Question

14. Blake and Sekuler describe Zatorre, Belin & Penhune's (2002) explanation of how humans manage to have both good frequency resolution and good temporal resolution. Which of the following represents that account? a. The superior olive analyzes frequency differences, and the inferior colliculus analyzes temporal differences. b. The inner hair cells mediate frequency differences, and the outer hair cells mediate temporal differences. c. The cochlea analyzes frequency differences, and the semicircular canals analyze temporal differences. d. The left hemisphere is specialized for frequency analysis, while the right hemisphere is specialized for temporal analysis. e. none of the above is true

Explanation / Answer

The correct answer is C. Cochlea analyzes frequency differences and semicircular canal analyzes temporal differences.

Sound is transmitted to tge fluids,pressure wave activates or deforms the basilar membrane and that too in area specific for frequency of vibration.

Cochlea can analyse sound difference between the frequency of 20Hz and 20000 Hz.

Temporal canal contains receptors and canals for inner ear for hearing and equilibrium systems.Hence,it can sense temporal differences.

Temporal resolution means capacity of ear to sense the occurence of two consecutive sounds and that too avoiding it sensing as a single event.
