Description
Summary:The Köhler-Wallach explanation of figural after-effects in electrical field postulates is challenged and a substitute theory based on orthodox nerve physiology is advanced. The thesis is proposed that such after-effects are due to differential adaptation within the projection system, produced by the prolonged inspection of contours. The basic postulate suggested is that rate of recovery from adaptation is a negatively accelerated function of its degree. The views advanced depend on the "statistical hypothesis" of Marshall and Talbot. Explanations are offered of all of the phenomena reported by Kohler and Wallach. Although the theory is presented as a substitute account it is admitted that the Köhler-Wallach views are not disproved.
