EFFECTS OF REDUCING FREQUENCY OF INTRINSIC KNOWLEDGE OF RESULTS ON THE LEARNING OF A MOTOR SKILL

The guidance hypothesis suggests too much knowledge of results during skill acquisition can be detrimental to long-term performance. Possibly, the learner becomes dependent on augmented KR and is unable to use intrinsic feedback. This study examined this hypothesis with three groups performing a golf putting task. One group received continuous KR about ball path and final location; the other groups were deprived of specific KR on 50% or 100% of the acquisition trials. As expected, the continuous KR group performed better during acquisition, but the KR-deprived groups performed better on delayed retention trials, especially when KR was absent.
