Question 7
Question
What is the structure of the ear that transduces sound vibrations into nerve impulses?
Answer
-
oval window
-
temporal lobe
-
cochlea
-
stirrup
Question 8
Question
Jefferson has had years of exposure to high-amplitude sound through his work as a helicopter mechanic. Lately he has noticed that he is losing his ability to detect high-frequency sounds. What has Jefferson most likely damaged?
Answer
-
his eardrum
-
the tiny bones of his middle ear
-
his cochlea
-
his auditory canal
Question 9
Question
Which structure of the ear serves a similar function as the retina serves in the eye?
Answer
-
pinna
-
eardrum
-
cochlea
-
ossicles
Question 10
Question
What are the direct receptors for hearing?
Answer
-
hair cells
-
basilar cells
-
ossicles
-
cochleas
Question 11
Question
What process allows us to hear pitch, according to place theory?
Answer
-
There is differential movement of specific ossicles.
-
The entire cochlea vibrates at a speed equivalent to the wavelengths that stimulate the ear.
-
Vibrations occur at specific locations on the basilar membrane.
-
Specific hair cells are simultaneously stimulated all along the length of the semicircular canals.
Question 12
Question
Imagine that the basilar membrane in the human ear were longer. What might you expect humans to be able to do, based on place theory?
Answer
-
localize sounds more accurately
-
hear more sounds of lower frequency, but lose some higher frequency sounds
-
hear a wider range of sounds
-
detect sound waves that had a lower amplitude
Question 13
Question
Which theory of hearing views the basilar membrane as being like a drumhead?
Answer
-
place
-
timpani
-
opponent process
-
frequency
Question 14
Question
The maximum firing rate for individual neurons is 1,000 neural impulses per second. What does this biological limitation mean for theories of perception?
Answer
-
Trichromatic theory cannot fully explain colour perception.
-
Opponent process theory cannot fully explain colour perception.
-
Place theory cannot fully explain pitch perception.
-
Frequency theory cannot fully explain pitch perception.
Question 15
Question
What is the major flaw in the frequency theory of pitch perception?
Answer
-
It places the transduction process in the semicircular canals and not the cochlea.
-
Structurally, it is impossible for the basilar membrane to vibrate.
-
The action of the ossicles interacting with the auditory nerve was misidentified.
-
Neurons cannot fire fast enough to account for hearing tones higher than 1,000 cycles/second.
Question 16
Question
Which theory, or theories, best explain(s) pitch perception for very low-pitch, very high-pitch, and middle-pitch sounds, respectively?
Answer
-
place theory; both theories; frequency theory
-
place theory; frequency theory; place theory
-
frequency theory; place theory; both theories
-
frequency theory; both theories; place theory
Question 17
Question
After reading the Featured Study, in which of the following might you enroll your child if you wanted to enhance
your child’s ability to interpret speech prosody?
Answer
-
team sport rather than an individual sport
-
linguistics course
-
visual arts course
-
keyboard lessons
