Question

______ constancy refers to the ability to understand that an object retains the same form even when viewed from a different angle.

○ structural
○ shape
○ brightness
○ color

Explanation:

Shape constancy is the perceptual phenomenon where we perceive an object's shape as constant even when its retinal image changes due to different viewing angles. Structural constancy is not a standard term for this concept. Brightness constancy relates to perceived brightness despite light changes, and color constancy relates to color perception despite lighting changes. So the correct option is Shape.

Answer:

B. Shape
