PSY 102 Chapter Notes - Chapter 4: Stretch Receptor, Opponent Process, Comfort Food
Document Summary
Sensation first allows us to pick up the signals in our environments, & perception than allows us to. Illusion: the way you perceive the stimulus doesn"t match its physical reality. Sensation: detection of physical energy by sense organs (eyes, ears, skin, nose, & tongue), which then send information to the brain. Perception: the brains interpretation of raw sensory inputs assemble these signals into something meaningful. Two sides of the coin: sensation & perception. Our brain picks & chooses among the types of sensory information it uses, often relying on expectation & prior experiences to fill the gaps & simplify processing. Transduction: process by which the nervous system converts an external stimulus, like light or sound into electrical signals within neutrons. Sense receptor: specialized cell responsible for converting external stimuli into neutral activity for a specific sensory system. Sensory adaptation: activation is greatest when a stimulus is first detected.
