Abstract:
In this investigation of perceptual categorization (PC), .right-sided brain-damaged patients (RBD) were not impaired for PC of line drawings of animals relative to left-sided brain-damaged (LBD) patients, contrary to what was expected from previous work. Moreover, in both LBD and RBD patients PC performance was significantly associated with performance on a series of 6 sensory tests. These differed from conventional tests in that successive comparisons were required; and in 2 of the 6 tests gratings were discriminated.
