The use of metacognition differs with different levels of cognitive ability, but it is not known whether children of different psychomotor abilities use metacognition differently. This study used a think-aloud protocol to compare the active use of metacognition in children with different psychomotor abilities—high skill, average, developmental coordination disorder (DCD)—during a ball-throwing task. Children with DCD did not verbalize fewer or different metacognitive concepts than either the average or high skill children; however, relative to their counterparts, a significant median proportion of the concepts verbalized by children with DCD were found to be inappropriate or inaccurate. These findings reflect ineffective metacognitive processing by children with DCD during a psychomotor task.
