Until the last decade there was considerable confusion about the nosology of childhood psychoses. As Kanner (1958) has pointed out, certain psychodynamically orientated writers (Szurek, 1956; Beres, 1956) have eschewed the important operation of differential diagnosis. This has led to the notion of 'equality schizophrenias' (Darr and Worden, 1951) and thus to the idea of a single psychosis of childhood.
