1. Relative size. Since the car looks so small in the picture, we can tell it is far away. 2. Linear perspective. We perceived the line as parallel even if it seems to converge. 3. Familiar size. Unlike picture 1, we can tell car 1 is closer due to the size of the object (car). 4. Shadows. We can tell the white guy is walking first by comparing his shadow to the other guys’ shadows.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
