VIEIRA, Márcio Mário; UGRINOWITSCH, Herbert  e  BENDA, Rodolfo Novellino. Effects of delay KR, post-KR, and intertrial intervals in motor learning. Rev. educ. fis. UEM [online]. 2013, vol.24, n.2, pp.181-194. ISSN 1983-3083.  http://dx.doi.org/10.4025/reveducfis.v24.2.17820.

The supply of knowledge of results (KR) involves temporal aspects, which is the moment when KR is provided, and it is composed by three intervals: delay KR, post-KR interval, and intertrial interval. This study investigated these intervals in three different experiments. Ninety volunteers performed a positioning task with sequence and target time pre-established. Immediate and delayed transfer tests were performed in a new sequence and target time, without KR. A delayed transfer test was carried out 24 hours after acquisition phase. Three experiments were conducted to investigate the effects of KR delay, post-KR interval, and intertrial interval, respectively. The results showed differences among groups in KR delay and intertrial interval conditions. We conclude that the effects of KR delay and intertrials interval can be more effective for motor learning than the post-KR interval.

Palavras-chave : Feedback; KR-delay; Post-KR interval; Intertrial Interval.
