a in the left panel, VNAS displayed higher responses to negative affect, while it also significantly responded to positive compared to neutral conditions; in the middle and right panels, after two correction methods (actual arousal ratings, BAAS response correction), VNAS showed similar responses to positive and neutral conditions (study 1, n = 63). For details, see Supplementary Results. b in the left panel, VIDS showed higher responses to targeted emotion (i.e., disgust), while it significantly responded to happiness and fear compared to neutral emotions; in the middle and right panels, after arousal-rating-corrected or BAAS-responses corrected, VIDS still performed higher response to disgust, while it showed comparable responses to happiness, fear, and neutral emotions (study 1, n = 63). Of, note, the violin and box plots show the distributions of the signature response. The boxplot’s boundaries are defined by the first and third quartiles, while the whiskers extend to the maximum and minimum values within the range of the median ± 1.5 times the interquartile range. *P < 0.05, **P < 0.01, ***P < 0.001, NS P > 0.05. P values in forced-choice tests were based on two-sided binomial tests. VNAS visually negative affect signatures, VIDS visually induced disgust signature. Source data are provided as a Source Data file.
