"...the chapters are informative, well written and 'on top of' the current literature....Challenges to Developmental Paradigms issues the call for the right hand of practice to become aware of what the left hand of theory and research is doing. While the call is easier to sound than to answer, Zelazo and Barr should be commended for having made a worthwhile beginning."—Contemporary Psychology"Thank you for a volume which stimulates and provokes, which displays our fields' creativity and ingenuity in theorizing and in investigating, and which maintains good doses of skepticism and optimism."—Journal of Applied Developmental Psychology"The book is thought-provoking because it challenges or expands present concepts of normality and infant development. It is a scholarly, well-written work that does not attempt to offer any clinical solutions, but does pose very important questions. It should prove useful to a variety of child-health professionals."—American Scientist
