Document Summary

Lecture 1 sensation and perception: overview: processes involved in perception, transduction. Transduction means changing energy from one form to another. We have electrical pulses that send information- travelling up and down our nerves. Vision (light energy- form of electromagnetic radiation) electrical system. Light comes off an object called a distal stimulation. Things that are black don"t reflect much light into the eye as opposed to white. Light is being shown onto the back of the eye (the retina). The proximal stimulation is on the back of the eye- this is what we respond to (not the distal stimulation). Occurs when molecules hit against one another. When hitting a blackboard, the molecules of the hand hit the one of the blackboard and the air. The sound molecules hit those in your ear, which are sloshed around fluid in the inner ear, and there are neurons weighed back and forth: interpretation. Interpretation the act or process of explain the meaning of something.
