Firstly, the Behaviourist theory developed by Skinner, is based on the conditioning theory. According to it, FLL is a process of imitation and reinforcement. Learners have a set of habits which will enable them to respond correctly to different stimulus. However, when children are learning a FL they are not totally immersed in the foreign culture. Consequently, sometimes they don’t know how to react to the stimulus they are exposed to. Because of this, teachers must try to reproduce the cultural environment of the FL. One way to do this is through contextualised drills, which will enable the students to repeat the appropriate language within a given situation. In this way, language can be broken down into a set of habits and the different situations will suggest the appropriate language to use. As I said before, behaviourism had a great influence on the teaching of FLs, especially, on the Audio-Lingual Method.
