Two experimental studies investigate the extent of 3- and 4-year-olds' relative dependence upon contextual and linguistic information as they discriminate between presentations of Requests from Offers, and Requests from Questions presented in contexts. Contexts are manipulated systematically, and quantity of linguistic information in the presentations is progressively reduced. While younger subjects' discrimination of each speech act appeared relatively unaffected by reduction of linguistic information, the older subjects' performance was relatively adversely affected. We consider a developmental shift in speech act comprehension strategy from an early more context-based approach to a later, more heavily text-dependent approach, perhaps linked to continuing development of linguistic awareness.
