Document Summary

Sensation: awareness resulting from the stimulation of a sense organ. Psychophysics/biophysics: effects of physical stimuli on sensory perceptions and mental states. Transduction: conversion of stimuli to electrical impulses, then transported to brain via neurons. Top-down processing: whole > sum of parts, gestalt philosophy. Optical illusions: gestalt information is throwing us off, our (cid:373)i(cid:374)d ca(cid:374)"t correctly deduce o(cid:374) co(cid:374)clusio(cid:374, too much information to process if correctly. Interposition: one object overlaps with another we view it as closer: light and shadow: eye receives more reflective light from objects closer to us. Sensation & perception: hearing loss, conductive hearing loss- physical damage to parts of the ear, sensorineural hearing loss- damage to the auditory nerve, prolonged loud noise = cilia damage, as we age, we lose cilia. Taste: 6 taste sensations on our tongue, sweet, salty, sour, bitter, spicy and savory, taste buds = 2000-10,000, as we age, replacement goes down.
