Putting a label on someone: impact of schizophrenia stigma on emotional mimicry, liking, and interpersonal closeness.

Affiliation is both an antecedent and a consequence of emotional mimicry (i.e. imitating a counterpart's emotional expression). Thus, interacting with a disliked partner can decrease emotional mimicry, which in turn can further decrease liking. This perpetuating circle has not been investigated in the context of mental health stigma yet. The present study tested the influence of the label "schizophrenia" on liking, interpersonal closeness, and emotional mimicry. In an online experiment (n = 201), participants recruited from the general population saw several videos of actors displaying emotional expressions. Actors were described with one of four labels: "schizophrenia", "healthy", "diabetes", and a negative adjective (e.g. "hot-tempered"). Emotional mimicry was measured using OpenFace 2.2. Liking and interpersonal closeness were assessed with questionnaires. Overall, compared to other labels, participants reported less liking and interpersonal closeness to the actor with the schizophrenia label. However, no effect on emotional mimicry was found. The decreased liking of the schizophrenia actors was explained by a lack of knowledge about schizophrenia and the explicit stigma of schizophrenia. Our study contributes to the literature by highlighting the need to reduce the stigma of schizophrenia.

Wrinkles are neither beautiful nor nice: The effect of facial wrinkles on person perception and interpersonal closeness.

With age, we develop facial wrinkles, which change the appearance of the face making it less attractive. Winkles and folds also "mimic" facial expressions, such that older neutral faces appear more emotional. Both processes can influence first impressions negatively. We obtained ratings of attractiveness, closeness, and emotional expressivity as well as first impressions from 353 participants, recruited from Prolific, for avatars with and without facial wrinkles. Older appearing, wrinkled faces were judged as less attractive and less favorably on traits related to pleasantness and trustworthiness, they were perceived as showing more negative emotions and participants rated themselves as less close. The effects on first impressions and perceived closeness were mediated by attractiveness and perceived negative emotions. These findings suggest that in initial encounters older people may often be perceived as less pleasant for no other reason than the wrinkles in their face and the judgments of attractiveness and emotionality associated with them.

Narcissism predicts noise perception but not signal decoding in emotion.

Grandiose narcissists claim that they have better-than-average emotion recognition abilities, but many objective tests do not support this claim. We sought to clarify the relation between grandiose (both agentic and communal) narcissism and emotion recognition by taking a closer look at the components of emotion recognition. In two studies (N1 = 147, N2 = 520), using culturally distinct samples and different stimulus materials, we investigated the relation between grandiose narcissism and signal decoding (accurate view of the intended emotion displayed in an expression) as well as noise perception (inaccurate deciphering of secondary emotions that are not part of the emotional message). Narcissism was inconsistently related to signal decoding, but consistently and positively related to noise perception. High grandiose (agentic and communal) narcissists are not necessarily better at signal decoding, but are more susceptible to noise perception. We discuss implications for narcissists' social interactions and interpersonal relationships.

Influence of child and adult faces with face masks on emotion perception and facial mimicry.

Emotional mimicry, the imitation of others' emotion expressions, is related to increased interpersonal closeness and better interaction quality. Yet, little research has focused on the effect of face masks on emotional mimicry and none on (masked) child faces. To address this gap, we conducted an online experiment (N = 235, German sample, adult perceivers). Masks reduced emotion recognition accuracy for all expressions, except in the case of anger in masked child faces, where perceived anger was even increased. Perceived interpersonal closeness was reduced for masked happy and sad faces. For both child and adult expressers, masks reduced facial mimicry of happy expressions, with no mask effects for sadness and anger expression. A stronger mask effect on facial happiness mimicry of child faces was mediated by the degree of emotion recognition accuracy. Smiles shown by masked children were not recognized well, likely due to the absence of wrinkles around the eyes in child faces. Independent of masks, sadness shown by children was mimicked even more strongly than when shown by adults. These results provide evidence for facial mimicry of child expressions by adult perceivers and show that the effects of face masks on emotion communication may vary when children wear them.

Effectiveness of emotion regulation strategies measured by self-report and EMG as a result of strategy used, negative emotion strength and participants' baseline HRV.

We investigated how emotion regulation (ER) effectiveness-on both a self-reported rating as well as emotional expression (corrugator supercilii muscle activity) level-is affected by the characteristics of the situation (low vs. high negativity), the strategy used (reinterpretation, distraction, suppression, no regulation control condition) and individual dispositions (low vs. high baseline Heart Rate Variability) as well as their interaction. For this purpose, 54 adult women participated in a laboratory study. All the included factors significantly influenced both corrugator activity and appraisals of pictures' negativity (in specific experimental conditions). For example, for high HRV participants, (1) distraction, suppression and reinterpretation significantly decreased corrugator activity compared to the control condition, and (2) distraction decreased appraised picture negativity for high negativity photos. For low HRV participants, distraction and suppression were most effective in decreasing corrugator responses, while suppression was more effective than reinterpretation in decreasing perceived picture negativity in the high negativity condition. Subjectively reported effort and success in applying ER strategies were also dependent on manipulated and dispositional factors. Overall, our results lend support to the flexible emotion regulation framework, showing that emotion regulation effectiveness relies on situational context as well as individual dispositions and their interaction.

I looked at you, you looked at me, I smiled at you, you smiled at me-The impact of eye contact on emotional mimicry.

Eye contact is an essential element of human interaction and direct eye gaze has been shown to have effects on a range of attentional and cognitive processes. Specifically, direct eye contact evokes a positive affective reaction. As such, it has been proposed that obstructed eye contact reduces emotional mimicry (i.e., the imitation of our counterpart's emotions). So far, emotional mimicry research has used averted-gaze faces or unnaturally covered eyes (with black censor bars) to analyze the effect of eye contact on emotional mimicry. However, averted gaze can also signal disinterest/ disengagement and censor bars obscure eye-adjacent areas as well and hence impede emotion recognition. In the present study (N = 44), we used a more ecological valid approach by showing photos of actors who expressed either happiness, sadness, anger, or disgust while either wearing mirroring sunglasses that obstruct eye contact or clear glasses. The glasses covered only the direct eye region but not the brows, nose ridge, and cheeks. Our results confirm that participants were equally accurate in recognizing the emotions of their counterparts in both conditions (sunglasses vs. glasses). Further, in line with our hypotheses, participants felt closer to the targets and mimicked affiliative emotions more intensely when their counterparts wore glasses instead of sunglasses. For antagonistic emotions, we found the opposite pattern: Disgust mimicry, which was interpreted as an affective reaction rather than genuine mimicry, could be only found in the sunglasses condition. It may be that obstructed eye contact increased the negative impression of disgusted facial expressions and hence the negative feelings disgust faces evoked. The present study provides further evidence for the notion that eye contact is an important prerequisite for emotional mimicry and hence for smooth and satisfying social interactions.

The different shades of laughter: when do we laugh and when do we mimic other's laughter?

Laughter is an ambiguous phenomenon in response to both positive and negative events and a social signal that coordinates social interactions. We assessed (i) who laughs and why, and (ii) if the type of laughter and whether the observer approves of it impact on facial mimicry as a proxy for shared laughter. For this, 329 participants watched funny, schadenfreude and disgusting scenes and then saw individuals who purportedly reacted to each scene while participants' facial expressions were recorded and analysed. Participants laughed more in response to funny than in response to schadenfreude scenes and least in response to disgust scenes, and laughter within each scene could be explained both by situational perceptions of the scenes as well as by individual differences. Furthermore, others' laughter in response to funny scenes was perceived as more appropriate, elicited more closeness and more laughter mimicry than others' laughter in response to schadenfreude and especially in response to disgust scenes. Appropriateness and closeness as well as individual differences could explain laughter mimicry within each scene. This is in line with the notion that laughter is not per se an affiliative signal and that different types of laughter have distinct social implications. This article is part of the theme issue 'Cracking the laugh code: laughter through the lens of biology, psychology and neuroscience'.

Higher heart rate variability predicts better affective interaction quality in non-intimate social interactions.

Adaptive emotional responding is crucial for psychological well-being and the quality of social interactions. Resting heart rate variability (HRV), a measure of autonomic nervous system activity, has been suggested to index individual differences in emotion regulation (ER). As non-intimate social interactions require more regulatory efforts than intimate social interactions, we predicted that the association between HRV and affective interaction quality is moderated by the perceived intimacy of the exchange. Thus, we expected higher HRV to be particularly beneficial for affective interaction quality in non-intimate social interactions. Resting HRV was measured in the laboratory (N = 144). Subsequently, participants reported their affective interaction quality-as indicated by more positive and fewer negative emotions perceived in the self and the other-during an experience-sampling social interaction diary task. As predicted, in non-intimate interactions, individuals with higher HRV reported more positive and fewer negative emotions and perceived fewer negative emotions in their interaction partners. The results provide further insights into the relationship between HRV and emotional experiences during social interactions.

(Un)mask yourself! Effects of face masks on facial mimicry and emotion perception during the COVID-19 pandemic.

Face masks have been said to impact face-to-face interaction negatively. Yet, there is limited evidence on the degree to which partial face occlusion is detrimental to empathic processes such as emotion perception and facial mimicry. To address this question, we conducted an online experiment (N=200, U.K. sample) that assessed subjective ratings and facial expressions (mimicry) in response to masked and unmasked faces. Perceivers were able to recognise happiness and sadness in dynamic emotion expressions independent of (surgical) face masks. However, perceived emotion intensity and interpersonal closeness were reduced for masked faces. Facial mimicry, the perceiver's imitation of the expresser's emotional display, was reduced or absent in response to happy but preserved for sad mask-covered expressions. For happy target expressions, the face-mimicry link was partially mediated by perceived emotion intensity, supporting the idea that mimicry is influenced by context effects. Thus, these findings suggest that whether face masks impede emotion communication depends on the emotion expressed and the emotion-communication aspect of interest. With unprecedented changes in nonverbal communication brought about by the COVID-19 pandemic, this research marks a first contribution to our understanding of facial mimicry as an important social regulator during these times.

Laughing at funerals and frowning at weddings: Top-down influences of context-driven social judgments on emotional mimicry.

This research aimed to assess top-down effects of social judgments on (facial) emotional mimicry. Based on the mimicry as social regulator model (Hess & Fischer, 2013) and the notion that people can use emotion expressions as cues to an expresser's traits (Hareli & Hess, 2010), we predicted that participants judge expressers who show affectively deviant expressions more negatively, feel less close to them and, thus, show reduced mimicry. Participants saw smiles and sad expressions embedded in either a wedding or funeral scene (or neutral control). In Study 1, affectively deviant expressions were rated as inappropriate and led to less self-reported interpersonal closeness to the expresser. In Study 2, both happiness and sadness mimicry were affected by the normativeness of the expression. However, the specific effect varied. Participants mimicked both deviant and normative happy expressions only when they felt close to the expresser. However, in the case of deviant expressions, closeness was lower. When participants did not feel close to the expresser, their expression was neutral, that is, they did not mimic. Sadness was only mimicked when appropriate to the context, that is, when deemed a legitimate response and a valid appeal for help, regardless of closeness. In this sense, facial mimicry of sadness expression can be considered an empathic reaction. In sum, the present research shows strong evidence for a top-down effect of social judgments on mimicry. It further suggests that this effect differed as a function of emotion expression and the meaning and social appeal conveyed by that expression.
