路易斯维尔双胞胎研究包括. apprx。500对双胞胎和他们的兄弟姐妹参加了一项从婴儿期开始到青春期的心理发展纵向研究。智力的个体差异随着学龄的增长而逐渐稳定下来，每个孩子的智力发展都遵循着一种独特的模式，即智力发展的爆发和滞后。同卵双胞胎随着年龄的增长而变得越来越一致，并且在发育趋势上彼此紧密匹配。异卵双生子回归到一个中等水平的一致性，与兄弟姐妹和父母-子女集发现。进行全面的家庭评估，以确定家庭/家庭变量，有助于心理发展。总体结果表明，智力的增长有一个强大的发展推动力，这主要是由内在的遗传基础计划指导的。家庭和家庭的质量特征对后代智商的预测有显著的作用。这些结果在Waddington的发育模型的背景下进行解释，并调查了神经生物学和遗传学的一些最新进展，以探讨其对发育行为遗传学的影响。
The Louisville Twin Study includes .apprx. 500 pairs of twins and their siblings who have participated in a longitudinal study of mental development, beginning in infancy and extending to adolescence. Individual differences in intelligence progessively stabilized by school age, and each child followed a distinctive pattern of spurts and lags in mental development. Monozygotic twins became increasingly concordant over ages and matched each other closely for development trends. Dizygotic twins regressed to an intermediate level of concordance, comparable with that found for siblings and parent-offspring sets. A comprehensive home assessment was performed to identify the home/family variables that contributed to mental development. The overall results pointed to a strong developmental thrust in the growth of intelligence, which was principally guided by an intrinsic genetic ground plan. Qualitative features of home and family did add significantly to prediction of offspring IQ. The results are interpreted in the context of Waddington''s developmental model, and some recent advances in neurobiology and genetics are surveyed for their implications for developmental behavior genetics.
