Introduction: Several studies have examined the effect of visual illusion on both motor performance and cognitive task of estimating target size in normal individuals. But research that has used this approach on the cognitive function of children with autism and the underlying neurological mechanisms has been neglected. Therefore, the aim of the present study was to investigate the effects of Ebbinghaus visual illusion on changes in perception of target size and brain waves in children with autism.
Method: The research was quasi-experimental with pre-test and post-test design with 3 groups (2 experimental groups and one control group). The statistical population of the study included all right-handed autism Children with an age range of 8-10 years in Mashhad. 33 autism Children were selected by available sampling method and randomly divided into 3 groups of 11 people. The research instruments included visual illusion targets for training and an EEG device for recording brain waves. Analysis of covariance and analysis of variance with repeated measures were used to analyze the data.
Results: visual illusion has a significant effect on changes in target size and changes in alpha brain waves; So that the larger perceived group was more associated with alpha wave reduction.
Conclusion:  Due to the identification of the neural mechanism underlying visual illusion, it can be used as an effective training method in perceptual problems in children with autism.
