ABSOLUTE JUDGEMENTS OF VELOCITY

Abstract

The maximum amount of information transmitted by observers in the absolute judgment of velocity was determined. The study was subdivided into a series of five experiments in which 2, 4, 7, 10 or 19 sweep velocities of a 4-1/2 inch cathode ray tube--ranging from .70 inches per second to 300 inches per second (3.90 degre s per second to 1688.70 degrees per second of visual angle)-were presented to four subjects who were required to identify the stimuli with numbers ranging from 1 to 19. An informational analysis indicated that as the amount of stimulus information was increased the amount of transmitted information also increased, but at a decreasing r te, until a maximum of 2.23 bits of information was transmitted. Although anchoring ffec s occurred at both ends of the stimulus continuum, the low velocities were more accurately identified than were the high velocities. (Author)
