Introduction: This survey was done in order to consider the impact of transcranial direct current stimulation on the visual/spatial working memory in the area of dorsolateral prefrontal cortex. Methods: This survey plan was experimental in the kind of pretest/after test together placebo group and arbitrary selection. The study sample contains 20 boy students with dyslexia with 8 to 10 years old that have inclusion criteria in this study. Two kinds of anode and sham stimulation, with 1.5 mA circuitry for 20 minutes and 15 minutes phonological awareness training on 20 participants in 10 sessions were presented. The participants before and after stimulation with N- Beck task, Shirazi and Nilipour reading test were tested. Findings: The covariance results showed that anode stimulation has a significant impact on improving performance in the visual/spatial aspect of the working memory compared to the sham stimulation. Conclusion: Overall, this study showed that the anode stimulation increased and improved individual performance on tasks involving visual working memory and has led to improved dyslexia in children.

Introduction: Given the importance of education and its impact on various aspects of physical and mental functions as well as lack of evidence on the effects of education on working memory performance, this study aimed to investigate the impact of educational level on the working memory. Method: In this correlational study, a sample of 202 participants of both sexes aged between 30-41 years who held degrees from diplomas to PhD were selected by convenience sampling and were evaluated using 1-back and 2-back tasks. The data were analyzed and compared by analysis of variances. Findings: Comparing the scores of 1-back and 2-back tasks, using ANOVA, F was calculated equal to 25.266 and 19.399 (p
