The Colorado Learning Disabilities Research Center and Brian Byrne's research group at the University of New England in Australia will collaborate to assess genetic and environmental influences on the early development of reading and attention, and will attempt to identify the specific psychological processes that mediate these influences. We propose to recruit and test 340 twin pairs in Australia at preschool age to minimize contamination of our measures with reading experience, and to retest the twins at the end of kindergarten, first and second grade, to monitor growth during this critical period of early reading development. Project V will use the same measures with the Australian twins as those used in a companion project to be conducted with twins in Colorado under a new 5-year R01 grant from NICHD (608 pairs), and a smaller project currently underway in Australia, funded by the Australian Research Council (110 pairs). The Australian twins, combined with the Colorado twins (1,058 pairs total), will substantially increase statistical power for exploring the genetic and environmental etiology of both high and low performance in this large epidemiological sample. The proposed epidemiological sample and developmental/longitudinal design beginning in preschool will complement cross-sectional research with older school- history RD- and/or ADHD-selected twins studied in projects I-IV.

科罗拉多州学习障碍研究中心和澳大利亚新英格兰大学布莱恩·伯恩的研究小组将合作评估基因和环境对阅读和注意力早期发展的影响，并试图确定调节这些影响的特定心理过程。我们建议在澳大利亚招募和测试340对学龄前双胞胎，以最大限度地减少我们的措施对阅读经验的影响，并在幼儿园结束时、一年级和二年级重新测试这对双胞胎，以监测在这一早期阅读发展的关键时期的成长。项目V将对澳大利亚双胞胎使用的措施与在科罗拉多州由NICHD提供的新的5年期R01赠款(608对)下与双胞胎一起进行的伙伴项目中使用的措施相同，以及澳大利亚目前正在进行的一个由澳大利亚研究理事会资助的较小项目(110对)中使用的措施。澳大利亚双胞胎和科罗拉多双胞胎(总计1,058对)相结合，将大大增加统计能力，在这个大的流行病学样本中探索高和低表现的遗传和环境病因。拟议的流行病学样本和从学龄前开始的发育/纵向设计将补充项目I-IV中研究的具有较大学校病史的RD和/或ADHD双胞胎的横断面研究。
