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.
q2 i? Residual correlations between listening comprehension and passage reading, spelling, and phonemic awareness were near zero (0.08, 0.02, 0.11) despite moderate genetic correlations (0.64, 0.66, 0.66). → Chin Yang Shapland 2021

q2 · i? · associational · r2
IPC-model correlation comparison in the passage reading subset GSEM (N = 6453): the printed residual correlations for listening comprehension versus passage reading, spelling and phonemic awareness were "0.08 (SE = 0.05), 0.02 (SE = 0.05) and 0.11 (SE = 0.07)" against genetic correlations of 0.64–0.66.
"respective residual correlations were 0.08 (SE = 0.05), 0.02 (SE = 0.05) and 0.11 (SE = 0.07), while corresponding genetic correlations were 0.64 (SE = 0.11), 0.66 (SE = 0.11), and 0.66 (SE = 0.11)"
Discussion¶
Related Claims¶
- Literacy, phonological awareness, oral language and PWM abilities share a large proportion of underlying genetic variation in unrelated youth — related
- Reading fluency, spelling, phonemic awareness, listening comprehension and non-word repetition are moderately heritable (SNP-h2 30–50%) in unrelated youth — related
