We administered to 80 optimally healthy subjects, 30-80 years old, the Boston Naming Test, a test of confrontation naming. Results indicated that naming ability remains fairly stable across the adult life span until individuals are in their 70s, at which point there is a significant decline in performance (p less than or equal to .0001). Semantic errors (i.e., circumlocutions, semantically related associates, and nominalizations) and perceptual errors increase with age. Lexical errors (i.e., phonologically related real words and phonologically related nonwords) do not increase with age. Results of multiple regressions that included other neuropsychological variables indicate that estimated IQ, but not new learning ability, predicts a subject's naming score.
我们对80名年龄在30至80岁之间的健康状况最佳的受试者进行了波士顿命名测试，这是一项视觉命名测试。结果表明，在70多岁之前，命名能力在成年期内保持相当稳定，而到了70多岁时，表现会出现显著下降（p小于或等于0.0001）。语义错误（即迂回表达、语义相关的联想词和名词化）以及感知错误会随着年龄增长而增加。词汇错误（即语音相关的实词和语音相关的非词）不会随着年龄增长而增加。包含其他神经心理学变量的多元回归结果表明，估计智商而非新的学习能力能够预测受试者的命名分数。
