"This handbook brings together such a wealth of material to constitute possibly the single best reference book in its subject area and, as such, should serve as a key text for advanced students, researchers and practitioners." (Psychologist, 1 May 2011) "Overall, the handbook is a thoughtful and valuable reference work, to which users can refer for an impressive range of research." Julia Carroll, Journal of Child Psychology and Psychiatry, 44:6 "Though the structure of this book is similar to other volumes in the series, I welcome it with even greater enthusiasm than the rest. While they all summarise and review the latest scientific research in their particular area of child development, research in the field of infant cognition has, in the last few years, completely overturned all previous conceptions. This volume, therefore, not only summarises and updates the literature in its field, but also replaces much of it ... at the moment this book series is the cutting edge ... As with other volumes in the series, all libraries serving postgraduate level studies in psychology and related disciplines should seriously consider acquisition." Martin Guha, Librarian, Institute of Psychiatry, Reference Reviews, 17 February 2003 "Summing up: Highly recommended. Upper-division undergraduates through faculty and professionals." K.L. Hartlep, California State University, Bakersfield, Choice, March 2003 "The book is a timely addition to to the literature on infant and child cognitive development... The significant value of this volume lies in the breadth of its coverage and the sheer comprehensiveness of its execution... For academics and researchers in the field of infant and child cognitive development this is an invaluable resource that encompasses the current state of knowledge in this central developmental area." Mark Tomlinson. Journal of Child and Adolescent Mental Health 2005, 17(2)
