Document Summary

Ex: photo receptors in the back of your eye: action potentials then happen after light strikes them. Our senses: sight - vision, hearing audition, taste gustatory, smell olfactory, touch - somatosensory, body awareness proprioception, balance vestibular. Even the receptors you have are lazy and get tired easily. Psychophysics study the links between sensation and perception (cid:862)ato(cid:373)s(cid:863) of e(cid:454)perie(cid:374)(cid:272)e just noticeable difference: what is the change in colour we can make that is only noticeable half the time. Quantifying the perception of change in a given stimulus the law states that the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus. What is the least amount of stimulus we can detect. When a person responds to a lure its called a false alarm if they respond to a target its called a hit.
