Abstract
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.

Abstract
The aim of this study was to examine the effect of aerobic and strength exercises and interactive time circadian rhythms of everyday memory performance, retrospective and prospective youth. Methods quasi-experimental, pretest - posttest randomized groups. 48 participants were randomly divided into four groups: aerobic training STR X in the morning (n =12), strength training fitness in the morning (n =12), exercise STR X age (n =12), and strength training fitness in age (n =12), the exercise period of 2 months (8 weeks, 3 times a week, and every 45 minutes) respectively. Participants Pittsburgh Sleep Quality Index (PSQI), a questionnaire circadian cycles Steve Horn questionnaire prospective and retrospective memory and RAM questionnaires were completed daily.Inferential statistics such as ANOVA test of the indicators in the pre-test and post-test in two-way ANOVA and Bonferroni post hoc test was used to analyze the data. Results showed that participants in training t-RX power in the morning and in the evening a higher average daily memory. And participants in training t-RX and power in both the morning and evening with retrospective memory were weaker. Average memory function prospective and retrospective exercises T oryx and fitness in the morning and evening statistically significant difference, and people in the morning activities with prospective memory and retrospective better than those in the era of work , have. The average daily memory exercises and fitness in the morning and evening t oryx statistically significant, and people who are active in the afternoon with daily memory better. Physical activity and aerobic training and strength is increasing everyday memory. (P < 0.05)In the meantime, do cardio in the morning and in the evening can improve the power performance is better.

Abstract
The aim of the present study was to investigate prospective and retrospective memory and cognitive ability in three groups of personality based on reinforcement sensitivity theory. For this purpose, first, 358 students Bu Ali Sina university were selected through a multistage cluster sampling. Then Brain / behavioral Systems questionnaire were distributed among them to be answered. After initial data analysis, 51 of them, based on cluster analysis in Brain / behavioral Systems questionnaire were selected, in order to test the hypothesis of this study, participants were studied in dimensions of prospective and retrospective memory and cognitive ability. The collected data were analyzed using descriptive indicators, multivariate analysis of variance and post hoc tests. Results showed significant difference between three personality groups in memory and cognitive ability. So that, group with high behavioral inhibition system sensitivity have better performance in components of retrospective memory, prospective memory, general memory and ability of naming; group with high sensitivity of fight-flight-freeze system have higher scores in prospective memory and general memory. The results showed that more active and less active of brain/ behavioral systems may be in close relation with memory and other cognitive abilities. It seems that cognitive abilities can to be influenced by the brain systems associated with reinforcement sensitivity and thereby cognitive functions changed.

Abstract
The purpose of this study was to examine psychometric characteristics of memory scale: measure of everbody functions of memory in students. The research design is a correlation type. The population of this study is all students of elementary schools in Semnan city. 220 students were selected by cluster random sampling method and their parents responded to the memory scale (Geurtin et al., 2018). SPSS-22 and Lisrel 8.54 were used for data analysis, Cronbach's alpha coefficient, multivariate analysis of variance and rock curves. In the context of construct validity there was a significant difference between the two groups; normal students and students with learning disabilities in all components of memory; effortful/intentional learning, automatic/procedural learning, working memory and prospective memory/organization. In the context of the discriminant validity, the levels below the rock curve for each component showed the ability to differentiate between normal students and students with learning disabilities. The memory scale has an internal consistency and a good stability coefficient. The results of the factor analysis showed that this scale was made up of four factors of effortful/intentional learning, automatic/procedural learning, working memory and prospective memory/organization. Cronbach's alpha for effortful/intentional learning was 0.86, prospective memory/organization of 0.77, working memory 0.70, and , automatic/procedural learning 0.82 and for the whole scale 0.93. Findings of the research indicate that the Persian version of the memory questionnaire in the students’ community has acceptable psychometric properties.
