为了进一步从个体生命周期的角度研究稳定与变化的问题，我们研究了成年期的人格特质轨迹。在规范衰老研究中，对1600多名男性（最初年龄在43-91岁）的外向性和神经质的生长曲线进行了估计，随访时间超过12年。我们发现，这两种特征的个体内部变化存在显著差异，外向性和神经质的个体变化轨迹也不同。外向性的总体轨迹最好用线性模型来定义，但神经质的特征是随着年龄的增长而二次下降。然后，我们考虑了几个变量作为这些总体轨迹周围个体差异的预测因子。出生队列、婚姻或再婚、配偶死亡和记忆抱怨都是显著的预测因素，解释了人格特质改变水平和速度的差异。这些发现表明，性格轨迹有很大的可变性，其中一些可变性可以通过出生队列和年龄分级的生活事件来解释。
To advance an intraindividual life-span approach to the issue of stability and change, we studied personality trait trajectories in adulthood. Growth curves for extraversion and neuroticism were estimated for over 1,600 men (initially aged 43-91) in the Normative Aging Study, who were followed over 12 years. We found significant individual differences in intraindividual change for both traits, as well as different trajectories for extraversion and neuroticism. The overall extraversion trajectory was best defined by a linear model, but neuroticism was characterized by quadratic decline with age. We then considered several variables as predictors of individual differences around these overall trajectories. Birth cohort, marriage or remarriage, death of spouse, and memory complaints were all significant predictors, explaining variability in both level and rate of personality trait change. These findings suggest that there is a good deal of variability in personality trajectories, and that some of this variability can be explained by birth cohort as well as by age-graded life events.
