Unit 3 Lesson Review

Which of the following supports the opponent-process theory of color vision?

Afterimages

Which of the following is true regarding visual information processing?

Bipolar cells relay information to ganglion cells that form the optic nerve.

Which of the following refers to the photoreceptors responsible for color vision?

Cones

Kaori is traveling on an airplane for the first time. As the plane takes off, she watches the automobiles driving on the freeway below. Even though the automobiles seem to get smaller as the airplane gains altitude, Kaori does not perceive the cars as shrinking but still perceives them to be their normal size. Which perceptual principle best describes this phenomenon?

Constancy

Ernie comes in from outdoors on a bright, sunny day and finds it to be very dark inside. Over the next few minutes, however, it becomes easier for Ernie to see inside. The perceptual process this scenario is describing is

Dark Adaption

If Carmelita stares at a red spot for one minute and then shifts her gaze to a white piece of paper, she is likely to experience an afterimage that is

Green

Feature detectors are neurons that are turned on or off by specific features of visual stimuli like edges and movement. Where in the visual system are these feature detectors located?

Occipital Cortex

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

Red-Green System

In vision, transduction occurs within the

Retina

corresponds to the light-sensitive surface of the eye that contains photoreceptors?

Retina

Ana is instructed by her doctor to wear a patch over one eye while an infection heals. While wearing the patch, Ana will lose her ability to use which of the following depth perception cues?

Retinal Desparity

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

The change in the curvature of the lens that enables the eye to focus on objects at various distances is called

accommodation

Visual acuity is best in the

fovea

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

Negative afterimages are explained by

opponent-process theory

An individual's ability to focus on a particular conversation in a noisy and crowded room is called

selective attention

A reason that one typically does not notice a blind spot in the visual field is that

the brain fills in missing information so there is no awareness that the visual field is incomplete

The fovea has the greatest visual acuity in bright light primarily because the fovea is

made up of cones only
