Quote: sound is but the motion of the clapper carried to us by the bell, air, ear, nerve, brain, and outward nerves [»hobbT_1650, OK]

Quote: the things that really are in the world without us, are those motions by which these seemings are caused

Quote: any three differently colored lights whatsoever can always be mixed to produce any color whatsoever; may need to take one light from the other [»feynRP_1963]

Quote: brown light is a dark red and yellow mixture against a lighter background [»feynRP_1963]

Quote: sound is the vibration of the air moving the cartilages of the tympanum; waves are rapidly propagated from trembling bodies; frequent waves have high pitch, rare waves low pitch [»galiG_1623]

Quote: words, voice, and sound are made of atoms; a shout makes the windpipe rough; noise and voice strike the sense when they crawl in the ear [»lucr_55]

Quote: animals use different sounds in different situations; man's vocal range can distinguish all the different things he found [»lucr_55]

Quote: to many animals, smell defines the existence and nature of a thing [»kentW_1978]

Quote: taste and smell determined by the size, shape, quantity, and speed of minute particles; either fall to the tongue or rise to the nose [»galiG_1623]

Quote: the sense of taste is flavours squeezed out of food onto the tongue [»lucr_55]

Quote: motion is the cause of heat; fire is a multitude of minute particles, having a shape and velocity, that pentrate the body [»galiG_1623]

Quote: beyond four, quantities are vague; must count to find out [»ifraG_2000]

Quote: eyes register light at the atomic limit of one light quantum; other organs may have similar capabilities [»bohrN8_1932]

Quote: when light strikes strongly absorbing organic substances (e.g., rhodopsin), all electrons shift by one double bond; effectively moving an electron the width of the molecule [»feynRP_1963]

Quote: 5 or 6 photons will activate an eye's nerve cell; if a single photon, would see flashes of equal intensity, i.e., particles [»feynRP_1985]

Quote: an icon is a temporary record of sensory input that lasts 1/4 second; e.g., movies and holding words across eye fixations [»sowaJF_1984]

Quote: hearing and touch also rely on percepts and icons (8 seconds and 20 seconds resp.); none for olfaction [»sowaJF_1984]

Quote: the human eye is slightly sensitive to light polarization; can learn to tell the direction of the sun by rotating your head about the axis of vision [»feynRP_1963]

Quote: it is impossible to turn both eyes out at the same time because the eye's muscles are controlled together [»feynRP_1963]

Quote: ambient visual channel optimized for locomotion information; like peripheral vision

Quote: study color vision by understanding the participation of the visual system in generating a color space; not by mapping the colorful world on the visual system [»matuHR_1980]

Quote: an object's geometry effected the visual system, and the visual system used geometric relations to specify color distinctions; but the geometries did not match [»matuHR_1980]

Quote: the phoneme may be the consequence of perception instead of an intermediate form [»dreyHL_1979]

Quote: tastes, odors, colors are mere names as far material objects are concerned; they are only excitations of living animals; same as tickling and armpits

Quote: perceptual schemas to represent environment, motor schemas for motor control; plus coordinated-control program [»arbiMA_1987]

Quote: a visual schema is a pattern of percepts from previous experience that are used to build models for interpreting new experience [»sowaJF_1984]

Quote: motor system is responsive to the visual framework, e.g., moving the walls around an infant causes a fall [»trevC_1984]

Quote: need a theory how perceiving keeps an animal in contact with reality for the successful conduct of its actions [»turvMT_1984]

Quote: perception should be viewed as the specification of an external reality; not as a grasping of that reality; like hallucination [»matuHR_1980]

Quote: in the frog vision papers, assumed that the frog perceived an external reality; e.g., feature detectors [»matuHR_1980]

Quote: Maturna, et. al. demonstrated that the visual system responded to patterns of local variations, e.g., dark spots; not direct representation [»winoT_1986]

Quote: both movements and perceptions of an organism are determined topologically; e.g., drawing a star [»bernN_1935]

Quote: perceptual recognition and motor reproduction is sensitive to spatial orientation; e.g., drawing or recognizing upside down figures [»bernN_1935]

Quote: regard as real those sense perceptions which are common to different individuals and hence impersonal; e.g., rigid bodies [»einsA_1956, OK]

Quote: familiarity is the source of much of the organization and order of conscious experience; even for an elephant in your room [»searJR_1992]

Quote: there exist regularities over perceptual categories that are not stateable over stimulatory categories [»pylyZW_1986]

Quote: there may be no restrictions on how stimulation is compatible with some perceptual interpretation

Quote: though no two people perceive reality the same, views overlap enough to allow cooperative work [»kentW_1978]

Quote: perception is organized into objects and features, not undifferentiated shapes; consciousness is of something as such and such [»searJR_1992]

Quote: our universe is not chaos; we perceive and name beings and objects that have stable structures [»thomR_1975]

Quote: understanding a concept and seeing an object are similar processes; both are through intermediaries such as retinas and linguistic expressions [»churA_1951]

Quote: before the discovery of chromosomes, they did not appear in published drawings of cell nuclei [»sowaJF_1984]

Quote: no categorical perception for fluent ASL signers; sharp crossovers in labeling, yet can discriminate similar stimuli in the same category [»newpEL_1982]

Quote: since things change, they are perceived by mind alone; self perception is the clearest of all [»descR_1641]

Quote: if the environment is only known through brain states, how can it be known objectively and accurately? [»turvMT_1984]

Quote: Descartes' doctrine of Corporeal Ideas--all awareness's are awareness's of states of the body

Quote: the Cartesian program seeks to impose subjective, meaningful categories on an objective, meaningless surround

Quote: perception--the nervous system generates phenomena rather than acting as a filter on reality; like hallucination [»winoT_1986]

Quote: the brain searches percepts for ones that match parts of a new sensory icon [»sowaJF_1984]

Quote: the brain needs to compare the differences between perception and representations of internally controlled elements [»bernN_1957]

Quote: consonant sounds have harmonics of the same frequency

Quote: notes sound dissonant if their upper harmonics have frequencies near enough to cause a rapid beat [»feynRP_1963]

Quote: Mozart saw all of piece at a single glance, like a beautiful painting; heard all at once [»sowaJF_1984]

Quote: a mirror image reverses front and back, not right and left; e.g., top and bottom not reversed [»bateG_1979]

Quote: the Compendium is a manual Hypertext of reference data on human perception and performance; 3000 pages text and 2000 figures, tables, illustrations [»glusRJ5_1989]
