An attempt was made to determine whether the Reltan-Halstead Organic Test Battery separates neuropsychiatric hospital organics from schizophrenics. The battery was administered to 25 schizophrenics and 2$ cerebral-lesion organics at each of 2 chronicity levels. Only 1 of the 24 diagnosis/Diagnosis X Chronicity effects used to evaluate the data was significant at the .05 level, indicating that actuarial application of Reitan-Halstead scores is of no practical value in the separation of the 2 groups. To determine whether expert clinicians might improve upon the actuarial results, protocols of 24 schizophrenics and 24 organics were sent to 8 Reitan-Halstead experts who were instructed to separate them into brain-damaged and schizophrenic diagnostic groups. The mean number of correct classifications, 25.5 out of 48, suggested that clinical judgment added nothing to actuarial prediction in this case.

Previous research has suggested that content analysis of the Rorschach may be a useful tool in diagnosing homosexuality. This study compared five Rorschach sign approaches (Due & Wright, Fine, Schafer, Ulett, and Wheeler) within a three-group design employing heterosexuals, sex-role disturbed, and homosexuals. The results indicated that all five sets of signs were able to differentiate the homosexual and heterosexual groups, but only the Schafer and Ulett signs discriminated between the sex-role disturbed and homosexual groups. Step-wise discriminant analyses were computed to determine what combinations of signs could most accurately differentiate the three groups.

Earlier research has indicated that many of the common “brain-damage” tests do not discriminate organic from schizophrenic NP patients. In the present paper the abilities of Reitan's six sensory-perceptual tests to separate these two groups were tested. The results for five of the tests—Tactile Finger Recognition (Finger Agnosia), Finger-tip Writing, Tactile Form Recognition, Tactile Sensory Imperception, and Visual Sensory Imperception—were unencouraging. However, the absolute right-left difference scores for Auditory Sensory Imperception showed some promise and total number of Auditory Double stimulation errors also separated recently admitted organics from recently admitted schizophrenics. Implications of the findings are briefly discussed.
