Document Summary
Psychophysics: the study of how physical simuli are translated into psychological experience. Sensaion: detecion of physical energy by the sense organs. 5 senses: sight (visual), hearing (auditory), taste (gustatory); smell (olfactory); touch (tacile) Transducion: (going from outside the world to within) the process of convering an external simulus into electrical signals within neurons (or a language the nervous system understands) Ater being transduced, our brains then organize the sensory data into meaningful concepts. Sensory adaptaion: acivaion is the grates when the simulus us irst detected (ie. we sit on a chair and then no longer noice we are siing on a chair) Percepion: the brain"s interpretaion of raw sensory data, so what you perceive (ie the depth of the color screen makes it appear as a rose) The study of how we perceive sensory simuli based on their physical characterisics. But what counts as detectable depends on whom or what is doing the detecing.
