ABSTRACT
The historical lens used in this book has already revealed that the search for Rorschach indices of schizophrenia is as old as the Rorschach Test itself. In earlier chapters, however, we saw how this search was marred by conceptual confusion and diagnostic misunderstanding. In the past, thought disorder was considered to be a monolithic, noncontinuous construct, synonymous with schizophrenia. A thought disorder was either present or absent; and the existence of a disturbance in thinking was assumed to be diagnostic of a schizophrenic illness (a mild form of diagnostic paralogia).
