| Abstract | Investigated the genetic and environmental influences on low early mathematics performance in twin pairs in the context of normal variation. Data came from the Twins Early Development Study (TEDS) of twins born in Britain during 1994 and 1995. A total of 2,178 pairs of twins from the lowest 15 percent of a representative United Kingdom sample were included in the study: 1,027 male pairs (mean age 7.1 years) and 1,151 female pairs (mean age 7.1 years). Children were grouped according to their mathematical ability: low using and applying mathematics group (387 twins, i.e., 187 monozygotic (MZ) and 203 dizygotic (DZ) same-sex twin pairs); low numbers group (378 twins, i.e., 178 MZ and 200 DZ same-sex twin pairs); and the low shapes, space, and measures group (349 twins, i.e., 171 MZ and 198 DZ same-sex twin pairs). Moreover, standardized teacher assessments were included in the analyses. Model-fitting analyses of mathematics performance and low performance yielded similar results: The heritability estimate for the teacher-reported mathematics performance composite is 0.66, and the group heritability estimate for low performance is 0.65. The results are consistent with the hypothesis that the same genetic and environmental factors are largely responsible for low mathematics performance as for normal variations in mathematics. In conclusion, limitations of the study and directions for further research are discussed. (ZPID). |
