Subclaims¶

q3 i2 A significant Block × Condition × Group three-way interaction in frontotemporal clusters reflects an earlier-emerging SM-vs-DM ERP reduction in dyslexic readers (block 2) than typical readers (blocks 3–4). → Cao 2026

Evidence¶

Cao 2026¶

Cao, Y., Zhang, M., Gentile, F. & Bonte, M. (2026). Dynamic behavioral and neural correlates of letter-speech sound learning in typical and dyslexic readers. npj Science of Learning. https://doi.org/10.1038/s41539-026-00410-0

q3 · i2 · causal · r2

Second ANOVA with group factor in the EEG training data: "a significant Block × Condition × Group three-way interaction in frontotemporal clusters" (η²P = .05, a medium effect by the η² code table); pairwise comparisons located the SM–DM reduction at block 2 in DD and blocks 3–4 in TR.

"revealed a significant Block × Condition × Group three-way interaction in frontotemporal clusters (F(3,180) = 1.89, p = .021, η²P = .05), with no significant group main effect or two-way interaction effects"

Discussion¶

Related Claims¶

• Consonant-confusion error patterns in artificial script reading differ between dyslexic and typical readers — related
• Dyslexic readers score lower on post-training artificial script syllable, letter and word reading but not on basic visual symbol recognition — related
• Phonologically similar pairs elicit reduced ERP responses in temporoparietal and occipitoparietal (S2) and frontotemporal (S3) regions — related
• Symbol-sound learning produces rapid ERP changes in frontotemporal, temporoparietal and occipitoparietal clusters within the first training blocks — a broader claim this one bears on
• Phonologically similar pairs are learned with lower accuracy and slower reaction-time learning than dissimilar pairs, in both groups — related
• Adult typical and dyslexic readers show successful and comparable behavioral learning of novel symbol-speech sound associations — related
• In Block 4, matching vs non-matching pairs differ only in the temporoparietal cluster in S3, with no group differences — related
