Auditory processing

Recognizing a melody is an example of...

• Top-down processing

• Bottom-up processing

• Middle-out processing

• Phonemic processing

Which of these ear parts is NOT located in the middle ear?

• Stirrup

• Ossicles

• Anvil

• Auditory canal

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

• organ of corti

• auditory canal.

• semicircular canal.

• cochlea.

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.

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.

The mechanical vibrations triggered by sound waves are transduced into neural impulses by

• hair cells.

• the eardrum.

• the oval window.

• the auditory cortex.

The pitch of a sound is based on the _____ of its waves.

• timbre

• purity

• amplitude

• frequency

A researcher studying the location of neural activity in the cochlea finds that hair cells nearest the oval window vibrate more to high-frequency sounds. This supports the ________ theory of pitch perception.

• place

• frequency

• Gestalt

• vibration

Where is the basilar membrane located?

• middle ear

• auditory canal

• semicircular canal

• cochlea
