Language Development

Question 1

Langauge

Answer 1

structured, rule based system of communication using symbols to communicate meaning
Symbolic
Expresses meaning
Generative
Structure/rule-based

Question 2

Language is symbolic

Answer 2

Written word, spoken word, signed word, etc. all conjure up same mental image

Question 3

Language expresses meaning

Answer 3

When interpreting what’s being said you know they are expressing something meaningful
Elements that influence interpretation of meaning

Question 4

Language is generative

Answer 4

Infinite number of sentences
All are interpretable by those who speak our language
Generate and interpret every sentence you haven’t heard before

Question 5

Language Requires

Answer 5

Comprehension and production
Human brain and environment

Question 6

Comprehension

Answer 6

Understanding what others say, sign, or write
Receptive vocabulary: what words you’d understand if you encountered them

Question 7

Production

Answer 7

Speaking, signing, or writing to others
Productive vocabulary: what words you can spontaneously use yourself

Question 8

Phonemes

Answer 8

Units of sound that compose speech
Change of phoneme changes the meaning of the word
Varies dramatically across languages
E.g. rake vs. lake
Phonological development: acquisition of knowledge about the sound system of a language (during first few years of life)

Question 9

Morphemes

Answer 9

Smallest units of meaning
Alone or in combination constitute words
E.g. doghouse has two (dog + house)
Semantic development: learning the system for expressing meaning in a language
Semantics: study of meaning

Question 10

Syntax

Answer 10

Permissible combinations of words from different categories (e.g. nouns, verbs, adjectives)
Syntactic development: process of learning to understand (and follow) the syntactical rules of one’s language (intuitive)
Universal grammar: set of highly abstract, unconscious rules common to all human languages (Noam Chomsky)
-sentences can make sense grammatically but not mean anything

Question 11

Pragmatics

Answer 11

Understanding of how language is typically used in a specific cultural context

Question 12

Brain-Language Lateralization

Answer 12

Hemispheric differences in language functioning
For right handed people language is primarily represented and controlled by left hemisphere
Left hemisphere predominantly processes linguistic stimuli from early in life (reasons unknown)
For sign language as well

Question 13

Sensitive Period for Language Development

Answer 13

Time during which language develops readily and relatively effortlessly
From birth until somewhere in elementary school (exact end may vary)
Genie who was deprived of early linguistic experience and therefore didn’t ever fully speak properly

Question 14

Bilingualism

Answer 14

Cognitive benefits to children who speak multiple languages
Best to start learning both as young as possible
Similar vocabulary sizes to monolinguals
Do better on executive function and cognitive control tasks
Improved cognitive flexibility from switching between languages

Question 15

Infant Directed Speech (IDS)

Answer 15

Exaggerated speech accompanied by exaggerated facial expressions
Infants prefer IDS (because it is happy speech)
-when affect is constant preference disappears
Infants learn and recognize words better when presented in IDS

Question 16

Prosody

Answer 16

Characteristic rhythmic and intonation patterns with which a language is spoken
Part of why languages sound so different from each other

Question 17

Categorical Perception

Answer 17

perceiving speech sounds as belonging to categories

Question 18

Voice Onset Time (VOT)

Answer 18

Length of time between when air passes through the lips and when the vocal cords start vibrating
E.g. VOT is shorter for b than for p
Young infants make more distinctions than adults do (at 8 months, not at 12 months)
Adults do not perceive differences in speech sounds that are not important to their native language
(perceptual narrowing)

Question 19

Word Segmentation

Answer 19

Where the spoken words start and end
Words are distinct when written down but blend together in spoken speech
7M: Listened longer to words that they had heard in the passages of fluent speech
Infants remarkably good at picking up regularities in native language that help find word boundaries

Question 20

Distributional Properties

Answer 20

Sounds that are part of the same word more likely to occur together than others
Sensitivity to regularities of speech demonstrated in infants
Infants as young as 4 ½ months listen longer to repetitions of their own name

Question 21

Babbling

Answer 21

Between 6-10 months
Consonant-vowel sequences
Drawn from limited set of sounds, some not in native language
ASL babies babble with their hands

Question 22

Early Interactions

Answer 22

Learning to take turns in social interactions
E.g. in peekaboo
Infant has opportunity to alternate between an active and passive role
Responses to babbling serves this function
12 months: understand communicative nature of pointing, many can point themselves

Question 23

Early Word Recognition

Answer 23

6 months
When hear mom or dad, look toward picture of correct person
Infants can understand far more words than they can produce
Same for autistic toddlers

Question 24

Early Word Production

Answer 24

Any specific utterance consistently used to refer to or express a meaning
First word produced around 10-15 months
Mispronounced in a variety of predictable ways
Often refer to family members, pets, important objects, routines
\

Question 25

Stress Patterning

Answer 25

Part of prosody First syllable in two syllable words more likely to be stressed 8 months: expect stressed syllables to begin words and can use this info to pull words out of fluent speech

Question 26

Overextension

Answer 26

using a word in a broader context than is appropriate E.g. calling any four legged animal a dog

Question 27

Underextension

Answer 27

using a word in a more limited context than appropriate E.g. dog only refers to their pet dog

Question 28

Holophrastic Period

Answer 28

window in which children use single words to communicate whole ideas

Question 29

Vocabulary Spurt

Answer 29

18 months: about 50 words (variable) Rate of learning accelerates from there Originally proposed to be point in development where exponential growth suddenly occurs Recent reviews suggests it’s not all that universal or all that exponential

Question 30

Fast Mapping

Answer 30

rapidly learning a new word simply from hearing the contrastive use of familiar and the unfamiliar word Monolingual infants: every object has one word

Question 31

Cross-Situational Word Learning

Answer 31

using repeated co-occurrence across situations to map new words to their referents

Question 32

Pragmatic Cues

Answer 32

using social information to learn words (e.g. eye gaze)

Question 33

Syntactic Bootstrapping

Answer 33

figure out meanings of new words by using grammatical structure of sentences in which the words occur

Question 34

Technology & Language Learning

Answer 34

Parent teaching group showed greatest vocabulary development If parents liked the DVD, they thought their child learned more from it Passive viewing doesn’t support learning, but if actively engaged do learn

Question 35

First Sentences

Answer 35

End of second year start combining words into simple sentences Telegraphic speech: two word utterances Some children use short utterances for long time, others move on to 3+ word sentences

Question 36

Grammar

Answer 36

Tool for building new words and sentences Children as young as 4 know to apply the s for plural Parents play limited role in grammatical development Provide model of correct speech and fill in missing parts of children’s utterances

Question 37

Over-regularization Errors

Answer 37

Treat irregular forms as if they were regular E.g. mans, goed, mooses Most children begin by saying the correct one and relapse to this

Question 38

Collective Monologues

Answer 38

content of each child’s turn having little or nothing to do with what the other child has just said Eventually become better able to stick to topic with conversational partner and talk about the past

Question 39

Narratives

Answer 39

descriptions of past events that have the form of a story 5 years Parents help children produce coherent accounts of the past by scaffolding conversations

Question 40

Conversational Skills

Answer 40

Lag behind speech and language skills Speech is often self directed (e.g. private speech to organize actions)
