Has the cataphasic form of schizophrenia increased in modern times?

According to our investigations the incidence of cataphasia, which is a subtype of schizophrenia, has become more common in the last years and on average, has started earlier in life. As the central disorder of this illness concerns thinking perhaps there exists a relation of our finding to the rapid modern development of techniques, insofar as the cognitive function is overstrained in childhood and adolescence, when the nervous system has not matured yet. Introverted individuals seem to be at a particular risk. However, it must not be disregarded that cataphasia is an inherited illness which cannot be caused by external influences, but can only be promoted in its manifestation.     

Differential diagnosis of endogenous psychoses in relation to a symptom catalog

The paper introduces a catalog of symptoms to promote in the field of endogenous psychoses differentiated diagnosis, at the same time constituting a prognosis. Symptoms should be more minutely differentiated than is customary in psychiatric questionnaires. Manic-depressive disorders and purely phasal psychoses are distinguished solely in the clinical evaluation. Thus benign cycloid psychoses can be distinguished from malignant unsystematic schizophrenia.     

Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.     

Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.     

Hereditary and psychosocial causes of schizophrenia

On the basis of the examination of patients with endogenic psychosis, indications were obtained that there are forms that mainly develop on a hereditary basis, and forms determined by psychosocial causes. In unsystematic schizophrenia the chief factors are hereditary, above all in periodic catatonia. On the other hand, there are a few indications of a hereditary genesis in systematic schizophrenia although it is just these forms that are distinguished by the severity of their course. By studying twins, cases of schizophrenia in infancy, and the circumstances of brothers and sisters, strong indications of psychosocial causes of systematic schizophrenia were found. Lack of contacts in the course of development appears to the determing factor. In motility psychosis, one of the cycloid psychoses, indications were found that excessive encouragement by other children can be a cause of overstrain and thus may be detrimental. The conclusions drawn are based on concrete findings obtained in a total of 1,114 cases and are for the most part statistically significant.
