Table 1.

Mean amplitudes of the ERP components calculated from the difference waveforms (i.e., delayed minus no-delay) for the 12th B bursts.

	Attentive condition (P3b)		Attentive condition (MMN/N2b)		Passive condition (MMN)
	SSEP	no-SSEP	SSEP	no-SSEP	SSEP	no-SSEP
Average amplitude of difference waveforms (μV)	1.70 (0.90)	1.25 (1.45)	−0.44 (1.30)	−0.16 (1.25)	−0.85 (1.60)	0.45 (1.41)
t-value (one-tailed one-sample t-test for the difference waveforms)	t(1, 8) = 5.34	t(1, 8) = 2.93	t(1, 8) = −1.01	t(1, 8) = −0.39	t(1, 8) = −1.59	t(1, 8) = 0.89
p-value (statistical significance level α < 0.0083)	0.0003	0.0022	0.1707	0.3534	0.0749	0.2005

Standard deviations are shown in the parentheses. The t- and p-values were calculated from one-tailed one-sample t-tests comparing the amplitudes of the ERP component with the zero baseline.
