Blessing's mother is trying to teach him how to catch a ball. As the ball approaches Blessing, it takes up more and more space on his retinas. Blessing perceives the change in size to mean that the ball is getting closer to him rather than perceiving it to mean the ball is getting larger. Which term does the best job of describing this phenomenon?

Visual expansion refers to the phenomenon where an object approaching us appears to get larger on our retinas, and Blessing perceives this change in size to mean that the ball is getting closer to him. The other options (texture gradient, linear perspective, and motion parallax) refer to different depth cues that aid in depth perception but are not directly related to the perceived size of the ball.
