Behaviorism see psychological disorders as the result of maladaptive learning, as people are born tabula rasa (a blank slate). They do not assume that sets of symptoms reflect single underlying causes.
Classical conditioning involves learning by association and is usually the cause of most phobias. Operant conditioning involves learning by reinforcement (e.g. rewards) and punishment, and can explain abnormal behavior should as eating disorders.Consequently, if a behavior is learnt, it can also be unlearned.
Behavioral therapies are based on the theory of classical conditioning. The premise is that all behavior is learned; faulty learning (i.e. conditioning) is the cause of abnormal behavior. Therefore the individual has to learn the correct or acceptable behavior.
An important feature of behavioral therapy is its focus on current problems and behavior, and on attempts to remove behavior the patient finds troublesome. This contrasts greatly with psychodynamic therapy (re: Freud), where the focus is much more on trying to uncover unresolved conflicts from childhood (i.e. the cause of abnormal behavior). Examples of behavior therapy include:
- Systematic Desensitization
- Aversion Therapy (see below)
The theory of classical conditioning suggests a response is learned and repeated through immediate association. behavioral therapies based on classical conditioning aim to break the association between stimulus and undesired response (e.g. phobia, additional etc.).
Aversion therapy is used when there are stimulus situations and associated behavior patterns that are attractive to the client, but which the therapist and the client both regard as undesirable. For example, alcoholics enjoy going to pubs and consuming large amounts of alcohol
Aversion therapy involves associating such stimuli and behavior with a very unpleasant unconditioned stimulus, such as an electric shock.
The client thus learns to associate the undesirable behavior with the electric shock, and a link is formed between the undesirable behavior and the reflex response to an electric shock.
In the case of alcoholism, what is often done is to require the client to take a sip of alcohol while under the effect of a nausea-inducing drug. Sipping the drink is followed almost at once by vomiting. In future the smell of alcohol produces a memory of vomiting and should stop the patient wanting a drink.
More controversially, aversion therapy has been used to "cure" homosexuals by electrocuting them if they become aroused to specific stimuli.
Evaluation of Therapy
Apart from ethical considerations, there are two other issues relating to the use of aversion therapy.
First, it is not very clear how the shocks or drugs have their effects. It may be that they make the previously attractive stimulus (e.g. sight/smell/taste of alcohol) aversive, or it may be that they inhibit (i.e. reduce) the behavior of drinking.
Second, there are doubts about the long-term effectiveness of aversion therapy. It can have dramatic effects in the therapist’s office. However, it is often much less effective in the outside world, where no nausea-inducing drug has been taken and it is obvious that no shocks will be given.
Also, relapse rates are very high the success of the therapy depends of whether the patient can avoid the stimulus they have been conditioned against. Aversion therapy also has many ethical problems.
