Visual autokinesis as a function of the amount of “possible” movement

Abstract

Reports of autokinetic movement were obtained from 10 male and 10 female Ss when the Ugh t was remembered as appearing in a large (15 in. square) window or in a small (5 in. square) window. The effect of exposure duration (10 sec vs 20 sec), trial blocks, and sex of S were also varied in the 2 by 2 by 2 by Ss design. More movement was reported for the large window (pK.025), the 20-sec duration (p <.001), and the first trial block (p < 025). No other effects were significant The results were discussed in terms of a cognitive organization imposed upon the inherently ambiguous perceptual situation.
