The Behavior Genetic Studies on Developmental Dyslexia

发展性阅读困难是学龄儿童常见的学习障碍,其病源学问题极其复杂,很多行为遗传学家针对遗传和环境对阅读困难的影响进行了大量的研究。该文对阅读困难的行为遗传学研究进行了回顾,特别是综合介绍了分子遗传学研究所取得的重要成果及不足。最后指出了研究所面临的困难和将来的方向,并对与教育的关系进行了总结与评价。

Developmental dyslexia is very common in school children and its etiology is very complicated. Many researches have been carried out to study the genetic and environmental influence on dyslexia. This paper reviews the behavior genetic researches on dyslexia, especially the important results and weaknesses of molecular genetic studies. The difficulties faced and the direction in the future are suggested and the relationship between behavior genetic studies and education is summarized and evaluated.
