Aim: The present investigate was conducted with the aim of the effect of cognitive fatigue on working memory and executive functions in female students. Method: The present study was a quasi-experimental study with pretest-posttest design with a control group,The statistical population of this research includeds the female students of the first secondary school in Urmia city in the academic year of 1400-1401,which is available by random sampling method 30 students selected and were simple randomly divided into two experimental (n=15) and control groups (n=15). The experiment consisted of second phases.In the first stage, the participants were exposed to cognitive tasks and then in the second stage, the Behavior Rating Inventory of Executive and N-Back working memory test was performed to compare the groups based on the amount of cognitive fatigue.The data were analysed by analysis of Covariance. Findings: The results of data analysis using covariance analysis showed decrease in working memory and executive functions in the experimental group compared to the control group. Conclusion: In general, the findings of the current research on the role of cognitive fatigue variables, which reduces the amount of working memory and executive functions And on the other hand, this type of fatigue is related to cognitive and brain functions.

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.

Aim: Cognitive rehabilitation is considered as an effective intervention in promoting the cognitive functions of patients with post-traumatic stress disorder. This study aimed to systematically evaluate the effectiveness of cognitive rehabilitation on improving the cognitive functions of patients with post-traumatic stress disorder. Method: For this purpose, all articles published in the period 2000 to 2020 were reviewed, to find related English studies, Google Scholar Databases, Science Direct, Scopus, Academia, Cochrane Database, Research Gate, and biomedical databases include PubMed, Medline, Psych Info, and rehabilitation databases including PEDRO, OTseeker, Rehab data and to find related studies in Persian, Google Scholar (Persian), SID, Magiran, IranDoc, MedLib, NoorMags, IranMedex databases, to Search with English and Persian keywords. Findings: 930 articles published in English and Persian were retrieved, and finally 12 related articles were reviewed. In this study, most studies focused on a limited range of cognitive functions. Conclusion: The results indicate the improvement of cognitive functions (memory, executive function and attention) in patients with post-traumatic stress disorder after cognitive rehabilitation. According to the results of studies, it can be stated that cognitive rehabilitation as an intervention can be effective along with other therapeutic interventions in promoting of cognitive functions in patients with post-traumatic stress disorder.
