Universals
•
•
•
•
Are there basic patterns to babbling?
Are early word orders universal?
Does UG give children a universal set of
functional categories?
Is the vocabulary spurt universal?
We need LOTS of data

Differences
•
Do children have individual styles?
• Gestalt vs. Analytic
• Enactive (1S) vs. Depictive (3S)
Do children respond differentially to
parental recasts?
• Do children vary in their match to cue
validity?
Again, we need LOTS of data.

Comparisons
•
•
•
How should we match SLI children to
normal controls -- MLU? Morphology, TTR
How should we compare language
socialization processes across social
classes? Between cultures?
How should we compare the course of
development across languages? The case of
Romance.
