FERREIRA, Gabriela Moara et al. Effects of self-controlled knowledge of results in motor learning. Motriz: rev. educ. fis. [online]. 2012, vol.18, n.3, pp.495-504. ISSN 1980-6574. http://dx.doi.org/10.1590/S1980-65742012000300010.
The purpose of this study was to examine three different strategies to provide knowledge of results (KR), yoked paired by trial and yoked paired by average of total frequency of KR in random practice. The sample was composed by 45 volunteers, distributed into three groups (n=15 subjects). The task consisted of press three keys, 2, 4, 8 and 6 in the numeric keypad of the computer in three different total time (700, 900 and 1100 ms) in random practice. The experiment consisted of acquisition phase and delay retention and transfer test. The data analysis was conducted by ANOVA and the results were not demonstrated difference between groups. The results showed no effect of self-controlled frequency of KR to the motor learning when using random practice. In addition, a new possibility to be used the yoked group was presented.
