The handbook is composed of chapters by authors who discuss the important features of particular types of toys, provide information related to the developmental importance of this type of toy, discuss social and cultural issues engendered by play with such toys, and review the available research on the characteristics and potential impact on children's developmental progress of toys of that type. Both traditional toys and technological toys are discussed. The handbook is expected to serve both as a reference for educators, parents, toy designers, and other interested readers, and as a catalyst for further research and ongoing toy development. Its purpose includes helping readers to gain knowledge that enables them to more fully appreciate the value of children's toy play, find out more about the favorite toys they had in childhood and relive those satisfying play experiences, and learn how to foster the learning, physical development, and social-emotional growth that comes from such toy play.
