| Abstract: | The purpose of this study was to determine the effects of knowledge of results (KR) on the acquisition of a coincident-timing task. Specifically, the purposes of this study were as follows: (1) to determine the effects of the precision of KR and practice on the accuracy of performance of a coincident-timing tasks (Experiment 1), and (2) to determine the effects of a graduated KR schedule and practice on the accuracy of performance of a coincident-timing task (Experiment 2). The task for both experiments required each subject to execute a right to left arm-hand movement to five targets and attempt to terminate that movement coincident with the lighting of the last of a series of runaway lights. Experiment 1, five groups numbering six subjects each were assigned to one of the following degrees of KR precision: (1) no Kr, (2) directional KR, (3) directional and quantitative KR to tenths-of-a-second, (4) directional and quantitative KR to hundredths-of-a-second, and (5) directional and quantitative KR to thousandths-of-a-second. Subjects performed 5 blocks of 25 trials on each of four consecutive days with KR administered to each subject following each trial, dependent upon his/her treatment group. Two groups of six subjects each followed the same procedures in Experiment 2 with the exception that the KR conditions consisted of (1) directional and quantitative KR to thousandths-of-a-second, and (2) a schedule of KR that increased in precision as a function of practice. ... |
