Abstract

This experiment is concerned with the distance at which a light spot disappears from the edge of a large inducing source. Considerations relative to luminance discrimination are introduced, and it is demonstrated that the results of the present experiment are describable as having some of the formal characteristics of that type of discrimination. It was observed that the border of the inducing field appeared to shift with luminance changes of the test spot. As a first approximation the results of this experiment could be accounted for by a stray-light hypothesis.
