Psychogenic forms of school desadaptation

By psychogenic forms of school desadaptation are understood a child's psychogenic responses, disturbances and personality developments which interfere with his objective and subjective status in the system of learning and impede the teaching-educational process. Some underlying factors are considered (particularly individual psychological characteristics, conditions of family upbringing, etc.) as well as clinical forms (responses to stress, neuroses, psychogenic personality developments) and principles of prevention and correction.
