Violations of visual simultaneity

Abstract

We present the result of two experiments that demonstrate an ability on the part of Os to detect asynchronies in visual stimuli with in the range of 0-100 msec. Such results are additional examples of an ability on the part of the human O to use information about temporal order to a precision beyond the usual results of visual "simultaneity" experiments. Thus the conventional nations of simultaneity and its corollary, the psychological moment, may be reflections of psychophysical technique rather than the biological function of sensory systems. © 1970 Psychonomic Society, Inc.
