A critical examination of Piaget's theory of child mentality

This thesis represents an attempt to exmine critically the theory of child mentality put forward by Professor Jean Piaget of Geneva. By experiment and observation Piaget has collected much valuable data from the children attending the Maison des Petits de l'Institute Rousseau: his results together with a somewhat novel theory to explain them are contained in his four volumed "The Language and Thought of the Child," "Judgegment and Reasoning in the Child," "The Child's Conception of the world " and "The Child's conceptoin of Causuality."
