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 A significant Language by Group interaction in left MTG: control participants deactivated more for Spanish than Chinese production, whereas RD participants deactivated more for Chinese than Spanish. → Yang Fu 2024
Evidence¶
Yang Fu 2024¶
Yang Fu, Xiaohui Yan, Jiaqi Mao, Haibin Su & Fan Cao. (2024). Abnormal brain activation during speech perception and production in children and adults with reading difficulty. npj Science of Learning. https://doi.org/10.1038/s41539-024-00266-2
q3 · i2 · associational · r2
fNIRS GLM ANCOVA (group × age × language, Raven covariate) during imitation of Chinese pseudowords and Spanish words. The quote reports the Language × Group interaction with the printed effect size "ηp 2 = 0.14"; simple effects showed controls deactivated more for Spanish while RD showed the reversed pattern.
"a signi ficant Language by Group interaction was observed in channel 22 (left MTG,F(1,74) = 11.53,pFDR = 0.048,ηp 2 =0 . 1 4 )"
Discussion¶
Related Claims¶
- SVM classification of fNIRS activation patterns distinguishes RD with 60–90% accuracy, with left MTG channels the most consistent discriminative features — related
- RD shows a slowed developmental reduction of right IFG and right DLPFC activation during perception of Spanish syllables highly similar to Chinese — related
