Kemper Fall 26
Preverbal Behavior
Combination of eye contact, eye gaze, vocalizations, gestures which are used with purpose and intent to send a message
Joint Reference: Phase 1
Caregiver calls attention to object “look”
Recognizes caregiver’s pitch as a signal for joint attention
Joint Reference: Phase 2
Efforts to communicate intentionally emerge- pointing to create joint reference
May reach for an object & look to caregiver for response
Joint Reference: Phase 3
Use combination of gestures & vocalizations to show interest in objects
Joint Reference: Phase 4
Demonstrates control over the topic, produces name of objects & events
Qualities of motherese
Pitch, loudness, simple sentences, exaggerated facial expressions, slower, longer pauses, references made to items in frame, regular rhythm, repetition, face to face interactions
Expansions
When an adult repeats what a child says adding additional words to utterance
No change to order of words
Complete form
Extensions
When adult repeats a child’s utterance adding additional words, structure, and new info. to utterance
Adds semantic info. to utterance
“big red cow”
Why does child directed speech matter?
Relates to child’s IQ and lang. abilities
Predicts academic success
Fast mapping/word learning
Children attend to the semantic meaning first then with repeated exposure to the word begin to attend to the phonological representation
Tendency to learn words more easily that are similar, occur often in their environment, and belong to a category
Semantic Feature Hypothesis
Functional Core Hypothesis
Slow mapping
Process of expanding and fine-tuning word meanings
Requires experiences with the word in multiple contexts
Lengthy process that develops along with cognition and linguistic skills
Prelinguistic Behaviors
3 Stages of the Speech Act
Deictic Gestures
Representational Gestures
Stages of Gestural Development
5.5mo-14.5mo: regulates to behaviors of others
6.5mo-1.5yr: social interaction
7mo-1.5yr: joint attention
Stages of Development for imitation skills: 0-6mo
Imitates body movements, facial gestures
Stages of Development for imitation skills: 6-9mo
Imitates simple actions with objects
Stages of Development for imitation skills: 9mo
Deferred imitation
Stages of Development for imitation skills: 10mo
Attempts to complete more sophisticated action
Stages of Development for imitation skills: 9-12mo
Imitates combined action sequence
Protodeclaratives
Used as a way to establish joint attention
Protoimperative
Pointing/gestures to gain control over the behaviors of others
Communicative Functions
Instrumental, regulatory, interactional, personal
Properties of First Words
People, object, actions, social greetings
Ways we categorize first words
Function, semantics, syntax/grammar
Halliday’s Communicative Functions
Interacting, regulatory, personal, heuristic, instrumental, imagine, informative
Dore’s Primitive Speech Acts (PSA’s)
Labeling, answering, requesting action, requesting answer, calling, greeting, protesting, imitating, practicing
Presupposition
Assumptions the speaker makes concerning what the listener knows about the subject of the convo.
Conversational Turn-Taking
Use basic knowledge about the object and comments on it rather than just imitating the word
Difference between free vs. bound morphemes
Free: words that stand alone
Bound: added to words
Difference between derivational vs. inflectional morphemes
Derivational: prefix or suffix, changes class or category of word
Inflectional: only suffixes, make grammatical adjustments to word (plural, possession)
MLU
Mean length of utterance
How is MLU calculated
Collect language sample, count morphemes, divide
MLU = # morphemes / # utterances
Brown’s stages of syntactic development
Use to describe & track grammatical development
Measures average number of units of meaning
Forms of language stimulation
Infant-directed singing, rhymes, stories, television
Factors affecting language acquisition
Race, ethnicity/culture, region, gender, situation/context, peer groups, first language, social class
Cooing
Prelinguistic vocalization that is soft, vowel-like sounds to practice speech sounds (ooh, aah)
Babbling
Combining consonants and vowels (baba, dada, mama)
Replicated babbling
Repeating identical consonant-vowel syllables in strings (bababa, dadada)
Variegated Babbling
Combining different consonant and vowel syllables (ba-da-goo)
Jargon
Long strings of unintelligible sounds but sound like speech
Protowords
Invented, user-specific words (pati for paci)
Language Sampling
Analyzes a child’s spontaneous, natural language in context
What does language sampling give us or what can we gain from it?
Can calculate metrics like MLU
Language Sampling Function
Evaluate true communicative competence in real-world contexts
Language Sampling Semantics
Analyzing vocabulary development, word meanings, concept recognition, relationships between objects/events/people
Language Sampling Syntax/Grammar
How a child combines words to form phrases/sentences
