– Aversion therapy attempts to associate an unpleasant CR, such as nausea, with stimuli associated with unwanted behavior, such as the smell of alcohol.
– Systematic desensitization attempts to elminate an unwanted CR, such as anxiety, by gradually exposing the patient to associated CS’s (e.g. angry words) in a relaxing situation.
– Flooding attempts to eliminate an unwanted CR through massive exposure of the associated CS, as in extinction.
Such therapies and treatments using classical conditioning differ from those using operant conditioning.
