The developmental psychology of pre-school children is a very important specialized basic theory course for those studying for pre-school education majors. It is a very practical text. It elaborates the basic rules and features of the psychological development of children from birth to the point at which they start school. It functions not only as a basic course for pre-school education practitioners who are just getting into the field, but also as an excellent companion for pre-school education practitioners aiming to encourage the psychological development of children according to objective laws, and so avoiding inefficiency in their work.
