According to the World Health Organization, stroke is a series of sudden clinical symptoms. And it has no obvious cause other than vascular origin. Defective working memory is one of the most commonly occurring phenomena after brain damage. Attention and executive function (problem solving) are closely related to working memory. Cognitive Rehabilitation is a cognitive intervention program designed to rehabilitate cognitive deficiencies. The present study examined the effect of cognitive rehabilitation on spatial / verbal working memory, selective and divided attention, and problem solving in adults with stroke. 20 patients were equally divided into experimental and control groups. Cognitive rehabilitation computer program was performed 5 weeks and 5 days a week, and for 30-40 minutes. The research variables were measured by Wechsler's working memory test, N-back spatial working memory test, selective and divided attention program, Wisconsin sorting card test before and after the rehabilitation program. Significant improvement was observed in auditory and visual working memory and selective attention. This recovery may be due to changes in neural organization in response to injury. The cognitive rehabilitation program makes to re-learn mental acts and is based on brain flexibility that improves working memory and selective attention of patients. It seems that the lack of improvement observed in divided attention and problem solving is due to the lack of coordination and parallel processing in different regions of the brain due to infarct tissues.

The aim of this study was to investigate the effectiveness of the training of emotional competence in the improvement of anxiety, problem solving and working memory in children. It was a semi experimental research in which pre- test, post -test design with control group was used. Through the cluster sampling method 30 female children were selected from the primary schools of Babol city and then they were randomly put into two experimental and control groups. The assessment was performed using Multi-dimensional Children's Anxiety Scale (MASC), Social Solution Scheduler (SPSI-R) and Dunnian and Carpenter Working Memory Test (1980). The experimental group received an emotional competence training program based on two, EBP emotion-based prevention programs (Izard et al2004, 2008) and Cole's emotional knowledge intervention (2009), adapted from Hesarsorkhi (1395), for 10 group sessions for 60 minute. There was no intervention in the control group. The results of one-variable and multivariate covariance analysis showed that there is a significant difference between the experimental group and control group in the post-test in anxiety score constructive problem solving and memory working in the children. The results of this study showed that emotional competence training program can be an effective way to reduce anxiety and increase the ability of constructive problem solving, working memory of children.

The aim of this study was the comparison of cognitive processes (working memory and response inhibition) in methamphetamine-dependent individuals. The design of the present study is causal-comparative. The study population was all methamphetamine-dependent individuals and normal participants at Ilam. The sampling method of current research was available sampling. Participants consist of 30 methamphetamine-dependend and 30 normal participants. The color-word Stroop test (type PC) was performed for assessing response inhibition and for assessing working memory and evaluating subtest Wechsler memory span data(computer type) was used. The data were analyzed by multivariate analyses of variance. Results showed that theperformance of methamphetamine-dependent individuals in components digits span was significantly different from the normal group. Also, methamphetamine-dependent individuals in the performance of response inhibition was significantly different from normal, but the components of congruent reaction time and incongruent reaction time and components without incongruent response no significant difference was observed between the two groups. Results showed that the methamphetamine-dependence has significant influence on working memory and inhibitory responses.

In this study we examine the effect of relaxation training on anxiety reduction and on working memory capacity (WMC). In an experimental study the students of a secondary school in Tehran were selected using random cluster sampling. Through an anxiety test based on the Zung Self-Rating Anxiety Scale (1970), 40 girl students were divided into two test and control groups by random assignment. In the pre-test, students responded to questionnaire of working memory capacity (Daneman & Carpenter, 1980). The tests were organized in group form. In the next stage of research, the test group received 12 one-hour session training (3 sessions per week), and were offered relaxation techniques, as well as deep breathing and muscle relaxation, while no training was provided for the control group. Upon completion of the sessions in the post-test stage, both test and control groups were tested again with Zung Self-Rating Anxiety Scale and questionnaires of working memory capacity (Daneman & carpenter, 1980). The statistical methodology was based on multivariate analysis of covariance. The results of this study suggest that relaxation training increases the working memory capacity and its components, i.e. storage and processing, by way of decreasing anxiety. Therefore, relaxation training is a useful strategy for reduction of anxiety and promotion of working memory capacity
