First Published in 1998. The authors’ aim in editing Interaction in Action is to follow up on the thinking and practical guidance contained in their previous work on Intensive Interaction: They hope to illustrate that Intensive Interaction is not just something that goes on in hospital schools. Here we see the approach used not only by teachers, but also by speech therapists, occupational therapists, social workers, psychologists and parents. We see the approach used in people's homes as well as in education and day centres. The contributors have been asked to share their insights, the way they think about Intensive Interaction as well as the way that they 'do' it. This means that the chapters contain both reflective analysis and vivid description. The contributions illustrate how Intensive Interaction has grown and developed as an educational approach and as a way of being with people, and they illustrate the impact on all those involved.
