目前的调查比较了非痴呆识字和文盲老年人的神经心理测试表现。样本包括参与北方曼哈顿社区正常衰老和痴呆流行病学研究的参与者。所有参与者都被神经科医生诊断为非痴呆，并且没有帕金森病，中风或头部受伤的病史。识字水平由自我报告确定。MANOVA揭示了一个显着的整体效果，识字状况（识字与文盲）对神经心理测试的表现时，组匹配的教育年限。识字状况的整体效果仍然显着后，限制分析，没有正规教育的老人，并控制后的语言测试管理的影响。具体来说，文盲在命名、理解、言语抽象、定向、图形匹配和识别方面的得分较低。然而，测试的口头清单延迟回忆，非言语抽象，类别流畅性不受识字状况，这表明这些措施可以用来准确地检测认知能力下降文盲老人在这个样本。视觉空间信息组织的差异，缺乏以前的刺激，以及语言的逻辑功能的解释困难是可能的因素，有助于我们的研究结果。
The current investigation compared neuropsychological test performance among nondemented literate and illiterate elders. The sample included participants in an epidemiological study of normal aging and dementia in the Northern Manhattan community. All participants were diagnosed as nondemented by a neurologist, and did not have history of Parkinson's disease, stroke, or head injury. Literacy level was determined by self-report. MANOVAs revealed a significant overall effect for literacy status (literate vs. illiterate) on neuropsychological test performance when groups were matched on years of education. The overall effect of literacy status remained significant after restricting the analyses to elders with no formal education, and after controlling for the effects of language of test administration. Specifically, illiterates obtained lower scores on measures of naming, comprehension, verbal abstraction, orientation, and figure matching and recognition. However, tests of verbal list delayed recall, nonverbal abstraction, and category fluency were unaffected by literacy status, suggesting that these measures can be used to accurately detect cognitive decline among illiterate elders in this sample. Differences in organization of visuospatial information, lack of previous exposure to stimuli, and difficulties with interpretation of the logical functions of language are possible factors that contribute to our findings.
