Multiple sclerosis (MS) is a demyelinating disease of the CNS that due to cognitive impairment, can reduce the quality of life in these patients. The aim of this study is to evaluate effect of computerized cognitive rehabilitation on prospective & working memory function in Multiple Sclerosis patients. 46 MS patients aged 20–40 who have the inclusion criteria, were randomly assigned to experimental and waiting-list control groups. Experimental group trained for 12 session with a Memory rehabilitation software and waiting-list control group did not receive any intervention and training of this group was postponed after conducting research. Daneman and Carpenter's capacity working memory and Retrospective-Prospective Memory Scale was applied at pretest, posttest, and follow-up. The results of repeated measures ANOVA showed a significant difference between the means of working memory in experimental and waiting-list control groups. Also, the results of the present study indicate that a significant difference between the means of prospective memory in experimental and waiting-list control groups. Moreover, the post-test and follow-up scores in the experimental group was not statistically different. So Computerized cognitive rehabilitation have significant effect on prospective and working memory performance in patients with Multiple sclerosis and it can be used as an effective and helpful method to improve memory performance of these patients.

In this study was investigated the effect of explanation levels (self - explanation, instructional explanation, no explanation) according to learner prior - knowledge (learner with high and low knowledge) in a computer - based multimedia learning environm ent. Participants were 120 students of gifted and ordinary high school that randomly were divided into four experimental groups. Learning about calculate the area of complex geometric shapes were presented to students through worked - out example. Were used indicators cognitive load and transfer function in interpretation the impact of these activities on learners. Data were analyzed through two - way ANOVA. Results showed the effect of explanation levels on cognitive load during training is dependent to prior - knowledge. Lower - knowledge learners in transfer tests had the best learning outcome and suffered less cognitive load through receive instructional explanation. While higher - knowledge learners in near transfer had the best learning outcome and suffered less cognitive load through self - explanation but this hypothesis was not confirmed in far transfer .Students who received instructional explanation had the best learning outcome in tests and suffered less cognitive load.

This study to do identifying processes and strategies of emotion regulation and designing developmental model based on self-regulation patterns. Thus, this study examined emotion regulation with a developmental perspective in children age 4 - 12 years In Tehran. To 108 children, scenarios including four emotions namely sadness, madness, worry and pain were read. After the stories were read to the subjects and duly understood by them, and once an emotional atmosphere was created, subjects had an emotion regulation interview (ERI) and observation. Findings show that emotion regulation developed from extra-organismic self-regulation (input and output) toward intra-organismic (central processing). This trajectory is situation, attention and perception change, responding and expression modulating and internal-cognitive regulation.

working memory is the comprehensive cognitive system that embedded attentional and memorical mechanisms and therefore can be used in systematic research of cognitive problems. The aim of this study was to investigate the predictive role of working memory capacity and executive functions (shifting, inhibition and updating) for Obsessive Compulsive Disorder. We selected 164 student (90 male and 74 female) from university of Tehran with random sampling method and they completed Maudsley Obsessional – Compulsive Inventory (Hodgson & Rachman, 1977), the Digit Backward Span Task (workingmemory capacity), Forward Span task (Short Term Memory), Stroop (inhibition, Spreen & Strauss, 1998), Set- Switching Task (shifting, Rogers & Monsell, 1995) and Keep Track Task (updating, Martinez, et al., 2011). Data analyzing used regression showed working memory and executive function totally predict considerable amount (67 percent) of obsessive compulsive predisposition. Therefore it can be concluding, obsessive people have crucial weakness in storage, monitoring and executive cognitive function (in general attention control) and we can use training in these functions as treatment strategies.

Low self-esteem is one of the key factors underlying psychopathology, such as test anxiety. It seems that the activation of positive self-representations in memory plays an important role in self-perception. The aim of this article was to determine the effect of strengthening memory representations on self-esteem in people with test anxiety. This study was based on a quasi-experimental design with pretest and post-test. According to retrieval competition approach, a training package was designed to promote self-esteem and after verifying its content validity by 5 expert psychologist, the intervention was administered in 10 sessions (a one-hour session per week). Participants were 10 high school students with test anxiety diagnosis which were selected by purposive and available sampling; and completed Spielberger Test Anxiety Inventory (TAI) and Rosenberg Self-Esteem Scale (RSES) before and after the intervention and also one month follow up. Data analysis was performed using one-way trend analysis (one-way ANOVA with repeated measures). The results indicated that this intervention could lead to improve self-esteem and decrease test anxiety in participants (p˂0.01) and this trend continued until one month follow-up. As a result, it seems that interventions on the factors underlying psychopathology, such as low self-esteem, can have beneficial as well as proactive effects in this area and We may be able to make changes in self-concept even with no deliberate challenge to the thoughts.

This research aimed to investigate the effect of metacognitive awareness on decision-making styles and emotion regulation in female high school students during 2016 in Tabriz, Iran. We conducted a pre- and post-test quasi-experimental research design with a control group. Two classes were selected by cluster sampling method and randomly assigned to experimental (n=19) and control (n=19) groups. A metacognitive awareness intervention program was performed in eight sessions (once a week in 90-minutes) for the experimental group but the control group did not receive any intervention and served as the benchmarking point of the comparison. The Decision Styles Questionnaire (Leykin & DeRubeis, 2010) and Regulation of Emotion Questionnaire (Phillips & Power, 2007) were administered. Data were analyzed by multivariate analysis of covariance (MANCOVA). The result showed a significant decrease in the score of the avoidant, anxious, intuitive, and spontaneous dimensions as well as a significant increase in the score of the dependent dimension of decision-making styles in the experimental group compared with the control group. Moreover, the scores of the dysfunction dimension of emotion regulation decreased significantly in the experimental group, while, the scores of the function dimension increased significantly.

The failures of memory function in post-traumatic stress disorder and its relationship with severity of symptoms need to take new approaches to improve the memory performance in patients. The aim of this study was to investigate the Effectiveness of emotional working memory Training on improvement memory in adolescents with Post- Traumatic Stress Disorder (PTSD). For this purpose, 4 adolescents (M: 2 F: 2) were selected available sampling by using 2 instruments (SCID-I) & (IES-R) The selected people– one by one were under emotional working memory training during 20 sessions. All people were assessed during three stages (pre-training, post- training and 2 month follow up) by children' Wechsler Digit Span Test (direct and reverse). Data were analyzed using the indices for trend changes, slope and the visual inspection of the charts; recovery percent index and effect size were used to determine the clinical significance. The results showed that emotional working memory training lead to increase in ability of participants in memory from pretest to follow up who suffering from Post- Traumatic Stress Disorders. Regarding the current study, it can be said that emotional working memory training is an appropriate choice for increase in memory in adolescents suffering from Post- Traumatic Stress Disorder
