Shape constancy states that objects viewed from different angles will produce different shapes on our retinas, but we know that the shape of the object remains constant; this is the case for A-Rod. The final contributor to how vision affected his perception would be that we perceive objects as being a constant color even as the light reflecting off the object changes.  A-Rod may be used to playing ball at night which changes the color of the ball and so when daytime came around, the ball itself was a foreign object to him. As day comes the ball will look more vibrant. But we know that the color is always white or black even though it may not look like so in our retina.

In this case, A-Rod’s eyes could have perceived the ball to be farther away than it truly was, resulting in it hitting his knee. As an object comes closer to us, our ...
