Aim: The aim of this study was to determine the effect of women's sexual cycles on executive functions and emotional recognition. Method: The present study is a descriptive causal-comparative study that studied a group of women in three sexual stages (bleeding, follicular, and luteal). The research sample consisted of 30 healthy female volunteers aged 20 to 40 years from the city of Isfahan who were selected from Isfahan by available means and according to the inclusion criteria. Data collection tools included Wisconsin Card Classification Test software, Stroop Test software, NBK test software, and Montania et al. (2007) Emotion Recognition Scale. Results: According to the results of repeated measures analysis of variance, there was no difference in executive functions and recognition of facial emotion in different sexual cycles in healthy Iranian women aged 20 to 40 years. Conclusion: Given that recent findings with brain imaging technologies have shown that hormone levels in the brain affect both brain structure and function, further studies with more accurate tools to determine the effects of hormones on cognitive and executive functions And face processing is necessary. Because, these differences seem to be so subtle that tools such as the tests used in this study, could not detect it.

Introduction: Executive functions are excellent cognitive functions that guide other cognitive activities of the brain. Executable functions help the individual to perform his learning tasks and intelligence operations. The purpose of this study was to investigate the effectiveness of cognitive rehabilitation of executive functions on improving the academic performance of probative students. Method: The present study was a semi-experimental design with pre-test and post-test with control group. The statistical population consisted of all probation students of Razi University of Kermanshah. A simple random sampling method was used to select 40 students. Subjects were randomly assigned to two groups of experimental and control. The mean of the last semester was used as a pre-test and The mean of the current semester was used as a post-test. The experimental group was involved in cognitive rehabilitation intervention using the captain log program (10 sessions and 2 sessions a week) and the control group did not receive intervention during this period. Data were analyzed using SPSS version 23 software. Results: The results of the data show that there was a significant difference between the two groups after the cognitive rehabilitation exercises in the mean score (0.01). Conclusion: Thus, it can be concluded that the cognitive rehabilitation of the executive functions Improving the academic performance of probative students has a significant effect.

Introduction: Computer games, due to their expansion and popularity, have become one of the favorite topics of researchers in the field of brain and its function. The aim of this study was to evaluate computer skills in computer games and to examine the two networks of anterior and posterior attention. Method: The present study is a quasi-experimental method and two groups of profetional and notice participate in computer games. participant in both groups responded to the task during the EEG recording. The components studied in this study were the P1 component in the posterior attentional network and the posterior area and the PP2 component in the anterior attentional network and pre-forehead areas. Results: The results showed that the two profetional groups and so on are different in response to computer games and the notice group showed more activity in the face of stimuli. While the profetional group performed better and used both attention networks simultaneously. The results also showed that the two anterior and posterior attentional networks act differently in the face of stimuli, and the anterior network is more active in focusing attention. Conclusion: According to the obtained results, it can be said that computer games are associated with less activity and better but non-specialized performance in the brain, and this difference can be clearly seen in the anterior attention network.

Aim: The main aim of the present research was to compile a cognitive rehabilitation program and study its efficacy on cognitive functions and satisfaction of life in the erderly with mild Alzheimer’s. Methods: The research method of this study was a Quasi-experimental method with pretest-posttest designs with control group with one month follow-up. Statistical population was all the elderly with mild Alzheimer's living in the elderly residential care centers in Shemiranat in Tehran provinc, in winter of 2018-2019 and spring and summer of 2019. The sample included 50 participants with mild Alzheime's by the physician's diagnosis and getting score between 20-25 in Mini-Mental State Examination(MMSE) meeting the other inclusion criteria of this study, was selected through purposive sampling and then the participants were assigned in experimental(25 patients) and control group(25 patients) by random assignment technique. The experimental group trained 45 minutes-1 hour twice a week for 20 sessions of cognitive rehabilitation intervention. Training of the control group was postponed for the another time. Data were collected by Wechsler Memory Scale Questionnaire(WMS-Q), Wisconsin Card Sorting Test(WCST), Cognitive Empowerment of the Elderly of Individual Changes Questionnaire(CEEIC-Q) and Life Satisfaction Index-Z(LSI-Z) in the elderly. The data were analyzed through repeated measures analysis of covariance. Findings: The results showed that scores in(WMS-Q),(WCST),(CEEIC-Q) and(LSI-Z) had significant increase in the experimental group and fowllow-up showed These effects were maintained for one month. Conclusion: it can be concluded that cognitive rehabilitation was useful for repairing cognitive impairments and improving life satisfaction in the elderly with Alzheime's and it is recommended to use this technique as a non-pharmacological treatment in these patients.

Introduction: The present study, with emphasis on CaR-FA-X Williams model, investigates the intermediate role of over-general autobiographical memory on the relationship between impairment executive functions with ineffective problem-solving in depressed people.Methods: For this purpose, 56 subjects with major depression by sampling method during the period from April to September 2017 were selected . For data collection, after diagnosis of major depression by a psychologist, Autobiographical Memory Test, a problem-solving problem test and a Wisconsin card software were used. To analyze the research data using SPSS and IMOS software and path analysis method, structural equation modeling was used.Results: The results showed that the direct effect of executive function on problem solving with a value of 0/283 is not significant at the level of 0/05. The indirect effect of executive function on problem solving with a value of 0/130 is significant at the level of 0/05. The total effect of the executive function on problem solving is 0/413, which is significant at the level of 0/05. Therefore, due to the insignificant direct and significant effects of indirect effect, oral memory is a general mediator variable in the effect between the executive function on problem solving.Conclusion:Therefore, the present study, confirmed by the Williams CaR-FA-X model, showed that depressed people, due to their negative mood, and impairment in executive functions, have a particular problem in restoring their memoirs, and this is a problem in retrieval, solving problems It also affects their problems and makes them produce less effective solutions. Therefore, more generative of autobiographcal memory as a mediating mechanism in the relationship between impairment in executive function and ineffective problem-solving in depressed people.

Introduction: This survey was done in order to consider the impact of transcranial direct current stimulation on the visual/spatial working memory in the area of dorsolateral prefrontal cortex. Methods: This survey plan was experimental in the kind of pretest/after test together placebo group and arbitrary selection. The study sample contains 20 boy students with dyslexia with 8 to 10 years old that have inclusion criteria in this study. Two kinds of anode and sham stimulation, with 1.5 mA circuitry for 20 minutes and 15 minutes phonological awareness training on 20 participants in 10 sessions were presented. The participants before and after stimulation with N- Beck task, Shirazi and Nilipour reading test were tested. Findings: The covariance results showed that anode stimulation has a significant impact on improving performance in the visual/spatial aspect of the working memory compared to the sham stimulation. Conclusion: Overall, this study showed that the anode stimulation increased and improved individual performance on tasks involving visual working memory and has led to improved dyslexia in children.

Introduction: Due to the important role of the brain and frontal area, especially the prefrontal cortex, in decision-making and also proposing defects in the functioning of frontal area in alexithymia, the aim of the present study was to examine the relationship between decision making styles and alexithymia. Method: In the present descriptive-correlational study, 257 university students (114 males and 143 females) were selected among Payam Noor Universities of Bonab and Tabriz by multistage random sampling and both Making Styles Questionnaire of Scott and Bruce (1995) and Twenty-Item Toronto Alexithymia Scale were administered among the subjects. The obtained data were analyzed by Pearson correlation test and multiple linear regression analysis. Findings: The results approved the predictive role of alexithymia in explaining the decision making styles of rational, avoidance, and intuitive. As predicted, increasing alexithymia leads to increasing rational decision making style, and decreasing avoidance and intuitive decision making styles. However, among three factors of alexithymia, concrete thinking was recognized as the only effective factor in rational decision making style, and difficulty in identifying emotions as the only effective factor on avoidance and intuitive decision making styles. Conclusion: It seems that there should be common points in the biological basis of decision making and alexithymia. This defect is most likely to occur in the prefrontal cortex function which is activated in ethical decision making, and defects in exchanging information from its right side to the left side.
