"...this is an excellent book that provides a valuable introduction to the nature-nurture debate...Ceci and Williams have selected papers...which are...thorough, thought-provoking and wide-ranging...Every chapter is stimulating, and the range of topics covered gives an indication of how important it is for psychologists to understand the subtle interplay between genetic and environmental factors in development. The book is also pleasingly presented and has clear charts, diagrams and tables. It is a book that I hope will find a wide readership." The Psychologist, December 2000
