The present study was designed to examine the effects of two kind of feedback presentation, namely KR and KP, on movement pattern and accuracy of a Badminton serve in children with autism. We used a causal-comparative method in the current study. Sixty children with autism with an age range of 7 to 12 years from special schools were selected based on a convenience sampling method and were randomly and equally assigned into four groups including KR, KP, KR+KP, and control groups. The motor task in the present study included the badminton serve, in which the movement patter and accuracy were measured as the dependent variable. The children participated in the pretest including 10 services, acquisition phase (5 training blocks, each of which included 10 services), and the retention test with 10 services. Respective feedback was provided before each practice block. We used ANOVA to analyze data. The results showed that both KR and KP feedback improve both the pattern and the accuracy of movement better than the condition without feedback. In addition, KP had better effects on the movement pattern and KR had better effects on the movement accuracy. Finally, children who were in the combination group performed better than all the groups in both execution of the movement pattern and service accuracy. Children with autism benefit from feedback to learn novel motor skills, indicating that they may have the necessary mechanisms to learn new skills through feedback.

The aim of this study was to investigate the effect of autonomy support (i.e., in the form of self-controlled feedback) on learning and self-efficacy in a throwing skill in adolescents with ADHD. The subjects were 40 adolescents with ADHD (14 to 17 years old) and were randomly and equally divided into two groups: self-controlled and yoked. Motor task consisted of throwing bean bags with the non-dominant arm at a target on the ground. The participants completed the pretest (10 trials), an acquisition phase including 6 blocks of 10 trials, and a retention test consisting of 10 trials. The participants in the self-controlled group received knowledge of result (KR) anytime the requested. The yoked group was matched with self-controlled group, but without having a choice to request for feedback. Prior to pretest, each block, and before the retention test, all participants completed the self-efficacy scale. Dependent measures were throwing accuracy scores and self-efficacy. Independent t-test and analysis of variance (ANOVA) with repeated measures were used to analyze the data. The results showed that participants in the self-controlled group had significantly higher throwing accuracy scores in the acquisition phase and the retention test than those in yoked group. Moreover, participants in the self-controlled group reported significantly higher self-efficacy scores in the acquisition phase and the retention test than those in yoked group. The results of this study show that people with ADHD benefit from autonomy support to learn a novel motor skill.
