q3 i3 Activation of CH37 during perception of high-similarity Spanish syllables was negatively correlated with pseudoword rhyming judgment in children with RD, and this correlation differed significantly from that in adults with RD. → 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 · i3 · associational · r2

Pearson correlations between channel activation and phonological awareness within RD groups. The quote reports the printed correlation "r = −0.629, pFDR = 0.084" for children with RD, marginal after FDR correction; Steiger's Z test showed the child and adult correlations differed (z = 2.90, p = 0.004).

"A negative correlation was found between the activation of CH37 during perception of Spanish syllables with high similarity to Chinese and pseudoword rhyming judgment (r = −0.629, pFDR = 0.084) for children with RD"

Discussion¶

Learner Variables¶

• Auditory Processing — predictor: learners who differ on it differ in outcomes

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
• RD shows a slowed developmental reduction of right IFG and right DLPFC activation during perception of Spanish syllables highly similar to Chinese — related
