Sterba treated a delinquent eight-year-old girl by 're-education based on psychoanalytic knowledge'. Dispositional factors (both parents of 'instinctual character') and constantly changing poor environment had caused a pseudo feeblemindedness and an arrest at the autoerotic stage. Sterba states that without child-analysis, but by her specific (permissive) behavior alone, she 'made possible the belated formation of a superego' by incorporation. Treatment extended over three months, four sessions weekly; results were most satisfactory and a normal development was observed over ten subsequent years. It is pointed out in conclusion that this kind of therapeutic method offers much as a prophylactic measure against juvenile delinquency and that at any time the relation can be carried over into a real child-analysis.
