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.
以40名女大学生为受试者，研究了不同KR精度水平对线性定位任务初始习得和后期表现的影响。记录了表现的主观评价、准确性估计以及实际得分。KR精度水平（厘米或毫米）不影响实际表现，但极其精确的KR（毫米）对表现评价和估计表现的标注过程有不利影响。
