Objective: The present study evaluates the effects of cognitive rehabilitation on remediation of recognition of emotional states in children with high-functioning autism disorder. Method: In this single-subject design study, 4 children with high-functioning autism participated with an intact sampling method, and receive 14 sessions of cognitive rehabilitation. Benton Face Recognition Test was administered in 6 series of time (2 week and immediately before intervention, after 4^th, 10^th and 14^th session and 2 week after intervention as follow up). Data analysis was performed by visual analysis, and effect size was computed subsequently. Results: The results showed that the subjects' performance improved significantly. As well, the effect of the training program was effective in distinguishing emotional states. Conclusion: This study showed that short-term intensive training could be helpful in remediation emotional states distinguishing ability in children with autism. This study supports the efficacy of “Persia Program” in improving the emotional states distinguishing skills in these children.
