Research on the clinical usefulness of the Rorschach: 2. The assessment of cerebral dysfunction

A review of research on the use of the Rorschach in the assessment of cerebral dysfunction indicated that the Rorschachs of patients with cerebral dysfunction do not manifest any characteristic response in terms of percentages, ratios, or any unique response to any one of the stimulus determinants of the blots (color, shading, the stimulus for movement). The patient with cerebral dysfunction does manifest a unique style of thinking; responses tend to be concrete, perseverative, and stereotypic. This finding is similar to that found with schizophrenics where research, summarized by Frank in 1990, also indicated no uniquely 'objective' response style but reflected a unique cognitive style. These two reviews taken together suggest that the better way to use Rorschach data in clinical work is as an opportunity to assess patients' thinking as opposed to the Rorschach being used as a psychometric device, yielding 'numbers.'
