Induced motion was investigated as a function of the stereoscopic separation of the test and inducing object and the instructions to attend to or to ignore the inducing object. It was found that stereoscopically displacing the test object from the inducing object with both kinds of instructions resulted in a decrease in the magnitude of induction… (More)
This study assessed perceptual learning effects with complex random-dot stereograms. Observers were shown the same complex anaglyph five times daily, for four consecutive days, and latencies to achieve stereopsis were recorded. Two-factor repeated-measures analysis of variance yielded significant effects of days, trials, and days-by-trials interaction.… (More)
This study replicated and extended the findings of MacCracken and Hayes (1976). 10 students were presented the same complex stereogram for 5 trials daily over 2 nonconsecutive days, and latencies to achieve depth perception were recorded. Latencies decreased across 5 trials in the first session but were somewhat longer at the beginning of the second session… (More)
The effects of posthypnotic suggestion on the perception of egocentric distance were evaluated by two methods, one direct and the other indirect. The direct method was the verbal report of the perceived distance of the stimulus. The indirect method used a measure based on apparent concomitant motion of the stimulus with a lateral movement of the head. The… (More)
