[Behavior therapy. Bases and criticism].
Our first concern is a general characterization of behaviour therapy. It cannot be produced by means of the description of its methods and techniques, since it includes a wide gamut of them, ranging from systematic desensitization to assertive training and aversive conditioning. It is necessary then to resort to the theoretical basis common to the different methods and techniques. The reciprocal inhibition principle, as stated by John Wolpe, is likely to provide a sound starting point. To Wolpe's mind, a neurosis is an anxiety response deeply rooted through conditioning. Most behaviour therapists share this conception. The therapist task is, according to it, to unchain the circuit between anxiety producing stimulus and neurotic responses. In order to achieve the disjunction, an antagonistic response is used, that reciprocally inhibits the anxiety response. Systematic desensitization based on relation is a typical application of the reciprocal inhibition principle. Nevertheless, other usual techniques, such as negative practice (used by Yates for the treatment of tics) or Skinner's operant conditioning are not based on that principle. A wider basis is thus required. Behaviour therapists claim that the theoretical basis is to be found in learning theory laws. The reciprocal inhibition principle is the counterpart of the counter-conditioning law, the negative practice principle is similar to the extinction law, and so on. However, there is not one single learning theory, but several ones, mutually contradictory. And they are not fit to provide the needed theoretical basis. That disagreement can be overcome looking for the common principle of all learning laws, namely, that the need is to create definite circuits that can operate in front of adequate stimulus. Still another set of criticisms to behaviour therapy comes from dynamic psychology and psychoanalysis. The fact is stressed that suppressing symptoms does not modify structural maladjustments. Behavior therapists acknowledge their treatments are kept at symptom level, but they claim it is the right approach, since the symptom is the neurosis, according to their conceptions.
