Final Exam Flashcards
What is Morphology?
- creating meaningful units (morphemes), using them to form words
Syntax:
- grammar (sentences form words)
Pragmatics
- context-appropriate use
Prelinguistic abilities timeline:
- cooing (6-8 weeks)
- babbling (4-6mo)
- home language sounds (8 mo)
Precursors to language comprehension
- ability to discriminate between languages
- sensitivity to speech sounds
- memory for words in 8-9 mo
- facilitation of categorization by speech sounds
Words and more during the first year of life:
- holophrases (single words)
- nonverbal information
- intonation: question, demand, request
- nouns first (naming)
When is the vocabulary spurt?
18 months (30-50 words) - 24 months (186 words), with wide individual differences
The speech of two-year olds:
- Telegraphic speech: critical content only (2+ word utterances)
- Functional grammar (semantic relationships are expressed, context is important)
- Rules are inferred from adult speech (no one knows how)
- Age 2.5 (or earlier) - appreciation of syntax (e.g. Billy hit, vs hit Billy)
What is overregularization?
In the development of grammar - “He eated, two foots, he doos” - strict application of grammar rules, a sign of advancement
Evidence that 2-year olds have some understanding of grammar:
- they generally react differently to ungrammatical sentences than to grammatical ones.
What is fast mapping?
Quickly attaching a new word to the appropriate context
What is the Contrast assumption
Kids assume that each object has only one label.
Speed with which words are learning during the naming explosion:
10 to 20 words per week
Overextension & underextension
Too broad & too narrow
What is syntactic bootstrapping?
A technique by which children derive the meaning of a word from its linguistic context - the syntax
