This paper presents the results of comparing the validity of the Rorschach test with the. validities of individual neurologic procedures in distinguishing between patients with and those without lesions of the central nervous system.

In the process of collecting data on the cross validation of the Rorschach test and its applicability to central nervous system pathology reported in a previous paper,1 we also obtained data on standard neurologic procedures. The method employed to obtain criterion groups in the cross-validation study was designed so as to provide samples as representative as possible of everyday diagnostic cases in hospital neurology. The method was suggested by Piotrowski4 about 15 years ago:

The best control for the cerebral group would seem to be one composed of patients who had been seriously considered to have cerebral lesions and in whom the possibility of cerebral lesions was excluded after a longer period of observation.
