Document Summary

Sensation = simple stimulation of a sense organ. Perception = the organization, identification, and interpretation of a sensation in order to. The basic registration of light, sound, pressure, odor or taste form a mental representation. Occurs after a sensation registers in your central nervous system. Takes place at the level of your brain. Sensation and perception are separate events but related. Transduction = when many sensors in the body convert physical signals from the environment into encoded neural signals sent to the central nervous system. The structuralists led by wundt and titchener tried using introspection to measure perceptual experiences. 2 ppl may describe a sunset in the same words like beautiful and orange, but neither can directly perceive the other"s experience of the sunset. Gustav fechner developed a new approach to measure sensation and perception called psychophysics : methods that measure the strength of a stimulus and the observer"s sensitivity to that stimulus.
