weeks 8.2 to 10.2 Flashcards
language-specific phonology
features (e.g., voicing, aspiration) that can contrast meanings
categorical perception
we tend to perceive “categories” in language; can vary with one’s language background; members/exemplars with subtle differences within the category likely to be perceived as the same; often tested on a continuum of synthesized stimuli; can be language-specific
the typical way of designing a categorical perception experiment (3)
(1) identify two sounds that differ in an acoustic feature and that native listeners can discriminate; (2) create a continuum that starts from one sound to another by varying the key acoustic feature, can consist of 20 or more stimuli/”steps”; (3) ask participants to identify each stimulus along the continuum
“indexical properties of speech”
speaker-related characteristics; the feature of the sounds you use to identify the speakers
McGurk effect
mismatch between auditory and visual information, which change the sound you hear
motor theory of speech perception
perceive the intended articulatory gestures; evaluate the gestures needed for the sounds perceived
AX discrimination vs ABX categorization task
AX: determine if two sounds/syllables/nonwords are the same
ABX: determine if the third stimulus (X) is more similar to the first (A) or second (B)
gating task
a paradigm for studying spoken word recognition; words presented segment by segment incrementally (each gate = current + previous segment)
isolation point of recognition (IP) (gating task)
the point (in ms) when a word is recognized
cohort
a collection of possible words to be activated/selected; serial processing of speech; this model can be tested using a gating paradigm
implications of Grosjean (1980) (3)
high frequency words recognized faster than low-frequency ones; semantic context helps word recognition; serial processing of speech sounds
possible recognition processes (routes in VWR) (3)
(1) visual input –> orthography –> phonology –> semantics (e.g. form-based; Chinese characters)
(2) visual input –> phonology –> orthography –> semantics (e.g. sound-based; English)
(3) visual input –> orthography –> semantics –> (phonology)
alphabetic vs. logographic writing systems
alphabetic: more transparent mapping/correspondence from form to sound
logographic: more transparent mapping/correspondence from form to meaning
grapheme
a letter, letter strings, characteristics, etc.
consistent vs. inconsistent GPC (“grapheme-phoneme correspondence”)
consistent: (nearly) one-to-one mapping, shallow orthography (one grapheme to one sound)
inconsistent: one-to-many mapping, deep orthography (one grapheme to many sounds)
