AP Vision/Hearing

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

• dichotic listening ability

• sound localization ability

• difference threshold

• echoic memory

• attention span

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

• retinal disparity

• linear perspective

• motion parallax

• relative size

• texture gradient

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

• the blind spot is very small and no visual stimuli are likely to be so small that the blind spot completely obscures them

• most visual stimuli affect only one visual hemisphere and one hemisphere can cover for the other

• visual stimuli usually affect the occipital cortex in both hemispheres

• the blind spot habituates to a stimulus when the head is held still

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

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

• timbre of the sound wave

• absolute threshold for sound perception

• frequency of the sound wave

• 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

• retinal disparity

• opponent-process theory

• color constancy

• selective attention

• trichromatic theory

After spending hours in her kitchen preparing dinner, Rebecca no longer notices the strong smell of garlic until her guests arrive and mention the smell. Her failure to notice the smell of garlic illustrates

• anosmia

• synethesia

• sensory adaptation

• subliminal perception

• the just-noticeable difference

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

• opponent-process theory

• retinex theory

• color constancy

• convergence

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

• auditory localization

• dichotic listening

• deep processing

• 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

• similarity

• closure

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

• motion parallax

• retinal disparity

• size constancy

• continuity

• common fate
