AP Pyschology unit 3 Flashcards

7748671744	feature detectors	nerve cells in brain, respond to specific features of stimulus shape,angle, or movement	0
7748680745	accommodation	process where eye's lens change shape to focus near or far objects on the retina; focus rays by changing curvature	1

7748733644	pitch	tones experienced highness or lowness; depends on frequency	6
7748738514	audition	the sense or act of hearing	7
7748741191	after images	picture is no longer in front of you, but still see the image	8
7748765620	opponent process theory	opposing retinal processes enable color vision	9
7748770597	color blindness	color deficent; lack functioning red or green sensitive cones	10
7748779683	young- helmholtz trichromatic theory	we have 3 diff types of receptor cells in our eyes; all colors we see are combo of red, blue, and green	11
7748788807	parallel processing	processing of many aspects of a problem simultaneuously color, motion, form,depth	12
7748814732	fovea	retinas area of central focus, around which the eyes cones cluster	13
7748820955	blind spot	optic nerve leaves the eye, no receptor cells	14
7748829484	optic nerve	nerve that carries neural impulse from eye to brain; thalamus stands ready to distribute info	15
7748837414	cones	detect fine details and color sensations, daylight and well lit conditions	16
7748848322	rods	retinal receptors detect black, white and gray; peripheral and twilight vision when cones don't respond; part of retina	17
7748861414	retina	light sensitive inner surface of eye; contains receptor rods and cones	18
7748868343	lens	behind pupil; changes shape to help focus images on retina	19
7748875118	iris	surrounds pupil; controls size; colored portion of eye	20
7748880834	pupil	small adjustable opening in center of eye; light enters	21
7748887317	intensity	amnt. of energy in light or sound waves ( determined by waves amplitude or height); ifluences brightness	22
7748903506	hue	dimension of color; determined by wavelength	23
7748911873	wavelength	distance from peak of one light or sound wave to peak of next; determines its hue	24
7748925908	perceptual constancy	perceiving objects as unchanging even as the retina images change shape, brightness, size, color	25
7748979902	stroboscopic motion	brain perceives movement in a rapid series of slightly varying images; animation	26
7748989087	phi phenomenon	illuson of movement caused by lights flashing in succession	27
7748997121	monocular cues	distance cues that can be processed using only one eye	28
7749006355	retinal disparity	comparing images from retinas in both eyes, brain determines distance; holding fingers in front of face	29
7749028836	perceptual adaptation	visual ability to adjust to artifically displaced visual field	30
7749043405	binocular cues	use both eyes to determine depth	31
7749052753	visual cliff	lab test for testing depth perception in infants	32
7749063091	depth perception	ability to see objects in 3D even though images striking our retinas are 2D	33
7749072825	grouping	tendency to organize stimuli into groups that we understand connectedness, similarity, continuity, closure	34
7749888294	figure ground relationship	organization of visual field into objects (figures); stand out from their surroudings (ground)	35
7749905954	sensorineural hearing loss	damage to cochleas receptor cells; or auditory nerve; once they die won't be replaced	36
7749919715	conduction hearing loss	damage to mechanical system that conducts sound; can be fixed	37
7749925870	gestalt	form, whole; emphazie tendency to intergrate pieces of info into meaning; visual organization; how our mind sees and thinks puts figures together	38
7749945956	perceptual set	mental predisposition to perceive one thing, not another	39
7749956687	sensory adaptation	decline in sensitivity to a constant stimulus; febreeze commercials	40
7749962503	webers law	to be perceived as different; two stimuli must differ by constant minimum percentage	41
7749979067	difference threshold	just noticable difference; minimul difference a person can detect between two stimuli	42
7749985658	priming	predisposing ones perception, memory or response; playing german music in alcohol store more people bought german wine	43
7750001232	subliminal	below absolute threshold; where you detect stimulus in time; hearing test	44
7750010530	frequency theory	rate of nerve impulses traveling up auditory nerve	45
7750024052	place theory	diff. sound waves trigger diff places on cochlea; high freq= near base low= near apex	46
