She also stresses the importance of identifying each individual's nonverbal language - which can be visual, tactile, kinaesthetic, auditory, olfactory or gustatory - to establish verbal communication.

Reflecting recent research and changes in terminology, the book explains why some approaches may work for some autistic children but not for others, and the 'What They Say' sections allow the reader to see through the eyes of autistic individuals and understand their language differences first-hand. 'What We Can Do to Help' sections throughout the book give practical recommendations for helping autistic individuals use their natural mechanisms to learn and develop social and communicative skills.

The final chapters are devoted to assessment and intervention issues with recommendations for selecting appropriate methods and techniques to enhance communication, based on the specific mode of communication a person uses.
