This approach introduced the four principle language skills for the first time: listening, speaking, reading, and writing. Oral communicative competence became the focus. Comprehensible language input became important and speaking in the target language began to occur, learning about the language was overemphasized.
For a While in the early 1970s there was great interest in applying this Cognitive Approach to language teaching and materials were developed with deductive and inductive grammar exercises. However, no language teaching method ever really developed directly from the Cognitive Approach; instead, a number of 'innovative methods' emerged.
