THE EFFECTS OF MOVEMENT-INDUCED 'NOISE' AND CUES ON PERCEPTION.
Abstract
The experiment was designed to determine whether recognition performance would be improved or retarded with the use of non-static visual stimuli as opposed to static images. The stimulus objects were rocket-like projectiles, animated by an analog-digital computer. The stimuli varied across several dimensions of similarity and S's task was to 'recognize' the stimulus object which was presented for 1.5 sec. periods. The stimulus presentations differed as a function of speed of motion where motion was varied across two dimensions (horizontal and vertical). The Ss were paid a bonus for correct responses with the bonus decreasing as a function of the time it took to make the decision. The prime dependent measure was choice reaction time. The present results, which should be considered preliminary, suggested that performance could be improved by motion. That is, motion might possibly provide an advantageous ratio between information and interference. (Author)
