An adequate and an inadequate stimulus, such as light versus pressure on the eyeball, will produce similar experiences because
- A.
They both activate visual receptors and the visual cortex
- B.
The receptors for touch and vision are similar
- C.
Touch and vison receoptors lie side by side in the eye
- D.
Our ability to discriminate is poor
Correct Answer
A. They both activate visual receptors and the visual cortexExplanation
An adequate and an inadequate stimulus, such as light versus pressure on the eyeball, will produce similar experiences because they both activate visual receptors and the visual cortex. This means that even though the stimuli may be different, they still result in the same neural response in the visual system, leading to similar experiences. The receptors for touch and vision being similar or lying side by side in the eye, as well as our ability to discriminate being poor, are not relevant to explaining why the experiences are similar.Rate this question:

- A.
Loudness is to intensity
- B.
Intensity is to loudness
- C.
Stimulus is to response
- D.
Response is to stimulus
Correct Answer
B. Intensity is to loudnessExplanation
Frequency is a measure of the number of cycles of a sound wave that occur in a second, and pitch refers to how high or low a sound is perceived. Similarly, loudness is a measure of the intensity or strength of a sound, and intensity refers to the objective measure of the sound's power. Therefore, the relationship between frequency and pitch is analogous to the relationship between loudness and intensity.Rate this question:

The sequence of sound travel in the inner ear is
- A.
Oval window, ossicles, basilar membrane, eardrum
- B.
Eardrum, ossicles, oval window, basilar membrane
- C.
Eardrum, ossicles, basilar membrane, oval window
- D.
Ossicles, oval window, basilar membrane, eardrum
Correct Answer
B. Eardrum, ossicles, oval window, basilar membraneExplanation
The correct answer is eardrum, ossicles, oval window, basilar membrane. This sequence accurately represents the path of sound travel in the inner ear. Sound waves enter the ear and cause the eardrum to vibrate. The vibrations are then transmitted through the ossicles (small bones in the middle ear) to the oval window. The oval window is a membrane that separates the middle ear from the inner ear. Finally, the vibrations pass through the oval window and reach the basilar membrane, which is located in the cochlea of the inner ear.Rate this question:

Place analysis depends most on the physical characteristics of the
- A.
Hair cells
- B.
Basilar membrane
- C.
Tectorial membrane
- D.
Cochlear canal
Correct Answer
B. Basilar membraneExplanation
Place analysis refers to the process by which the auditory system determines the location of a sound source based on the specific frequency information received by different parts of the cochlea. The basilar membrane is a key structure within the cochlea that plays a crucial role in this process. It is responsible for separating and analyzing different frequencies of sound, with different regions of the basilar membrane responding to different frequencies. Therefore, the physical characteristics of the basilar membrane are most important in determining the location of a sound source in place analysis.Rate this question:

The fact that neurons are limited int heir rate of firing by the refractory period is most damaging to which theory?
- A.
Telephone
- B.
Volley
- C.
Place
- D.
Volley-place
Correct Answer
A. TelepHoneExplanation
The fact that neurons are limited in their rate of firing by the refractory period is most damaging to the telephone theory. The telephone theory suggests that each individual neuron is responsible for transmitting a specific frequency or pitch of sound. However, the refractory period limits the rate at which neurons can fire, making it difficult for each neuron to transmit a specific frequency consistently. This challenges the idea that individual neurons are solely responsible for transmitting specific frequencies, undermining the telephone theory.Rate this question:

The place theory's greatest problem is that
- A.
Neurons cannot fire as frequently as the highest frequency sounds
- B.
Neurons specific for frequencies above 5000 hz have not been found
- C.
The whole basilar membrane vibrates about equally at low frequencies
- D.
Volleying does not follow sound frequency above 5000 hz
Correct Answer
C. The whole basilar membrane vibrates about equally at low frequenciesExplanation
The place theory suggests that different frequencies of sound are processed in different locations along the basilar membrane in the inner ear. However, this theory faces a problem when it comes to low frequencies because the entire basilar membrane vibrates about equally at these frequencies, making it difficult for the brain to determine the specific location of the sound. This is why the whole basilar membrane vibrating equally at low frequencies is the greatest problem for the place theory.Rate this question:

An auditory neuron's tuning curve tells you
- A.
Which frequency it responds to
- B.
Which part of the basilar membran e the neuron comes from
- C.
At what rate the neuron can fine
- D.
How much the neuron responds to different frequencies
Correct Answer
D. How much the neuron responds to different frequenciesExplanation
The tuning curve of an auditory neuron provides information about how much the neuron responds to different frequencies. This means that the curve shows the neuron's sensitivity or responsiveness to different sound frequencies. The curve will typically have a peak or peaks that indicate the frequencies to which the neuron responds most strongly, and the height of the curve at different frequencies represents the magnitude of the neuron's response to those frequencies. Therefore, the tuning curve helps in understanding the neuron's selectivity and sensitivity to different frequencies of sound.Rate this question:

A cochlear implant works because
- A.
The tympanic membrane is intact
- B.
The hair cells are intact
- C.
It stimulates the auditory cortex directly
- D.
It stimulates the auditory neurons
Correct Answer
D. It stimulates the auditory neuronsExplanation
A cochlear implant works by stimulating the auditory neurons. This is because the implant bypasses the damaged or non-functioning hair cells in the cochlea and directly stimulates the auditory neurons. By doing so, it allows individuals with hearing loss to perceive sound and helps them regain their ability to hear.Rate this question:

As a binaural sound location cue, difference in intensity works
- A.
Poorly at low frequencies
- B.
Poorly at medium frequencies
- C.
Poorly at high frequencies
- D.
About equally at all frequencies
Correct Answer
A. Poorly at low frequenciesExplanation
At low frequencies, the wavelength is longer and the sound wave wraps around the head, making it difficult for the brain to detect the difference in intensity between the two ears. This is why the difference in intensity works poorly at low frequencies as a binaural sound location cue.Rate this question:

Mirror neurons' role in language development is supposedly in
- A.
The repetition of word sounds
- B.
Gestural aspects
- C.
Development of grammar
- D.
The use of prosody
Correct Answer
B. Gestural aspectsExplanation
Mirror neurons are specialized cells in the brain that fire both when an individual performs an action and when they observe someone else performing the same action. These neurons are believed to play a crucial role in language development by allowing individuals to imitate and understand the gestures and movements associated with language. This includes not only the repetition of word sounds but also the observation and imitation of gestural aspects such as facial expressions, hand movements, and body language. Therefore, mirror neurons' role in language development is primarily in the processing and imitation of gestural aspects of communication.Rate this question:

- C.
20-20,000Hz
- D.
200-2,000Hz
Correct Answer
C. 20-20,000HzExplanation
The range of human hearing is commonly accepted to be from 20 to 20,000 Hz. This means that the average person can hear sounds that have frequencies as low as 20 Hz and as high as 20,000 Hz. Frequencies below 20 Hz are considered infrasound and are typically felt rather than heard, while frequencies above 20,000 Hz are considered ultrasound and are generally not audible to humans.Rate this question:

- A.
Air
- B.
Water
- C.
Bone
- D.
A and c
- E.
A, b and c
Correct Answer
E. A, b and cExplanation
Sound can be conducted through air, water, and bone. This is because sound waves are mechanical waves that require a medium to travel through. In air, sound waves cause the air particles to vibrate, transmitting the sound. In water, sound waves can travel even faster and more efficiently due to its denser medium. Bone also conducts sound as it is a solid material that can transmit vibrations. Therefore, sound can be conducted through all three mediums mentioned in the answer options.Rate this question:

- B.
200-400 HZ
- C.
2000-4000Hz
- D.
2000-20,000
Correct Answer
C. 2000-4000HzExplanation
Humans are most sensitive to sounds with frequencies in the range of 2000-4000 Hz. This range corresponds to the frequencies at which the human ear is most sensitive and can perceive sounds with greater clarity and detail. Frequencies below this range may be perceived as low or deep sounds, while frequencies above this range may be perceived as high-pitched or shrill sounds. Therefore, the range of 2000-4000 Hz is the most sensitive range for human hearing.Rate this question:

Which of the following causes the eardrum to stretch or relax in response to difference levels of sound?
- A.
Tensor tympani
- B.
Incus
- C.
Pinna
- D.
Tympanic membrane
Correct Answer
A. Tensor tympaniExplanation
The tensor tympani is a muscle in the middle ear that is responsible for stretching or relaxing the eardrum in response to different levels of sound. When the tensor tympani muscle contracts, it tightens the eardrum, reducing its ability to vibrate and dampening the sound. This reflexive action helps protect the delicate structures of the inner ear from loud sounds.Rate this question:

- A.
Outter ear
- B.
Eardrum
- C.
Stapes
- D.
Malleus
Correct Answer
B. EardrumExplanation
The eardrum, also known as the tympanic membrane, is a thin, sensitive membrane located between the outer and middle ear. Its main function is to transmit sound vibrations from the outer ear to the middle ear. It vibrates in response to sound waves, which causes the tiny bones in the middle ear (malleus, incus, and stapes) to amplify the sound and transmit it to the inner ear. Therefore, the eardrum plays a crucial role in the amplification of sound waves in the ear.Rate this question:

Correct Answer
D. Semicircular canalsExplanation
The semicircular canals are not part of the auditory system. They are part of the vestibular system, which is responsible for maintaining balance and spatial orientation. The cochlea, ossicles, and pinna are all structures that are involved in the auditory system. The cochlea is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The ossicles are a group of three small bones (malleus, incus, and stapes) located in the middle ear that transmit sound vibrations from the eardrum to the cochlea. The pinna, also known as the outer ear, helps to collect and funnel sound waves into the ear canal.Rate this question:

Vibrations are initiated in the cochlea by movement of the against the oval window
- A.
Stapes
- B.
Malleus
- C.
Incus
- D.
Helicotrema
Correct Answer
A. StapesExplanation
Vibrations are initiated in the cochlea by movement of the stapes against the oval window. The stapes is one of the three small bones in the middle ear, also known as the ossicles. When sound waves enter the ear, they cause the eardrum to vibrate, which in turn causes the ossicles to move. The stapes, being the last bone in the chain, transfers these vibrations to the oval window, a membrane that separates the middle ear from the inner ear. The movement of the stapes against the oval window creates fluid motion within the cochlea, stimulating the hair cells and ultimately leading to the perception of sound.Rate this question:

Correct Answer
C. Basilar memebranExplanation
Hair cells are sensory cells located in the cochlea of the inner ear, responsible for detecting sound vibrations. They rest on top of the basilar membrane, a thin and flexible membrane that runs the length of the cochlea. When sound waves enter the ear, they cause the basilar membrane to vibrate, which in turn stimulates the hair cells and allows them to convert the mechanical energy of the sound waves into electrical signals that can be interpreted by the brain. The helicotrema is a small opening at the apex of the cochlea, while the tectorial membrane is a gel-like structure that overlies the hair cells. The tympanic membrane, also known as the eardrum, is located at the outer end of the ear canal and separates the outer ear from the middle ear.Rate this question:
