This study aimed to analyze the effects of Knowledge of Results (KR) precision on acquisition of a motor ability. Forty eight children aged between eight and 10 years old (♂ = 9.33 ± 0.70 years old; ♀ = 9.16 ± 0.81 years old) practiced a manipulative task of reaching a target on a table, by the thrown of metallic discs. Three experimental groups were formed according to the KR precision level: less precise group (LPG), precise group (PG) and very precise group (VPG), and also the control group (CG), without KR. The performance measure was the absolute error. The results indicated statistic differences in favor of VPG when compared to the other groups, indicating that higher KR precision benefited the system´s stabilization and adaptability for task with accuracy goal, for children.

Keywords : Learning; Knowledge of Results; Practice; Psychomotor Performance.
