Language Development Milestones Flashcards
(46 cards)
1
Q
3 variables that impact language development
A
- Innate characteristics - IQ, attention span
- Environment - caregivers, amount of stimulation, SES
- Cultural Expectations - Americans encourage children to talk, not all cultures do as well
2
Q
Motherese aka Child-Directed Speech (CDS)
A
Speech that is slower, higher pitch, with dramatic changes in intonation.
Designed to increase child’s attention.
Shorter utterances with concrete language.
3
Q
Caregiver Role during Infancy
A
- Turn-taking (ex: peek-a-boo) - foundational for pragmatics
- Eye contact - also for pragmatics
- Motivation: if caregiver responds immediately to cry it increases baby’s motivation to communicate. This leads to more frequent & varied interactions
- Quality of interaction (higher quality increases occurrence)
4
Q
Locke’s Model Phase 1
A
Vocal Learning
Prenatal - 5/7 months
Familiarize selves with vocal cues that identify people, social behavior, & expression
Dependent on: Outside Stim (aud/vis/tactile)
Systems: Phonology, Prosody, Pragmatics
5
Q
Locke’s Model Phase 2
A
Utterance Acquisition 5/7 months - 20/37 months "Tax box" & Holphrastic Dependent on: Phase 1 & outside stim Systems: phon, pros, prag. + SEMANTICS
6
Q
Locke’s Model Phase 3
A
Analysis & Computation
20/37 months - 3 yrs

7
Q
Locke’s Model Phase 4
A
Integration & Elaboration
3 yrs +
