q3 i? The HFW-PW contrast elicited larger amplitude responses than the MFW-PW contrast, particularly at the fourth harmonic (4 Hz), replicating the classic word frequency effect in an SSVEP paradigm for the first time. → Fang Wang 2025

q3 · i? · causal · r2

EEG oddball analysis in the same sample (N = 28): significant responses at first and fourth harmonics for HFW-PW (all pFDR < 0.01) but only the first harmonic for MFW-PW (pFDR < 0.001). The authors state this is the first examination of the word frequency effect using an SSVEP paradigm.

"In comparison with the MFW vs. pseudowords contrast, the HFW vs. pseudowords contrast elicited larger amplitude responses, particularly at the fourth harmonic (i.e., 4 Hz), suggesting facilitated access to lexical representations compared to MFW44,45."

Discussion¶

Related Claims¶

• Two weeks of authentic classroom instruction produces lexical-level discriminative cortical responses to newly learned low-frequency words that resemble responses to high-frequency words versus pseudowords — related
• Smaller 1 Hz SSVEP oddball amplitudes to newly learned vocabulary are associated with better word decoding and faster rapid automatic naming, with no such correlations for corpus-based word-pseudoword contrasts — related
