摘要：

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-CAT 1), where participants search for a given single digit, and the D-CAT 3, where they search for 3 digits simultaneously. Therefore, it can be conjectured that the D-CAT 1 represents primarily elementary perceptual speed and low-visual search load task, whereas the D-CAT 3 represents primarily executive function and high-visual search load task. Regression coefficients from age 65 to 75 for the D-CAT 3 showed a significantly steeper decline than that for the D-CAT 1, and a large number of participants showed this tendency. These results support the proposal by Bucur and Madden (2010) and suggest that the degree of cognitive load affects age-related cognitive decline.
