title: Visual organization ability in brain-damaged adults.
abstract: 49 brain-damaged patients (15 with left-hemisphere lesions, 19 with right-hemisphere lesions, and 15 with bilateral lesions) and 17 non-brain-damaged patients were administered the Hooper Visual Organization Test. Non-brain-damaged patients performed significantly better than the brain-damaged patients; however, the differences among the brain-damaged patients were not significant. Hooper Visual Organization Test seems valuable for identifying organicity but its usefulness for determining lateralization is limited. It is also suggested that both hemispheres form a close functional loop in subserving visual organization ability. A hypothetical diagram has been proposed to describe the functional dynamics of the visual synthesis ability measured by the Visual Organization Test.
