Abstract:
Misapplied-size-constancy, assimilation, and contrast theories are discussed as explanations for the Wundt-Jastrow and Ponzo illusions. An experiment is reported that questions the need to include a contrast function in the assimilation theory of Pressey and Wilson to account for the Wundt-Jastrow illusion. Several directions for further research are proposed.
