SUMMARY
A preliminary study of 9 patients investigated initially on admission and retested after 8 weeks treatment with optimal doses of neuroleptics are presented. The tests employed were: Raven Progressive Matrices, GGWS Object Sorting Test and Rorschach. Statistically significant score changes were registered on the two latter tests. The importance of the tests' structural complexity in so far as it concerns activation of cognitive disturbances is brought out. In addition it is suggested that disturbances in respectively perceptual organization and thought are related to psychopathologies of dissimilar nature and resistance. Comprehensive evaluation of changes in personality functioning from Rorschach responses indicated qualitatively different directions of change which could be related to the initial pathology.
