Correlations between visual mismatch negativity (vMMN) and behavioral measurements. a vMMN for the happy (HAP) faces positively correlated with the motor impulsivity (MI) trait (r = 0.546) (upper graph). The actual coefficient is outside the 95 % confidence interval (CI) of the permutation distribution (lower graph). The asterisk indicates statistical significance of p < 0.05. b vMMN for the angry (ANG) faces positively correlated with response time (RT) to targets (upper graph). The coefficient (r = 0.604) is observed outside the 95 % CI (lower graph). c vMMN for the ANG faces positively correlated with emotional distance [ANG minus neutral (NT)] (upper graph). The coefficient (r = 0.458) is also outside the 95 % CI (lower graph)
