ABSTRACT
Age-group membership effects on explicit emotional facial expressions recognition have been widely demonstrated. In this study we investigated whether Age-group membership could also affect implicit physiological responses, as facial mimicry and autonomic regulation, to observation of emotional facial expressions. To this aim, facial Electromyography (EMG) and Respiratory Sinus Arrhythmia (RSA) were recorded from teenager and adult participants during the observation of facial expressions performed by teenager and adult models. Results highlighted that teenagers exhibited greater facial EMG responses to peers' facial expressions, whereas adults showed higher RSA-responses to adult facial expressions. The different physiological modalities through which young and adults respond to peers' emotional expressions are likely to reflect two different ways to engage in social interactions with coetaneous. Findings confirmed that age is an important and powerful social feature that modulates interpersonal interactions by influencing low-level physiological responses.

Panel (b) - RSA-response of Adult-Group and Teenager-Group, to Adult-stimuli and Teenager-stimuli. Error bars represent SE. * = p<0.05, ** = p<0.005.

Mentions: Repeated measures ANOVA conducted on Corrugator EMG activity revealed the significant main effects of Stimuli-Age (F1,34 = 4.47 p = 0.041; n2p = 0.12) and Emotion (F4,136 = 3.82 p = 0.005; n2p = 0.10) factors. Furthermore, the interactions Stimuli-Age by Group (F1,34 = 6.56 p = 0.015; n2p = 0.16), Stimuli-Age by Epoch (F9,306 = 2.11 p = 0.028; n2p = 0.06) and Emotion by Epoch (F36,1224 = 2.30 p = 0.000; n2p = 0.06) were significant. Post hoc comparisons conducted on the main effect of Stimuli-Age showed that, regardless of group membership, all participants showed higher EMG response to Teenager-stimuli (0.38 µV; SE 0.15; 95% CI 0.08 to 0.69) than to Adult-stimuli (0.24 µV; SE 0.18; 95% CI −0.14 to 0.61) (p = 0.042). Post hoc analysis performed on the main effect of Emotion revealed that Anger (0.66 µV; SE 0.27; 95% CI 0.11 to 1.20) was significantly higher than Joy (−0.45 µV; SE 0.19; 95% CI −0.84 to −0.07) (p = 0.048), whereas Sadness (1.06 µV; SE 0.60; 95% CI −0.18 to 2.30) was significantly higher than Joy (p = 0.004) and Neutral stimuli (−0.07 µV; SE 0.12; 95% CI −0.32 to 0.17) (p = 0.042). Noteworthy, post hoc comparisons conducted on the interaction Stimuli-Age by Group revealed that TG had higher Corrugator EMG activity during the viewing of Teenager-stimuli (0.34 µV; SE 0.21; 95% CI −0.09 to 0.78) than during the observation of Adult-stimuli (0.02 µV; SE 0.26; 95% CI −0.51 to 0.56) (p = 0.002) (see Figure 2, panel A).
