AP PSYCHOLOGY

Detailed explanation-1: -Place theory is a theory of hearing that states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane.

Detailed explanation-2: -The place theory of pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies. More specifically, the base of the basilar membrane responds best to high frequencies and the tip of the basilar membrane responds best to low frequencies.

Detailed explanation-3: -According to the frequency theory, the: basilar membrane vibrates in synchrony with a sound, producing action potentials at the same frequency.

Detailed explanation-4: -Most psychologists agree that hearing sound stimuli at low frequencies is accounted to the frequency theory, whereas those at high frequencies are attributed to the place principle. Sound stimuli in mid frequencies are believed to be rightfully accounted to both hearing theories.

Detailed explanation-5: -This is called ‘place theory’ as it is the place of activity on the basilar membrane, or the place of activity in the nerve array, that represents the frequencies that are present in the sounds.
