[Cognitive disturbances in schizophrenia - experimental psychological examination and explanation in the frame of cognitive information processing].

The concern of the paper is, by using the example of schizophrenia, to show in a survey that it is possible and necessary to base the examination of cognitive disturbances and their exaplanation on the methodological concept of information processing. Departing from the stage reached in cognition-psychological schizophrenia research, a survey is given of such studies of cognitive disturbances in schizophrenia that are based on general psychological concepts of cognitive information processing. The approach to an identification of the defect within the frame of a model of the cognitive information processing is explained by two examples (performance of recognition, reproduction deficit).
