Visual acuity and contrast sensitivity are two visual domains affected by normal aging; however, the potential impact of well-documented changes in these abilities on neuropsychological assessment is relatively unstudied. The current study examined the relationship between these abilities and neuropsychological performance in a healthy, community-based elderly sample. Fifty-one individuals (Age: M = 79.6) were assessed for visual acuity and visual contrast sensitivity, and received a brief neuropsychological battery. Results indicated contrast sensitivity was significantly related to neuropsychological performance on visually based measures, but not auditory measures. Visual acuity was only weakly related to neuropsychological performance. Clinical implications for assessment of elderly individuals are discussed.
视力和对比敏感度是受正常衰老影响的两个视觉领域；然而，这些能力中已被充分记录的变化对神经心理学评估的潜在影响相对较少被研究。当前的研究在一个基于社区的健康老年样本中考察了这些能力与神经心理学表现之间的关系。对51名个体（年龄：M = 79.6）进行了视力和视觉对比敏感度评估，并接受了一套简短的神经心理学测试。结果表明，对比敏感度与基于视觉的测量指标上的神经心理学表现显著相关，但与听觉测量指标无关。视力与神经心理学表现仅存在微弱关联。文中讨论了对老年个体评估的临床意义。
