cognition chapter 10 key terms

sound with a sinusoid waveform (when pressure change is plotted against time)

the perceived property of sounds that enables them to be ordered from low to high

the perceived intensity of the sound

the lowest frequency component of a complex sound that determines the perceived pitch

if the fundamental frequency of a complex sound is removed, then the pitch is not perceived to change (the brain reinstates it)

the perceptual quality of a sound enables us to distinguish between different musical instruments

part of the inner ear that converts liquid borne sound into neural impulses

a membrane within the cochlea containing tiny hair cells linked to neural receptors

the main cortical area to receive auditory based thalamic input

orderly mapping between sound frequency and position on cortex

the division of a complex auditory signal into different sources or auditory objects

an ERP component that occurs when an auditory stimulus deviates from previously presented auditory stimuli

an auditory agnosia in which music perception is affected more than the perception of other sounds

a developmental difficulty in perceiving pitch relationships

patterns of pitch over time

type of auditory agnosia in which patients are able to identify environmental sounds and music but not speech

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

different spoken acoustic renditions of the same phoneme

horizontal stripes on the spectrogram produced with a relative free flow of air (eg by vowels)

vibration of the vocal chords that characterizes the production of some consonants

continuous changes in input are mapped on to discrete percepts

the production of one phoneme is influences by the preceding and proceeding phonemes

an auditory percept derived from a fusion of mismatching heard speech and seen speech

a short term memory store for verbal material that is refreshed by subvocal articulation

an inability to repeat non-words and the production of semantic errors in word repetition
