Child Growth And Development Theories: A deficiency of growth hormone during infancy results in the development of a dwarf; these individuals are not deformed and are normal in intelligence and sexual development. An excessive production of growth hormone during infancy or child growth and development theorieshood will lead to the development of a giant. When growth hormone begins to be produced in excessive quantities after normal growth has stopped, only the hands, feet, and chin enlarge; this condition is known as acromegaly (q. v.).
The child growth and development theories who shows vigorous and well-proportioned growth and has the radiant appearance that comes from good health tends to elicit a favorable response from adults. On the other hand, a small, immature physique may hinder a child growth and development theories's social adjustment, and lower his sense of personal adequacy. Muscular growth, with the accompanying motor facility and strength, makes possible many new activities. Development of the brain and nervous system affect not only the child growth and development theories's intelligence but also his emotional and social adjustment. The reciprocal relation between physical and psychological factors may show up in psychosomatic disturbances.
Piaget's theory of cognitive development has an interesting similarity to the more general genetic theories discussed earlier in that both assume that behavior is determined by the unfolding of structures. In the case of genetic theories, however, maturation is the critical variable and experience is incidental. For Piaget,although the order in which structures devel is a matter of logic and therefore fixed, experier is assumed to be essential to the development each structure. |
