Psych module 17

The ability to accurately perceive distances MOST clearly underlies one's capacity for

Size constancy

lens

The lens is the transparent structure behind the pupil that changes shape to focus light rays on the retina.

occipital lobe

The occipital lobe receives information from the visual fields.

According to the Gestalt psychologists, people tend to fill in the gaps to create a complete, whole object. This is called the principle of _____.

Closure

Denise wears an extremely bright safety yellow sweatshirt when she cycles to the gym after dark. The sweatshirt's brightness reflects the _____ of the light it reflects.

High amplitude

With respect to the trichromatic and opponent-process theories of color perception, which statement is MOST accurate?

Trichromatic theory describes color processing early in the visual system; opponent-process theory describes color processing later on in the visual system.

Do Feature-detecting neurons receive information from specific ganglion cells?

Yes

Feature-detecting neurons are located in the visual cortex.

Yes

Feature-detecting neurons process information about the shape, angle, or movement collected from a visual scene.

Yes

Talia is 45 years old. She has started to notice that newspaper print is too small for her to read. Talia needs reading glasses because the lenses of her eyes are less able to adjust, or _____.

accommodate

A door casts an increasingly trapezoidal image on one's retinas as it opens, yet one still perceives it as rectangular. This illustrates shape _____.

constancy

Which choice links a visual function with the correct pair of eye structures?

focusing light—cornea and lens

As one walks into a brightly lit room, the black structure in the center of one's eye seems to shrink to a tiny black dot. This response is caused by the action of the eye structure called the:

iris

Talia is 45 years old. She has started to notice that newspaper print is too small for her to read. Talia needs reading glasses because the:

lenses of her eyes are less able to accommodate.

Relative _____ refers to the amount of light an object reflects relative to its surroundings.

luminance

cornea

protects the eye and bends light to provide focus

Jess was in a serious car accident and is having trouble recognizing familiar faces. She MOST likely suffered damage to her _____ lobe, just behind her right ear.

temporal lobe

fovea

the central focal point in the retina, around which the eye's cones cluster

extrasensory perception

the controversial claim that perception can occur apart from sensory input; includes telepathy, clairvoyance, and precognition

opponent-process theory

the theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green

Violet is to red as _____ is to _____.

400 nm; 700 nm

White paper reflects _____ percent of the light falling on it, while black paper reflects _____ percent.

90:10
