q3 i2 The speech stimulus was reconstructed more accurately from EEG in high- vs low-interest segments (d=0.56), and TRF peaks were significantly modulated by interest level. → Levy 2025

TRFs estimated separately for high- vs low-interest segments (n=32) showed early (~160ms) and late (~350ms) peaks larger for high interest and the ~200ms peak larger for low interest (all p's < 0.02, cluster-corrected), with printed decoding "Cohen’s d=0.56".

"the speech stimulus could be reconstructed more accurately in the high vs. low interest condition [t(31)=3.17, p=0.003, Cohen’s d=0.56"
