本研究探讨了言语能力认知老化的性别差异。为了研究字母流畅性（LFT）和语义流畅性（SFT）测试的发展变化，40岁以上的健康女性224名和男性139名参加了这项研究。结果表明，40年代和50年代的男女成绩基本保持在同一水平上，但70年代以后的男女成绩下降趋势并不平行。对于LFT，男性从50岁到70岁急剧下降，而女性从50岁到80岁逐渐下降。对于SFT，男性从50岁到70岁表现出急剧下降，70岁后保持在类似的水平，而女性从50岁到70岁没有表现出急剧下降，70岁的表现水平与80岁相同。
This study examined the sex difference in cognitive aging for verbal abilities. To examine developmental changes on Letter Fluency (LFT) and Semantic Fluency (SFT) tests, healthy 224 women and 139 men over 40 years old participated in this study. The results showed that performance of both sex in the 40’s and 50’s remained at the same level, but the performance declining for the LFT and the SFT after the 70’s were not parallel. For the LFT, men showed a steep decline from 50’s to 70’s, whereas women showed a gradual decline from 50’s to 80’s. For the SFT, men showed a sharp decline from 50’s to 70’s and remained at a similar level after the 70’s, whereas women did not show a steep performance decline from their 50’s to 70’s and their performance level in 70’s was the same as in 80’s.
