Deck 5: Sound, Speech, and Music Perception

Question 1

Which of the following best describes how brain imaging has shaped our understanding of speech perception?

A) Neuroimaging has confirmed the theories of the 19^th century without requiring revisions.
B) To date, neuroimaging techniques have not been used to examine the 19^th century theories on speech perception.
C) Neuroimaging has confirmed the general aspects of speech perception models from the 19^th century, though specific details continue to be discovered.
D) Neuroimaging has revealed critical flaws in previous theories of speech perception, resulting in the development of an entirely new model.

Answer 1

C

Question 2

The primary auditory cortex is located

A) In the anterior cingulate region
B) At the posterior half of the Sylvian fissure
C) At the corpus callosum
D) Within Heschl's gyrus

Answer 2

D

Question 3

Which of the following responses best reflects the findings by Portas and colleagues regarding auditory awareness during sleep?

A) Beeps but not names activated the auditory cortex when the subject was sleeping, indicating that the auditory cortex processes only some types of sounds during sleep
B) Names activated the auditory cortex when the subject was awake but not when the subject was sleeping, indicating that the auditory cortex does not process names during sleep
C) Beeps and names activated the auditory cortex both when the subject was awake and when the subject was sleeping, indicating that the auditory cortex processes sounds even during sleep
D) Beeps and names activated the auditory cortex when the subject was awake but not when the subject was sleeping, indicating that the auditory cortex does not process sounds during sleep.

Answer 3

Beeps and names activated the auditory cortex both when the subject was awake and when the subject was sleeping, indicating that the auditory cortex processes sounds even during sleep

Question 4

The rate at which a sound pressure wave vibrates is terms of cycles per second hertz, Hz) is known as the ________ of the sound.

A) Frequency
B) Amplitude
C) Pitch
D) Period

Question 5

Neuroimaging has revealed that primary auditory cortex area A1) is active

A) While we are perceiving a sound but not while imagining a sound
B) While imagining a sound but not while perceiving a sound
C) During both perceiving and reproducing a sound
D) During both imagining and pretending to sing a sound

Question 6

Interaural level differences are differences between , contributing to the process of sound localization.

A) The time delay in a sound as it reaches each ear
B) The intensity of a single sound as it reaches each separate ear
C) The height of a sound as it reaches each ear
D) The directions of a sound as it reaches each ear

Question 7

The ? pathway is an efferent pathway while the pathway is an afferent pathway.

A) Ascending, descending
B) Descending, ascending
C) Dorsal, ventral
D) Ventral, dorsal

Question 8

The time scale for distinguishing between the spoken consonants "b" and "d" is ; however, distinguishing between intonation patterns in sentences requires about .

C) 200 ms, 2000 ms
D) 2000 ms, 20 ms

Question 9

Briefly explain the differences between the 'where' and 'what' auditory systems.
The auditory system must keep track of many aspects of the complex auditory scene: where sounds are occurring in space and when sounds occur are they simultaneous, or does one sound precede another?) to determine what the sound represents in terms of known auditory objects, such as speech or music or new auditory objects to be learned.

Question 10

Music fills us with emotion. What neural pathways enable this?

A) Auditory pathway and a visual processing stream
B) Auditory-limbic pathway and an acoustically activated vestibular pathway
C) Limbic pathway and a subcortical visual pathway
D) Auditory pathway and the somatic-brainstem pathway

Question 11

What are the basic physical features and psychological aspects of sound?

Question 12

Two psychological dimensions of sound are

A) Frequency and loudness
B) Pitch and amplitude
C) Frequency and amplitude
D) Loudness and pitch
