Although research on personality and behavioral genetics has focused on the continuity of traits, both fields and their interface will profit from the consideration of trait change. In this article we review personality research on age differences in heritability and propose the counterintuitive hypothesis that, when developmental changes in heritability are found, heritability tends to increase. We also focus on behavioral genetic analyses of long-term developmental change. Research to date suggests that genetic involvement in adult personality change is slight whereas personality change in childhood is governed substantially be genetic factors. Finally, we consider a new topic, genetic influence on short-term change in personality.
尽管人格与行为遗传学的研究一直聚焦于特质的连续性，但这两个领域及其交叉领域都将从对特质变化的考量中受益。在本文中，我们回顾了关于遗传力年龄差异的人格研究，并提出了一个与直觉相悖的假设：当发现遗传力的发育变化时，遗传力往往会增加。我们还专注于长期发育变化的行为遗传学分析。迄今为止的研究表明，基因对成人人格变化的影响很小，而儿童期的人格变化在很大程度上受遗传因素支配。最后，我们考虑一个新的话题，即基因对人格短期变化的影响。
