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? Once genetic variance in motivation was accounted for, the residual gene-by-SES interaction on math achievement was not statistically significant, indicating full mediation. → 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
Bivariate Cholesky model with motivation as predictor and math as outcome in the ECLS-B twin sample. The ay′ parameter was not statistically significant, and the authors state the interaction was "fully mediated by genetic differences in learning motivation."
"There is no residual gene-by-SES interaction on Math after accounting for the effects of motivation. Thus, in the current sample, the previously documented gene-by-SES interaction on Math Achievement was fully mediated by genetic differences in learning motivation."
Discussion¶
Learner Variables¶
- Motivation — predictor: learners who differ on it differ in outcomes
- 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
- SES does not moderate genetic, shared, or nonshared environmental variance in four-year-olds' learning motivation — 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
