People with Down Syndrome show a specific developmental profile with strengths in social understanding and visual learning and memory, and more difficulties with motor processes, speech and language, and auditory-vocal short-term memory. It is important that parents, practitioners and teachers know this and adapt interventions and educational approaches to take account of this particular profile. This is the only book to date that explains the developmental profile of people with Down Syndrome from its many different angles. It covers a range of perspectives, including the biology, psychology, speech and language, health care, and social competence of both children and adults with Down Syndrome. All the information is gathered and placed in the context of the neuro-genetic science that is developing around this area.
