As the importance of genetic influence in developmental psychopathology becomes widely accepted, we should not lose sight of the importance of genetic research for the investigation and identification of environmental influences. First, genetic research provides the best available evidence for the importance of nongenetic factors in behavioural development. Rarely does genetic influence account for more than half of the variance. Second, genetic research indicates that environmental effects on behavioural development largely involve nonshared environmental processes that make children in the same family different from one another. New research on this topic is presented and implications for research are discussed.
随着遗传影响在发展性精神病理学中的重要性被广泛认可，我们不应忽视遗传研究对于调查和识别环境影响的重要性。首先，遗传研究为非遗传因素在行为发展中的重要性提供了现有最佳证据。遗传影响很少能解释超过一半的方差。其次，遗传研究表明，环境对行为发展的影响很大程度上涉及非共享环境过程，这些过程使得同一家庭中的孩子彼此不同。本文介绍了关于这一主题的新研究，并讨论了其对研究的启示。
