Figure 2

Note. (A) Face actions for Experiment 1C and 2 include eyebrow widening (labeled D2), nose lengthen (labeled D5 + D6), lip raise (labeled D7), mouth widen (labeled D8) and mouth open (labeled D9). (B) Plots from Experiment 1C are for each target emotion for mouth widening and mouth opening (purple = spontaneous, green = posed), and eyebrow widening collapsed across production condition. The asterisk denotes significance at p < .05, following Bonferroni alpha correction applied to each comparison. For each condition, data points indicate individual participants. The thick black horizontal line represents the sample mean, the surrounding box represents 1 SEM and the shaded region represents 1 SD.
