The interaction between CGI‐A and valence approached significance (Est.0.02, p = 0.051), such that higher CGI‐A scores was associated with a greater difference between corrugator activity during negative versus neutral (negative > neutral) conditions.
For SCARED scores there was a positive slope between corrugator magnitude and SCARED scores, but these relations did not reach statistical significance (all Est. < 0.01, all p > 0.15; Tables 6 and 7 ). 3.4 Average corrugator magnitude during picture exposure periods During picture viewing there was a main effect of valence, such that corrugator magnitude increased more during negative versus neutral pictures (Est. = 0.06, p < 0.001) (Figure 2a , Table 8 ).
