Q

Critical period

A

Q

Infant directed speech

IDS

A

Distinctive mode of speech that adults adopt when talking to babies

  • -> draws the infants attention to the speech itself
  • -> recognition and learning of words is better

Q

Categorical perception

A

Process that allows us to distinguish sounds between categories ( phonemes )

6-8months: infants can discriminate between different languages

10-12months: can’t perceive the difference anymore

  • -> retain their sensitivity to sounds in the native language
  • -> become less sensitive to nonnative speech sounds

The process of discovering where words begin + end in fluent speech

–> emerges after 7-8months

Q

Distributional properties

Study These Flashcards
A

Certain sounds are more likely to appear together than others

–> infants use recurrent sound patterns to fish words out of the passing stream of speech

ex.: own name

20
Q

Babbling

Study These Flashcards
A

Repetitive consonant - vowel sequences

(after 7 months)

–> key component of this development is the exposure to their native language

21
Q

Reference

Study These Flashcards
A

Associating words with a meaning

–> First step in acquiring the meaning of words

22
Q

Productive vocabulary

Study These Flashcards
A

Refers to the words a child can say

  1. children are limited by their ability to produce words clearly enough for recognition

–> this is why they adopt simplification strategies

ex. : brother –> “bubba”
2. first things they say is limited to their immediate environment
ex. : siblings, pets

!! Infants understand more words than they can produce !!

23
Q

Holophrastic phase

Study These Flashcards
A

Expressing a whole phrase with a single word

24
Q

Overextension

Study These Flashcards
A

Using a word in a broader context than is appropriate

ex.: dog –> every four legged animal

–> represents an effort to communicate, rather than lack of knowledge

25
How can adults influence the learning of speech of infants ?
1. IDS 2. highlighting new words 3. Repetition of words 4. naming games ex. : "ich sehe was was du nicht siehst"
26
Fast mapping
Process of rapidly learning a new word from hearing the contrastive use of a familiar word + unfamiliar word ex.: "bring me the chromium tray, not the red one"
27
Mutual exclusivity assumption
Children will expect a given entity will only have one name --> bilingual children will not follow this assumption
28
Whole object assumption
Children expect a novel word to refer to a whole object rather than to a part/ property/ action
29
Pragmatic cues
Aspects of the social context are used for word learning ex. : adults focusing of attention - -> relation between eye gaze + labeling ex.: emotional Response of adults
30
Syntactic bootstrapping
Strategy of using the grammatical structure of whole sentences to figure out meaning
31
Telegraphic Speech
Term describing children's first sentences that are 2 - word utterances --> function words + auxiliary verbs are missing
32
Overregularization
Speech errors in which children treat irregular forms of words as if they were regular ex.: instead of go --> went they will say "goed" --> parents will more likely correct factual errors than grammatical errors
33
Private speech
Children talk to themselves as a strategy to organize their actions --> this is then internalized into thought
34
Collective monologue
Conversation in which the content of each childs turn has nothing or little to do what the other child said
35
Behaviorist theory of language development | Skinner
Parents teach children to speak by means of the same reinforcement techniques that are used to train animals
36
Universal Grammar | Chomsky's nativist theory
Refers to a hard wired set of principles + rules that are common to all languages - -> every human is born with - -> explains why most children learn language with such rapidity
37
Modularity hypothesis
The human brains contains an innate, self contained language module that is separate from other aspects of cognitive functioning
38
Speech stream
Undifferentiated series of speech sounds --> must separate speech stream into individual sounds to learn the relevant sounds of their language ex.: wheredidyougowithgrandpa ?
39
Discrimination of different sounds in adults
a) can distinguish sounds from different categories ex. : "ba" vs "pa" b) can't distinguish sounds from the same category ex. : different "ba" sounds --> suggests that infants engage in categorical perception of sounds
40
Ability to discriminate between phonemes in infancy
< 6 months : Ability to discriminate between a wide range of phones > 12 months: Experience diminishes this ability --> infants are unable to discriminate between phonemes of other languages, just native one
41
What does a childs acquisition of the phonemes of its native language depend on ?
a) innate predisposition for categorical perception b) experience - -> necessary for the infant to learn which phonemes are most important to the language
42
The development of speech production
0-2 months: REFLEXIVE VOCALIZATIONS - -> cries, burps, coughs - -> different types of cries might have different meanings 2-4 months: COOING + LAUGHING - -> is produced while child is in a happy state - -> reciprocal cooing might teach turn taking in conversations 4-6 months: BABBLING + VOCAL PLAY - -> gaining control over vocal cords, lips, mouth, tongue - -> infants produce a wide range of sounds 6-10 months: CANONICAL BABBLING - -> production of sound combinations that sound like words ex. : "mamama" 10 months +: MODULATED BABBLING - -> Overlaps with the beginning of meaningful speech - -> acquisition of the intonation patterns important for the native language (knowing difference between statement + question) 2 years: ability to combine words into simple sentences
43
``` S structure (Surface structure) ```
Sentence that can have more than one meaning --> its meaning is determined by the d-structure "There was a shooting in the mall yesterday" --> may refer to an armed shooting or photo shooting
44
``` D structure (Deep structure) ```
More abstract representation of a sentence
45
Creative overgeneralizations
Creating new verbs by treating a noun as if it were a verb ex.: "why is it weathering ?"
46
Voice onset time | VOT
The time delay between when a sound begins and when the vocal cords begin vibrating
47
Initial perceptual bias
Initially infants have a bias towards familiar sounds they picked up in the womb --> mothers voice, songs etc
