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.
q1 i? The authors propose that because skill acquisition thickens specific cortical regions while consolidation is associated with cortical thinning, positive CT-reading correlations should appear at young ages and negative ones at later stages. → Xia Zhichao 2018

An authors' interpretation in the Discussion, described by them as based on "weak and indirect" evidence from prior skill-learning and reading studies (e.g., cortical thickening during learning, thinning during consolidation). No new data test this hypothesis in the present study.
"As for reading development, we hypothesize that at young ages, the correlations are positive, whereas at later stages the correlations are negative. Although weak and indirect, evidence to date seems to be in line with this hypothesis."
