Q

Drive to Create Language

A

When children are raised in an environment with no language, they will create their own communication
system
• Children who are deaf and who are not exposed to American sign language will create gestures to communicate with their family

Q

Language in fetuses

A
  • Fetuses can learn about auditory stimuli
    • Play full-term fetuses recordings of their mom reading a poem or a stranger reading a poem
    • Changes in heartbeat indicate that they could tell the difference

Q

Language comprehension at 6 months

A
  • Prefer to listen to familiar words like “baby”
  • Understand the referent of common words
  • -> when word mom or dad was said would turn to corresponding parent

Q

Production of language from 0 to 6 months

A

0 to 2 months: Reflexive vocalizations
2 to 3 months: Cooing
4 to 6 months: Experimenting with their voice

20
Q

Production of language 6-10 months

A
Babbling
• Canonical babbling
• Babbling with real syllables
• Reduplicated babbling• (mamama)
• Variegated babbling• (bamananapapa)
21
Q

Gestures

A
8- to 12-months
• First gestures
• Holding something up
• Pointing
• Declarative
• Imperative
12-months
• Iconic gestures
22
Q

First words

A
12 months 
• On average, babies say first word
- usually first words are nouns
• 18 months
• Around 50 words
• Holophrases
• Bottle!
• Hug!
23
Q

First Words and Gestures

A

Children will combine gestures and words
• Gesture is linked to later language production
• The more a child gestures early, the more words they produce later

24
Q

Putting Words Together

A

12 months: Speaking first words

• 18 months: Putting two or three words together

25
Learning the Rules of Language
``` Syntax: Word order • Other rules: • Plurals • Verb tenses • Children learn the rules of their language implicitly ```
26
Overregularization
Once children know the rule, they begin to apply it in novel circumstances • Get irregular forms incorrect ex: past tense in english
27
Why is Overregularization Occurring?: Dual-Mechanism Model
Interaction of rule and memory • Blocking principal • Retrieval of irregular form blocks application of the rule • Retrieval failure • To retrieve successfully, you need repeated encounters with the form
28
Behaviorism in language
Language develops from operant conditioning • Input: Lots • Domain specific: No • Weaknesses • Reinforcement is rare/not necessary/often ineffective • Theory predicts that children learning multiple languages at once should be slower, and they are not
29
Connectionism in language
Language results from environmental input • BUT the brain can handle many kinds of information simultaneously • Can generate rules, even when that rule was never explicitly stated • Input: Lots • Domain specific: No
30
Early Empirical Approaches to language
- behaviorism | - connectionism
31
Nativist Approaches
``` Language Acquisition Device • Can acquire all natural languages • Does not have specific rules • Includes abstract principles that guide learning in any language • Input: Little needed • Domain-specific: Yes ```
32
Statistical Learning Approach
Children figure language out by getting lots of input and then working out the patterns
33
Word Segmentation
where the boundaries between words are - can be hard to tell apart sometimes - Some sounds are more likely to go together in a word than are others
34
Transitional probability
likelihood of one sound given a previous sound | - infants as young as 8 mo use statistics to figure out language
35
Fast mapping
The process of rapidly learning a new word through incidental exposure rather than direct teaching - can do this from 2 yo - Fast mapping not limited to word learning • May be limited to linguistically presented material
36
Constraints on Word Meanings
``` Riddle of reference (How do you know what a word refers to?) Shape bias (things with same shape have same name) Whole-object bias (Prefer to label whole objects rather than their parts) Mutual exclusivity (Each object only has one label) ```
37
Children are able to learn new words with limited exposure and without direct exposure How is this possible?
(1) Assumptions about what words mean | (2) Use of social information
38
Can Children Learn New Vocabulary from watching videos?
Older children can learn new vocabulary from a video
39
Can Children Learn to Discriminate Phonemes from Watching Videos?
No, audio/visual stimulation is not enough they need a real person to be there
40
Do Children Learn New Vocabulary from the Television They are Watching ?
- More time viewing Sesame Street predicted greater receptive vocabulary 2 years later, after accounting for receptive vocabulary at Time 1 • Watching other shows did not predict greater vocabulary
41
Do Children Learn Language Equally Well from All Speakers?
infants prefer infant directed speech (IDS) | learn better from IDS than ADS
42
Infant-Directed Speech (IDS)
May make word segmentation easier • Enables learning of new words that children did not learn when they heard them in adult-directed speech (ADS) • Younger infants remember words they heard in IDS better than those they heard in ADS
43
Are Children Choosy About from Whom They Learn Language?
When learning language, children prefer: • Knowledgeable speakers to speakers who express uncertainty • Adults to children; however, children prefer a reliable child to an unreliable grown up • Older 4-year-olds prefer a speaker who uses correct grammar (This is a cup) to one who used incorrect grammar (That are a cup)
44
Critical Period for First Language Learning
Difficult to master syntax after a certain age but not clear what this critical period is
45
Critical period for second language learning
thought to end at around puberty (12-13 years) • Multiple critical periods depending on the aspect of language • For example, earlier exposure may be necessary to achieve optimal understanding of grammar
