The study examined the effects of five variables: knowledge of results, distance, stimulus gradient, target speed, and temporal delay (a measure of temporal relationship between the target and standard) on the accuracy with which 3s could predict the arrival of a moving target at the position of a stationary standard.

The results of an analysis of variance on the data obtained from 52 Ss indicated that the variables of knowledge of results, distance.- speed, and temporal delay had statistically significant effects; but no statistical significance was indicated for effects of the gradient variable. Three statistically significant interactions were also indicated: knowledge of results x distance, knowledge of results x speed, and knowledge of results x temporal delay.

Evidence was provided which showed that the three statistically significant interactions involving knowledge of results determined, to some extent, the nature of the significant differences between the levels within the main effects of distance, speed, and temporal delay.
