Virtuous character development in children is correlated with parenting behavior, but the role of genetic influences in this association has not been examined. Using a longitudinal twin/sibling study (N = 720; Time 1 (T1) Mage = 12-14 years, Time 3 (T3) Mage = 25-27 years), the current report examines associations among parental negativity/positivity and offspring responsibility during adolescence, and subsequent young adult conscientiousness. Findings indicate that associations among parental negativity and offspring virtuous character during adolescence and young adulthood are due primarily to heritable influences. In contrast, the association between concurrent parental positivity and adolescent responsibility was due primarily to heritable and shared environmental influences. These findings underscore the contributions of heritable influences to the associations between parenting and virtuous character that have previously been assumed to be only environmentally influenced, emphasizing the complexity of mechanisms involved in the development of virtuous character.

我继承了我的道德指南针吗？检查道德品格发展的社会化和唤起机制。


儿童的道德品格发展与养育行为相关，但遗传影响在这种关联中的作用尚未得到研究。本报告采用纵向双胞胎/兄弟姐妹研究（N = 720；时间 1 (T1) Mage = 12-14 岁，时间 3 (T3) Mage = 25-27 岁），研究了父母消极/积极与后代责任之间的关联青春期以及随后的年轻人的责任心。研究结果表明，青春期和成年早期父母的消极情绪与后代的美德性格之间的关联主要是由于遗传的影响。相比之下，同时父母的积极性和青少年责任感之间的关联主要是由于遗传和共同的环境影响。这些发现强调了遗传影响对养育子女与美德品格之间关联的贡献，而此前人们认为这种影响仅受环境影响，强调了美德品格发展所涉及机制的复杂性。
