This study was conducted with the aim of comparing the effectiveness of sensory-motor games and neurofeedback on the working memory of children with attention deficit and hyperactivity disorder. This research is one of the types of semi-experimental studies in which subjects were selected from all 8-12-year-old children in Tehran with hyperactivity and were randomly assigned to experimental and control groups. 40 subjects were placed in three groups of sensory-motor games, neurofeedback, a combined group, and a control group, and before and after the interventions, the revised Wechsler intelligence scale for children -4th version WISC-R- was used to measure working memory. The findings obtained from covariance analysis after meeting the defaults showed that the amount of working memory in sensori-motor, neurofeedback and combined games in the group and the control are significantly different after removing the effect of the pre-test. This result means that according to the mentioned results, the intervention of sensory-motor, neurofeedback and combined games has a significant effect on the amount of active memory. Also, based on the findings, the combined approach of sensory-motor games and neurofeedback on children's working memory is more effective than the two approaches of sensory-motor games and neurofeedback, and there is a significant difference between the two approaches of sensory-motor games and neurofeedback in their effectiveness on active memory. does not have.
