What is the place theories main assumption?
The place along the basilar membrane that vibrates the most, determines what pitch is percieved
It is the place in the cochlea, either the vestibular canal, tympanic canal or scala media, which vibrates most that determines what pitch is percieved
The place in auditory space in which the sound is conceived determines what pitch is percieved
The place along the sound wave that reaches the ear first determines what pitch is percieved
Name three areas of evidence for place theory: (a), (b) and (c).
(a) Observations of the travelling wave (b) Stimulated deafness experiments (c) Frequency-specific hearing loss

Three pieces of evidence against Place Theory: (a), (b) and (c)
(a) Insufficient explanation for complex sounds (b) The missing fundamental (c) Ability to perceive pitch from broadband stimuli
FOR MORE INFORMATION PLEASE SEE NOTES
(a) The missing fundamental (b) Not all frequencies have been found to have a "place" on the basilar membrane (c) Ability to perceive pitch from broadband stimuli
What is the main assumption of Temporal (Frequency) Theory?
The rate of vibration of the stimulus determines the perceived pitch
The frequency that is most prominent in an auditory stimulus determines the perceived pitch
Higher frequencies are associated with an increased perception of pitch and decreased frequencies are associated with a lower pitch perception
More frequently heard stimuli are perceived more clearly in terms of their pitch
What is one critique (a) and one counter (b) to Temporal Theory?
(a) Refractory Period (b) Volley Principle
(a) Volley Principle (b) Refractory Period
(a) Broadband Stimuli (b) Stimulated-Deafness
(a) Stimulated-Deafness (b) Broadband Stimuli
