Our concept of the functional-psychotic mental deterioration of schizophrenia approximately characterizes the same point of view as Kraepelin's terminus "Dementia praecox". The first result of our psychological examination on 225 schizophrenic persons with defect psychotic symptoms was the statement of the deficit in achievement between the former school education (average IQ of the school-type) and the results of examination of intelligence during our research. The functional-psychotic mental deterioration as well appears as a decrease of memory and psychomotoric speed deficiency, furthermore as mental deconcentration and increase of psychoorganic signs in the Rorschach-Test. The psychometric results of this research were statisticly significant.
我们关于精神分裂症功能性精神病性精神衰退的概念与克雷佩林的术语“早发性痴呆”大致体现了相同的观点。我们对225名有缺陷精神病症状的精神分裂症患者进行心理检查的首个结果是，发现他们之前的学校教育水平（学校类型的平均智商）与我们研究期间的智力测验结果之间存在成绩缺陷。功能性精神病性精神衰退还表现为记忆力下降、精神运动速度不足，此外在罗夏测验中还表现为注意力不集中和心理器质性症状增加。这项研究的心理测量结果具有统计学意义。
