Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? A univariate twin model of motivation found no statistically significant SES moderation of genetic, shared environmental, or nonshared environmental variance in motivation. → Tucker-Drob 2011
Evidence¶
Tucker-Drob 2011¶
Tucker-Drob, Elliot M., & Harden, K. Paige. (2011). Learning Motivation Mediates Gene-by-Socioeconomic Status Interaction on Mathematics Achievement in Early Childhood. Learning and Individual Differences. https://doi.org/10.1016/j.lindif.2011.11.015
q3 · i? · associational · r2
Univariate behavioral genetic model of parent-rated learning motivation in the ECLS-B twin sample. In the final reduced model, genes accounted for 49% and the nonshared environment 51% of remaining motivation variance; equivalence was not tested, only nonsignificance reported.
"The full Step 1 model indicated no statistically significant evidence for SES moderation of the magnitude of genetic, shared environmental, or non-shared environmental variance in motivation."
Discussion¶
Learner Variables¶
- Socioeconomic Status — moderator: an instructional effect differs by group
Related Claims¶
- Genes account for negligible variance in four-year-olds' math scores at very low SES but over 40% at very high SES — related
- Genetic differences in learning motivation are more strongly predictive of math achievement among four-year-olds in higher-SES homes — related
- Genetic variance in learning motivation fully mediates the gene-by-SES interaction on four-year-olds' math achievement — related
- SES accounts for a modest 9% of variance in learning motivation but a larger 28% of variance in math achievement among four-year-olds — related
- The reverse math-to-motivation genetic pathway is not moderated by SES, supporting a directional motivation-to-achievement relation — related
