我们测试了大五人格特质的个体差异及其在生命的第九个十年中的变化与认知功能、身体健康和日常功能的水平和变化之间的关联。除了人格特质的平均水平变化外，81岁至87岁之间的变化率存在显着的个体差异。大五人格特质的变化并没有很强的相关性，这表明对人格变化的共同影响很小。79岁时智商较低，预示着智力较低，外向性较高，从81岁到87岁，责任心下降更多。此外，身体健康的下降与尽责性的下降有关。(C)2012 Elsevier Inc. All rights reserved.
We tested the associations between individual differences in the Big Five personality traits and their changes over the ninth decade of life and levels of and changes in cognitive functioning, physical fitness, and everyday functioning. Besides mean-level changes in personality traits, there were significant individual differences in their rates of change between ages 81 and 87. The changes in the Big Five traits were not strongly intercorrelated, suggesting little common influence on personality change. Lower IQ at age 79 predicted lower Intellect and higher Extraversion, and more decline in Conscientiousness from ages 81 to 87. Also, decreases in physical fitness were associated with declines in Conscientiousness. (C) 2012 Elsevier Inc. All rights reserved.
