The maze test and clinical psychology

"In continuous use since 1915, the Porteus Maze test retains its original character and is easily the most durable test in clinical practice today. Yet in the last fifteen years new and striking proofs of its validity have been forthcoming. It is now accepted as the most sensitive measure of brain damage available. The most recent follow-up of Columbia-Greystone patients (1958) showed that 94 per cent of patients who suffered superior cortical topectomies exhibited marked Maze test impairment. No other test scale reflects such consistent losses following all types of psychosurgery, vitamin B deficiency, or use of a tranquilizing drug. Thus the Maze is by far the most sensitive indicator of induced deficits. It can therefore be described as a psychosomatic test. For 45 years it has proved valuable in the diagnosis of mental deficiency and the qualitative scoring reveals reliable differences between delinquents and non-delinquents. But the most amazing new development concerns the test's projective-expressive aspects, the execution of which makes it possible to match a single individual repetition in 90 per cent of cases. Upon this is based a self-consistency or flexibility score. This new volume describes both the Original and Extension series, discusses their theoretical framework, presents simplified test quotient tables, and sets forth concise rules for application and scoring of the tests"--Jacket.
