spatial memory

The present study is done to compare working memory in monolingual and bilingual children with special learning disability. Design of research was causal-comparative. Statistical society of the research was elementary students in Tehran and Javanroud in the 1392-1393 years. A number of 60 children including 30 (15 gilrs and 15 boys) monolingual (Persian) and 30 (15 gilrs and 15 boys) bilinguals (Kurdish-Persian) were recruited from special learning disability rehabilitation centers by accessible sampling. Data were collected with Wechsler intellectual scale for children-revised (shahim,1390) and Wechsler’s subscale of working memory test (WWM). To analysis of data, descriptive and inferential statistic methods including average, standard deviation, independent t-test and Friedman test were done and analyzed by Spss 16. Results show that there is significant differences in spatial working memory (p < 0.05, t=-2.17) and working memory (p < 0.05, t=-2.14) between monolinguals and bilinguals. There was no significant difference in the letter-number sequence (p>0.05, t=-1.09). Based on the findings of the present study, it can conclude that bilingualism is associated with better working memory functions in bilingual children with SLD.

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.

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.

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.

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.

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. 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. The results showed that neurofeedback training significantly improved visual memory (P≤0.020) and spatial memory (P≤0.013). Therefore, neurofeedback training can be considered as useful tools for improving cognitive abilities such as memory.
