Relationship between vMMNs and perceptual alternation across participants. The correlations between the differential proportion of perceptual alternation (DEV–STD) and the latency or amplitude of vMMN are shown for a vMMN1 and b vMMN2. The amplitudes of vMMN1 and vMMN2 appeared to decrease with an increase in the differential proportion (i.e., the amplitudes of both vMMN1 and vMMN2 were augmented as the proportion of perceptual alteration increased). A negative correlation was observed between the differential proportion and amplitude of vMMN for vMMN1, but not for vMMN2. Data defined as outliers were excluded from these analyses (see the “Results” section)
