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? Nonverbal IQ (R² = .18) and cumulative risk (R² = .03) each uniquely predicted reading readiness, jointly explaining 31% of its variance; IQ did not predict attention and behaviour. → Dilnot 2017

q3 · i? · associational · r2
Parallel regression analyses entering the cumulative risk index with nonverbal IQ (performance IQ at T1) as predictors of school-entry outcomes. The article reports the two factors "predicted 31% of the variance in reading readiness and 10% of variance in attention and behaviour".
"Together these two factors assessed in preschool predicted 31% of the variance in reading readiness and 10% of variance in attention and behaviour at school entry."
Discussion¶
Learner Variables¶
- General Cognitive Ability — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Among child health risks, only hearing problems uniquely predicted reading readiness, accounting for 5.5% of variance — a narrower finding that bears on this claim
- Home literacy environment and family stresses predict attention and behaviour at school entry — related
- Family-risk of dyslexia does not predict readiness to learn once other distal, proximal and child risk factors are controlled — related
- Children's challenging behaviour, not ability (IQ), is the major source of demand on teachers, and one child's disruptive behaviour can reduce classmates' access to the educator — related
- Home literacy environment and child health predict reading readiness at school entry, and socioeconomic status stops being a significant predictor once home literacy environment is entered (suggestive of mediation, not tested) — related
- Family-risk of dyslexia and preschool language impairment are additive risk factors for reading readiness and attention and behaviour — related
