highly significantp < 0.001
Analysis of difference waves at the FCz electrode showed highly significant group differences for Novel-Standard comparisons (t(50) = 4.84, p < 0.001), with NH children exhibiting substantially larger amplitudes (M = 14.75 μV, SD = 5.56) compared to CI users (M = 7.34 μV, SD = 5.47), representing a large effect size (d = 1.34).
