| Speech Like Vocalization Stages |
|
Definition
-QRN: 0-2m, open vocal tract, poor resonance -Primitive articulation stage: 2-3m, cooing, more vowel like resonance -Expansion stage: 3-6m, vocal play, marginal babbling - Canonical babbling: 6+m, reduplicated/variegated babbling |

Definition
- Models by definition are mechanistic/ structural. - Most models ignore social and behavioral variables. - We know little about how children actually learn language. The models address more WHAT the process may be than HOW the process takes place. |
