The 60-item version of the Boston Naming Test (BNT) was administered to a group of 176 normal older adults in Middle Tennessee ranging in age from 60 to 93 years. Results are reported in five age groupings by gender and education. Although a few studies have previously examined the performance of the elderly on the BNT, the current study attempted to recruit individuals in proportion to the demographics of the regional population including gender, race, and, as much as possible, education and occupation. The results indicate that while age significantly affected confrontational naming ability, the interaction of age and education appeared to be a better predictor of performance. As with previous studies, more variability was found in higher age groups and in those with less education. Naming ability remained stable in the higher education group (> or = 12th grade) until 80 years, whereas those patients with less than a high school education demonstrated a decrement in naming ability at 70 years. Current results also revealed a gender bias for this population, with males scoring higher on 17 of 19 items where a significant difference existed.
对田纳西州中部176名年龄在60至93岁之间的正常老年人进行了60项版本的波士顿命名测试（BNT）。按性别和教育程度将结果报告为五个年龄组。尽管之前有一些研究考察了老年人在BNT上的表现，但当前研究试图按照该地区人口的人口统计学特征（包括性别、种族，并尽可能涵盖教育程度和职业）按比例招募个体。结果表明，虽然年龄显著影响对物命名能力，但年龄与教育程度的交互作用似乎是表现的更好预测指标。与之前的研究一样，在年龄较大的组和教育程度较低的组中发现了更多变异性。高等教育组（≥12年级）的命名能力在80岁之前保持稳定，而高中以下教育程度的患者在70岁时命名能力出现下降。当前结果还揭示了该人群存在性别偏见，在存在显著差异的19项中的17项上，男性得分更高。
