Although compelling and insightful, the proposal by Uchiyama et al. largely neglects within-person change over time, arguably the central topic of interest within their framework. Longitudinal behavioural genetics modelling suggests that the heritability of trajectories is low, in contrast to high and increasing cross-sectional heritability across development. Better understanding of the mechanisms of trajectories remains a crucial outstanding challenge.
尽管 Uchiyama 等人的建议引人注目且富有见地,但很大程度上忽略了个体随时间的变化,而这正是他们研究框架中核心关注的话题。纵向行为遗传学模型表明,轨迹的遗传性较低,而在整个发展过程中,横截面遗传性则较高且呈上升趋势。更好地理解轨迹的机制仍然是一个至关重要的待解决的挑战。
