采用分类交配条件路径表示的遗传和环境传播的多元路径模型拟合了来自科罗拉多收养项目的特定认知能力数据，并使用最大似然估计程序进行了评估。与先前对较小数据集的分析结果一致，表明认知变量之间存在显著的遗传共变，并发现了一般遗传因素的证据。然而，文化传播参数不显著，测量之间的环境相关性相对较小。
A multivariate path model of genetic and environmental transmission employing a conditional path representation of assortative mating was fitted to specific cognitive abilities data from the Colorado Adoption Project and evaluated using a maximum-likelihood estimation procedure. In agreement with results obtained from a previous analysis of a smaller data set, significant genetic covariation among the cognitive variables was indicated and evidence for a general genetic factor was found. However, cultural transmission parameters are nonsignificant and environmental correlations among the measures are relatively small.
