Question

12. Which statement best describes place theory? a. We hear different pitches because the bones of the middle ear are different sizes. We hear different pitches because different wavelengths cause different hair cells ?ilia) to be stimulated along the basilar membrane. c. We hear different pitches because the neural firing rate matches the sound frequency d. We hear different pitches because the semicircular canals and Eustachian tubes resonate to low and high wave frequencies, respectively e. We hear different pitches because different wave frequencies stimulate different parts of the tympanic membrane. 13. Why do scientists believe color vision is universal across cultures? People across the world have the same names for spectral colors. People across the world arrange colors in the same sequence. c. People across the world show preference for short-wavelength colors d. People across the world associate colors with meanings similarly. e. People across the world have the same color preferences

Explanation / Answer

The place theory describes that the perception of sound by our auditory sense depends on the pitch which stimulates the basilar membrane producing sound waves at different rates. We hear different pitches because different wavelengths cause hair cells along the basilar membrane activated.

Thus, the correct answer is option, B.

Color vision is universal across cultures because people around the world arrange colors in the same sequence. They have different names to colors. Names are not universal. However, the sequence in which color is arranged is the same across cultures.

Thus, the correct answer is option B.
