Abstract
Behavioral genetic research on twins has shed light on some of the overlap and unique variance associated with achievement in reading and mathematics. For example, Harlaar et al. (2012) found achievement in math had stronger phenotypic and genetic overlap with reading comprehension than word decoding in a sample of 12 year-old twins. The current study examines the relationship between working memory, math, word decoding, and reading comprehension in a sample of healthy twins. Phenotypic and behavioral genetic models were used to break down the unique and overlapping variance between each construct. The results indicate that working memory and math ability account for significant variance in decoding and comprehension and all of the variables are primarily influenced by additive genetics, as opposed to environment. However, each factor had unique genetic variance that was unaccounted for, suggesting more work needs to be done to understand the etiology of math and reading ability.
