A general framework for the study of the acquisition of grammar is proposed as a means toward a decision between competing theories, e.g. innate versus learned. The different functions of grammatical acquisition are distinguished as modules such that each represents a separate task for a comprehensive theory of the child's acquisition of grammar. The notion of an ‘analysis device’ is contrasted with that of a ‘behavior-contingent’ device. Some aspects of the operation of behavior-contingent devices are subjected to simulated experiment; the results suggest that response-learning theories and behavior-contingent models cannot be ruled out a priori and may, in fact, be developed into powerful tools in the study of the acquisition of grammar.
