Educationalists agree that intervention with children with delayed development contributes to the actualisation of their potential and prevents many educational problems from developing later, but little research has been embarked on to prove this. This book explains how a research study on a programme of intervention for at-risk children was developed and evaluated. It shows that it was effective in improving the at-risk children's pre-school abilities. All potential researchers of preschool children, educational psychology, education and psychology students, teachers and all those interested in child development will find this book enlightening, encouraging and helpful.
