In recent years, there have been a number of efforts to unify various semantic and pragmatic phenomena, including, for example, scalar implicatures, free choice inferences, and plural meanings. A number of recent developmental studies have turned to acquisition data as a means of evaluating the plausibility of such theories. In this talk, I’ll present an overview of some recent findings from our studies, which have examined phenomena such as: free choice, plurals, homogeneity, clefts, questions, neg-raising, disjunction, and tense. I’ll discuss the consequences of some of the findings for semantic theories and for children’s development of enriched meanings more generally.
