Modulation of facial muscle responses by another person’s presence and affiliative touch during affective image viewing

Figures & data

Figure 1 Facial muscle responses to affective stimuli per experimental condition. Note. The EMG signal representing facial muscle responses was z-standardised and baseline-corrected. The figures present (a) zygomaticus facial muscle responses and (b) corrugator facial muscle responses to positive, negative, and neutral affective stimuli for each of the five experimental conditions. Error bars display the SE of the M.
