Background: Autism spectrum disorder (ASD) is a severe developmental disorder which leads to physical disability. Positive normative feedback can promote motor learning. Objectives: The aim of this study was to evaluate the effects of positive normative feedback on learning a throwing task among children with ASD. Methods: This quasi-experimental study was carried out on twenty children with ASD who aged 6–10 years. Children were assigned to a positive normative feedback and a control group. In the positive normative feedback group, children were trained to throw beanbags to a target point on the ground with their nondominant arms. The acquisition phase included six ten-trial sets. Children in both groups received veridical feedback after each trial. However, children in the positive normative feedback group also received bogus feedback (scores, which were 20% greater than their actual scores) about their performance in each set. A retention test was performed 24 h after the acquisition phase. The independent sample t-test and the repeated measures analysis of variance were used to analyze the data. Results: There was no significant difference between the groups regarding the performance mean score at baseline. Moreover, despite increases in the performance mean scores over time in both groups, between-group differences in the acquisition and the retention phases were not statistically significant (P > 0.05). Conclusion: Positive normative feedback does not have significant motivational effects on motor learning among children with ASD.
