abstract="On the basis of certain assumptions derived from the all-or-none hypothesis regarding the nature of the nerve processes of the retina, the authors have formulated quantitative expressions for the effect of bright and dark surroundings on the difference-threshold of foveal vision. Comparison of the values calculated from these formulae with the limens for brightness obtained in actual experiment reveals a substantial agreement between the two sets of data. The range of application of the formulae to various conditions in visual experimentation remains still to be determined. From Psych Bulletin 19:09:00581.
