TANI, Go; MEIRA JR., Cássio M.  and  GOMES, Fábio R. F.. Frequency, precision and temporal localization of knowledge of results and the adaptive process in the acquisition of a manual force control skill. Rev. Port. Cien. Desp. [online]. 2005, vol.5, n.1, pp.59-68. ISSN 1645-0523.

In motor skill acquisition, not only functional stability is important, but also the capability of applying what was acquired to new contexts; this characterises a cyclic and dynamic process of instability-stability-instability, which results in increasing complexity. This study aimed to investigate the role of knowledge of results (KR) in motor learning viewed as an adaptive process. According to the results, KR regimes of low frequency and precision, and with interpolated activity on post-KR interval (factors of instability, uncertainty and disorder) were not prejudicial to adaptive process in acquiring a manual force control motor task.

Keywords : knowledge of results (KR); feedback; force control; adaptive process; motor skill acquisition; motor learning.
