Frage 1
Frage
What is the place theories main assumption?
Antworten
-
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

Frage 3
Frage
Three pieces of evidence against Place Theory: (a), (b) and (c)
Antworten
-
(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
Frage 4
Frage
What is the main assumption of Temporal (Frequency) Theory?
Antworten
-
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
