Aim: One of the most common problems in people with multiple sclerosis)MS) is memory impairment. Although the effect of dual cognitive motor tasks assignments on cognitive function in MS patients have been confirmed, however little research has been done its effect on their spatial memory. Therefore, the aim of this study was to improve spatial memory of MS patients because of dual tasks training. Method: The present study's design was pre-test and post-test with random group method. The research method was semi-experimental and in terms of purpose was applied. To did this research, Thirty women with MS)20-60 years old) who were members of the MS Association of Tehran, participated voluntarity with informed consent in this study. participant were then randomly divided into control and experimental groups. the spatial memory pre-test was first taken from the subjects through spatial memory from the LM-01 spatial memory device. then subjects training Dual Task for eight weeks, each consisting of two 45-60 minutes sessions. The Post-test was done. The data were analyzed by mix analyasis and independent and paired t-test at a significant level of p < /em>≤0/05. Result: Results of analysis of variance showed that dual task training significantly improved spatial memory)p < /em> = 0.04) in the experimental group compared to the control group. Conclusion: Therefore, Dual Task training cognitive-motor assignments causes more mind involvement and can be considered as a suitable way to enhance cognitive abilities such as spatial memory.

Aim: Neurofeedback training is known as a useful and inexpensive tool for enhancing and improving in memory types, however, its effect on the visual and spatial memory has no been investigated yet. Therefore, the aim of this study was to improve visual and spatial memory because of neurofeedback training with an emphasis on decreasing beta wave and increasing SMR wave. Method: The present study’s design was a within group with a pre-test post-test method. The research method was semi-experimental and in terms of purpose was applied. To did this research, 11 students (mean age: 27.63 ± 2.76) participated voluntarily in this study. By obtaining informed consent, the visual memory pre-test was first taken from the subjects through short-term visual test of the Vienna and spatial memory through the LM-01 spatial memory device. Then subjects perform for 5 sessions of neurofeedback training protocol with an emphasis on decreasing beta wave and increasing SMR wave. After training completion, the post-test was done. The data were analyzed by paired t-test at a significant level of p≤0.05. Results: The results showed that neurofeedback training significantly improved visual memory (P≤0.020) and spatial memory (P≤0.013). Conclusion: Therefore, neurofeedback training can be considered as useful tools for improving cognitive abilities such as memory.

Introduction: One of the most important goals of any athlete optimum performance during the competitions, but sometimes athlete’s performance suddenly destroyed under psychological pressure caused by competition. This study investigated the effect of neurofeedback and under pressure training on expert archers’ performance in competitive condition. Methods: participants were 30 adult healthy right hand expert female archer in Tehran that were selected by accessible method and after primary archery record in competitive condition and sameness were assigned randomly into three groups: neurofeedback and under pressure training and control. Training protocol was done 12 sessions at 4 weeks and after training was performed renewed record in competitive condition. Findings: The results of analysis of variance showed that the performance of participants at posttest both neurofeedback and under pressure group than control group progressed significantly (p= 0.003), the other at this stage despite was higher average’s record of under pressure training group, not seen significant difference between the neurofeedback and under pressure group. Conclusion: According to the findings of this study, effects of neurofeedback training, particularly under pressure considered to promotion of expert archers performance and emphasized to use of these methods beside physical training to achieve better results in competitions.

Introduction: Emotional eavesdropping is information that observer receives by listening and watching emotional reactions directed by third party (as coach) to another (model). It seems mirror neurons system is one mechanism responsible for this but ways in which emotional eavesdropping discharges this neurons are not clear. So the aim of this study was to investigate the effect of emotional eavesdropping of model on mirror neurons activity (mu rhythm suppression). Methods: For this reason, 22 right hand novice athletes (average age 20/69±1/10) participate voluntary in this research. These participants observed three instructional video of free throw in basketball that also display emotional reactions (positive, neutral, negative) of coach and model about model performance. Four Brain waves records were done by electroencephalographic assessments: one base record with open eyes as index of mirror neurons activity in rest and three records during positive, neutral and negative emotional eavesdropping in three regions C3, C4 and Cz. Findings: 3×3 within subjects ANOVA findings demonstrated that mu rhythm suppressed during three emotional eavesdropping in three central regions. Post hoc results showed more significant mu rhythm suppression during negative emotional eavesdropping in C4 than other conditions. Conclusion: thus, these findings confirm valance hypothesis about negative emotion and right hemisphere hypothesis and it seems emotional eavesdropping modulate mirror neurons activity.
