"This book surveys the history and measurement of intelligence through seven metaphors commonly used in the field: geographical (maps), computational, biological, epistemological, sociological, anthropological and systems. This treatment is extended through the chapters of the book dealing with measurement and discussions of the genetic and environmental bases of intelligence as well as group (sex and race) differences." The Scientific and Medical Network "This book is, therefore, strongly recommended to all serious undergraduate or postgraduate students of intelligence or to anyone interested in the historical development of psychological constructs."
