The authors use a simple test, following the concepts of gestalt psychology: the writing of the alphabet on the blackboard, spontaneously or upon dictation, under varied conditions. The reactions and attitudes of the patient performing the test and his reflections upon the other members of the group afford insight into certain behavior patterns and present opportunities to administer effective treatment on the spot. The situation presents emotional reactions to the group rather than to the person of the therapist. This may promote a subsequent readjustment to society at large. The writers recognize the value of biographical data but it is not considered essential in this approach in which the patients' present functioning and future improvement is considered more important than his past mistakes. This is in contrast, the writers state, to the recommendations of other authors who employ psychoanalytic concepts in group psychotherapy. However, individual interviews and the method described here may well supplement each other.
