RELATION OF SLANT AND SHAPE JUDGMENTS IN REDUCED VIEWING,

Abstract

Observers estimated the slant and drew the apparent shape of a homogeneous white circle and a similar rectangle under monocular and binocular reduction conditions for zero and four degrees of geometric slant. In terms of the requirement that, when slant is underestimated relative to geometric slant, but is significantly greater than zero, shape estimates should approach, but not coincide with, the projective shape, the results failed to support the invariance hypothesis. The findings are discussed in relation to the view that the hypothesis should be tested without reference to the projective geometry of the stimuli. (Author)
