The discovery that high-frequency sounds trigger large vibrations near the beginning of the basilar membrane supports the ________ theory.

A) gate-control
B) frequency
C) dissociation
D) place

The discovery of large vibrations near the beginning of the basilar membrane in response to high-frequency sounds supports the Place theory, which posits that different frequencies of sound waves stimulate different locations on the basilar membrane, leading to the perception of different pitches. The gate-control theory suggests that pain signals are controlled by gates in the spinal cord, dissociation theory pertains to psychological coping mechanisms, and frequency theory proposes that the frequency of sound waves is directly related to the firing rate of auditory neurons.
