College students of both sexes served as their own controls to test three hypotheses in each of two separate experiments designed to assess the learning effects of knowledge of results upon time estimation. The results indicated that (1) knowledge of results in the form of feedback to the nearest hundredth of a second significantly increased the mean accuracy of time estimations obtained by the method of production, (2) that knowledge of results significantly decreased the variance of the time estimations, and (3) that sex difference as a main effect was not significant in either experiment. A major conclusion of the present study was that variance represents an authentic and independent measure of learning.
在两个独立实验中，男女大学生都作为自身对照，以检验三个假设，这两个实验旨在评估结果知识对时间估计的学习效果。结果表明：（1）精确到百分之一秒的反馈形式的结果知识显著提高了通过生成法获得的时间估计的平均准确性；（2）结果知识显著降低了时间估计的方差；（3）在两个实验中，作为主要效应的性别差异均不显著。本研究的一个主要结论是，方差是学习的一种真实且独立的度量。
