ABSTRACT
The Developmental Psychology is concerned with the psychosomatic development of the child from birth to maturity; and it attempts to indicate how the child mind develops and matures as body grows, and what particular phases or stages and peculiarities thinking processes and subsequent activity pass through. For analyzing or criticizing the theories of Piaget, one has to remember the long period of time during which Piaget has experimenting and developing ideas. Piaget's first full description of child development will be found in The Language and Thought of the Child, published in Paris. In the very brief and inadequate statement of Piaget's idea of the development of the schemata, two criticisms are already anticipated and partially answered. The criticisms of Piaget's work stem from the fact that books are not particularly easy to read since presents theories in a technical, abstract, even Piagetian vocabulary.
