Significant effects from ANOVA-type analyses are marked in bold. Multiple comparisons assessing main trends for emotion were conducted using robust rank-based Tukey-type nonparametric contrasts (ps < .05)

F* = the ANOVA-type statistic, P = posed clips, S = spontaneous clips, Ang = anger, Fea = fear, Hap = happiness, Sad = sadness. Abbreviations of acoustic cues are explained in Table 2

^adf1 = 1 for the main effect of stimulus type

^bReported df-values are Box-corrected, see Brunner et al. (1997)
