Subclaims¶

q3 i2 SM pairs elicited significantly less negative ERP responses than DM pairs in S2 over temporoparietal (η²P = .12) and occipitoparietal (η²P = .11) clusters and in S3 over frontotemporal clusters (η²P = .18). → Cao 2026

ERP Condition effects across 62 adults during training: "SM pairs elicited significantly less negative ERP responses compared to DM pairs" in S2 temporoparietal (η²P = .12) and occipitoparietal (η²P = .11) clusters and S3 frontotemporal cluster (η²P = .18).

"SM pairs elicited significantly less negative ERP responses compared to DM pairs in the S2 window in the temporoparietal cluster (Condition: F(1, 60) = 8.50, p = .005, η²P = .12; Δ= .25, SE = .09) and the occipitoparietal cluster (Condition: F(1, 60) = 7.83, p = .007, η²P = .11; Δ = .24, SE = .09) and in the S3 window in the frontotemporal cluster (Condition: F(1, 60) = 13.27, p = .001, η²P = .18; Δ = .30, SE = .08)."

Discussion¶

Related Claims¶

• Dyslexic readers show the frontotemporal phonological-similarity ERP reduction earlier in learning (block 2) than typical readers (blocks 3–4) — related
• Symbol-sound learning produces rapid ERP changes in frontotemporal, temporoparietal and occipitoparietal clusters within the first training blocks — related
• Phonologically similar pairs are learned with lower accuracy and slower reaction-time learning than dissimilar pairs, in both groups — related
• In Block 4, matching vs non-matching pairs differ only in the temporoparietal cluster in S3, with no group differences — related
