Learning effects of knowledge of results upon time estimation.
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.
