AP Psych, Module 18 Flashcards

8063506612	Wavelength	The distance from the peak of one light or sound wave to the next peak.	0
8063506613	Hue	The dimension of color that is determined by the wavelength of light.	1
8063506614	Intensity	The more energy, the more intensity a wave has. More intensity = brighter color.	2
8063506615	Pupil	The adjustable opening in the center of the eye through which light enters.	3
8063506616	Iris	A Ring of muscle tissue that forms the colors portion of the eye around the pupil. Also controls the size of the pupil opening.	4
8063506617	Lens	The transparent structure behind the pupil that changes shape to help focus images on the retina	5
8063506618	Retina	Light sensitive inner surface of the eye, containing receptor rods and cones along with layers of neurons that begin the process of visual information	6
8063506619	Accomadation	The process by which the eye's lens changes shape to focus near or far objects on the retina	7
8063506620	Rods	Retinal receptors able to detect black, white and gray; used for peripheral and twilight vision when cones don't respond	8
8063506621	Cones	Retinal receptor cells concentrated near the center of the retina and that function in well lit conditions. They detect fine detail and give rise to color sensations	9
8063506622	Optic Nerve	The nerve that carries neural impulses from the eye to the brain.	10
8063506623	Blind Spot	The point at which the optic nerve leaves the eye, creating a blind spot because no receptor cells are located there.	11
8063506624	Fovea	The central focal point in the retina where cones are heavily concentrated	12
8063506625	Feature Detectors	Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement	13
8063506626	Parallel Processing	The processing of several aspects of a problem simultaneously; the brain's natural mode of information processing for many functions, including vision.	14
8063506627	Young-Helmholtz Trichromatic Theory	the retina contains three different color receptors - one most sensitive to red, one to green, one to blue - which, when stimulated in combination, can produce the perception of any color.	15
8063506628	Opponent Process Theory	The theory that opposing retinal processes enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green white-black red-green yellow-blue	16
