Shape Constancy describes the tendency to perceive what as the same despite changes in viewing angle?

• A. Shape remains the same
• B. Size remains the same
• C. Distance remains the same
• D. Color remains the same

Answer: (A)

Shape constancy is the perceptual tendency to treat an object's shape as unchanged even when the viewing angle changes the silhouette or outline on the retina. This is why you still perceive a circle as circular or a square as square even when you’re looking at it from an angle—the brain uses surrounding cues and prior knowledge to interpret the geometry and keep the shape constant. So the correct idea is that the shape remains the same despite perspective shifts. Color remaining the same is about color constancy (staying constant under different lighting), size remaining the same is about size constancy (keeping perceived size constant despite distance changes), and distance perception involves depth cues rather than the object’s shape staying constant.
