ABSTRACT
The importance of Donald R. Peterson and Perry London's work is that it leaves open the possibility of a synthesis of the developments in behavioural therapy with the "dynamic" therapies which depend on comprehension, awareness, cognition, hindsight, foresight, and insight. Hypnotic suggestion was elected as the means of changing expectancies regarding pain of sphincter pressure and the act of elimination itself. The therapeutic strategy which was planned on the basis of the foregoing analysis consisted of generation of insight to facilitate the initiation of the eliminative sequence, and reinforcement of the adaptive, that is, "target" behaviour, upon its occurrence. Modern behaviour therapy is enjoying a surge of popularity unequalled by any treatment innovation since Elisha Perkins applied tractors to hysterics. Behaviour therapy is efficient and dependable. The omission is most conspicuous in systems evolving from the work of Skinner and his disciples, but it also holds, in lesser extent, for most other versions of behaviour therapy.
