experience induction can affect attention without the main effect of group. Besided, results related to the working memory showed that the performance of the two groups in different emotional situations has significant difference. Conclusion: Regarding the results of the present study, attention maybe affected under more severe concitions of depression and working memory performance, as an executive function, maybe impaired under the influence of depression. This makes it difficult to select and process information quickly for performing the task.

Introduction: Emotional eavesdropping is information that observer receives by listening and watching emotional reactions directed by third party (as coach) to another (model). It seems mirror neurons system is one mechanism responsible for this but ways in which emotional eavesdropping discharges this neurons are not clear. So the aim of this study was to investigate the effect of emotional eavesdropping of model on mirror neurons activity (mu rhythm suppression). Methods: For this reason, 22 right hand novice athletes (average age 20/69±1/10) participate voluntary in this research. These participants observed three instructional video of free throw in basketball that also display emotional reactions (positive, neutral, negative) of coach and model about model performance. Four Brain waves records were done by electroencephalographic assessments: one base record with open eyes as index of mirror neurons activity in rest and three records during positive, neutral and negative emotional eavesdropping in three regions C3, C4 and Cz. Findings: 3×3 within subjects ANOVA findings demonstrated that mu rhythm suppressed during three emotional eavesdropping in three central regions. Post hoc results showed more significant mu rhythm suppression during negative emotional eavesdropping in C4 than other conditions. Conclusion: thus, these findings confirm valance hypothesis about negative emotion and right hemisphere hypothesis and it seems emotional eavesdropping modulate mirror neurons activity.

This effect has been observed in various cognitive tasks and several models have been proposed to account it. The aim of present study is investigating concreteness and emotionality effects on semantic processing in the Persian language using Event-related potentials. Method: A quasi-experimental design, repeated measures is employed to examine concreteness as well as emotionality effects on visual word processing. 24 male students were taken by convenience sampling and set in the experimental condition that included a lexical decision task. The activation of neural networks was recorded while participants responded to concrete, abstract and emotional words. Findings: Comparison of related-potentials showed that emotional words elicited an early and more pronounced P300 than both concrete and abstract words. Nonetheless, concrete and abstract words evoked late and larger N400 and P600 In the second and third time windows respectively. Conclusion: The pattern of results suggest that concreteness effect in Persian is not entirely consistent with existing theories provided in this paper, so there may be an increased chance for other explanations to clarify the concreteness and emotionality effect on visual word processing in the Persian language.

Abstract: Introduction: Adults with attention-deficit/hyperactivity disorder (ADHD) have some impairment in emotional relationship which can be due to problems in emotional processing. The present study uses the event-dependent potential (ERP) method to investigate the neural correlations of the early stages of emotional face processing in the N170 component when observing faces with different emotions in adults with ADHD compared to adults without ADHD.Methods: A total of 12 adults between 20 and 42 years old (6 males and 6 females) with ADHD were compared with 12 adults without ADHD (6 males and 6 females). Participants identified faces with different emotions while their brain activity was recorded using the event-dependent potential method.Results: The results showed that the N170 component for a neutral face was significantly different both for women with ADHD in the P8 region and men with ADHD in the O1 region comparing to adults without the disorder. (P <0.05)Conclusion: The present study supports the notion that people with ADHD in the early stages of facial processing and facial expressions are different from people without the disorder, which can affect the interpretation of facial expressions and emotions.

Objective: The present study was conducted with the aim of Comparing the effectiveness of transcranial direct current stimulation and repeated Transcranial Magnetic Stimulation treatment on working memory, impulsivity and self-harm behaviors in people with borderline personality. Method: The current research is semi-experimental with pre-test-post-test and control groups. The statistical population of this research includes the clients of some counseling centers in Ardabil city in 1401. The sample of this study consisted of 45 people with borderline personality disorder who were selected by the available sampling method. This study included 3 groups and each group included 15 people. Each subject was randomly assigned to two treatment groups (tDCS and rTMS) and a control group. The tools of this research included N-back working memory test, Barratt Impulsivity questionnaire, self-harm questionnaire, tDCS and rTMS.Findings: The results showed that the treatment of tDCS and rTMS has a significant effect on impulsivity, working memory and self-harm in borderline personality disorder patients. And the results show that after controlling the effect of the pre-test on the post-test to compare scores, working memory, impulsivity and self-harm among the three groups, there is a significant difference at the error level (0.05). The results of Bonferroni's post hoc test also showed that between the effectiveness of the two treatment methods, rTMS treatment was more effective than tDCS. Conclusion: The results showed that tDCS and rTMS led to the improvement of working memory in people with borderline personality disorder and also reduced the level of impulsivity and self-harm behaviors.
