Question 1

Individual nerve cells increase the frequency of neural impulses in the auditory nerve by firing in rapid succession.This is said to illustrate

Accepted Answer

The description given relates to the volley principle, which describes how individual neurons can work together to increase the rate of neural impulses sent to the brain, allowing for accurate perception of sounds. The other options (A, B, and D) do not relate to this specific process.

Question 2

Mr.Wilkes has difficulty hearing sounds in the range of 20 to 40 decibels,but he has no difficulty hearing sounds above that range.He would most likely profit from today's digital hearing aids because they can deliver sound that is

Accepted Answer

Mr. Wilkes has difficulty hearing sounds in the range of 20 to 40 decibels. Digital hearing aids can compress sounds in this range, making them louder and easier for Mr. Wilkes to hear, while also amplifying sounds above this range. Therefore, he would most likely profit from a digital hearing aid that can deliver compressed sound.

Question 3

Damage to the hammer,anvil,and stirrup is most likely to cause

Accepted Answer

Damage to the hammer, anvil, and stirrup would disrupt the conduction of sound waves through the middle ear to the inner ear, resulting in conduction hearing loss.

Question 4

Place theory suggests that

Accepted Answer

Place theory suggests that the pitch we hear is related to the place where the cochlea's basilar membrane is stimulated. Specifically, different frequencies of sound waves cause different parts of the basilar membrane to vibrate, which in turn triggers neurons to fire and send signals to the brain that are interpreted as different pitches.

Question 5

The volley principle is most directly relevant to our perception of

Accepted Answer

The volley principle refers to how groups of neurons work together to fire in rapid succession, allowing us to perceive higher frequencies of sound, such as pitch. Therefore, the volley principle is most directly relevant to our perception of pitch, making choice D the correct answer.

Question 6

Some combination of place theory and frequency theory appears to be most necessary in accounting for how we sense

Accepted Answer

Place theory best explains how we perceive high-frequency sounds, while frequency theory is more applicable to low-frequency sounds. For intermediate-frequency sounds, a combination of both theories is necessary to account for how we sense these sounds.

Question 7

After a small section of his basilar membrane was damaged,Jason experienced a noticeable loss of hearing for high-pitched sounds only.Jason's hearing loss is best explained by the ________ theory.

Accepted Answer

The loss of hearing for high-pitched sounds only suggests that only a specific section of the basilar membrane was damaged. According to the place theory, different areas along the basilar membrane respond to different sound frequencies, so damage to a specific section would result in a loss of hearing for the corresponding frequency range.

Question 8

Infant rats deprived of their mothers' grooming touch produce

Accepted Answer

Infant rats deprived of their mothers' grooming touch produce less growth hormone and have a lower metabolic rate. Studies have shown that maternal grooming touch plays a crucial role in the regulation of growth hormone secretion and metabolic activities in rats. Rats deprived of such touch show stunted growth and decreased metabolic activity.

Question 9

A time lag between left and right auditory stimulation is important for accurately

Accepted Answer

A time lag between left and right auditory stimulation is important for accurately locating sounds. This is because sound waves arrive at the left and right ears at slightly different times, and the brain uses this time difference to determine the direction of the sound source.

Question 10

The greatest number of hair cells lining the basilar membrane are activated in response to ________ sound waves.

Accepted Answer

High-amplitude sound waves produce louder sounds, which activate a greater number of hair cells on the basilar membrane due to the increased movement of the membrane.

Question 11

Premature human babies gain weight faster if they are stimulated by

Accepted Answer

Studies have shown that premature human babies gain weight faster if they receive "gentle touch" in the form of hand massage. This stimulation can also lead to better neurological development and improved sleep patterns. Blinking lights and rhythmic sounds may be overstimulating for premature babies, and phantom limb sensations are not relevant.

Question 12

A cochlear implant converts sounds into

Accepted Answer

A cochlear implant converts sounds into electrical signals that are sent to the brain to be interpreted as sound.

Question 13

The sense of touch includes the four basic sensations of

Accepted Answer

The sense of touch includes the four basic sensations of pressure, pain, warmth, and cold. Pleasure and wetness are not considered basic sensations of touch. Hot is a type of warmth sensation, not a separate sensation.

Question 14

The barn owl's right ear opens slightly upward while its left ear opens slightly downward.This difference enables the owl to detect the ________ of a sound.

Accepted Answer

The difference in the directionality of the owl's ears allows it to detect the location or direction from which a sound is coming. This is useful for hunting as it allows the owl to detect the precise location of prey, even in complete darkness.

Question 15

Cocking your head would be most useful for detecting the ________ of a sound.

Accepted Answer

Cocking your head helps to detect the location of a sound by allowing your ears to process the sound from different angles and determine which ear is receiving the sound more strongly, indicating the direction it is coming from. Pitch, loudness, and amplitude do not require cocking of the head to detect.

Question 16

Place theory was first proposed by

Accepted Answer

Place theory was first proposed by Georg von Békésy in 1928, who received the Nobel Prize in Physiology or Medicine in 1961 for his research on the functioning of the cochlea. Ronald Melzack is known for his contribution to the gate control theory of pain, Ernest Hilgard for hypnosis research, and Harry McGurk for his demonstration of the McGurk effect.

Question 17

Ringing of the ears after exposure to loud music is most likely to be caused by damage to

Accepted Answer

Ringing in the ears, also known as tinnitus, after exposure to loud music is typically caused by damage to the hair cells within the cochlea, which are responsible for converting sound vibrations into electrical signals that the brain can interpret. Nociceptors are pain receptors and would not be involved in this process. Cochlear implants are devices that can help people with hearing loss, but they are not related to the ringing sensation. Bipolar cells are involved in transmitting visual information from the retina to the brain and are not related to hearing.

Question 18

Many hard-of-hearing people like sound compressed because they remain sensitive to ________ sounds.

Accepted Answer

The answer of Many hard-of-hearing people like sound compressed because...

Question 19

According to place theory,the perception of

Accepted Answer

According to place theory, different frequencies of sound waves stimulate different locations on the basilar membrane, with high-pitched sounds stimulating the region closest to the oval window and low-pitched sounds stimulating the region further away from the oval window. Therefore, the perception of high-pitched sounds is associated with large vibrations of the basilar membrane closest to the oval window.

Question 20

Which of the following best explains how we perceive very low-pitched sounds?

Accepted Answer

Frequency theory suggests that for low-pitched sounds, the frequency of the sound wave directly corresponds to the rate of firing of neural impulses in the auditory nerve.
