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 ___
