The traditional concept of "schizophrenia," previously employed to encompass any psychotic process that was neither manic nor depressive, led to two thrusts in childhood classification: The first was the now discredited concept of unitary psychosis (Fish, 1977); the second was the extensive eponymous labelling of childhood syndromes regarded as psychotic (Kolvin, 1971).
