The finding that otoacoustic emissions are modulated by selective attention suggests that
A)the effects of auditory selective attention are limited to the cerebral cortex.
B)the effects of visual selective attention are limited to the cerebral cortex.
C)the mechanical properties of the vocal tract may change in response to attentional control.
D)the mechanical properties of the cochlea may change in response to attentional control.

Question

Quizplus · Accepted Answer

Otoacoustic emissions are sounds generated by the inner ear in response to sound stimuli. The finding that otoacoustic emissions are modulated by selective attention suggests that attentional control influences the mechanical properties of the cochlea, which is responsible for generating otoacoustic emissions. Therefore, the correct choice is D. Choice A and B are incorrect because the effects of selective attention can be observed in various brain regions beyond the cerebral cortex. Choice C is not relevant to the finding about otoacoustic emissions.
