Psycholinguistics Final Flashcards
perceptual invariance (lack of invariance):
Sounds that are acoustically variable are perceived as the same sound.
coarticulation
Sounds are affected by neighbouring sounds
phoneme, allophone
phonemes are distinct categories, chair vs couch, allophones are the same category, different kinds of chairs.
Categorical perception
clear shift in phonemes; sharp boundaries imposed by mental categories; the difference is perceived at a threshold. Humans can only identify sounds categorically. Stronger effects for consonants over vowels. (sounds)
Continuous perception
a gradual change along the VOT continuum, where one and more listeners start hearing one sound over another at different times, however people are only agreeing at the two ends of the spectrum. (words)
ie) peach vs. beach
forced-choice identification task
listen to a sound, is it /pa/ or /ba/.
ABX discrimination task
listen to sound X, is it more like A or B?
McGurk effect
bottom-up processing): there is mismatch in the sounds we hear vs see. Our interpretation of speech sounds depends on acoustic signals and visual signals.
Ganong effect
(top-down processing): uses words and non-words; did you hear /k/ or /g/? We know that /kift/ is not a real word so we hear /gift/.
phoneme restoration effect
Even if we miss a sound in a word, we will fill it in because we know the intended word.
Top-down
prior knowledge helps listeners identify speech sounds
Motor Theory
knowledge of how sounds are produced affects speech perception; you need to know how articulators move.
semantic priming
You retrieve the desired word, but also partially activate related words; which makes them easier to access later (spreading of activation)
lexical decision task (LDT)
participants have to decide if a word is real or not; based on speed. Faster to recognize a real word if it follows a semantically related word.
Masked priming paradigm
Lexical decision task (have to decide if a word is real or not)
Less time between prime and target words
visual world eye-tracking experiment
they locate the target but also look at semantically related words and cohort competitors.
Experimental stimuli
the stimuli that is measured
Control stimuli
an unrelated word, just to throw the participant off track
facilitation effect
easier to recognize a word when it appears after a semantically related one
inhibition effect
Partially activated words “get in the way”, Phonologically related words like [stiff] vs. [still]
neighbourhood density effect
it will take longer to recognize words with dense phonological neighbours
cross-modal priming task
both meanings are accessed at first (ie of bug), but several syllables later, the appropriate meaning is selected and the irrelevant meaning is thrown away
decay
activation levels will decrease over time and activation depends on time.
cohort competitors
Share same initial sound
cohort model
lexical activation starts right after the beginning of a word, and multiple cohort competitors are active
TRACE model
Words that overlap anywhere with the target word all get activated
direct route
memorize a series of units that you identify as a word.
Assembled phonology route
graphemes (written symbols) are sounded out, starting at the left edge of the word. More skilled = direct route used.
