Abstract

It should be investigated whether the degree of constancy is variable in accordance with the magnitude of object even when the relative position between the object and the observation point remains the same. The objects are seven square walls, 2.5m×2.5m, 1.667m×1.667m, 1.111m×1.111m, 0.741m×0.741m, 0.494m×0.494m, 0.329m×0.329m, 0.219m×0.219m. The selection method was employed. The subjects are fixed, and the objects are moved. Main conclusions-1. The smaller the magnitude of object is, the higher the degree of constancy. We named it "Magnitude Effect". 2. The larger the observation distance is, the more conspicuous "magnitude effect". 3. In peculiar points, over constancy of shape appears. 4. Regardless of the magnitude object, the larger the distance is and the smaller the deviation angle is, the lower the degree of constancy. 5. Regardless of the magnitude of object, the degree of constancy becomes lower in the order of convergence, shape, and size.
