DESCRIPTION (provided by applicant): The primary objective of is to assess genetic and environmental influences on individual differences in behavioral development. The study includes 245 adoptive families, including biological parents, adoptive parents, and their children (probands and siblings), as well as 245 matched "control" (nonadoptive) families. The children are studied in their homes at ages 1, 2, 3, and 4; in the laboratory at 7, 12, and 16; and via telephone at 9, 10, 11, 13, 14 and 15. By the end of the current funding period we will have completed testing of adopted and non-adopted probands and their siblings through age 16. In addition, we have been testing a longitudinal sample of 385 twin pairs at the same ages. The proposed continuation of HD-10333 will complete the assessment of these twin pairs through age 16. The unique combination of the longitudinal adoption design and the longitudinal study of twins greatly strengthens the scope and power of inference regarding developmental processes, exploiting the advantages of each approach and minimizing their limitations. This final proposed continuation of HD-10333 will reap the harvest from this landmark study of child development, with important implications for education, mental health, and childrearing practices.

描述（由申请人提供）：IS的主要目的是评估遗传和环境对行为发展中个体差异的影响。该研究包括245个收养家庭，包括亲生父母，养父母和他们的孩子（概率和兄弟姐妹），以及245个匹配的“控制”（非辅助）家庭。在1、2、3和4岁时，对孩子们进行了研究。在7、12和16的实验室中；通过电话在9、10、11、13、14和15。到当前资金期结束时，我们将完成对16岁的被采用和未经补习的探针及其兄弟姐妹的测试。此外，我们还在同一年龄在同一年龄阶段测试385个双重纵向的纵向样本。拟议的HD-10333延续将在16岁时完成对这双对的评估。 纵向采用设计和双胞胎纵向研究的独特组合极大地增强了有关发展过程的推理的范围和力量，利用了每种方法的优势并最大程度地限制了它们的局限性。 HD-10333的最终提议延续将从这项具有里程碑意义的儿童发展研究中获得收获，对教育，心理健康和育儿实践产生了重要影响。
