This study examined the effects of self-controlled versus instructor-controlled demonstration on learning basketball free throws in children with different motor imagery abilities. Forty boys aged 9–12 were randomly assigned to four groups based on imagery ability (high/low) and demonstration type (self/instructor-controlled).
