Unit 4 Review

A person is asked to listen to a series of tones presented in pairs, and asked to say whether the tones in each pair are the same or different in pitch. In this situation the experimenter is most likely measuring the individual's

• attention span

• difference threshold

• sound localization ability

A sound is often detected by one ear more intensely and a fraction of a second earlier than it is detected by the other ear. These cues help individuals determine the

• pitch of the sound wave

• absolute threshold for sound perception

• location of the source

After Sharon stares at a patch of saturated green color for a brief period of time, she looks at a white surface and sees a red patch of color. This perceptual phenomenon is best explained by

• opponent-process theory

• selective attention

• retinal disparity

After staring at a green, black, and orange “American flag” for about a minute, an individual will see a red, white, and blue flag afterimage. Which of the following explains this phenomenon?

• Trichromatic theory

• Color constancy

• Opponent-process theory

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

• auditory localization

• divided attention

• selective attention

Ana injured her eye in an accident and has to wear a patch over the eye while it heals. Which of the following cues would she best be able to use to make judgments about the distance objects are from her?

• Convergence

• Binocular disparity

• Linear perspective

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

• retinal disparity

• continuity

Damage to which of the following best explains conduction deafness?

• Temporal lobe

• Auditory nerve

• Hammer, anvil, and stirrup

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

• less sensitive in the dark than cones and are not found in the fovea

• as sensitive in the dark as cones and are few in number in the fovea

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

In vision, transduction occurs within the

• retina

• visual cortex

• optic nerve
