Intensive interaction is an approach based on natural conversations at a level that a person can understand and join in with. This is achieved by following the individual's lead and mirroring his or her behaviours and vocalisations.
Once an individual's attention has been gained a sequence of interactions begin which build over time. During the interactions the individual learns the fundamentals of communication (getting a response and responding, reading and using facial expressions, body language, eye contact, turn-taking, vocalising).
One of the most important things an individual learns through the process is that other people are good to be with and that other people enjoy being with them.
