The goal of this first major report from the Western Reserve Reading Project Math component is to explore the etiology of the relationship among tester-administered measures of mathematics ability, reading ability and general cognitive...
Underperformance in math is a problem with increasing prevalence, complex etiology, and severe repercussions. This study examined the etiological heterogeneity of math performance in a sample of 264 pairs of 12-year-old twins assessed on...
Exploring how symptoms of Attention‐Deficit/Hyperactivity Disorder are related to reading and mathematics performance: General genes, general environments
