<p><i>"The scope, depth, refined statistical and methodological sophistication, penetrating critiques, and systematic development and extension of information integration theory and functional measurement that have made Norman Anderson a giant of our time are displayed once again in this book....no one since Piaget has approached so diverse a collection of important areas of psychology and brought such an integrated perspective that unites and illuminates them all....The book is rich in ideas and provides a powerful alternative to the prevailing approaches in developmental psychology....What we have here is an important contribution to developmental psychology."</i><br />—<b><i>American Journal of Psychology</i></b></p>
