ABSTRACT
The 1950s were an important period in the development of Kleinian practice and thinking because Klein's ideas about psychotic anxieties and defences were tested with severely ill patients, mainly schizophrenics, A further aim was to see whether psychotic patients could be analysed without departures from the essentials of psychoanalytic technique. As in the case of Klein's analysis of children, the analysis of psychotic patients threw up new material and led to the development of new ideas and areas of interest.
