PSYA01H3 Chapter Notes - Chapter 5: Sclera, Computer Monitor, Aqueous Humour
Document Summary
In this chapter we will be focusing on our input systems , the senses we use to perceive the world around us. We will focus primarily on vision, but will also discuss audition, touch and smell. Much of the information will attempt to explain how these systems work though we will also discuss illusions that show us how our sensory systems can be tricked. Throughout, we will again emphasize the distinction between sensation, the information arriving through the sense organs,and perception, the subjective impression of the world that we end up with. The textbook actually defines sensation and perception slightly differently from how i have, though the flavor is the same. Sensation is the detection of simple stimulus properties such as brightness, colour, sound frequency, sweetness. Perception is the detection of objects, their location, their movements, their background. Thus, seeing purple and blue in the picture is sensation, whereas seeing beautiful fireworks is perception.
