ABSTRACT
The effective control of behaviour was limited to the animal laboratory. The extension of this control to human behaviour was made when O. Lindsley successfully adapted the methodology of operant conditioning to the study of psychotic behaviour. What follows is a demonstration of behaviour techniques for the intensive individual treatment of psychotic behaviour. Specific pathological behaviour patterns of a single patient were treated by manipulating the patient's environment. The dining room was the only place where food was available and entrance to the dining room could be regulated. Water was freely available at a drinking fountain on the ward. None of the patients had ground passes or jobs outside the ward. The three types of behaviour include stealing food, hoarding, and excessive dressing. In order to modify the patient's behaviour systematically, each of these three types of behaviour was treated separately.
