1. Aim: What are some of the other processes involved in perception?

2. Motion Perception: The Phi Phenomenon:
A series of lights flashed in rapid succession create the illusion of movement

10. Constancies
Shape Constancy: Objects viewed from different angles will produce different shapes on our retinas but we hold the shape of an object constant

12. Brightness Constancy
We perceive objects as being a constant color even as the light reflected off the object changes
