Movement pattern components and mastery of an object control skill with error-reduced learning: Brief report
ObjectivesThis paper reports the effects of error-reduced learning on movement components and mastery of overhand throwing in children with and without intellectual disability.
MethodsSecondary data analysis was performed on two samples of children (typically developing, TD; intellectual disability, ID) who practiced overhand throwing in either an error-reduced (ER) or errorstrewn (ES) condition. Movement pattern components were assessed using a sub-skill of Test of Gross Motor Development-2.
ResultsIn TD participants, ER learners displayed improved follow-through while ES learners did not. Among children with ID, ER learners displayed greater improvements of hip/shoulder rotation and followthrough, than ES learners. Discriminant function analysis confirmed that changes in these components differentiated learning groups. Greater percentage of ER, compared to ES, participants progressed to mastery.
ConclusionsWith suppressed errors, the follow-through component of overhand throwing is likely to emerge, particularly in children with inferior abilities, and working memory limitations. Error-reduced learning facilitates mastery.
