Morphosyntactic development in Italian and its relevance to parameter-setting models: comments on the paper by...

Pizzuto & Caselli (1992) claim that data from the morphosyntactic development of Italian-speaking children are inconsistent with nativist, parameter-setting models of language development. In the present Note it is argued that much of the data which Pizzuto & Caselli adduce is irrelevant to the specific hypotheses they are evaluating and that those data which are relevant fully support parameter-setting and linguistic-theoretic models, contrary to their claims.
