Abstract
This research, conducted on 38 male psychiatric inpatients, replicated previous findings that inability to “shift” conceptual attitude on the Weigl Color-Form Sorting Test is consistent with indices often associated with cortical dysfunction, such as Bender-Gestalt recall, WAIS Similarities subtest scores, and age. Regression analysis yielded a multiple R of .52, with ability to shift predictable from the difference between WAIS Verbal IQ and subjects' age. The relationship between the Weigl and the Hooper approached significance, but that between the Weigl and Trail Making did not. The Weigl might serve as a non-verbal instrument to assess cortical dysfunction where inability to “shift” appears to tap a dysfunction in symbolic reasoning rather than spatial reasoning.
