The document summarizes three major traditions in second language acquisition: behaviorism, structural linguistics, and cognitive approaches. It focuses on behaviorism and its influence on early approaches like contrastive analysis and audiolingualism which viewed language learning as habit formation. Later, error analysis emerged which saw learner errors as significant and led to the idea of an internal language learning process. Research also found limited evidence for contrastive analysis predictions, pointing to more developmental and innate factors in acquisition.
