Abstract
The effect of varying KR precision levels on the initial acquisition and later performance of a linear positioning task was investigated with 40 female undergraduates serving as subjects. Subjective evaluations of performance and estimates of accuracy were recorded along with actual scores. KR precision level (centimeters or millimeters) did not affect actual performance, but extremely precise KR (millimeters) had detrimental effects on performance evaluations and the labeling process of estimate performance.
