The Mentally retarded children have low intelligence, but the educational conditions, the living environment and the relationship they have with the people around them, especially their parents, have an important effect on their potential abilities. The aim of this study was to investigate the effectiveness of transcranial direct electrical stimulation of the brain (TDCS) on the components of working memory in children with mental retardation. The research method was applied in terms of objective and semi-experimental in terms of data collection with a pre-test-post-test design with a control group. The statistical population included all mentally retarded children aged 5 to 12 years old in the "Nilofrane" rehabilitation center for the mentally disabled in Zahedan city in the year 2022-2023, and there were 70 of them, 30 of them using the sampling method. Targeted selection and random replacement were placed in the experimental and control groups (15 people in the experimental group / 15 people in the control group). The experimental group received transcranial direct electrical stimulation (TDCS) program, while the control group did not receive training. The research tool was the set of children's working memory test by Susan Pickering and Susan Goderkol (2001). The data were analyzed using covariance analysis and SPSS version 22 software. The results of multivariate covariance analysis showed that the effectiveness of transcranial direct electrical stimulation of the brain (TDCS) had a significant effect on memory and its components (central executive, visual spatial plane and phonological loop).
