PSYCH 2E03 Lecture 1: Topic 1 - What is Sensory Perception
Document Summary
Transduction - transformation of sensory (environmental signals) into electrical neural impulses by sensory receptors. Stimulus > receptor process > neural processing > perception > recognition > Neural process: receptor cell > subcortical brain areas > cortical brain areas (primary receiving area) > other cortical areas (speci c) * neural processing occurs at the all levels (receptor, sub/cortical)! ** this process isn"t de nite > it ows back and forth between cortical levels. (multidirectional arrows) Stimuli, and responses created by stimuli are changed between environmental stimuli and perception of the stimuli. Categorize - based on our prototypes and categories. Action - send signals to muscles to react to stimuli. Sensation: capture information from physical world and transform them into biological impulses. Perception: a single uni ed awareness of a stimulus that arises from the sensation produced by our sensory systems. ** each species have different sensory abilities to promote survival! *** sensation and perception are not the same thing.
