The document discusses several theories of emotional and behavioral disorders from a psychoneurological perspective: 1) Congenital, biochemical, and acquired theories examine biological factors such as genetic disorders, prenatal/perinatal events, biochemistry, and physical brain damage. 2) Psychodynamic theory studies unconscious motivations and the interplay between unconscious and conscious processes. Freud's theories of id, ego, superego and psychosexual stages are described. 3) Erikson's psychosocial theory proposes eight stages of social and identity development influenced by social/environmental factors.
