The model presented here is based on prearranged situations in which the target behaviour is emitted in a predictable manner within a well-structured and controlled environment. The first step is to draw a clear picture of antecedents in which the target behaviour is likely to occur and the consequences that tend to follow it. The functional analytic literature is rich with many strategies designed to obtain this information, which is then used to design scripts (specific lesson plans), in which the triggers associated with inappropriate behaviour are incorporated, creating an opportunity for behaviour change.
