Ch. 4 Topics 3.3-3.4

The visible spectrum of light is

between 400 and 700 nm

Depth perception is possible because of

binocular cues, monocular cues, texture of objects

The place in the retina where the optic nerve exits to the brain is called the

blind spot

Even though it was nearly dark outside, Kaci could still tell that the basketball she was playing with was orange. Which of the following concepts is best illustrated in this example?

Color constancy

Which of the following is an example of shape constancy?

Even though the angle from which she viewed the table had changed, Elise still perceived the table as rectangular.

The ability to see a cube in the gestalt cube above is best explained by which of the following?

Gestalt principles of closure and continuity

A person with sight in only one eye lacks which of the following visual cues for seeing in depth?

Retinal disparity

Which of the following is the correct path a neural impulse will follow through the different layers of the retina?

Rods and cones, bipolar cells, ganglion cells, optic nerve

People who are color blind most likely have deficiencies in their

cones

The eye beds light through the __________, which does the majority of the bending of the light, and the __________, which fine tunes the light.

cornea; lens

The reversible figure above (Rubin's figure) illustrates the Gestalt organizing principle of

figure-ground

Which monocular depth cue is illustrated in the monocular depth illustration?

linear perspective

In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly. This phenomenon occurs because the rods located in the retina are

more sensitive in the dark than cones and are not found in the fovea

If you look at the color green for an extended period of time and then look away, you will see an afterimage of red. Which theory accounts for this phenomenon?

opponent-process theory

The most common form of color blindness is related to deficiencies in the

red-green system

what part of the eye is the light-sensitive surface of the eye, containing photo receptors, onto which visual information is projected?

retina

As you watch a friend walk away from you, your retinal image of your friend gets smaller. Despite this, you do not perceive him to be shrinking. This is an example of

size constancy

What part of the eye is the colored part of the eye that contains muscles that allow the pupil to get larger or smaller depending on how much light is being let into the eye?

the iris

What part of the eye is the nerve that carries neural impulses from the eye to the brain?

the optic nerve

The optic chiasm

transmits visual information from the left side of the retina to the right lobe of the occipital cortex and vice versa.
