The validity of Bucur and Madden's (2010) proposal that an age-related decline is particularly pronounced in executive function measures rather than in elementary perceptual speed measures was examined via the Yakumo Study longitudinal database. Their proposal suggests that cognitive load differentially affects cognitive abilities in older adults. To address their proposal, linear regression coefficients of 104 participants were calculated individually for the digit cancellation task 1 (D-CAT1), where participants search for a given single digit, and the D-CAT3, where they search for 3 digits simultaneously. Therefore, it can be conjectured that the D-CAT1 represents primarily elementary perceptual speed and low-visual search load task. whereas the D-CAT3 represents primarily executive function and high-visual search load task. Regression coefficients from age 65 to 75 for the D-CAT3 showed a significantly steeper decline than that for the D-CAT1, and a large number of participants showed this tendency. These results support the proposal by Brcur and Madden (2010) and suggest that the degree of cognitive load affects age-related cognitive decline.

视觉搜索负荷对与年龄相关的认知衰退的影响：来自八云纵向研究的证据。

Bucur and Madden（2010）的建议是通过Yakumo研究纵向数据库检查了与年龄相关的下降在执行功能指标中而不是在基本知觉速度指标中特别明显的建议。他们的建议表明，认知负荷差异影响老年人的认知能力。为了解决他们的建议，分别为数字消除任务1（D-CAT1）和D-CAT3计算了104位参与者的线性回归系数，其中参与者搜索给定的一位数字，而D-CAT3则同时搜索3位数字。因此，可以推测D-CAT1主要代表基本的感知速度和低视觉搜索负载任务。而D-CAT3主要代表执行功能和高视觉搜索负荷任务。D-CAT3从65岁到75岁的回归系数显示出比D-CAT1显着下降的趋势，并且许多参与者都表现出这种趋势。这些结果支持了Brcur和Madden（2010）的建议，并表明认知负荷的程度会影响与年龄相关的认知能力下降。
