Subclaims¶

q2 i? In stepwise regression models, LITG thickness predicted orthography-phonology mapping (t = 3.153, p = 0.005), LSMG thickness predicted phonological awareness (t = 2.438, p = 0.025), and LSTG thickness predicted categorical perception of lexical tones (t = 3.17, p = 0.005), all surviving FDR correction. → Xia Zhichao 2018

q2 · i? · associational · r1

ROI regression analyses (n = 21) in the Results section, with cognitive measures adjusted for age, gender and performance IQ and stepwise selection; all correlations remained significant after FDR correction. No significant result was found for orthographic processing.

"we found a significant contribution of the LITG in predicting orthography-phonology mapping (t = 3.153, p = 0.005), the LSMG in predicting phonological awareness (t = 2.438, p = 0.025), and the LSTG in predicting the categorical perception of lexical tones (t = 3.17, p = 0.005)."

Discussion¶

Related Claims¶

• Word reading efficiency and sentence comprehension show distinct behavioral subcomponent profiles: word reading correlates with phonological subcomponents, comprehension with morphological awareness and orthography-semantic mapping — related
• For sentence comprehension regions, LPHP thickness is correlated with morphological awareness and RV1 thickness with orthography-semantic mapping — related
• The word-reading and comprehension cortical regions are specific to their respective reading level: cross-level correlations were nonsignificant after FDR correction — related
• In Chinese children aged 10-12, oral word reading efficiency is positively correlated with cortical thickness in the LSTG, LITG, LSMG and RSTG — a broader claim this one bears on
