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? Vocabulary showed significant linear increases (b = 4.61, p < .001) with acceleration (b = 1.71, p < .01); social communication showed linear increases (b = .36, p < .001) with deceleration (b = −.22, p < .001). → Ramsook K. Ashana 2020

Growth multilevel models across three waves (N = 164) with time centered at Wave 1. The article reports "significant linear increases in social communication skills across waves (b = .36, SE = .06, p < .001) and deceleration of growth"; vocabulary showed linear increase and acceleration.
"The best-fitting model for social communication skills included linear and quadratic terms and revealed overall significant linear increases in social communication skills across waves (b = .36, SE = .06, p < .001) and deceleration of growth (b = −.22, SE = .03, p < .001)."
Discussion¶
Related Claims¶
- Initial levels of vocabulary and social communication skills each predict kindergarten reading achievement, but only rate of growth in social communication skills incrementally predicts reading — related
- Growth in both vocabulary and social communication skills predicts kindergarten math achievement — related
- AI ethics research shows a pronounced acceleration in publications after 2021, with nonlinear accelerating growth rather than linear development — related
