Subclaims¶

q3 i? For the LFWLearned-LFWUnlearned contrast, 1 Hz amplitudes correlated significantly with word decoding (WJ-LWID, R2 = .27, p < 0.01) and rapid naming of color (RANcolor, R2 =. 3 , pFDR < 0.01); children with smaller amplitudes had better reading performance. → Fang Wang 2025 q3 i? No significant correlations were found between response amplitudes and reading scores for the HFW-PW and MFW-PW contrasts (all R2 < .12, p >0 . 1 ) or for 4 Hz amplitudes in the learned-words contrast (allR2 <. 1 , p > 0.11). → Fang Wang 2025 (2)

q3 · i? · associational · r2

Brain-behavior correlation analysis in the same EEG sample (N = 28), relating 1 Hz oddball amplitudes for the learned-words contrast to grade-scaled reading assessments. The authors report "Children with smaller response amplitudes to new vocabulary learning had better reading performance (faster RAN and better word decoding)".

"For the contrast of LFWLearned-LFWUnlearned, we found significant correla- tions between EEG amplitudes at 1 Hz and both word decoding ability (measured by Woodcock–Johnson letter word identification, WJ-LWID, R2 = .27, p < 0.01) and rapid naming ability for color (RANcolor, R2 =. 3 , pFDR < 0.01, Fig. 3)."

q3 · i? · causal · r2

Null brain-behavior results in the same sample: correlations were non-significant at 4 Hz for the learned-words contrast and for both corpus-based word-pseudoword contrasts. The authors note this replicates their earlier finding of little to no association between responses to frequent words versus pseudowords and reading skill.

"No signi ficant correlations were found for amplitudes at 4H z( a l lR2 <. 1 ,p > 0.11) in this contrast. For the contrasts of HFW-PW and MFW-PW, no signi ficant correlations were found between response amplitudes and reading scores (allR2 < .12, p >0 . 1 ) ."

Learner Variables¶

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