Chomsky's work, which is based on three lectures at the University of Berkeley, serves as a kind of summary of his linguistic research. Chomsky defines linguistics more as a subfield of psychology. Thus, grammar has the task of proposing hypotheses about what Chomsky calls linguistic intuition or intuitive, unconscious knowledge. Chomsky counters the latent, normative awareness of linguistic structures against behaviorist attempts to reduce language to language behavior and competence to ability.
