Document Summary

Barnett newman, voice of fire, 1967. (courtesy national gallery of canada, ottawa, canada) Sensation part 1: general principles & audition. Psy1101 b,c,d: introduction to psychology: foundations | dr. k. campbell. How are sensation and perception different: sensation -- sensory input and transmission, transduction (at the level of the receptor). Sensitive to only a very limited range of the earth"s energy. As an example, the ear is sensitive to energy in the form of air pressure. The role of the sensory receptor is to transduce a very restricted amount of the earth"s energy (that required for the survival of the species) into something the nervous system can understand, an electrical signal. The ear translates one form of energy (air pressure) into an electrical signal that then travels along the auditory nerve as an action potential. The eye translates light energy into an electrical signal that travels along the optic nerve.
