Masks wearing off: Changing effects of face masks on trustworthiness over time.

During the global COVID-19 pandemic, the wearing of face masks became a common practice, raising questions about how masks affect perceptions of and behaviour towards others. Numerous studies have explored the impact of face masks on perceptions of trustworthiness, but results have been mixed and it remains unclear whether masks influence perceptions via their social meaning or their effects on facial appearance. In this study, Australian participants (N = 363) rated a series of faces which were either masked, unmasked, or occluded by a non-mask object (computer) in terms of perceived trustworthiness in 2020, 2022, or 2023. The apparent trustworthiness of unmasked faces remained stable across years, but masked faces were rated significantly more trustworthy in 2020 compared to 2022 and 2023. Furthermore, ratings of masked faces, but not unmasked faces, were correlated with participants' attitudes towards wearing masks. Faces occluded by a non-mask object were perceived to be less trustworthy than masked faces. Together, results strongly suggest the increase in perceived trustworthiness of masked faces reported in numerous studies conducted during COVID-19 were driven by positive social meanings around mask wearing rather than by their effect on facial appearance.

Knowledge of identity reduces variability in trait judgements across face images.

Faces vary from image to image, eliciting different judgements of traits and often different judgements of identity. Knowledge that two face images belong to the same person facilitates the processing of identity information across images, but it is unclear if this also applies to trait judgements. In this preregistered study, participants (N = 100) rated the same 340 face images on perceived trustworthiness, dominance, or attractiveness presented in randomised order and again later presented in sets consisting of the same identity. We also explored the role of implicit person theory beliefs in the variability of social judgements across images. We found that judgements of trustworthiness varied less when images were presented in sets consisting of the same identity than in randomised order and were more consistent for images presented later in a set than those presented earlier. However, knowledge of identity had little effect on perceptions of dominance and attractiveness. Finally, implicit person theory beliefs were not associated with variability in social judgements and did not account for effects of knowledge of identity. Our findings suggest that knowledge of identity and perceptual familiarity stabilises judgements of trustworthiness, but not perceptions of dominance and attractiveness.

Warmth and competence perceptions of key protagonists are associated with containment measures during the COVID-19 pandemic: Evidence from 35 countries.

It is crucial to understand why people comply with measures to contain viruses and their effects during pandemics. We provide evidence from 35 countries (Ntotal = 12,553) from 6 continents during the COVID-19 pandemic (between 2021 and 2022) obtained via cross-sectional surveys that the social perception of key protagonists on two basic dimensions-warmth and competence-plays a crucial role in shaping pandemic-related behaviors. Firstly, when asked in an open question format, heads of state, physicians, and protest movements were universally identified as key protagonists across countries. Secondly, multiple-group confirmatory factor analyses revealed that warmth and competence perceptions of these and other protagonists differed significantly within and between countries. Thirdly, internal meta-analyses showed that warmth and competence perceptions of heads of state, physicians, and protest movements were associated with support and opposition intentions, containment and prevention behaviors, as well as vaccination uptake. Our results have important implications for designing effective interventions to motivate desirable health outcomes and coping with future health crises and other global challenges.

Image variability and face matching.

This study investigates whether variability in perceived trait judgements disrupts our ability to match unfamiliar faces. In this preregistered study, 174 participants completed a face matching task where they were asked to indicate whether two ambient face images belonged to the same person or different people (17,748 total data points). Participants completed 51 match trials consisting of images of the same person that differed substantially on one trait (either trustworthiness, dominance or attractiveness) with minimal differences in the alternate traits. Participants also completed 51 mismatch trials which contained two photos of similar-looking individuals. We hypothesised that participants would make more errors on match trials when images differed in terms of attractiveness ratings than when they differed on trustworthiness or dominance. Contrary to expectations, images that differed in terms of attractiveness were matched most accurately, and there was no relationship between the extent of differences in attractiveness ratings and accuracy. There was some evidence that differences in perceived dominance and, to a lesser extent, trustworthiness were associated with lower face matching performance. However, these relationships were not significant when alternate traits were accounted for. The findings of our study suggest that face matching performance is largely robust against variation in trait judgements.

Effects of Face Masks on Person Perception.

As face masks have become more commonplace in many regions due to COVID-19, concerns have been raised about their effects on the perception of mask wearers and social cohesion more broadly, including racial profiling. In two studies we examined the effects of masks on social judgments of mask wearers, and whether masks have different effects on judgments of Black and White faces. Participants rated 20 Black and 20 White faces with and without masks on trustworthiness/approachability (Studies 1 and 2) and on dominance/competence and attractiveness (Study 2). In both studies masks increased perceived trustworthiness and reduced the effect of face race on judgments. Masks also increased perceived attractiveness, but had no effect on the perception of dominance/competence. Overall, this study found no negative effects of face masks on judgments of mask wearers, though further research is needed.

Within-Person Variability in First Impressions From Faces.

Perceptions of an individual can change dramatically across different images of their face. Questions remain as to whether some traits are more sensitive to image variability than others. To investigate this issue, we constructed a database of 340 naturalistic images consisting of 20 photos of 17 individuals. In this preregistered study, 95 participants rated all 340 images on one of three traits: trustworthiness, dominance, or attractiveness. Across images, participants' trustworthiness ratings tended to vary more than dominance, which in turn varied more than attractiveness; however, the relative differences between traits depended on the identity in question. Importantly, despite the variability in ratings within identities, there were substantial differences between individuals, suggesting that these trait judgements are based to some degree on relatively invariant facial characteristics. We found greater between-identity variability for attractiveness judgements compared to trustworthiness and dominance. Future research should further investigate the extent to which each trait dimension is tied to the identity of the faces.

Stereotype content and morality: How competence and warmth arise from morally significant interactions.

Stereotypes about many groups fall along two dimensions, one relating to agency/competence and the other morality/warmth. This paper integrates research and theory on stereotype contents and mind perception to explore how stereotypes of competence and warmth are linked to perceptions of moral agency and patiency. Competence identifies the moral agent, and warmth both identifies the moral patient and describes the moral valence of the interaction. In two experimental tests, a simple animated film showing circles and squares interacting in various ways elicited predicted competence and warmth stereotypes that tracked perceived moral valence. Integrating stereotype contents and mind perception literatures offers new ways to think about the origins, functions, and dynamics between dimensions of stereotype content.

Trait self-awareness predicts perceptions of choice meaningfulness in a decision-making task.

OBJECTIVE: Seminal theorists such as Erikson, Bruner, Frankl and Rogers have underscored the importance of meaning in psychological life. However contemporary scholars interested in meaning have noted that further investigation of the individual differences associated with meaning-making is still needed. In the present study we explored whether individual differences in trait self-awareness were associated with perceptions of choice meaningfulness in a decision-making task. RESULTS: All participants engaged in a decision-making task wherein they were asked to choose their preferred painting out of pairs of sequentially presented abstract paintings. Participants in the experimental condition were provided with feedback that their choices had been diagnostic of important personality characteristics whereas those in the control condition were not. All participants were then prompted to reflect on their choices before rating the subjective meaningfulness that they associated with their choices and completing measures to assess trait self-awareness. As anticipated, persons with higher levels of trait self-awareness tended to seek out and find more meaning compared to those lower in trait self-awareness. However contrary to expectations, feedback about the self-relevance of choices did not moderate perceptions of choice meaningfulness. Implications of these findings as well as directions for future research are also discussed.

Facial First Impressions Across Culture: Data-Driven Modeling of Chinese and British Perceivers' Unconstrained Facial Impressions.

People form first impressions from facial appearance rapidly, and these impressions can have considerable social and economic consequences. Three dimensions can explain Western perceivers' impressions of Caucasian faces: approachability, youthful-attractiveness, and dominance. Impressions along these dimensions are theorized to be based on adaptive cues to threat detection or sexual selection, making it likely that they are universal. We tested whether the same dimensions of facial impressions emerge across culture by building data-driven models of first impressions of Asian and Caucasian faces derived from Chinese and British perceivers' unconstrained judgments. We then cross-validated the dimensions with computer-generated average images. We found strong evidence for common approachability and youthful-attractiveness dimensions across perceiver and face race, with some evidence of a third dimension akin to capability. The models explained ~75% of the variance in facial impressions. In general, the findings demonstrate substantial cross-cultural agreement in facial impressions, especially on the most salient dimensions.

The Effect of Trait Self-Awareness, Self-Reflection, and Perceptions of Choice Meaningfulness on Indicators of Social Identity within a Decision-Making Context.

Theorists operating from within a narrative identity framework have suggested that self-reflective reasoning plays a central role in the development of the self. Typically, however, narrative identity researchers have investigated this relationship using correlational rather than experimental methods. In the present study, leveraging on a classic research paradigm from within the social identity literature we developed an experiment to test the extent to which self-reflection might have a causal impact on the self-concept within a decision-making context. In a minimal group paradigm participants were prompted to reflect on their painting choices either before or after allocating points to in-group∖ out-group members. As anticipated, self-reflection augmented social identification, but only when participants felt their choices were personally meaningful. Participants who reasoned about their choices and felt they were subjectively meaningful showed stronger similarity and liking for in-group members compared to those who did not reflect on their choices or found them to be subjectively meaningless. Hence, reflecting on and finding meaning in one's choices may be an important step in linking behavior with in-group identification and thus the self-concept in turn. The absence of any effects on in-group favoritism (a third indicator of social identification measured) as well as implications of the study's findings for self-perception, cognitive dissonance and social identity processes are also discussed.

Integrating social and facial models of person perception: Converging and diverging dimensions.

Models of first impressions from faces have consistently found two underlying dimensions of trustworthiness and dominance. These dimensions show apparent parallels to social psychological models of inter-group perception that describe dimensions of warmth (cf. trustworthiness) and competence (cf. dominance), and it has been suggested that they reflect universal dimensions of social cognition. We investigated whether the dimensions from face and inter-group social perception models are indeed equivalent by evaluating first impressions of faces. Across four studies with differing methods we consistently found that while perceptions of trustworthiness and warmth were closely related, perceptions of dominance and competence were less strongly related. Taken together, our results demonstrate strong similarity on the first dimension across facial and social models, with less similarity on the second dimension. We suggest that facial impressions of competence and dominance may represent different routes to judging a stranger's capability to help or harm.

The Association Between Men's Sexist Attitudes and Facial Hair.

Facial hair, like many masculine secondary sexual traits, plays a significant role in perceptions of an array of sociosexual traits in men. While there is consensus that beards enhance perceptions of masculinity, age, social dominance, and aggressiveness, the perceived attractiveness of facial hair varies greatly across women. Given the ease with which facial hair can be groomed and removed entirely, why should some men retain beards and others choose to remove them? We hypothesized that men with relatively sexist attitudes would be more likely to allow their facial hair to grow than men with less sexist attitudes. Men from the USA (n = 223) and India (n = 309) completed an online survey measuring demographic variables, ambivalent sexism, and facial hair status. After controlling for demographic variables, men with facial hair were significantly higher in hostile sexism than clean-shaven men; hostile sexism was a significant predictor of facial hair status over and above demographic variables; and facial hair was more frequent among ambivalent and hostile sexists than among benevolent and non-sexists. It is suggested that sexist men choose to grow facial hair because it maximizes sexual dimorphism and augments perceived masculinity and dominance.

Face gender and stereotypicality influence facial trait evaluation: Counter-stereotypical female faces are negatively evaluated.

The facial first impressions literature has focused on trait dimensions, with less research on how social categories (like gender) may influence first impressions of faces. Yet, social psychological studies have shown the importance of categories like gender in the evaluation of behaviour. We investigated whether face gender affects the positive or negative evaluation of faces in terms of first impressions. In Study 1, we manipulated facial gender stereotypicality, and in Study 2, facial trustworthiness or dominance, and examined the valence of resulting spontaneous descriptions of male and female faces. For both male and female participants, counter-stereotypical (masculine or dominant looking), female faces were perceived more negatively than facially stereotypical male or female faces. In Study 3, we examined how facial dominance and trustworthiness affected rated valence across 1,000 male and female ambient face images, and replicated the finding that dominance is more negatively evaluated for female faces. In Study 4, the same effect was found with short stimulus presentations. These findings integrate the facial first impressions literature with evaluative differences based on social categories.

Social inferences from faces: ambient images generate a three-dimensional model.

Three experiments are presented that investigate the two-dimensional valence/trustworthiness by dominance model of social inferences from faces (Oosterhof & Todorov, 2008). Experiment 1 used image averaging and morphing techniques to demonstrate that consistent facial cues subserve a range of social inferences, even in a highly variable sample of 1000 ambient images (images that are intended to be representative of those encountered in everyday life, see Jenkins, White, Van Montfort, & Burton, 2011). Experiment 2 then tested Oosterhof and Todorov's two-dimensional model on this extensive sample of face images. The original two dimensions were replicated and a novel 'youthful-attractiveness' factor also emerged. Experiment 3 successfully cross-validated the three-dimensional model using face averages directly constructed from the factor scores. These findings highlight the utility of the original trustworthiness and dominance dimensions, but also underscore the need to utilise varied face stimuli: with a more realistically diverse set of face images, social inferences from faces show a more elaborate underlying structure than hitherto suggested.

Is the igeneration a 'we' generation? Social networking use among 9- to 13-year-olds and belonging.

Research suggests that online communication is associated with increased closeness to friends and friendship quality. Children under 13 years of age are increasingly using social networking sites (SNSs), but research with this younger age group is scarce. This study examined the relationship between SNS use and feelings of belonging among children aged 9-13 years. A self-report questionnaire was administered to 443 children (48.98% boys), asking about their SNS use and their sense of belonging to their friendship group. SNS users reported a stronger sense of belonging to their friendship group than non-users, but this was found only among older boys. Furthermore, among boy SNS users, a positive linear relationship was found between the intensity of usage and feelings of belonging. No significant relationships were found for girls. These findings suggest that boys who use these sites are gaining friendship benefits over and above those boys who are non-users or low-intensity users. Longitudinal studies should investigate the causal relationships between SNS use and social effects within this age group.

Contentment to resentment: Variation in stereotype content across status systems.

This paper describes an integration of the stereotype content model with social identity theory in which we theorise links between the legitimacy and stability of status relations between groups on the one hand, and stereotypes of warmth and competence on the other. Warmth stereotypes associate with the perceived morality of inequalities, so we reason that high and low status groups are more differentiated in warmth in illegitimate status systems. Also, stereotypes of competence explain status differences, so differences in stereotypical competence may be more pronounced when status is stable rather than unstable. Across two experiments high and low status groups were more sharply differentiated in warmth in illegitimate than legitimate status systems, as predicted. The effect of stability on competence was less clear, as groups were clearly differentiated in competence in all status systems. Implications for the roles of warmth and competence stereotypes in social change are discussed.

Social status and the pursuit of positive social identity: Systematic domains of intergroup differentiation and discrimination for high- and low- status groups.

Research on intergroup discrimination has focused on the cognitive and motivational mechanisms involved, but the role of stereotype content has been neglected. Drawing on social identity theory and stereotype content research, the current studies investigated the role of stereotype content in intergroup differentiation and discrimination. Across two studies, students from high- and low-status groups differentiated themselves positively on stereotypes of competence and warmth respectively, and in allocations of resources in domains relevant to competence (academics, research) and warmth (sports, community outreach). Furthermore, there was evidence that discrimination by high- and low-status groups was driven by their respective stereotypes of competence and warmth. It is argued that stereotypes of competence and warmth, derived from status and power relations between groups, define the domains in which groups pursue positively distinct identities.
