Aim of this research was exploring effect of transcranial direct current stimulation (TDCS) on working memory (WM) in dorsolateral prefrontal cortex (DLPFC) region in healthy people.The method used in this research was experimental with random assignment and control group. The population was male students of Kharazmi university in range of 18 to 23 years old. Thirty participant undertook three experimental sessions in which they received 15 minutes of  2 mA anodal TDCS or sham TDCS. After and before stimulation participant performed n-back task to measure reaction time and correct answers. After analysis of covariance there was significant  statistically changing in reaction time and correct answers.The results shows that anodal stimulation reduced reaction time and increased correct answers and it seems made enhance on working memory

The purpose of the present study was to compare effects of self-focused attention on memory bias in individuals with social anxiety. To do this, 45 male students in Tabriz University were selected to participate in the study who had higher scores in Connor social phobia inventory (SPIN) than its cut point. The sampling method was available. Participants were randomly divided into three groups: two experimental groups and one control group. All the subjects were presented the emotionally words to recall. During the experiment, one group received the false feedback of increased self-focused attention, and the other group received the false feedback of decreased self-focused attention. The control group received non-relevant feedback. Next, previous emotional words were presented with a series of other words for subjects to recognize. Using signal detection theory, response bias (ß) and response sensitivity (d'), were calculated for the recognition of emotional words. The data was analyzed by MANOVA. The results showed that there is significant difference in response sensitivity among three groups, but no significant difference in response bias was seen among the groups. Based on the findings, sensitivity of people with social anxiety in dealing with stressful situations and negative social and also individual memory bias were confirmed.  

The aim of present study was detecting the difference between conscience, positive and negative affection at different levels of moral judgment, and exploring the concurrent effect of conscience and affections (positive and negative) at different levels of moral judgment. In this comparative study, 160 male and female undergraduate students of Kharazmi University in 1391-92 academic year completed the Moral Development Test "Ma", Gordon's Five-Factor Questionnaire and Positive and Negative Experience Scale. Discriminant analysis was used for data analysis. Results showed that conscience cannot distinguish different levels of moral judgment from each other and they are first negative and then positive affection which can distinguish one level of moral judgment from the others. Negative affection has greatest role at the concurrent relation of conscience and affections (positive and negative) in predicting the levels of moral judgment, and conscience and positive affections lose their diagnosis power. The above findings will be discussed based on trait perspectives, Kohlberg's theory about the characteristics of each of the levels and the role of affections in predict the behavior of judgment.

The proposed link between brain laterality and individual differences in cognitive tasks provided the theoretical foundation for the present study. The main purpose of this study was to investigate this potential link, specifically between one aspect of brain function, namely hand dominance, and one type of cognitive task, namely the ability to perceive short intervals of time. The sample included 40 girls and 40 boys left hands and 40 girls and 40 boys right hands in school students fasa city  that were selected  with the help of the Edinburgh Handedness Inventory and also time Perception  measured  with  four methods of production, reproduction, verbal estimation and comparison by standard software .Regression analysis showed that age predicted negatively and significantly time perception to the measuring verbal estimation and production method. Handedness was positively and significantly predicted measuring verbal estimation method time perception. Logistic regression results also showed that Handedness predicted the time perception the measuring comparison method. In this study  , not showed significantly different between the sexes. Summarizes the results show that right-handed people than left-handers to perceive higher intervals of time but at the time discrepancies are close to each other have more wrong.  

Introduction: Emotion regulation problems can cause important disorders in children and adolescents. Since emotion dysregulation has major role in internalizing and externalizing problems of children and adolescents, adolescence is  an important opportunity for changes in emotional experiences, emotional regulation and also increasing mental disorders and generalized changes in social relationships. The aim of this research is to study the effectiveness of training emotion regulation skills in improvement of executive function and emotion regulation strategies of at risk adolescents. Method: The method of this research is experimental that we used pre- test and post -test with control group.24 teenage girls have been selected from hazardous areas of Tehran with accessible manner and randomly they have been appointed in experimental and control group.The members of experimental group got education program of emotion regulation skills in the base  of dialectical behavioral therapy that was derived from Linehan model  in 8 group sessions,while the control group don’t take any intervention.Results: Training emotion regulation skills increased the scores of adaptive strategies and decreased the scores of maladaptive strategies. Also there was an increase in total number correct of executive function variable and number of categories completed rather than control group.Conclusion: Training of emotion regulation skills can affect in modifying and moderating of emotional reactions in adolescents and also it can affects on involved cognitive processes.

This study examined the mediating effect of positive and negative achievement emotions on the relationship between causal attributions and academic self-regulation among university students. On a sample consisting of 270 students (93 male 177 female) were administrated the achievement emotion questionnaire (Pekrun, Goetz & Perry, 2005).), attributin style questionnaire (Peterson, Semel, Beayer, Abramson, Metalsky & Seligman, 1982) and academic self-regulation scale (Ryan & Connell, 1989). Structural equation modeling was used to assess the mediating effects model of achievement emotions on the relationship between causal attributions and academic self-regulation. results showed that there is a positive significant correlation between adaptive attribution style with positive achievement emotions and a positive significant correlation between nonadaptive attribution style with negative achievement emotions and positive significant correlation between positive achievement emotions with self-regulation and negative correlation between negative emotions and academic self-regulation. Results also indicated that the relationship between adaptive and non-adaptive attribution styles and academic self-regulation by positive and negative achievement emotions is mediated. All of the regression weights in the both models were statistically significant and in the the mediating model of positive and negative achievement emotions, models' predictors accounted for 25% and 21% of the variance in academic self-regulation, respectively. In sum, the results emphysising on the mediating role of achievement emotions, provide further support for the attribution theory. 

This study aimed to assess cognitive fatigue in M.S disease and non-disease based on attributional style. First, 40 patients were selected among Women members of the MS Society of Esfahan City according to scores obtained in attribution style questionnair. Then a control group of 40 women without M.S who were matched to disease in scores of attribution style and the characteristics of age, education and marital status were selected. Subjects in 8 groups (4 control, 4 experiment) 10 patients each were assigned. This has some stage. First, subjects in the control and experiment group were facing with controllable and uncontrollable problems followed up in the second, the groups solved Anagram problems. Data were analyzed by the analysis of variance and Tukey test. The results indicated the groups are differences in cognitive fatigue according to the attributional style and type of tasks. Patients has a positive attribution style were faced with unsolvable tasks showing less cognitive fatigue compared patients with negative attributional style. Also there was no difference between these with normal counterparts. M.S with negative attribution style in face with unsolvable tasks showed more cognitive fatigue compared patients with positive attributional style and solvable task.    

The aim of the present study is the predict of worry based on behavioral activation and inhibition systems, cognitive emotion regulation strategies and intolerance of uncertainty in students. In terms of objective, this study is off is study is the fundamental type, and in terms of data collection, it is of the correlation type. For this purpose, 200 students were selected using convenience sampling (available sampling) from Masters students at the Islamic Azad University of Tabriz in 2014-2015 school year. The participants were asked to answer the measures of behavioral activation and inhibition systems (BAS/BIS), Cognitive Emotion Regulation Questionnaire (SERQ), intolerance of uncertainty Scale (IUS) and the Penn state worry Questionnaire (PSWQ). Data were analyzed by the analysis of variance and stepwise regression. Results showed that there was a significant positive correlation between the variables of behavioral inhibition system, negative cognitive emotion regulation strategies, and intolerance of uncertainty in one hand, and worry in another hand (p<0.01), and there was a negative significant relationship between the positive strategies of cognitive emotion regulation and worry (p<0.01). These variables were able to predict 1/54 of the total variance of concern (p<0.001). In addition, the relationship between the behavioral activator system variable and worry was not significant. Worry is related to a variety of negative consequences, including a high degree of emotional reactivity and inefficient regulation styles. Thus, the findings of this study have practical implications in the clinical arena.

All the people sometimes in their life become anxious in social situations. Social phobia is exaggerated form of these fears. Social phobic patients are afraid of being seen. They scared of act somehow that being contemptional or shameful.Researchers have found four type of cognitive bias in anxious individuals: attention bias, memory bias, judgment (reasoning) and interpretation bias.One kind of reasoning bias is jumping to conclusion, that represent judgment or making decision about something without having all truth or conclusion without rationalization. So, it's possible that social phobic patients do this bias in fearful social situations.Design of this research is casual-comparative style. And for sampling, we use of convenience sampling and two groups have been experimented: 45 individuals with social phobia disorder and 45 non-patients individauls.Findings have shown that patients with social phobia, in anxiety induction situation, have jumping to conclusion bias in compare to non-patients group and make hastier decisions and judgments. Indeed, for being free from anxiety, they make decision with little and imperfect evidences. Also, result has shown that presence of supervisor could be a stressor factor for individual with social phobia that would have a negative effect on their reasoning in conditions of decision making and judgment.    

People with obsessive compulsive behaviors typically occur suffer. The present study compared cognitive functioning and theory of mind in people with symptoms of obsessive - compulsive disorder and their normal people. The study sample was male students in Tabriz University in the academic year 2013-14. The sample consisted of 35 individuals with symptoms of obsessive - compulsive disorder and 35 normal subjects. Tools used in this study were the Wisconsin Test, Wechsler Memory Test, Theory of Mind Inventory, Compulsive Inventory, Beck Depression Inventory and a structured clinical interview. Data were analyzed using multivariate analysis. Between two groups of variables Drjamandgy error, total error, orientation, mental control, digit span, visual memory, learning Tdayha and theory of mind, there was significant difference. However, Personal Information and Public variables and logical memory, there was no significant difference between groups. The results showed that people with symptoms of obsessive - compulsive disorder without symptoms of depression, there are shortcomings in cognitive functioning and theory of mind.

The aim of this research was effect of immediate, recent and remote explicit motor memory on reconsolidation process based stabilization and enhancement and retrograde interference. The statistical sample were 72 right-handed young girl. subjects were divided into two groups of  immediate explicit motor  memory (immediate recall, immediate recall + immediate interference), two groups of  recent explicit motor memory(recall after 5h, recall after 5h + Interference delayed after 5h) and two groups of  remote explicit motor  memory (recall after 24h, recall after 24h + Interference delayed after 24h). This research was consisted of two phases of acquisition and retention and alternating serial reaction time and two selection reaction time tasks were used. In the first phase check out reconsolidation based enhancement and in the second phase check out reconsolidation based stabilization and retrograde interference. In the first phase, results showed that for recall groups after 24h and 5h occurred reconsolidation based enhancement. In the second phase, results showed that for  recent (recall after 5h, recall after 5h + Interference delayed after 5h) and remote (recall after 24h, recall after 24h + Interference delayed after 24h) memory groups occurred reconsolidation based stabilization. In group with immediate offline period (immediate recall+ immediate interference) occurred retrograde interference effect.

Purpose of this research was the effect of meta-cognitive treatment in group method onthought control strategies in addict man under methadone treatment. Among patients treated with methadone during methadone treatment center in Tarighat no of Tehran city on date Bahman to Ordibehesht 1393 ,30 persons were recruited and randomly assigned to two groups an experiment (n = 15) and group controls (n = 15) were assigned. The participants fill the questionnaires for thought control strategies Wells and Davies before training in method of meta-cognitive and after it. To examin the effect of Metacognitive training method, pre-test was subtracted from pos-testand the means of two experimental and control groups were compared using t-test.  The results showed that there was significant differences in thought control strategies between two groups and he mean of the experimental group was lower According to the results about the difference between the control and experimental groups  in receiving cognitive training intervention on  the Addicts' mind control, it seems, this teaching can be effective in meta-cognitive of the addicts and as a result modify their thought control strategies.

This study examined the moderating effect of cultural and sex differences on the relationship between appraisal processes with academic stress among male and female Iranian and Swedish university students. On a sample consisting of 212 students [112 Iranian (male 32 and female 78) 100 Swedish (male 29 and female 71)] were administrated the primary and secondary appraisal processes and Academic Stress Questionnaire. The results of multiple regression model showed significant positive relationship between primary appraisal and academic stress among Iranian students and nonsignificant positive relationship between primary appraisal and academic stress among Swedish students. Results also indicated that there was a significant negative correlation between secondary appraisal and academic stress among Iranian and Swedish students. Results also showed that there was a nonsignificant positive relationship between primary appraisal and academic stress and a significant negative relationship between secondary appraisal and academic stress among both sexes. Therefore, the relationship between primary and secondary appraisals and academic stress by sex was not moderated. In sum, these findings emphasize that for the purpose of prediction of academic stress the functional properties of primary appraisal were dissimilar and the functional properties of secondary appraisal were similar in two cultural contexts and the functional properties primary and secondary appraisals were similar in tow sex groups.

The aim of this research was to investigate visual-spatial component of working memory and short-term memory in students with learning disorders and comparison with normal students.
30 3rd grade elementary students with learning disorders and 10 3rd grade elementary normal students were selected through multistage random cluster sampling. The instruments were Scale for Identifying Students with Spelling Learning Disability, Keymath Test, Reading Level Diagnostic Test, Wechsler Intelligence Scale for Children (WISC), Clinical Interview and Corsi Blocks Task for assessing visual-spatial component of working memory and short-term memory. Data were analyzed by ANOVA. The results showed that there is a significant difference between students with reading, mathematics and spelling learning disorders and normal students in visual-spatial component of working memory and short-term memory. Students with mathematics disorder had lower performance in these components.  Students with learning disorders particularlymathematics disorder had deficits in visual-spatial component of working memory and short-term memory. This problem should be assessed in order to plan appropriate interventions.
 

The aim of the present study was to investigate the amount of performance in working memory, and also comparing the dimensions of behavioral activation system (BAS) and behavioral inhibition system (BIS) in different levels of stress. For this purpose, first, 560 persons of high school adolescent students (including boys and girls) of Hamadan's schools were selected through a multistage cluster sampling. After the initial data analysis, 87 of them, based on final score distribution (Z Standard) were chosen. Finally, in order to test the hypothesis of this study, participants were have studied to measure working memory and behavioral inhibition and behavioral activation systems. The collected data were analyzed using a Multivariate analysis of variance, ANOVA and post hoc tests. Results showed that there is no significant interaction between gender and stress variables considering the working memory and behavioral inhibition and activation system. On the other hand, results showed that high stress levels can lead to a decline in working memory function and participants with high levels of stress were also at higher level in terms of activity of behavioral activation system (BAS) and behavioral inhibition system (BIS).

Since working memory capacity (WMC) predicts individual differences in the wide range of abilities, this experiment tested the effect of WMC on time perception in preschool children.
At first, 108 children’s working memory capacity were measured by CANTAB tests and then 21 children with high working memory capacity and 20 children with low working memory capacity were assigned. Then, both groups performed two reproduction tasks they instructed to reproduce 700 and 3000 millisecond intervals in mono task, and to reproduce 3000 ms with a performing concurrent non-temporal task as a dual task. Data analyzed by mixed design ANOVA and post hoc tests. Results showed that in mono task, accuracy of high WMC was better than the low WMC group. In dual task, although there was no significant difference in the accuracy of reproduction task, children with high WMC had better performance in non-temporal task. Furthermore, children with low WMC were more variable performance than high WMC in all intervals.
 

The purpose of this study was to examine the effect of different recall distance‌s on explicit motor memory consolidation. Thirty Six students were randomly divided into three groups with distance of immediate, 6, and 24 hours in recall test. This research consisted of two phases of acquisition and recall. In acquisition period, all groups practiced the task for 15 blocks of 80 trials (five epochs of 400 trails). Then in recall phase, all experimental groups were practiced five blocks of  80 trials (one epoch of 400 trails). Also, all groups practiced the alternating serial reaction time task in each epoch. Data were analyzed with using the ANOVA repeated measure. Results showed that in acquisition phase the group main effect and interaction effect between group and epoch were not significant. But epoch main effect was significant and practice lead to inducing sequence reaction time in third epoch related to other epochs. In recall phase, the epoch main effect and interactive effect between group and epoch were significant, but group main effect was not significant. Results in Duncan Post Hoc showed that only group with 24h off line periods, in recall test, had the better performance than acquisition phase.  Practice in group with 24h offline lead to decrease the reaction time than other group .Our Results indicated that 24h offline period for recall test is better time for optimal performance.
