The signs of carpal tunnel syndrome, resulting from median nerve damage and leading to chronic pain, numbness, and motor function weakness, are studied in neuroscience research. This is because persistent nerve injury can lead to structural and functional changes in motor neural pathways, which in turn can directly affect individuals’ bioemotional and cognitive functioning. So, The present study aimed to investigate the effectiveness of yoga training combined with a healthy lifestyle on improving carpal tunnel syndrome symptoms, sleep quality and duration, and cognitive functions in adolescents with internet gaming disorder in Tehran. This semi-experimental study utilized a pretest-posttest-follow-up design with a control group. The statistical population consisted of adolescents with internet gaming disorder and carpal tunnel syndrome symptoms who referred to counseling centers in Tehran . From this population, 30 individuals were selected using convenience sampling and randomly assigned to two groups: experimental (n=15) and control (n=15). Interventions consisted of 12 ninety-minute yoga sessions held at a counseling center. Research instruments included the Pittsburgh Sleep Quality Index and the Cognitive Abilities Questionnaire whose reliability and validity had been confirmed in previous and present studies. After completing the questionnaires in the pretest, posttest, and follow-up phases, data were analyzed using repeated measures ANOVA. The results showed yoga training combined with a healthy lifestyle improved sleep quality, increased sleep duration, and enhanced cognitive functions compared to the control group. This research highlights the importance of combined interventions in promoting the physical and mental health of adolescents with internet gaming disorder.

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.

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.

Aim: Cognitive functions are among important subjects of psychology. Decision making is a cognitive function that has been received too many attentions. The main aim of the research was to verify the effectiveness of Neurofeedback on risky decision making. Method: The study was done half experimentally. Therefore, 30 students was chosen by available sampling and set randomly in two 15 person experimental and control groups. The both experimental and control groups were evaluated with Balloon Analogue Risk Task (BART) in two before and after Neurofeedback learning steps. The experimental group was learned Neurofeedback 20 sessions, while the control group received no learning. Findings: Data were analyzed using single variable covariance analysis (ANCOVA). Results demonstrated that after 20 sessions Neurofeedback learning, students of experimental group had significant improvement in risk-taking decrease. . Conclusion: Neurofeedback is a brain waves operant conditioning in which people learn to control their brain waves voluntary and through that they can improve their functions such as decision making. Based on the results of this study, Neurofeedback is an appropriate approach to improve and reinforce the cognitive functions including decision making.

Introduction: The aim of the present study was to investigate the role of selective attention, test anxiety and cognitive performance in students' working memory. Method: The population of this study consisted of all high school students in Tabriz, who were studying in 2015-2016. A sample of 353 students were selected through cluster sampling. To collect the data from the Stroop test, Spielberger Test Anxiety Inventory and the Wechsler test and n-back test were used. Pearson correlation and multiple regression analysis methods (simultaneous) were used for data analysis. Findings: The results showed that there is a significant positive correlation between working memory and selective attention. However, the correlation between working memory and error is negative. There is negative and significant relationship between test anxiety and working memory. In addition, there is positive and significant relationship between cognitive functions of computing, image adjustments and cubic design, with working memory. There was no relationship between vocabularies with working memory. Also, regression analysis showed that the scores were predictive variables (selective attention test anxiety and cognitive functions) and 19% of working memory changes was significantly predicted. Conclusion: Therefore, it can be concluded that through increasing selection attention and cognitive functioning test anxiety can be reduced and the students working memory is improved.
