Subclaims¶

q2 i? In a supplementary analysis of individual measures, genetic and environmental correlations with word decoding and reading comprehension did not vary significantly as a function of the specific mathematics test. → Harlaar 2012

Evidence¶

Harlaar 2012¶

Harlaar, N., Kovas, Y., Dale, P. S., Petrill, S. A., & Plomin, R. (2012). Mathematics is differentially related to reading comprehension and word decoding: Evidence from a genetically-sensitive design. Journal of Educational Psychology, 104(3). https://doi.org/10.1037/a0027646

q2 · i? · associational · r3

Supplementary Cholesky decomposition applied to the individual mathematics, word decoding, and reading comprehension measures rather than latent factors. Genetic correlations "did not vary significantly as a function of the specific mathematics test"; the same pattern held for shared and nonshared environmental influences.

"The genetic correlations between mathematics and word decoding did not vary significantly as a function of the specific mathematics test."

Discussion¶

Related Claims¶

• The genetic correlation between mathematics and reading comprehension (.76) is significantly higher than between mathematics and word decoding (.50) — related
• At age 12, mathematics is more strongly correlated with reading comprehension than with word decoding at the phenotypic latent-factor level — related
• Reading comprehension retains genetic and nonshared environmental influences independent of both mathematics and word decoding — related
• Shared environmental influences on mathematics, word decoding, and reading comprehension are nearly identical across the three domains — related
