在有左右半球病变的患者和没有脑部疾病病史或证据的对照组患者中，评估了短暂暴露的单点和成对点的定位的准确性。右脑受损者表现受损的频率明显较高。左侧大脑半球病变患者的表现与对照组相当。视野缺陷在右半球组与定位缺陷有关，而在左半球组与视野缺陷无关。失语障碍和年龄与学习成绩无关。本文还讨论了这一结果与以往单侧脑部疾病患者视觉定位研究的关系。
The accuracy of localization of briefly exposed single dots and pairs of dots was assessed in patients with lesions of the left and right hemispheres and in control patients without history or evidence of brain disease. A remarkably high frequency of impaired performance was found in the patients with right hemisphere lesions. The performance of the patients with left hemisphere lesions was comparable with that of the control patients. Visual field defect was associated with defective localization in the right hemisphere group but not in the left hemisphere group. Aphasic disorder and age were not related to performance level. The relationship of the findings to those of previous studies of visual localization in patients with unilateral brain disease is discussed.
