Q

First 50 Words

A

acquired by 18 months of age;
nouns predominate–over 60% of lexicon consists of nouns;
most entries are people/animals in child’s environment or objects the child can manipulate;
not all noun types are represented–no collections or abstractions

Q

timing of “vocabulary spurt”

A

cause of and reason for timing is unknown, but may be related to:

(1) development of more articulation control
(2) the role of syntactic patterns–syntactic frames that child can “fill”
(3) underlying growth in cognitive capacities
(4) learning and using words

Q

explanations for the early predominance of nouns:

A
  • child may already have the concept of objects
  • nouns are perceptually/conceptually distinct–represent concrete “things”
  • linguistic predictability makes nouns easier to use (nouns = things, things relate to each other/other words in specific ways)
  • higher frequency of adult use
  • location at the end of adult utterances for emphasis
  • fewer morphological adaptations than other parts of speech
  • mothers prompt children to produce nouns more frequently
  • more frequent in toy play and short maternal utterances

Q

challenges in learning a verb

A

(1) to establish meaning, child must find underlying concept; concepts of verbs are abstract and hard to determine from the physical environment
(2) some describe momentary actions, others have more duration
(3) some nouns can be verbs
(4) child must be able to identify verb in the speech stream

20
Q

with _____ growth and the emergence of _____, the proportion of _____ increases substantially.

A
  • vocabulary
  • grammar
  • verbs
21
Q

early lexicons until about 18 months of age seem to follow a principle of…

A

…mutual exclusivity (if the word means X, it can’t mean Y or Z)

22
Q

2 processes used by children to form internal representations

A

(1) context-bound symbols, attached to a certain event and only used in that context
(2) words used to designate entities, actions, and relationships in several contexts

23
Q

word learning is unlike most other kinds of learning; much of human learning is _____, meaning…

A
  • associative

* …it is learned by relationships of time or location and perfected through repetition

24
Q

in word learning, children attend to these two things:

A

(1) social information, such as eye gaze

(2) a speaker’s intent

25
Q

the semantic-feature hypothesis and the functional-core hypothesis have been proposed to explain…

A

…concept formation and word learning.

26
Q

semantic-feature hypothesis

A
  • child establishes meaning by combining features that are present and perceivable in the environment
  • as children mature, they add or delete features, and the concept becomes more specific, more closely resembling the generally accepted meaning
27
Q

functional-core hypothesis

A
  • concept formation begins with the formation of a function or use meaning
  • focuses on motion features rather than static perceptual features
28
Q

associative complex hypothesis

A

each successive use of a word shares some feature or is associated with a core concept

29
Q

prototypic complex hypothesis

A

the child’s underlying concept includes a central reference, or prototype; the closer the new referent is to the prototype, the more likely it is to be labeled with that name

30
Q

fast/initial mapping

A

formation of a link between a particular referent and a new name; typically quick, sketchy, and tentative

31
Q

underextensions

A
  • overly-restricted meanings of a concept
  • occurs when child tends to stick to “confirmed core” of words
  • common in both receptive and expressive language
32
Q

overextension

A
  • meaning assigned to concept is too broad when compared to the adult meaning
  • occur when a child must communicate about objects that are not inside the “confirmed core”
  • usually limited to expressive language
33
Q

3 general types of overextensions

A

(1) categorical: child uses a word to label a referent in a related category; usually referencing people
(2) analogical: use of a word to label a referent based on inferred perceptual, functional, or affective similarity
(3) predicate statements: child notes the relationship between an object and some absent person, object, property, or state

34
Q

three types of multiword utterances

A

(1) word combinations
(2) pivot schemas
(3) item-based constructions

35
Q

word combinations

A

multiword utterances that consist of roughly equivalent words that divide an experience into multiple units

36
Q

pivot schemas

A

multiword utterances that show a systematic pattern in which one word/phrase seems to structure the utterance by determining the intent of the utterance as a whole; often includes intonational pattern to convey intent

37
Q

item-based constructions

A

multiword utterances that do seem to be following word-order rules with specific words; dependent upon how the child has heard the word being used

38
Q

3 social-cognitive skills required for child to construct multiword utterances

A

(1) plan and create a multi-step procedure toward a single goal
(2) form abstractions across individual items
(3) create item-based constructions

39
Q

second-order symbols

A

syntactic and morphological markers

40
Q

3 lexical characteristics that influence linguistic processing

A

(1) word’s frequency of use
(2) neighborhood density
(3) phonotactic probability

41
Q

word’s frequency of use

A

frequently-used words are recognized by a child more quickly and accurately and produced more rapidly than infrequently-used words

42
Q

neighborhood density

A

the number of possible words that differ by one phoneme; words in less dense neighborhoods are easier to learn

43
Q

phonotactic probability

A

the likelihood of a sound pattern occurring; sound pattern probability is established for the child through experience, and common sound sequences are stored as patterns and used to divide the speech stream into separate words

44
Q

phonological processes

A

systematic procedures used by children to make adult words pronounceable; enable children to produce an approximation of an adult model to speech production

45
Q

reduplication

A

child attempts a polysyllabic word (like daddy) but is unable to produce one syllable correctly, so s/he compensates by repeating the other syllable (resulting in dada)

46
Q

open syllables

A

syllables in multisyllabic words that end in a vowel;

predominate over closed syllables

47
Q

consonant/cluster reduction

A

results in single-consonant production of a consonant blend

48
Q

factors that influence early language acquisition

A
  • individual variation: occurs within and across components of early language
  • level of grammatical complexity: in toddlers, reflects vocabulary growth more so than the age of the child
  • lexical bootstrapping: vocabulary is the foundation for grammar
    syntactic bootstrapping: children can use syntactic knowledge to narrow down word meaning
    *phonological bootstrapping: prosody, phoneme, and syllable information in speech are used by a child to determine both
  • overall health, cognitive functioning, environment of home, middle ear infections (otitis media), motor speech problems, SES, exposure to television, and international adoption and second language-learning
49
Q

language socialization

A

language is central to the process of learning culture;
cultural patterns teach children how to communicate;
intertwined nature of this process = language socialization

50
Q

oral narratives (stories)

A

uninterrupted stream of language modified by the speaker to capture/hold the listener’s interest; narrator maintains social monologue; include self-generated stories, telling familiar tales, retelling of books, movies, or television shows, and recounting personal experiences

51
Q

conversations are ______, while narratives are ______

A
  • contextualized dialogues

* decontextualized monologues
