Twenty sighted and twenty blind adults, 19 to 66 years of age, participated in tests of olfactory sensitivity to n-butyl alcohol and of identification of 80 everyday odors. The blind had poorer absolute sensitivity, but outperformed the sighted at identification. Age proved an important factor in the comparison; more than half the variance in identification within each group was ascribable to an age-related decline.
20名19至66岁有视力的成年人和20名盲人成年人参与了对正丁醇的嗅觉敏感度测试以及对80种日常气味的识别测试。盲人的绝对敏感度较低，但在气味识别方面表现优于有视力的人。在比较中，年龄被证明是一个重要因素；每组内超过一半的识别差异可归因于与年龄相关的下降。
