Two inpatients, one with a circumscribed phobia for dentists and dental offices and another who had been diagnosed as suffering from an anxiety neurosis, were treated with a flooding procedure. A simple flooding technique which dealt with only the symptom contingent cues was sufficient to change behavior in the former case, but for the relatively complex anxiety neurosis the more structured flooding technique, Implosive Therapy, was used. The case studies were considered demonstrative of the process of flooding as it applies to both a situation-specific and a non-situation-specific anxiety state. Some theoretical and semantic issues relative to therapy process were discussed. (Author)
