Abstract/Description: 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 ability. Data are available on 314 pairs of monozygotic and same-sex dizygotic twins analyzed across five waves of assessment. Univariate analyses provide a range of estimates of genetic (h²=.00-.63) and shared environmental influences (c²=.15-.52) across math calculation, fluency and problem solving measures. Multivariate analyses indicate genetic overlap between math problem solving with general cognitive ability and reading, whereas math fluency shares significant genetic overlap with reading fluency and general cognitive ability. Further, math fluency has unique genetic influences. In general, math ability has shared environmental overlap with general cognitive ability and decoding. These results indicate that aspects of math that include problem solving have different genetic and environmental influences than math calculation. Moreover, math fluency, a timed measure of calculation, is the only measured math ability with unique genetic influences.
