Correlations between early frontal negativity (EFN) and visual mismatch negativity (vMMN). a Correlation matrix (left part) for the happy (HAP) faces was filtered by an α level of p < 0.05. Gradual red areas represent intervals for significant correlations in permutation correlation analyses. Intervals with relatively strong correlations (3 EFN intervals × 9 vMMN intervals) are framed by a white dotted square and are summarized in a scatter diagram (right upper). Actual coefficient (r = 0.832) is outside the 95 % confidence interval (CI) (gray area) of 10,000 dummy coefficients (right lower). The asterisk indicates statistical significance of p < 0.05. b Correlation matrix (left part) for the angry (ANG) faces was filtered by an α level of p < 0.05. The ANG faces did not yield any significant interval. Intervals corresponding to the HAP faces are framed by a white dotted square and are summarized in a scatter diagram (right upper). Actual coefficient (r = 0.112) is within the 95 % CI (gray area) of the permutation distribution (right lower)
