Term | Definition |
---|---|
"True words" | Stable phonetic forms that are used consistently by the child in a particular context Resemble the adult word form phonetically |
0 - 6 months... | ATTEND to social partners. Participate in social interactions (eye contact, smile/laugh in response to adult interaction) |
Joint attention | -eye gaze, requests to look, pointing. (6 - 12 months...) |
Intentionality/goal directness | -baby begins to encode messages for someone else. Gestures demonstrate ability to plan and coordinate to achieve goal - no more trial and error. (8 - 9 months...) |
Intentional communication | -bid for attention accompanied by gesturing, pointing, showing, vocalizing (6 - 12 months...) |
Representational competence | -anticipation of future events, object permanence, symbolic play. (6 - 12 months...) |
Why do babies babble? | 1) exercises/stabilizes the vocal mechanism; 2) social attention; 3) self-soothing (it feels good). |
5 stages of babble | 1.Phonation stage 2.Coo-goo stage 3.Expansion stage 4.Canonical stage 5.Variegated stage |
Phonation stage | Reflexive and vegetative sounds (crying, burping, etc) [birth to ~1 month] |
Coo-goo stage | Back vowels (ah and ooh) with occasional consonant-like sounds (“contoids”) [~ 2 to 3 months]. |
Expansion stage | Variety of vocalizations emerge; yell, growl, squeal, “raspberries” etc. (“vocal play)” [~4-6 months] |
Canonical (reduplicative) stage | Strings of nearly identical C’s and V’s appear (“bababa,” “mama” bo-bo-bo”…) Diverse consonant-like elements are used, with a preference for early-developing sounds in the native language. Still “non-meaningful” [~6-9 months] |
Variegated (jargon) stage | No longer only reduplicative. Adult-like prosody. Connected syllable strings resembling conversational speech with few real words present. Gestures, pointing etc. accompany vocalizations. [~ 9-12 months] |
High babblers | Some evidence that babies who produce complex babble (with diverse “contoids”) become more advanced early talkers. Little evidence of sustained superiority. |
Low babblers | There is little evidence of risk for later speech or language problems. May be monitored, but rarely will require intervention. Watch for emergence of words at next stage. |
Non-babblers | If no vocalizations by 12 months, referrals are appropriate. We want to rule out hearing problems, oral-structure deficits, or developmental delay. |
Features of "motherese" that facilitate infant participation: | Short utterances. Small object-centered vocab. Topics limited to here and now. Heightened facial expressions and gestures. Frequent questions and greetings. Turn-taking. Paralinguistic modifications. Verbal rituals. |
Co-requisites for early communication development: | 1) Cognitive dev. 2) Auditory perceptual dev. 3) Speech-motor dev. 4) Intact care-giver interactions |
