Abstract
The effects of various size targets and the extent of the visual field on the accuracy of orientation in the homogeneous environment were investigated by requiring Ss to recenter four different targets, starting from 11 locations, in a 270° homogeneous field. The results showed that: (1) each S positioned all four targets in a preferred field, (2) small error scores and consistency in positioning around perceived centers were found with only three of the four targets, (3) in all cases the largest error and greatest variability was in centering the smallest target, (4) absolute errors were not related in any systematic fashion to the initial starting points, and (5) with respect to initial target presentations, i.e., left and right fields, S's errors tended to be smaller in the field containing that S's perceived center. It was suggested that the variability of the small target could be accounted for, in part, by the autokinetic effect.
