Abstract

Theories in the behavioral sciences are constrained so that stated relationships are empirically testable and explanations have predictive power. These constraints constitute the classical paradigm, and are trivial just when ?causal relationships? do not hold. It appears that such relationships do not hold for linguistic, and presumably other, behaviors, thus precluding study within the classical paradigm. This compels study of those behaviors in terms of the non?traditional approach to testability and explanation developed in Chomskyan linguistics. These constitute the grammatical paradigm. The existence of two paradigms requires that any inquiry begin by determining which paradigm is appropriate.
