[Psychological test differentiation of neurotic and organically induced performance disorders].

Current methods of diagnosing psychological performance, which are primarily status-oriented, are inadequate to permit satisfactory differentiation between brain-organically and neurotically induced performance disturbances. We therefore attempted to contribute to the solution of this problem by adopting a new psychodiagnostic approach (measurement of intraindividual variability) and using multi-point measurements with the aid of attentiveness tests. The fact that 80 to 90% of 254 neurotic and brain-damaged subjects could be correctly diagnosed in the way indicates that the new approach to performance diagnosis is suitable for clinical use.
