Aim: The present study was a quasi-experimental study with pretest-posttest design with a control group aimed to investigate the effect of computerized cognitive rehabilitation while stimulating anodic prefrontal cortex on executive and working memory functions in adolescents with diabetes type 1. Method: 20 adolescents aged 15-18 years with diabetes were selected from the Diabetes Association of Bonab city and were randomly divided into two experimental and control groups(n = 10). The executive functions and working memory of both experimental and control groups were assessed in the pre-test and post-test stages through the Wisconsin Card Sorting Test software, and memory and attention improvement software. For intervention, the experimental group received cognitive rehabilitation for working memory in 10 half-hour sessions(one day in between), simultaneously stimulating Fp1 and Fp2 with memory and attention improvement software. Findings: The results of data analysis using covariance analysis showed improvement in cognitive flexibility and working memory and a decrease in overall perseveration in the experimental group. Conclusion: According to the results of this study, cognitive working memory rehabilitation can be used simultaneously with anodic stimulation of the prefrontal cortex as an effective method for improving executive functions and working memory in type 1 diabetic patients.

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: The relationship between body and mind is one of the issue about integration of different aspects of human being and it seems the neuro-psychological aspects are not separate from each other. The aim of the present study was to compare the explicit memory (recognition memory and recall memory) of bulimic women and normal women. Method: The study was a descriptive with ex-post facto design. Two sample groups, 20 bulimic women, from therapeutic clinics, who were seeking therapy for bulimia, and 20 normal women, were selected with targeted selection method. Bulimia Questionnaire (with adequate reliability and validity) and Explicit Memory (recall and recognition) Inventory were administered to the participants in each group. The data were analyzed using multivariate analysis of variance (MANOVA) method by using SPSS software. Findings: The results of study revealed that there was a significant difference in recognition memory (F=6/74, Sig=0/013) between two groups and therefore the bulimic group performed lower than the normal group. But there was no difference in recall memory (F=13, Sig=0/261) between the two groups. Conclusion: The findings indicated that Bulimic women have low performance in some aspects of memory than the normal women do.
