Abstract

Measurements were made of the time interval between the primary stimulus and the moment of disappearance of every trace of the after-image for flashes of very intense lights of variable duration. The results can be explained on the assumption that the duration of the after-image is determined by the time that it takes for the product of a photochemical reaction to fall to some threshold value. Certain predictions from this hypothesis are experimentally verified.
