"For anyone interested in human abilities, their organization, and how effectively to study them, this book is apt to be most engaging. Its foundational emphasis, clarity, consistency, and the appeal of an encompassing methodological system marries together some of the best of the new and old ideas about statistics and psychology." — Robert M. Pruzek, State University of New York at Albany
