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 i0 Visual acuity shows an attenuated but significant positive partial correlation with GCSE scores after extensive demographic and cognitive adjustment (r = 0.05). → Schmitz 2023

q3 · i0 · associational · r3
Cohort correlation analysis in the ALSPAC sample. The article reports an "attenuated, but significant association" between visual acuity and GCSE scores (r = 0.05, p = 0.001), remaining after adjusting for sex, age, reading skill, IQ measures, and SES.
"Partial correlation analysis between visual acuity and GCSE adjusting for sex, age, reading skill, verbal IQ, performance IQ, and SES revealed an attenuated, but significant association ( r(5662) = 0.05, 95% CI = [0.02, 0.08], p = 0.001)."
Discussion¶
Related Claims¶
- Visual acuity is not correlated with hearing threshold in childhood, suggesting independence of the two sensory phenotypes — related
- IQ and working memory are reliable predictors of academic achievement at the beginning of school when domain knowledge is not controlled — related
- Previous domain knowledge accounts for most of the variance in later achievement, considerably reducing the predictive impact of IQ and WM — related
