Speech Perception Flashcards
(27 cards)
Recognize own name by __months; common words by ___ months. This also means that around __m they’ll look longer at a hand than a foot if you say “hand”. Bilinguals pass these milestones at the same rate/ faster than monolingual
4, 6, 6
same rate
pre-natal babies particularily hearing the ___ properties of sound before birth
rythmic
what did the preferential paradigm with babies 2-7m reveal about speech vs non-speech
at all ages the babies looked longer at speech than non-speech
t/f even newborn babies a day old will suck longer to speech than non-speech
true
for english-Filipino Bilingual Newborns Mothers spoke both English and Tagalog (at least 30-70%) during pregnancy, what did they show in sucking paradigms after they were born
they can distinguish between the languages, but sucked about equally to both. didnt have a preference
what method was used to find out the newborn brain responds better to forwards speech than backwards
fnirs (light)
for english newborns, what preferences for forward/backward speech did they show for English and Spanish? oxygen levels?
English newborns showed greater activation for FW vs BW English speech, but equally strong activation to both FW and BW for Spanish
generally higher oxygen levels in RH and LH when shown the english speech
in terms of forward/backward speech what was shown when english monolinguals were shown spanish vs whistle languages
english babies still showed a preference for spanish forward. able to recognise oh this is an actual language
english newborns and 3 month infants were tested by hearing monkey sounds vs human sounds. what were the findinds
- at birth babies were just as happy to hear the monkey calls but at 3 months they prefered english speech
tested babies at 6m and 10m to see if they prefer sign or pantomine. what were findings
hearing infants 6m-preference for ASL. but at 10m they show no preference
evidence showing preference for a linguistic stimuli at birth!!
t/f infants prefer their own n vocalizations over those of other infants
t
phonetic discrimination is __-like in infants. explain why
categorical
able to distinguish /pa/ and /ba/ better if you give them 2 different labels, as opposed to 2 sounds that have the same amount of phonemic variation but they’re both labelled /pa/
talk about babies abilities to distinguish native/non-native distinctions, ages important (english vs hindi)
young english babies are good at discriminating it then drop off around 10m, whereas hindi babies are very good at it at 12m
* babies are born with the ability to distinguish non-native vs native distinctions, but it eventually declines in non-native lan
babies who are worse at distinguishing native (then non-native) in the second half of the first year of life grow up to have better/worse vocab by age 2
worse
t/f babies are born with different categorical distinctions for sign than they are for speech
false. they’re same
there are aspects of languages that have a critical period (hence why we get accents) but ___ is not applicable critical period
vocabulary
t/f your brain is learning all the time
f. needs breaks. open/close periods
Premature birth, w/earlier exposure, does/does not accelerate distinguishing between hindi stops
does not
whats more important experience or brain maturation
brain maturation!
can exposure such as drugs change the critical period exposure time in infants
yes
_____ learning seems to have a critical period. works best at __-__ m of age
statistical
4-7
whats the mcgurk effect? do babies show it?
ex. video of saying /pa/ but they dubbed the video to look like /va/ so we think hes saying /va/ when we have the visual cues
yes
babies can distinguish languages just by watching videos of speakers (in diff. lang). talk about the differences in ages between monolingual and bilingual babies
mono- at 4 months they showed the distinctions (and even 6m) but by 8m there was no diff.
bi- they could distinguish them at 8m still
can bilingual babies maintain sensitive to speaker differences even if they don’t speak those languages? what does this tell us?
yes, * this shows that bilinguals maybe just have a heightened attention system. maybe not entirely about language exposure
