Subclaims¶

q3 i3 Learning-related ERP changes occurred in time windows S2 (150–210 ms) and S3 (213–333 ms) over frontotemporal and occipitoparietal clusters and in S3 over temporoparietal clusters. → Cao 2026 q3 i? No learning-related ERP effects appeared in the earliest S1 (74–134 ms) window. → Cao 2026 (2)

q3 · i3 · causal · r2

EEG recorded from 62 adults during four training blocks showed "Learning-related changes occurred in time windows S2 and S3 in the FT and OP clusters and in S3 in the TP cluster", with reported Block effects up to η²P = .33 (FT S3 decrease).

"Learning-related changes occurred in time windows S2 and S3 in the FT and OP clusters and in S3 in the TP cluster."

The authors report "Learning-related ERP modulations did not reach significance in the earliest time window (S1: 74-134 ms)", suggesting initial sensory-perceptual processing remained unchanged; no effect size printed.

"Learning-related ERP modulations did not reach significance in the earliest time window (S1: 74-134 ms)."

Discussion¶

Related Claims¶

• Dyslexic readers show the frontotemporal phonological-similarity ERP reduction earlier in learning (block 2) than typical readers (blocks 3–4) — a narrower finding that bears on this claim
• Phonologically similar pairs elicit reduced ERP responses in temporoparietal and occipitoparietal (S2) and frontotemporal (S3) regions — related
• In Block 4, matching vs non-matching pairs differ only in the temporoparietal cluster in S3, with no group differences — related
• Adult typical and dyslexic readers show successful and comparable behavioral learning of novel symbol-speech sound associations — related
