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? Accuracy and RT on the ANS acuity task at Time 1 were significant unique predictors of TEMA-3 math scores at Time 2 (partial r2 = 0.07 and 0.06). → Libertus Melissa E. 2013

q3 · i? · associational · r2
Longitudinal regression (model 1, Table 4) predicting TEMA-3 at Time 2 from Time 1 measures in 204 preschoolers tested twice about six months apart; the model predicted significant variance (R2 = 0.61, F(4,129) = 50.03, p < 0.001), with "accuracy and RT on the ANS acuity task were significant unique predictors of later math ability" (partial r2 = 0.07 and 0.06).
"Most importantly, in model 1 accuracy and RT on the ANS acuity task were significant unique predictors of later math ability, even when controlling for initial math ability, age, and expressive vocabulary at Time 1"
Discussion¶
Related Claims¶
- Early ANS acuity does not predict later expressive vocabulary; only initial vocabulary size predicts vocabulary six months later — related
- ANS acuity is a unique concurrent predictor of preschool math ability beyond expressive vocabulary, non-numerical attention RT, and memory span — related
- Initial math ability is the largest single predictor of later math ability, accounting for 45% of variance in later TEMA-3 scores — related
- Early numeracy mastery at 54 months predicts college attendance — related
- ANS acuity correlates with later number sets fluency but does not emerge as a unique predictor once symbolic knowledge is controlled — related
- Children's knower level of verbal number words is cross-sectionally associated with ANS acuity even after controlling for age and sex — related
- Preschoolers' ANS task performance follows Weber's Law: accuracy decreases as numerical ratio approaches equality, and improves with age over six months — related
- Early numeracy mastery at 54 months predicts high school math course-taking — related
