Subclaims¶

q3 i3 Accuracy improved strongly across blocks and both groups reached above 90% accuracy by Block 4, indicating successful learning in both groups. → Cao 2026 q3 i? Group effects and the Block × Condition × Group interaction were non-significant for both accuracy and reaction time learning trajectories. → Cao 2026 (2)

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 · i3 · causal · r2

Mixed repeated-measures ANOVA (Block, Condition, Group) on 31 typical and 31 dyslexic adult readers across four 8-minute training blocks. "Accuracy significantly improved over successive blocks" with η²P = .723; by Block 4 both groups exceeded 90% accuracy on matching pairs.

"Accuracy significantly improved over successive blocks (main effect of Block, F(2.034, 180) = 156.622, p < .001, η²P = .723)."

q3 · i? · causal · r2

The same accuracy ANOVA in adult readers found "The effect of Group and the three-way interaction among Block, Condition, and Group were non-significant"; the article reports the same null for RT. No effect size printed; equivalence was not tested.

"The effect of Group and the three-way interaction among Block, Condition, and Group were non-significant."

Discussion¶

Related Claims¶

• Dyslexic readers score lower on post-training artificial script syllable, letter and word reading but not on basic visual symbol recognition — related
• Symbol-sound learning produces rapid ERP changes in frontotemporal, temporoparietal and occipitoparietal clusters within the first training blocks — related
• Dyslexic readers show the frontotemporal phonological-similarity ERP reduction earlier in learning (block 2) than typical readers (blocks 3–4) — related
• Phonologically similar pairs are learned with lower accuracy and slower reaction-time learning than dissimilar pairs, in both groups — related
• Consonant-confusion error patterns in artificial script reading differ between dyslexic and typical readers — related
• In Block 4, matching vs non-matching pairs differ only in the temporoparietal cluster in S3, with no group differences — related
• HPL students learned as much as Scratch students, with equivalent improvement in both conditions — related
