The effect of knowledge about the results of movements (KR) and self-estimates about such results were investigated. In a 2×2 factorial design, participants (N=61) first practiced a coordination motor task. Then they either estimated or did not estimate the results of previous movements they made. During acquisition, participants were provided KR either after every response, or after every third response. A no-KR retention test revealed an interaction between KR frequencies and self-estimates about the results of movements. When participants did not estimate the results of movements made during acquisition, retention was enhanced in the low KR frequency condition, compared to the high KR frequency condition. However, when participants did estimate the results of movements, high KR enhanced retention more than low KR.
