Document Summary

Sensaion: process in which sensory receptors and nervous system receive and represent simulus energies from our environment. Percepion: process of organizing and interpreing sensory informaion and enabling us to recognize meaningful objects and events. Botom-up processing: analysis beginning with sensory receptors, works up with brain"s integraion of sensory informaion. Top-down processing: informaion processing guided by higher-level mental processes, constructs percepions drawing on experience and expectaions. Selecive atenion: focusing of conscious awareness on a paricular simulus. Cocktail party efect: ability to atend to only one voice among many. In-atenional blindness: failing to see visible objects when atenion is elsewhere. Change blindness: failing to noice changes in the environment. Change deafness: fail to noice change in speaking. Pop out: we don"t choose to atend to simuli, they draw our atenion. Psychophysics: study of relaionships between physical characterisics of simuli, intensity, and our psychological experience of them. How long our eyes focus on certain points.
