Essential for anyone involved in evaluating intelligence of adolescents or adults, this book is exceptionally comprehensive, yet accessible. With comprehensive coverage of clinical and neuropsychological assessment of intelligence, the main focus of this book is on the latest edition of the Wechsler Adult Intelligence Scale and interpretation of this widely used instrument. A stronger emphasis has been placed on cross-battery assessment and the scope has been broadened to cover a wider variety of intelligence tests and neuropsychological instruments.
