Multilinear regression between behavioral (y axis) and electrophysiological (x axis) measures. Estimation of the z-scores of speech comprehension, respectively, of the z-scores of the comfort rating from the z-scores of the peak amplitude of the envelope-MGF (A and D), the amplitude of the second peak of the pulse-MGF (B and E), and the gain in the accuracy of the EEG reconstruction from the speech envelope (C and F). The only significant neural predictor of behavior is the peak amplitude of the envelope-MGF: Higher amplitudes signify a higher comfort rating (D).
