This study examined the effect of subject-controlled knowledge of result (KR) in learning a golf putt task. Participants were required to stroke a plastic golf ball as close as possible to a line five meters away. A screen was positioned to prevent vision of the rolling ball and its final stop position. Three groups were compared: a 100% KR group, subject-controlled KR group and yoked KR group (which received the same proportion of KR as the subject-controlled group, but controlled by the experimenter, which was about 50% of the trials). Subjects in each of the three groups practiced 30 trials on each of three days. A 10-trial retention test, performed 3 days after 3rd day of practice, revealed that the subject-controlled KR group was significantly better than both the 100% KR and the yoked KR groups. Therefore we conclude that subject-controlled KR is effective not because KR was provided with less frequency but rather because KR was provided according to participants' request.
