  1. sound with a sinusoid waveform (when pressure change is plotted against time)
    pure tones
  2. the perceived property of sounds that enables them to be ordered from low to high
    pitch
  3. the perceived intensity of the sound
    loudness
  4. the lowest frequency component of a complex sound that determines the perceived pitch
    fundamental frequency
  5. if the fundamental frequency of a complex sound is removed, then the pitch is not perceived to change (the brain reinstates it)
    missing fundamental phenomenon
  6. the perceptual quality of a sound enables us to distinguish between different musical instruments
    timbre
  7. part of the inner ear that converts liquid borne sound into neural impulses
    cochlea
  8. a membrane within the cochlea containing tiny hair cells linked to neural receptors
    basilar membrane
  9. the main cortical area to receive auditory based thalamic input
    primary auditory cortex
  10. orderly mapping between sound frequency and position on cortex
    tonotopic organization
  11. the division of a complex auditory signal into different sources or auditory objects
    auditory stream segregation
  12. an ERP component that occurs when an auditory stimulus deviates from previously presented auditory stimuli
    mismatch negativity (MMN)
  13. an auditory agnosia in which music perception is affected more than the perception of other sounds
    amusia
  14. a developmental difficulty in perceiving pitch relationships
    tone deafness (congenital amusia)
  15. patterns of pitch over time
    melody
  16. type of auditory agnosia in which patients are able to identify environmental sounds and music but not speech
    pure word deafness
  17. plots the frequency of sound (on the y-axis) over time (on the x-axis) with the intensity of the sound represented by how dark it is
    spectrogram
  18. different spoken acoustic renditions of the same phoneme
    allophones
  19. horizontal stripes on the spectrogram produced with a relative free flow of air (eg by vowels)
    formants
  20. vibration of the vocal chords that characterizes the production of some consonants
    voicing
  21. continuous changes in input are mapped on to discrete percepts
    categorical perception
  22. the production of one phoneme is influences by the preceding and proceeding phonemes
    co-articulation
  23. an auditory percept derived from a fusion of mismatching heard speech and seen speech
    McGurk Illusion
  24. a short term memory store for verbal material that is refreshed by subvocal articulation
    articulatory loop
  25. an inability to repeat non-words and the production of semantic errors in word repetition
    deep dysphasia
