On the Verification of the Principle of Reflex Visual Sensations*

Abstract

SYNOPSISSection I. of this communication contains a brief resume of Allen’s work on Reflex Sensations.Section II. contains descriptions of experiments made by fatiguing the left eye with various colors and then measuring the reflex effects upon the color sensations in the right eye, which is maintained in daylight adaptation.Section III. contains descriptions of the fatigue and reflex effects of color stimuli when applied to the right eye, the left being maintained in daylight adaptation. The direct and reflex effects of white light and darkness are also studied.Section IV. contains theoretical discussions relative to some of Burch’s experiments on fatigue, and to the brief initial overshooting of sensations when colored light is first applied to the eye. The experimental results are shown to support the trichromatic theory of Young and Helmholtz.
