During the past decade several attempts have been made to formulate equations which would explain certain visual phenomena, namely flicker fusion frequency, brightness discrimination, visual acuity, and instantaneous thresholds as functions of intensity, and light and dark adaptation as functions of time. These various equations are based on several fundamental concepts regarding the mechanism by which the visual sensation is determined. Each concept has been explained by the original author at the time the theory was proposed, but no comparison of these basic ideas has yet appeared in the literature. The purpose of the present paper is to make such a comparison available.
