speech percept 2 Flashcards
T or F: acoustic cues are sequential
false
T or F: noise obscures acoustic cues
true
T or F: a single acoustic cue reliably defines a phonemic category
false
diff between auditory vs motor speech perception theories?
- auditory: listener uses aud system to identify patterns/features and match them to learned acoustic-phonetic language features.
- motor: link bw speech perception + production (extracting artic info from signal to overcome variability)
problems w quantal theory/acoustic invariance theory? (3)
- vocal tract structures interact
- different articulators are controlled with different degrees of precision
- hearing system responds differently to different frequencies
what is “universal speech module”? which theory is it part of?
- theory that humans have biological endowment for language
- part of motor theory
supports for motor theory? (4)
- categorical perception in speech
- duplex perception
- mcgurk effect
- mirror neurons
how was motor theory disproved?
- chinchillas were able to discriminate human speech
is categorical perception applicable only to speech?
no
what is cohort theory?
- proposes that word recognition / processing starts as soon as we hear first phoneme
- bottom-up in early stages and top-down in later stages
what is the TRACE model?
- 3 layers: feature, phoneme, lexical (word)
- connections bw levels are bidirectional
- connections within levels = competition
T or F: speech perception follows general physics and physiology of sensory perception
true
what are the 6 sources of listener bias we discussed?
- selective attention
- categorical speech perception
- phonemic restoration
- multi-sensory integration
- priming effects
- word recognition effects
T or F: we can consciously pause the mcgurk effect
false
from the hairy ankle study, syllables heard simultaneously with cutaneous air puffs were more likely to be heard as aspirated (for example, ______).
/b/ heard as /p/
