Psychology Chapter 5.3

cones

light detecting cells

cornea; pupil

light waves are transmitted across the ___ and enter through the ___

depth perception

our ability to perceive spatial relationship in 3D space

linear perspective

refers to the fact that we perceive depth when we see two parallel lines that seem to converge in an image

binocular cues

rely on the use of both eyes

retina

rods are located where?

binocular disparity

slightly different view of the world that each of our eyes receives

fovea

small indentation in the back of the eye where the lens focuses images on

rods

specialized photoreceptors that work well in low light conditions; lack the spatial resolution and color function; involved in vision in dimly lit environments and perception of movement

cones

specialized types of photoreceptors that work best in bright light conditions; very sensitive to acute detail and provide tremendous spatial resolution; involved in ability to perceive color

photoreceptor cells; cones

the fovea contains densely packed specialized ___ which are called __

retina

the light sensitive lining of the eye

optic chiasm

the optic nerve from each eye merges just below the brain at what?

pupil

the small opening in the eye through which light passes and the size of it can change as a function of light levels and well as emotional arousal

cornea

the transparent covering over the eye; serves a barrier between the inner eye and the outside world; involved in focusing light waves that enter the eye

optic nerve

carries visual info from the retina to the brain

iris

controls the size of the pupil; colored part of the eye

monocular cues

cues that require only one eye

lens

curved, transparent structure that serves to provide additional focus; attached to muscles that can change its shape to aid in focusing light that is reflected from near or far objects

blind spot

a point in the visual field we are not aware of bc each eye gets a slightly different view of the visual field and our visual system fills in the blind spot

lens

after passing through the pupil, light crosses the ___

retina

fovea is part of the ___
