An examination of the child's neuro-psychic neuro-psychological development is more difficult than the study of structural development/ismail.
Because there is a measure to show what is normal and what is abnormal, so there is a judgment about the development of the hand. However, the definition of normal and abnormal in the spiritual area is more slippery. Because of the complexity of the so-called mental function (or psychic function), many elements enter into the structure of many uncertainties. Their measurement and evaluation is the specialty.
