TY - JOUR PY - 1981// TI - A neglected problem: kinetic size constancy JO - Acta psychologica A1 - Noguchi, K. A1 - Taya, K. SP - 187 EP - 194 VL - 48 IS - 1-3 N2 - Size constancy in three-dimensional motion, "kinetic size constancy", was investigated by measuring both perceived size and perceived distance under monocular and binocular viewing conditions. It was found that forward-motion facilitated a tendency to see an object with an approximately constant size and made it possible to perceive veridically the distance to the object (distance constancy). The size-distance invariance hypothesis, expressed in the form S'/D'=K theta n, was found to hold in the present experimental situation. In contrast to static size constancy, with kinetic size constancy there is no requirement for separate depth cues if a focal stimulus changes along its vertical and horizontal dimensions and this results in the perception of a shape.
