[New elements in behavior therapy of a case of dog phobia in an adolescent patient with Down's syndrome. A critical study of the method].

A review of the actual literature shows, that we have no reports of successful behavioral methods for the treatment of mentally retarded children with phobias. This study suggests a new way for treating a dog-phobia of a seventeen year old boy with Downsyndrom, using a special form of flooding by including the Premack-principle. Problems of desensitization and other special effects during therapy of these patients are discussed.
