Abstract
Disinhibition was examined in the concentric circles aftereffect. Three conditions of luminance contrast, test figure (TF) and three conditions of contour width of TF were incorporated in the design together with two contour-width conditions of the inducing figure (IF). The results were significant for the IF widths as well as for the TF luminance and width gradients—strength of the aftereffect showed a direct relationship to the IF contour width and an inverse relationship to the TF luminance contrast and contour width. The results support Ganz’ simultaneous illusion theory of aftereffects.
