研究了注意力的变化以及从中年开始的变化率的性别差异。在4个年龄组（40岁、50岁、60岁和70岁）的10年随访中，对数字取消测试（D-CAT 1和D-CAT 3条件，分别涉及低和高认知负荷）评分和单独计算的下降率（DR）进行了检查。从50岁到70岁，两种D-CAT条件下的表现都随着年龄的增长而下降，而40岁和50岁之间没有差异，在D-CAT 3上，40岁和50岁组中表现出性别差异（女性表现出优势）。在D-CAT 1条件下，DR从40 s到50 s保持稳定，但从50 s到60 s增加，然后保持不变。在D-CAT 3条件下，即使在70年代之后，DR也变得更大。从中年开始，DR在男性和女性之间没有差异。虽然DR没有显示出性别差异，但D-CAT表现却显示出性别差异，男性在40岁时的能力要低20%。我们认为，中年后注意力表现的具体下降的数据可以用来减少老年人日常生活中遇到的事故。
Age-related changes in attention ability and differences by gender in the rates of change from middle age were investigated. Digit Cancellation Test (D-CAT1 and D-CAT3 conditions, which involve low and high cognitive load, respectively) scores and individually calculated decline rates (DRs) in 10-year follow-up among four age groups (40s, 50s, 60s, and 70s) were examined. Performance in both D-CAT conditions declined with increasing age from the 50s to the 70s, whereas there was no difference between the 40s and 50s, and a gender difference (with the women showing an advantage) was demonstrated in the 40s and 50s groups on the D-CAT3. In the D-CAT1 condition, the DR remained stable from the 40s to the 50s but increased from the 50s and to the 60s and then remained the same. In the D-CAT3 condition, the DR became larger even after the 70s. The DRs did not differ between men and women from middle age onward. Although DRs showed no gender difference, D-CAT performance showed a gender difference, with men being about 20% less capable by the age of 40. We suggest that data showing concrete declines in attentional performance after middle age may be used to reduce accidents encountered in the daily life of older adults.
