EXAM 1: Dr. Kuhl Flashcards
Phonetic Boundary
The boundary that separates one phoneme from another (aka R/L)
Infants are very sensitive to this distinction for all 40 phonemes, citizens of the world
Native Language Neural Commitment
Differentiating native language to foreign sounds
Minimal Pair
Pair of words that differ in only one phoneme
Rake/Lake are minimal pairs
/r/ and /l/ study
Japanese infants more exposed to unimodal distribution, does not differentiate between /r/ and /l/ sounds
English infants are more exposed to bimodal distribution, does differentiate between /r/ and /l/
Statistical Distribution
Infants learn to differentiate their native language sounds based off of the distributive frequency in how often they hear certain phonemes
Mandarin and social interactions study
Infants placed in face-to-face mandarin sessions distinguished much more mandarin phonemes compared to the control/visual/audio groups.
important of SOCIAL INTERACTION in learning language
Transitional Probability study
Infants could track the statistical probability of certain phonemes coming after another phoneme i.e. (Pi comes after Tu in the word TUPINO 100% of the time)
Statistical Distribution test with ta/da distinction study
Infants split into two groups, one listened to unimodal distribution between ta/da and the other listened to bimodal distribution of /ta/ and /da/.
Unimodal group could not distinguish the difference between /ta/ and /da/ while bimodal could differentiate it (proved by looking times, bimodal group looked longer at the unfamiliar nonalternating 3/6 (unimodal)
IPA symbols
1:1 ratio with sound unlike English alphabet
Lack of Invariance
(too much variability)
Allophones
Coarticulation (1st sound prepares to make 2nd sound, a form of assimilation, cause of allophones)
Aspiration/Unaspiration
Allomorphs
Speech Perception includes:
Categorical Perception
Statistical Perception
Visual cues
Social interaction
Audiovisual Perception experiment
When children had their lips and sound matching, looked longer at mismatching sound (novel)

Gestures
Parental gesture leads to children gesture use, which leads to increased vocabulary
Generally, greater SES families used more gestures
