Thirty-five right brain-damaged (RBD) stroke patients, enrolled in active rehabilitation programs, participated in this study. Patients were selected on the basis of their evidenced deficits in performing complex visuo-cognitive tasks and the absence of overt evidence of unilateral visual-spatial neglect. Seventeen of the 35 patients were randomly chosen to receive a training program (lasting approximately 1 month) designed to establish a systematic strategy of organizing complex visual material. The remaining 18 patients were re-examined after 1 month, and served as controls. The design of the treatment program was based on the hypothesis that nonneglected RBD patients fail to appreciate and synthesize elements of complex visual material due to a breakdown in compensation for a persistent lateral bias in visual-spatial attention. Upon posttesting, it was found that those patients who received training exhibited significantly improved performance, as compared to controls, on a subgroup of visuo-cognitive tasks. These results are discussed in terms of: (1) offering indirect support for the argument that pathological asymmetries in attention play a significant role in the failure of RBD patients on many visuo-cognitive tasks; and, (2) offering a basis for extending the treatment of perceptual problems in RBD patients.
35名参加积极康复计划的右脑损伤（RBD）中风患者参与了本研究。患者的入选依据是他们在执行复杂视觉认知任务时存在明显缺陷，且没有明显的单侧视觉空间忽视迹象。35名患者中有17名被随机挑选出来接受一个培训项目（持续约1个月），该项目旨在建立一种组织复杂视觉材料的系统策略。其余18名患者在1个月后接受重新检查，并作为对照组。治疗方案的设计基于这样一种假设，即未被忽视的RBD患者由于在视觉空间注意力方面持续存在的侧向偏差的补偿机制失灵，无法理解和综合复杂视觉材料的元素。在进行后测时发现，与对照组相比，接受培训的患者在一组视觉认知任务中的表现有显著改善。这些结果从以下方面进行了讨论：（1）为注意力的病理性不对称在RBD患者在许多视觉认知任务中失败方面起重要作用这一观点提供了间接支持；（2）为扩展RBD患者感知问题的治疗提供了基础。
