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 logarithmic functional form best fit growth in Numbers Reversed performance in the ECLS-K:2011, indicating rapid early growth that decelerates. → Ahmed 2022

q3 · i? · associational · r2
Prospective longitudinal mixed-effects modeling of the ECLS-K:2011 (N = 18,174, nine waves, ages ~6–11) using W-scores; "A logarithmic functional form best fit growth" with b = 20.714, p < .001.
"A logarithmic functional form best fit growth in numbers reversed performance in the ECLS-K:2011 data (AIC =348702742; BIC =348702778; b = 20.714, p < .001), suggesting that growth begins to grow quickly during early childhood and decelerates over time."
Discussion¶
Related Claims¶
- When PSID-CDS data are restricted to ages 6–11, backward digit span growth is best characterized by a quadratic (not cubic) function — related
- Verbal working memory shows non-linear growth from ages 3–19, with the most rapid growth during childhood and a brief accelerated period during early adolescence — related
- Behavioral self-regulation development between ages three and seven is best described by an exponential (nonlinear) growth curve — related
- Math achievement growth from preschool through second grade is best characterized by a latent basis curve rather than linear, exponential, or quadratic functions — related
- Average and superior children develop at different levels and grow increasingly dissimilar with age, with superior children showing adolescent mental acceleration about one year earlier — related
- Mental growth curves of superior children diverge from those of average children and resemble physical growth curves — related
