31
Brown Stages of Language Development: Stage 1
Age 12-26 months; about 50 words in vocabulary; basic phrases with communicative intent (e.g., more juice, my doll)--first words; linear simple sentences
32
Brown Stages of Language Development: Stage 2
Age 27-30 months; use of present progressive "-ing", prepositions "in" and "on", and regular plural -2 (e.g, "man running", "in house", "on book", "my kids")-- simple sentences with the emergence of grammatical morphemes
33
Brown Stages of Language Development: Stage 3
Ages 31-34 months; use of irregular past tense, possessive 's, and uncontractible copula (e.g., "me drew", "daddy's hat", "he is sick")--noun phrases, auxiliary verbs, emergence of different sentence modalities (e.g, questions, negatives, imperatives)
34
Brown Stages of Language Development: Stage 4
Ages 35-40; use of articles (a, the), regular past tense, third person regular present tense (e.g., "the bucket", "a drink", "she shopped", "he runs")--emergence of complex sentences, embedding of sentence elements
35
Brown Stages of Language Development: Stage 5
Ages 41-46; use of third person irregular, uncontractible auxiliary, contractible copula, contractible auxiliary (e.g., "doggy does tricks", "he was jumping", "she's happy", "she's dancing")--compound sentences
36
Mean Length Utterance (MLU)
total # of morphemes/total # of utterances ----MLU is usually in line with age
37
Language
Social, rule-governed tool used to send and receive messages
38
Receptive Language
Language comprehension- listening and reading; develops before expression; understanding of language--for example vocabulary, questions, concepts, directions
39
Expressive Language
Language production-speaking and writing; expression of wants, needs, opinions, ideas etc., words and nonverbal communication, gestures, pointing, expressions, grammar
40
Language Form
Consists of phonology, syntax, and morphology
41
Phonology
study of speech sounds and the rules of combining and using phonemes
42
Syntax
rules that pertain to ways words can be formed to make sentences -- word order
43
Morphology
study of rules that govern how morphemes (smallest meaningful lexical unit) are used in a language
44
Language Content
Semantics-meaning of words
45
Semantics
Meaning of words and combinations of words in a language
46
Language Use
Pragmatics-social rules of language; matching language and situation
47
Pragmatics
rules associated with the use of language in conversation and broader social situations
48
Nature Language Theory--Nativist Generative View (Chomsky)
language is innate and pre-specified; we are born with language acquisition device, language is separate from other cognitive systems
49
Limitations of nativist/nature language theory
non0literal language; strict focus on syntax; no single grammar for all languages; no evidence that children need adult-like rules to acquire langauge
50
Evidence for nativist/nature language theory
deaf babies babble, speech and language deficits may be inheritable, children follow sequence of developmental milestones, language aspects learned without direct instructions (e.g., grammar rules), we are born with language acquisition device which determines how we learn language
51
Nurture Language Theory -- Constructionist-Interactionist View
Environment guides language, no processor in brain specific for language, can't separate language from cognitive systems
52
Evidence for nurture language theory
Operant conditioning
53
Language Theory: Cognitive Theory (Piaget)
Children learn language like other cognitive skills (concepts first, then language); language is made possible by cognition and other intellectual processes; observe child in play to determine level of representational thought
54
Language Theory: Semantic Theory (Filmore, Blloom)
Interpretation of messages requires consideration of meaning; acquisition stimulated by child's desire to communicate and knowledge
55
Language Theory: Behavioral Theory (Skinner)
child learn language through conditioning (only what they are exposed to) stimulus-response drives language acquisition; drill & practice- reinforcement
56
Language Theory: Social Interactionism
Encourage social interactions; desire to communication & use drives acquisitions; incorporate caregivers and multiple environments into learning
57
Language Theory: Emergentist Theory
data and pattern driven, child ability to uses cues develop over time; neurologically based
58
Critical Period Hypothesis
Must have adequate stimuli before "critical age" (5-7 years old) or full language command cannot be achieved
