Sage Journals: Discover world-class research

Abstract

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.
