Section 1

(39 cards)

Frequency

Front

difference between peaks. determines what color you see

Back

Optic Chiasm

Front

optic nerves from the inside half of each eye cross over and then to the opp. side of the brain

Back

Feature Detectors

Front

neurons that respond selectively to very specific features of more complex stimuli

Back

Cornea

Front

clear curved structure that light must pass through first

Back

Secondary Pathway

Front

10%. leaves optic chiasm branches to superior colliculus

Back

Amplitude

Front

vary in height. determine intensity of the light

Back

Subtractive Mixtures

Front

removes wavelengths, leaving less light than was originally there

Back

Light Adaptation

Front

becoming less sensitive to light

Back

Additive Mixtures

Front

different wavelengths of light are directly mixed together. superimposes light

Back

Receptive Fields

Front

Collection of rods and cones that funnel signals through Bi-Polar cells to the Ganglion cells. Smaller =more ganglion cells=more accuracy

Back

Pupil

Front

opening in the center of iris that lets light enter inside.

Back

Main Pathway

Front

90% of vision. into Thalamus and LGN, then to occipital lobe

Back

Where (who) Pathway

Front

(parietal area). where objects are located (ex. visual neglect)

Back

Lateral Geniculate Nucleus (LGN)

Front

A place in the thalamus that receives impulses from the optic nerve and sends information to the occipital lobe. Part of the main pathway.

Back

Rods

Front

peripheral vision, night vision

Back

Color Blindness

Front

When a person loses a red, green, or blue receptor that does not allow for proper additive mixing of colors of light.

Back

What Pathway

Front

(temporal area) helps with recognition of objects like faces (ex: visual cognition)

Back

Opponent Processing Theory

Front

color perception depends on receptors that make antagonistic responses to 3 pairs of colors (yellow/blue, red/green, black/white)

Back

True

Front

True of False: It takes cones 10 minutes to acclimate to a suddenly bright environment.

Back

Parallel Processing

Front

the processing of many aspects simultaneously

Back

Dark Adaptation

Front

getting used to seeing things at night

Back

Optic Nerve

Front

Connects with ganglion cells to transmit optical inputs to the brain.

Back

Stroop Test

Front

color of text different from what it says. left and right brain disagreeing

Back

True

Front

True or False: Rods take 30 minutes to adjust to suddenly dark light conditions. (Night vision).

Back

Superior Colliculus

Front

coordination of visual input with other sensory input (visual reflexes)

Back

Lateral Inhibition/Antagonism

Front

occurs when neural activity in a cell opposes activity in surrounding cells

Back

Bi-Polar Cells

Front

Nerve cells that transmit perception of light from rods and cones and send to ganglion cells.

Back

Retina

Front

neural tissue that aligns back surface of the eye

Back

Hubel and Wiesel

Front

Names of the two psychologists who discovered feature detectors while experimenting on different visual environments for anesthetized cats.

Back

Fovea

Front

area at the center of the retina that is predominantly cones

Back

Occipital Lobe

Front

A region of the cerebral cortex that processes visual information

Back

Iris

Front

muscle that controls the opening of the pupil

Back

Lens

Front

transparent eye structure that focuses light rays falling on the retina

Back

Cones

Front

daylight vision, color vision

Back

Trichromatic Theory of Color VIsion

Front

the theory that there are three kinds of cones in the retina, each of which responds primarily to a specific range of wavelengths (red, green, blue)

Back

Optic Disk

Front

The "blind spot" of the eye where the optic nerve connects with the retina.

Back

Ganglion Cells

Front

receive the message from the Bi-Polar cells and transmit these messages to the brain.

Back

Light

Front

formed by electromagnetic radiation that travels as a wave

Back

Iris

Front

Muscle around the eye that controls the quantity of light that enters the eye.
