[Clinical psychological studies on adolescent and adult mongols (author's transl)]

A group of 20 mongol adolescents and adults with an average age of 19 years was strictly parallelized with a group of 20 brain-damaged adolescents and adults of other diagnostic groups with respect to age and intelligence level (average age 19 and average intelligence 50.65--52.90). The hypothesis of a possible deterioration of performance and personality was checked with the following battery of tests: Hamburg-Wechsler intelligence test for adults, the motoricity test according to Walther and the Rorschach experiment. The average difference in the sub-tests of HAWIE primarily emphasize the psycho-organic disturbance in visual-motor coordination, which is seen to a much greater extent in mongols than in non-mongols. The significant difference in completing pictures indicates an intensification of psycho-organicity. In agreement with the observations of WUNDERLICH, the psychomotoricity of the mongols is significantly slower and less adroit than the psychomotoricity of non-mongol oligophrenias. Non-significant differences in the psycho-organic sign (P%, F+%) in disfavor the mongols were seen in the Rorschach experiment. Factorial analysis distinguished the two groups very clearly. In the three most important factors, the mongol group showed stronger signs of psycho-organicity and weak mental performance associated with an intensified neuroticism factor compared with the brain-damage oligophrenia group of other diagnostic origin.
