Overcoming problems and solving them, and maintaining mental and physical health in life, is very important. By improving cognitive abilities and increasing the processing speed of the mind, it is possible to improve the quality and health of life throughout life. The main goal of this research is to investigate the effect of transcranial direct current electrical stimulation (tDCS) on cognitive flexibility, problem solving and brain processing speed in students. This research was conducted as a semi-experimental design with a pre-test and post-test and a one-month follow-up phase. In this research, 30 people were selected as a sample using the purposeful sampling method and they were randomly divided into two experimental and control groups. The tDCS test group was subjected to electrical stimulation during two weeks and in 10 sessions, with a current intensity of 2 milliamps and for 20 minutes. At first, after finishing the stimulation program, and also one month later, tests of cognitive flexibility, problem solving and brain processing speed were taken from both groups and the results were analyzed using covariance test with repeated measurements. Based on the obtained results, it was observed that the difference between the groups is significant and indicates a positive and significant effect of intracranial direct current stimulation on cognitive flexibility, problem solving and brain processing speed. Also, according to the one-month follow-up phase, the mentioned effects are stable.

Introduction: The aim of this study was to evaluate the effectiveness of Captain Log software training on processing speed, working memory and cognitive flexibility in children with attention deficit / hyper-activity disorder. Methods: From children aged 7 to 9 years with attention deficit / hyperactivity disorder referred to health centers of East Azerbaijan province, 30 people were selected using purposive sampling method and in this quasi-experimental study of pre-test-post-test type They participated with two control and experimental groups. Data collection was performed using three subscales tests (cryptographic test, symbolization test and digit memory expanse test) Wechsler intelligence test for children and visual memory subscale of Wexler memory test and Wisconsin card classification test. Mean data and standard deviation were used to analyze the data in the inferential statistics section and repeated measures analysis of variance was used in the analytical statistics section.The mean difference in the three variables showed that processing speed and working memory And cognitive flexibility (P<0/0001) is significant in children trained with software and untrained children. Conclusion: The results showed that the training of Captain Log cognitive software caused active memory in children with attention deficit / hyperactivity disorder.

Introduction:One of the serious injuries caused by substance abuse is Brain damage and cognitive defects, which has a fundamental theoretical and clinical significance. The aim of this study was to compare of Brain Behavioral Activation and Inhibition activity mechanism (BAS/BIS), cognitive flexibility function in substance abuse disorder & normal women. Method: The present study was comparative-causal schemes. The statistical population of this study included all normal and substance dependent women in addiction treatment camps in Isfahan. The sample consisted of 30 dependent women (purposeful sampling method) and 30 healthy women (cluster sampling method). The tools were simple Stroop test software, Wisconsin test software and researcher-made demographic questionnaire. Findings: The results showed that there is a significant difference in Behavioral Activation System (BAS) and cognitive flexibility function. As in Wisconsin's psychological nursing test The drug-dependent group had a weaker performance than the normal group.But there was no significant difference between the two groups at the Behavioral Inhibition System(BIS). Conclusion: used to drug Shows more and longer deficits In the prefrontal cortex of the brain and the psychological nerve functions (executive). Investigating the neuro-behavioral foundations in the drug-dependent community can help the clinicians to use appropriate therapies and Preventive interventions in addiction.

Introduction: The aim of this study was to evaluate the effectiveness of neurofeedback education in improving the performance of attention and cognitive flexibility in athletic students. Method: To this end, 40 male students of physical education at Kharazmi University were randomly assigned to two groups of 20. The first group received 16 sessions of neurofeedback training (2 sessions per week) as the experimental group, and the second group (control) received no intervention. The research tools consisted of the Stroop Attention Computer Test and the Wisconsin Cognitive Flexibility Computer Test. The data were analyzed using one-variable and multivariate analysis of covariance and analyzed using SPSS19 software. Findings: The results showed that the experimental group had statistically superiority (p

Introduction: The aim of this study is to survey of the role of excecutive function (cognitive flexibility, cognitive inhibition, Continuous attention) on cognitive emotion regulation in Girl teens. Methods: The statistical population of this research is all students of high school students in Khormoj city who have been educated in 95-95 years. The sample consists of 117 adolescent secondary school students who were selected using multi-stage cluster sampling The research tools are the scale of emotional cognitive regulation strategies, Wisconsin software, Stroop and continuous performance. The data were analyzed by stepwise multiple regression. Findings: The results of the analysis showed that cognitive flexibility and inhibition can predict self-blame, flexibility, inhibition, and continuous attention; predictive of rumination; cognitive flexibility and cognitive restraint predictive positive retention strategies; cognitive flexibility and continuous attention Forecasting reassessment and continuous attention and anticipatory deterrence has been the development of perspective. Also, cognitive impairment has been able to predict the extent of disaster in teenagers in the sample group. Conclusion: These results provide guidelines for improving cognitive-emotional regulation strategies using executive functions.
