Cards Term visual rabbit Definition sound dominates vision, which is opposite from normal, Term visual range of light Definition 400-700 nm red-higher violet-lower Term iris, cornea, retina, virteous humor, lens, pupil Definition colored, tough first focussing layer, , where the receptors are, the fuid inside, pupil-hole where light passes Term fovea Definition only cones in humans, densest area of receptors Term describe accomodation Definition relaxation of cilliary muscles= lens flattens, allows long distance vision contraction of cillary muscles= lens buches, allows short focusing Term presbyopia Definition requires reading glasses, lens gets less flexible and therefore you cant focus on nearby objects Term myopia Definition elongated eyeball- harder to see far away. nearsighted... Term hyperopia Definition farsighted, flattened eyball Term glaucoma Definition tunnel vision, pressure in eyeball,d amage to optic neve Term cataract Definition lens becomes cloudy Term percentage of cones in humans Definition 5-10 Term rod vision v.s. cone vision Definition nightime b&w v.s. detailed color Term direction of photo reception Definition back of retina forward Term reason for difference between detail v.s. senstivity in rods v.s. cones Definition few cones converge to a few bipolar cells many many rods converget to one, so less info about location and shape. Term steps in photo reception Definition light-->electro chemical reception in receptor--->bipolar--->ganglion--> optic nerve Term opitic nerve path Definition crosses parts of brain at optic chiasm, thalmus (lateral genticulate- then occiptal lobe Term striate cortex Definition appearance of optic lobe Term binocular rivalry Definition the alternation between seeing the patern in the left retina and the patetern in the right retina Term Trichromatic theory (aka) Definition mixing of three receptors, red-long green-medium blue-short creates full spectrum, and they are the only receptors AKA young-helmholtz theory Term opponet-process theory of color Definition relies on pairing of red v green blue v yellow whtie v black, receptors that are excited by one pair, and inhibited by the other. when they get fatigued, they produce the other (after image) Term retinex theory Definition we percieve color throuth comparing differen tpatterns of light, and synthesizes a perception for each area. same oolor can be perceived differnetly because of surrouding impulse Term frequency in sound terms Definition hz, pitch, cycles per second Term amplitude in sound terms Definition dB, loudness Term adult human's hearing range Definition 15-20,000 hz Term praying mantis Definition 25-45 khz Term order of ear bones and name Definition hammer anvil stirrup malus, incus, stapes Term where sound hair cells are, quanity of rows Definition basilar membraine 4 Term frequency principle Definition a action potential per wave -100 hz Term volley Definition 1000-4000 summation of response from four rows Term place principle Definition where the tone vibrates is aidentified as a certain frequency Term cochlea Definition snail containing basilar membrane Term mechanisms of localization Definition echoes for absolute, and pitch, and whic hear hears first Term vestibular sense, major organs (2) Definition semicicrular canals, otolith organs, with calcium carbonate detects acceleration, tilt of head, head movmeent with respect to eyemovment Term receptors of somosensory (4) Definition stetch, pain, skin displacement, bunch of em Term gate theory of pain Definition spinal cord contains areas where, other nervous system imputs from other parts can inhibit or enhance pain Term two pain transmitters Definition substance p, and glutatmate Term natural painrelever Definition endorphins Term capsaicin Definition chemical releases substance p somehow relieves pain Term phantom limb explanation Definition widdowed somasensory cortex makes new connections Term vomeronasal organ Definition pheromones, menstrual cycle synchrony may be a consequence Term number of and names of type of taste buds Definition sweet, sour, salty, bitter, umami Term "major" function of taste Definition to regulate eating Term absolute sensory threshold Definition intensity of stimulus that a given individual can detect 50% of the time Term signal detection theory Definition study of reporting stimulus in minmal situations, changes based on motivation Term subliminal perception Definition stimulus can effect our behavior even when its not percieved conciously, small confirmation in studies, nothing huge Term brightness contrast Definition is the increase or decrease in an opbjects brightness becaus eof objects around it Term feature detectors Definition specialized neurons that respond to specific features such as line ansd angles, applies to motion as well Term gestalt psychology Definition the study of perception as the recogonitioon of paterns, reversible figures demonstrate that we put tgoether complex paterns of imput Term proximity Definition grouping by of close images Term similarity Definition the grouping of similar objects Term continuation Definition a filling in of the gaps Term closure Definition filling in the gaps Term common fate Definition we assume its one object if it moves as one Term good figure Definition assumption that figures are normal regular, similar to the expectations slide Term similarity between hearing and sight perception 2 Definition reversible images, closure/continuation Term stroboscopic moevement Definition movies videos, lots of similar pictures Term induced movmeent Definition any apparent movment not real Term convergence retinal disparity these are e.g. of ? Definition cordinated turning in of eyees to see close objects the different images as seen as the left and right retinas binolcular cues Term relative size accomodation elevation superposition linear perspective areal prospective shadows texture gradients Definition high horizon line things in front block convergence on a point of lines, slanting in areal- blueing of distance, diffraction by dust thigns close have more detail Term motion parralax Definition depth while moving, things close= blury
