AP PSYCHOLOGY

Detailed explanation-1: -For very high frequencies, pitch is coded according to place of vibration on the basilar membrane; for lower pitches, the rate of neural activity in the auditory nerve matches the sound’s frequency. The frequency theory of hearing is better than place theory at explaining our sensation of: the lowest pitches.

Detailed explanation-2: -the frequency theory is the most comprehensive in explaining pitch perception. the place theory best explains how we hear different pitches.

Detailed explanation-3: -Place theory states that the location on the basilar membrane activated during sound sensation corresponds to the pitch of the sound perceived. Frequency theory states that the speed at which the neural impulse travels through the auditory nerve corresponds to the pitch.

Detailed explanation-4: -Place theory is accurate, except that receptive cells along the inner membrane lack independence in response. They vibrate together as suggested by the frequency theory. Sound waves travel along the membrane, peaking at a given region depending on the frequency.

Detailed explanation-5: -Frequency theory: The rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone; enabling us to sense its pitch. Best explains how we sense low pitches. Place theory: links the pitch we hear with the place where the cochlea’s membrane is stimulated. Best explains how we sense high pitches.
