Performance on a random-letter stereoscopic task has been reported to be affected by right but not left cerebral disease. Subsequent studies employing a conventional stereoacuity test have challenged these results and proposed that dementia may be the primary determinant of impaired stereopsis in the patients with brain disease. The latter investigators have failed to distinguish between local and global stereopsis. The present study confirms the original findings, rules out dementia as a potential artifact, and attempts to reconcile the conflicting series of reports.
据报道，随机字母立体视觉任务的表现会受到右脑疾病而非左脑疾病的影响。随后采用传统立体视敏度测试的研究对这些结果提出了质疑，并提出痴呆可能是脑部疾病患者立体视觉受损的主要决定因素。后一组研究人员未能区分局部和整体立体视觉。本研究证实了最初的发现，排除了痴呆作为潜在假象的可能性，并试图调和相互矛盾的一系列报告。
