Resumen del Recurso

Pregunta 1

Pregunta
What is the place theories main assumption?
Respuesta
  • 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

Pregunta 2

Pregunta
Name three areas of evidence for place theory: (a), (b) and (c).
Respuesta
  • (a) Observations of the travelling wave (b) Stimulated deafness experiments (c) Frequency-specific hearing loss
  • FOR MORE INFORMATION READ THE HAND-WRITTEN NOTES
  • (a) Comparisons of basilar membrane between humans and dogs (b) Stimulated deafness experiments (c) Experiments on deaf people

Pregunta 3

Pregunta
Three pieces of evidence against Place Theory: (a), (b) and (c)
Respuesta
  • (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

Pregunta 4

Pregunta
What is the main assumption of Temporal (Frequency) Theory?
Respuesta
  • 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

Pregunta 5

Pregunta
What is one critique (a) and one counter (b) to Temporal Theory?
Respuesta
  • (a) Refractory Period (b) Volley Principle
  • (a) Volley Principle (b) Refractory Period
  • (a) Broadband Stimuli (b) Stimulated-Deafness
  • (a) Stimulated-Deafness (b) Broadband Stimuli

Pregunta 6

Pregunta
Name a support for Temporal Theory
Respuesta
  • The Missing Fundamental
  • Stimulated-Deafness Experiments
  • Amplitude Research
