[A testpsychological contribution to the etiology of autism (author's transl)]

The results of two psychological experiments (WURST 1976a,b) with a group of ASPERGER autists and KANNER autists and a parallel group considering age and intelligence show, that neither the belief, autism appears as a possible consequence of a psychoorganic syndrom nor the assumption that autistic behaviour is caused by a perception defect, can be proved with testpsychological methods. However, it seems, that KANNERS point of view, referring to autism as an inborn disturbance of the emotional contact influenced also by negative environment comes closest to the problem.
