潜在差异得分模型（例如，McArdle & Hamagami，2001）扩展到包括从先前的变化到后续变化的影响。潜在差异分数的这种扩展允许测试假设，其中最近的变化与最近的水平相反，是后续变化的主要预测因素。这些模型被应用到二元纵向数据收集的一部分，巴尔的摩纵向研究老化的记忆性能，测量的加州口头学习测试，和侧脑室的大小，测量的结构MRI。结果表明，侧脑室大小的最近增加是60岁至90岁记忆能力随后下降的主要指标。
Latent difference score models (e.g., McArdle & Hamagami, 2001) are extended to include effects from prior changes to subsequent changes. This extension of latent difference scores allows for testing hypotheses where recent changes, as opposed to recent levels, are a primary predictor of subsequent changes. These models are applied to bivariate longitudinal data collected as part of the Baltimore Longitudinal Study of Aging on memory performance, measured by the California Verbal Learning Test, and lateral ventricle size, measured by structural MRIs. Results indicate that recent increases in the lateral ventricle size were a leading indicator of subsequent declines in memory performance from age 60 to 90.
