Sounds of different frequencies activate different areas of the basilar membrane,a fact critical for the _____ account of auditory perception.
A)signal detection
B)temporal code
C)threshold
D)place code

Question

Quizplus · Accepted Answer

The statement refers to the fact that different frequencies activate different areas of the basilar membrane. This is part of the place code theory of auditory perception, which states that the brain identifies the frequency of a sound based on the location of its maximum vibration along the basilar membrane. This is in contrast to the temporal code theory, which suggests that the brain identifies the frequency of a sound based on the timing of neural firing in response to the sound. Choice A (signal detection) and C (threshold) are not relevant to the explanation given.
