Depth perception refers to our ability to perceive objects and understand their distance relative to us. It helps us determine how far or near an object is from our viewpoint.
Visual illusions are deceptive images or perceptions that trick our brain into perceiving something differently than reality. They can play a role in how we interpret size and distance.
Size Constancy: Size constancy is the tendency for us to perceive objects as maintaining their actual size despite changes in their distance from us. It allows us to recognize that even though an object appears smaller when farther away, it remains the same size.
