Document Summary

Module 4: sensation and perception (4. 1) sensation and perception at a glance. Sensation process of detecting external events by sense organs and turning them into neural signals. Perception involves attending to, organizing, and interpreting stimuli that we sense. Sensory receptors structures that respond to external stimuli. Transduction process in which physical or chemical stimulation is converted into nerve impulse that is relayed to the brain. Sensory adaptation reduction of activity in sensory receptors with repeated exposure to a stimulus. Hair cells that respond to pressure change in the ear. Different types of nerve endings that respond to pressure, temp changes, and pain. Nerve endings that respond selectively to different compounds. Steps of sensation to perception: stimulus -> sensory receptors -> (transduction) -> neural. Psychophysics field of study that explores how physical energy such as light and sound and their intensity related to psychological experience.
