Objective : The purpose of this study was to investigate the effect of knowledge of results (KP) and performance of results (KR) on motor learning in adult with mental retardation.
Methods : One female subject participated in experiment. The study employed alternative treatment design. The learning tasks were two different typing with functional independence. Subject practiced typing provided with knowledge of results and performance in motor learning skill after baseline measurement. Performance time and error(%) were measured and analysed at baseline, immediately after practice, 1 hour later after practice, and 2 days later in the end of practice for retention.
Results : Performance time and error were decreased after applying both interventions. Immediately after practice, the reduction of performance time was increased in KP more than in KR. But, in 1 hour later after practice, and 2 days later in the end of practice, the reduction of performance time was increased in KR more than in KP. The percentage of error reduced in KR more than in KP at all sessions.
Conclusion : The practice with KR facilitated and maintained motor learning skills more than with KP. It suggest that practice with KR is desirable for improving of motor learning skill in adult with mental retardation.
