  • Title: Shape constancy and polar perspective.
    Author: Wallach H, Marshall FJ.
    Journal: J Exp Psychol Hum Percept Perform; 1986 Aug; 12(3):338-42. PubMed ID: 2943862.
    Abstract:
    The distortion of polar perspective depends on the depth of the tridimensional shape and on the observation distance. In four experiments using 54 undergraduates as subjects, we found that a compensation process which takes depth and observation distance into account corrects for such distortions. Compensation was demonstrated in experiments in which deceptive information on depth and on observation distance was provided. The result was distortions of the perceived shapes that would be expected if compensation were based on the deceptive information.
