This course will provide you with an introduction to the psychology, neuroscience, and philosophy of visual perception. We will explore how we see. People tend to think, naively, that there is not much to opening our eyes and seeing. Our eye is not a camera and there is a huge amount of complicated processing going on (most, if not all of it, unconsciously), and it is these processes, which have been discovered through empirical investigation, that we will look at. Expect this course to make you question the nature of what is real and what is illusion, and cause you to wonder how we can ever be sure of the difference.
