In the context of AP Psychology, which of the following best defines the frequency theory of hearing?
A
The frequency theory states that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, enabling us to sense its pitch.
B
The frequency theory claims that the intensity of a sound is determined by the amplitude of the sound wave.
C
The frequency theory suggests that different areas of the cochlea are activated by different frequencies, allowing us to perceive pitch.
D
The frequency theory proposes that sound localization is determined by the time difference in which sound waves reach each ear.

Step 1: Understand that the frequency theory of hearing is a concept in auditory perception explaining how we perceive pitch.
Step 2: Recognize that the frequency theory states the rate at which nerve impulses travel up the auditory nerve corresponds to the frequency of the sound wave.
Step 3: Note that this means the auditory nerve fires action potentials at the same frequency as the sound wave, allowing the brain to interpret pitch based on this firing rate.
Step 4: Differentiate this from other theories, such as the place theory, which involves different areas of the cochlea responding to different frequencies.
Step 5: Conclude that the frequency theory specifically links the frequency of the sound wave to the rate of neural impulses, which is how pitch is sensed according to this theory.
