Q

Categorical Perception

A

Perception doesn’t always change just because physical properties do

Q

McGurk Effect

A

Phoneme categorization can be affected by visual info

-Infants dishabituate and seem interested in perceiving /da/ when audio is /da/

Q

Functional Reorganization

A

Native language phonemes built from universal perceptual categories, helps to learn words

  • Innate

Q

Speech production stage 1

Study These Flashcards
A

Reflexive vocalization

  • birth to 8 weeks
  • automatic responses to environment
  • hunger cry, pain cry, temper cry
20
Q

Speech production stage 2

Study These Flashcards
A

Cooing

  • 2-4 months
  • intentional vowel-like sounds
  • /e/ and /u/
21
Q

Speech production stage 3

Study These Flashcards
A

Isolated vowel-like sounds

  • 4-7months
  • pre-canonical babbling
  • vocal experimentation
  • vocal tract changes- soft palate shifts up, tongue separates from jaw
22
Q

Speech production stage 4

Study These Flashcards
A

Canonical babbling

  • 7 months on
  • reduplicated babbling
  • true words
  • variegated babbling 12 months on
  • jargon babbling
23
Q

Why do infants babble?

Study These Flashcards
A

Motor development, language development

24
Q

Babbling sounds

Study These Flashcards
A

12 most frequent consonants make up 95%- stops, glides, nasals

25
Jaw oscillation theory
Alternating between open and closed vocal tract due to single action -Vowels= resting tongue
26
Jaw oscillation consonants and vocal tract
- Bilabial (b,p) consonants with central vowels (a)= neutral tongue - Frontal (t, d) consonants with front vowels (i)= tongue stays front
27
Chain shift
Substitute a different sound (guck for duck)
28
Stored articulatory routines
Can't generalize sounds to other contexts
29
Syllable Simplification
Cluster Reduction- stop to top Final Consonant Deletion- bat to ba Reduplication- doggy to dada Weak Syllable Deletion- banana to nana
30
Fast Mapping
"Give me the chromium crayon" then repeat a week later | -mapping between sound and representation
31
Original word learning theory
people show kids objects then tell them the name
32
Word learning constraints
Biases that limit the hypotheses that the child entertains
33
Taxonomic Constraint (word learning constraint)
- Assume words refer to category of things that are the same - Assume words don't refer to category of things that have related associates Cake---> other desserts, other candles, NOT kinds of parties or kinds of lights Extension of novel words- categorization, "dax"
34
Whole object constraint (word learning constraint)
- Assume that word refers to entire object - Don't assume that word refers to part of object, its substance, its color Whole object bias helps us learn nouns but slows verbs, adjectives, etc
35
Mutual Exclusivity (word learning constraint)
- Assume every object has one name - Assume there are no synonyms - Can override whole object constraint
36
Social cues in word learning
Word learning occurs socially, child is attempting to discover another's intent to refer
37
Joint Reference
When speaker and listener both interpret a phrase as the same thing
38
Follow-in labeling
Mothers label the object a child is looking at
39
Disjoint labeling
A parent isn't talking about the object the child is looking at
40
Why do children learn nouns before verbs
3 hypotheses: 1. Input determines word learning- children learn words that parents directly teach 2. Limits of cognitive development- infants don't have abstract concepts/words 3. Limits of linguistic development- relational words relate concrete words
41
International Adoptees
Lose native language and switch to new language, by adulthood no evidence of native language. - verbs increase as vocab does - no difference in vocab composition in adopted vs infant learners - shifts from nouns to verbs are not cognitively driven - adopted children actually learn words faster - vocab and syntax work together
42
Children's morphology
- smallest unit that has meaning - start to appear in two-word stage - first acquisition is present (ing) and last is auxiliary contractable (she's going to school) - tend to over regulate past tense and plural
43
How to children learn morphology? (theories)
1. They memorize 2. They analogize 3. They go by rules
44
Linear syntax
pronoun cannot precede main referent
45
Co-referential syntax
pronoun cannot c-command main referent | -children know principle C
46
C-command
Node B commands node __ only if: - B does not dominate __ - ___ does not dominate B - The first branching node that dominates B also dominates ___
