[The schizophrenic world view--psychopathologic aspects of ontogenetic regression]

If reality is represented in the neuronal structures of mans central nervous system, any disturbance of cognitive functions must necessarily change mans concept of his reality. The hypothesis presented in this study is that an ontogenetic regression of cognitive processes to an "actional-concretistic" level of "representations" is attached to a reduction of the "sphere of action" (by analogy with the territorial zones in ethology) to the immediate "individual area". The main features of the psychopathology of schizophrenic experience and behavior such as the concrete and the overinclusive thinking, the impairment of selective attention, hyper- and hyposensitivity, the ambivalence concerning separatism (minus) and egocentrism (plus), ideas of reference and the disturbance of identity are seen under this new aspect.
