A further investigation of visual dominance

Abstract

It has previously been shown that when human subjects are presented simultaneously with a light and a tone, each of which serve as a cue in a reaction time task, the subjects respond predominantly to the light. This visual dominance effect may be due to the "hard wiring" of the sensory systems involved, or the effect may be nonsensory in nature, being based on decisional or attentional factors. The present experiment suggests that visual dominance has a nonsensory basis, in that the effect is even more evident when subjects respond to stimulus offset rather than stimulus onset. © 1979 Psychonomic Society, Inc.
