Document Summary

Computational model approach to perception focuses on how computations by the nervous system translate raw sensory stimulation into an experience of reality. I(cid:374) short: (cid:374)er(cid:448)ous syste(cid:373)"s (cid:373)a(cid:374)ipulatio(cid:374)s of i(cid:374)(cid:272)o(cid:373)i(cid:374)g sig(cid:374)als. Constructivist approach approach to perception taken by those who argue that the perceptual system uses fragments of sensory info to construct an image of reality. In short: emphasizes inferences we make about environment. Ecological approach approach to perception maintaining that humans and other species are so well adapted to their environment that many aspects of the world are perceived without requiring higher-level analysis and inferences. Psychophysics focuses on relationship b/w physical characteristics of environmental stimuli and our psychological experiences of those stimuli. Absolute threshold smallest amount of light, sound, pressure or other physical energy we can detect 50% of the time: subliminal stimulation stimulation too weak or brief to be perceived.
