Abstract Introduction: The aim of the present study was to investigate the effect of manipulating the motivational-mastery-climate on the level of physical literacy in autistic children.
Methods: The present study is a quasi-experimental study with a pre-test-post-test design. The statistical population of the present study included autistic children in Shiraz, aged 8-10 years. For this purpose, 40 people were selected using the accessible and purposive sampling method and after obtaining written consent, they were randomly assigned to one of two groups: motivational-mastery-climate and control. The instrument used in this study was the physical literacy scale. The implementation method was that first, the physical literacy pre-test was taken from the subjects. Then, the research intervention was implemented in the form of a motivational-mastery-climate and a recreational training program (Control) for 12 weeks, three days a week and 60 minutes. After the intervention, the physical literacy post-test was taken from the subjects again. Data were analyzed using the analysis of covariance statistical method.
Results: The results of this study showed that there was a significant difference in physical literacy between the effectiveness of the motivational-mastery-climate intervention compared to the control group (recreational training program); this difference was in favor of the motivational-mastery-climate intervention group (sig=0.001).
Conclusion: Therefore, due to the greater effectiveness of motivational-mastery-climate intervention, it is suggested to trainers and therapists to use this method to enrich the conditions of their training interventions.

Abstract The purpose of this study was to investigate the effect of visual illusion on the learning of throwing skills in autism children. The research method was semi-experimental with repeated design and retention test. The statistical sample of this study was 33 children of 10 years old who were selected available and were divided into three groups randomly: larger circle perceptions, smaller circle perceptions and control group. The tool used in this study was the Ebbinghaus illusion displayed on the ground and the beanbags for throwing from down to shoulder to goal. At first, the participants performed ten trials at the pre-test phase. Then, in the acquisition phase, 20 blocks completed 10 trials. 48 hours after the last session of the acquisition, a retention test was performed in 10 trials of the participant. To analyze the data, mixed analysis of variance analysis with repeated measures, one way analysis of variance and Tukey's follow-up were used. The results of this study showed that there was a significant difference between the groups both in the acquisition phase and in the retention phase between the groups, which this difference was in favor of the larger circle's perception group. Overall, the results of this study showed that a simple perceptual manipulation can increase motor learning in children with autism. Therefore, it is suggested to educators and sports practitioners to use this variable to improve their performance and improve their training sessions.
