PSYC1011 Study Guide - Final Guide: Naked Mole-Rat, Electromagnetic Spectrum, Stim
Document Summary
Perception: em energy travels in wavelengths, human eye detects 400 to 700 nm (visible light) What is perception: key aspect of our existence, organisation & interpretation of sensory info from world. Inferring the physical quantity that generated the sensation based on sensory signals: almost any comm of info involves perceptual processes. Is the reception & transmission of info about physical aspects of the world: process by which sense organs gather info about envir transmit to brain for initial processing, our interface w/ the world. ** no true distinction b/t p & s all aspects of sys are sculpted to enable perception. Flow chart: absolute thresholds, minimum amount of physical energy to detect a stimulus, 2 distinct processes to detect: I(cid:374)terpretatio(cid:374) depe(cid:374)ds o(cid:374) (cid:271)oth se(cid:374)siti(cid:448)it(cid:455) & o(cid:271)ser(cid:448)ers (cid:272)riterio(cid:374) for id a se(cid:374)satio(cid:374) as (cid:858)sig(cid:374)al(cid:859) Indiv tries to distinguish meaningful from irrelevant stimulation: changing stimulation, change in stim must be large enough to detect change.
