AP Psychology FAQ 3.2- Vision and Audition

Dilation and constriction of the pupil are controlled by the

• optic nerve.

• lens.

• retina.

• iris.

• cornea.

Objects are brought into focus on the retina by changes in the curvature and thickness of the

• rods and cones.

• lens.

• bipolar cells.

• optic nerve.

• cornea.

Humans experience the longest visible electromagnetic waves as

• the color blue-violet and the shortest visible waves as red.

• the color red and the shortest visible waves as green.

• the color blue and the shortest visible waves as yellow.

• the color red and the shortest visible waves as blue-violet.

• the color black and the shortest visible waves as white.c

The amplitude of electromagnetic waves determines the ________ of light.

• absolute threshold

• brightness

• hue

• difference threshold

• wavelength

The pitch of a sound is determined by what?

• the frequency of the sound wave

• the amplitude of the sound wave

• the loudness of the sound wave

• the decibel level of the sound wave

• the vestibular level of the sound wave

The rupture of the eardrum can lead to

• sensorineural hearing loss.

• disruption of the vestibular system.

• feeling disembodied.

• conduction hearing loss.

• change deafness.

The coiled, fluid-filled tube in which sound waves trigger nerve impulses is called the

• eustachian tube.

• auditory canal.

• semicircular canal.

• cochlea.

• vestibular apparatus.

What is the purpose of the eardrum?

• Vibration of the eardrum directly causes ripples in the basilar membrane.

• Axons on the eardrum converge to form the auditory nerve, which sends auditory messages to the brain.

• Transduction of sound waves into neural messages occurs in the eardrum.

• Movement of the eardrum directly causes the stirrup to vibrate.

• To transmit sound from the air to the bones of the middle ear.

When looking at the hands of a clock showing 8 o'clock, certain brain cells in the visual cortex are more responsive than when the hands show 10 o'clock. This is most indicative of

• sensory interaction.

• feature detection.

• parallel processing.

• perceptual adaptation.

• accommodation.

The ability to simultaneously recognize the color, shape, size, and speed of an oncoming automobile best illustrates

• sensory interaction.

• kinesthesis.

• parallel processing.

• subliminal perception.

• blindsight.
