Simple regularity (ITD change): mean amplitudes of the P0, Na, Pa and Nb components of the MLR and the MMN range.

<p>Mean amplitudes (in µV) and standard errors (in parentheses) elicited by standard (std) and deviant (dev) tones for the Na component of the MLR and the MMN range at the Fz electrode. Note that standard tones for the simple regularity correspond to the standard tones in the reverse block, which had the same physical characteristics as the deviants in the tone-alternation sequence. Asterisks indicate significant differences between standard and deviant responses [*<i>p</i><0.05; **<i>p</i><0.001].
