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 i2 Adults with RD showed greater hemodynamic response than adults without RD during perception of Spanish syllables with high similarity to Chinese in right IFG and right DLPFC, with no child-group difference, indicating a smaller activation decrease from childhood to adulthood in RD. → Yang Fu 2024

q3 · i2 · associational · r2
fNIRS GLM ANCOVA (group × age × similarity × syllable consistency, Raven covariate) in 87 Chinese participants during Spanish syllable perception. The quote reports the three-way interaction with printed effect sizes "ηp 2 = 0.11" in right IFG and "ηp 2 = 0.17" in right DLPFC; simple effects showed adults with RD more activated than control adults for high-similarity syllables.
"A signi ficant three-way (age × group × similarity) interaction was found in CH31 (right IFG, F(1,80) = 10.07, pFDR = 0.048, ηp 2 = 0.11) and CH37 (right DLPFC, F(1,80) = 16.16, pFDR = 0.006, ηp 2 = 0.17)."
Discussion¶
Related Claims¶
- Children with RD produce Spanish vowels less similar to a native speaker than control children, but adults with and without RD do not differ — related
- Right DLPFC activation during Spanish perception correlates negatively with pseudoword rhyming in children with RD but not adults with RD — related
- RD readers show reduced deactivation of left MTG (channel 22) during Spanish compared to Chinese speech production — related
