This study aims to better understand the effect of practice schedule and feedback providing types. In two separate experiments the contextual interference effect in bandwidth and self-control feedback conditions on relative and absolute timing learning was examined. In experiment I, the effect of contextual interference using bandwidth and self-control feedback on absolute timing learning (parameters) was studied. Results in the acquisition test showed the performance of blocked self-control and bandwidth groups were significantly better than other groups (P<0.05). There was no significant difference in retention and transfer tests (P>0.05). In experiment II, the effects of contextual interference with using a bandwidth and self-control feedback on relative timing learning (GMP) were studied. . In retention and transfer tests, the performance of random self-control and bandwidth groups was significantly different to the other groups (P<0.05). The performance of self-control feedback groups in both experiments was better than bandwidth feedback groups (P<0.05) in all stages. The results of this study reveal the beneficial effect of self-control feedback on relative timing (GMP) rather than absolute timing (parameter) learning and supported the theoretical separation of this processes.
