Abstract
Fourteen studies from the literature on the reaction time (RT) to a flash of light provided sufficient methodological detail and data to allow a quantitative analysis of the effects of, the following selected variables: luminance, duration, size of stimulus, response to onset versus termination of the signal, and monocular versus binocular viewing. Mathematical relationships were developed that can be used to predict binocular RT's over a wide range of luminance, signal duration, and signal size.
