People routinely use facial expressions to communicate successfully and to regulate other's behaviour, yet modelling the form and meaning of these facial behaviours has proven surprisingly complex. One reason for this difficulty may lie in an over-reliance on the assumptions inherent in existing theories of facial expression - specifically that (1) there is a putative set of facial expressions that signal an internal state of emotion, (2) patterns of facial movement have been empirically linked to the prototypical emotions in this set, and (3) static, non-social, posed images from convenience samples are adequate to validate the first two assumptions. These assumptions have guided the creation of datasets, which are then used to train unrepresentative computational models of facial expression.

Background: Social and familial consequences of pacifier use remain poorly understood. The present study attempts to shed more light on the characteristics of parents using pacifiers with their infants and to explore how pacifier use affects perceptions of infant emotionality, maternal stress, and parental efficacy.

Methods: The study sample consisted of 428 mothers (range: 17-49 years) of infants (0-36 months) who completed a comprehensive questionnaire assessing infant and parent characteristics as well as parenting practices and pacifier use.

Children with facial differences, such as repaired cleft lip and palate (CLP), may present with reduced capacity for sensorimotor simulation, particularly in the form of facial mimicry. This study examined whether facial mimicry, emotion recognition, and empathy skills are reduced in children with CLP when compared with sex/age-matched controls. A case-control design was utilized.

Objective: To examine the facial movements children with cleft lip and palate (CLP) employ to express basic emotions. Ability of observers to interpret facial expressions of children with CLP was also considered.

Design: Prospective case-control design.

Face masks that prevent disease transmission obscure facial expressions, impairing nonverbal communication. We assessed the impact of lower (masks) and upper (sunglasses) face coverings on emotional valence judgments of clearly valenced (fearful, happy) and ambiguously valenced (surprised) expressions, the latter of which have both positive and negative meaning. Masks, but not sunglasses, impaired judgments of clearly valenced expressions compared to faces without coverings.

Cultural differences in emotion expression, experience, and regulation can cause misunderstandings with lasting effects on interpersonal, intergroup, and international relations. A full account of the factors responsible for the emergence of different cultures of emotion is therefore urgent. Here we propose that the ancestral diversity of regions of the world, determined by colonization and sometimes forced migration of humans over centuries, explains significant variation in cultures of emotion.

In the United States the color red has come to represent the Republican party, and blue the Democratic party, in maps of voting patterns. Here we test the hypothesis that voting maps dichotomized into red and blue states leads people to overestimate political polarization compared to maps in which states are represented with continuous gradations of color. We also tested whether any polarizing effect is due to partisan semantic associations with red and blue, or if alternative hues produce similar effects.

Historically, exposure to dissimilar others ("strangers") was a physiologically arousing event-resulting in avoidance, distrust, and even conflict. Despite this, contemporary migration patterns are increasing intergroup contact. What gives rise to an individual's ability to regulate their arousal such that social engagement with outgroup members is possible? We propose that cultural practices that evolve in ancestrally diverse, compared to ancestrally homogeneous, societies provide more opportunities for society members to engage in emotion regulation.

Cooperating with another person requires communicating intentions and coordinating behavior. People often accomplish these tasks using spoken language, but verbal communication is not always available. Here, we test the hypothesis that, to establish successful cooperative interaction, people compensate for the temporary loss of one means, verbal communication, by amplifying another, namely nonverbal expressive synchrony.

Unlabelled: According to the familiar axiom, the eyes are the window to the soul. However, wearing masks to prevent the spread of viruses such as COVID-19 involves obscuring a large portion of the face. Do the eyes carry sufficient information to allow for the accurate perception of emotions in dynamic expressions obscured by masks? What about the perception of the meanings of specific smiles? We addressed these questions in two studies.

Smiles are nonverbal signals that convey social information and influence the social behavior of recipients, but the precise form and social function of a smile can be variable. In previous work, we have proposed that there are at least three physically distinct types of smiles associated with specific social functions: reward smiles signal positive affect and reinforce desired behavior; affiliation smiles signal non-threat and promote peaceful social interactions; dominance smiles signal feelings of superiority and are used to negotiate status hierarchies. The present work advances the science of the smile by addressing a number of questions that directly arise from this smile typology.

We investigated the effects of different types of smiles on the perception of uncooperative or untrustworthy behaviour. In five studies, participants assigned to one group played an economic game with a representative of another group. In an initial round, the representative acted uncooperatively by favouring their group and then displayed a dominance, reward, or affiliation smile.

Research over the past decades has demonstrated the explanatory power of emotions, feelings, motivations, moods, and other affective processes when trying to understand and predict how we think and behave. In this consensus article, we ask: has the increasingly recognized impact of affective phenomena ushered in a new era, the era of affectivism?

Fiction reading experience affects emotion recognition abilities, yet the causal link remains underspecified. Current theory suggests fiction reading promotes the simulation of fictional minds, which supports emotion recognition skills. We examine the extent to which contextualized statistical experience with emotion category labels in language is associated with emotion recognition.

Cultural context shapes individuals' valuation of emotions. Although studies have documented cultural differences in beliefs about the utility of negative emotions, little is known about how such cultural valuation is associated with physiological stress responses. In the present work, we examined whether East Asians and European Americans differ in how they value nervousness in a demanding situation and whether such valuation predicts acute cardiovascular responses.

In most primates, eye contact is an implicit signal of threat, and often connotes social status and imminent physical aggression. However, in humans and some of the gregarious nonhuman primates, eye contact is tolerated more and may be used to communicate other emotional and mental states. What accounts for the variation in this critical social cue across primate species? We crowd-sourced primatologists and found a strong linear relationship between eye contact tolerance and primate social structure such that eye contact tolerance increased as social structures become more egalitarian.

Background And Objectives: Negative interpretation biases are postulated to play etiological and maintaining roles in social anxiety (SA). However, empirical support for interpretation biases of facial expression in SA is inconsistent. Given the importance of signals of (dis)approval in SA, our objective was to examine whether SA is associated with enhanced sensitivity to such signals especially following exclusion.

Spontaneous facial mimicry is modulated by many factors, and often needs to be suppressed to comply with social norms. The neural basis for the inhibition of facial mimicry was investigated in a combined functional magnetic resonance imaging and electromyography study in 39 healthy participants. In an operant conditioning paradigm, face identities were associated with reward or punishment and were later shown expressing dynamic smiles and anger expressions.

Sometimes risk involves taking actions that in and of themselves elicit emotion, often fearful emotions. Across two studies we test the hypothesis that preventing facial actions associated with fear and anxiety responses during a risky decision task leads to greater risk taking. We first demonstrate that while performing the balloon analogue risk task (Lejuez et al.

Human emotional behavior varies across cultures. Smiling at a passing stranger on the street may seem perfectly normal in one culture and profoundly strange or even suspicious in another. What are the origins of cultural differences in emotional expression, communication, and regulation? We review new evidence in favor of one answer to this question.

One of the biggest challenges in the study of emotion-cognition interaction is addressing the question of whether and how emotions influence processes of perception as distinct from other higher-level cognitive processes. Most theories of emotion agree that an emotion episode begins with a sensory experience - such as a visual percept - that elicits a cascade of affective, cognitive, physiological, and/or behavioural responses (the ordering and inclusion of those latter components being forever debated). However, for decades, a subset of philosophers and scientists have suggested that the presumed perception → emotion relationship is in fact bidirectional, with emotion also altering the perceptual process.

The present research comprises six experiments that investigated racial biases in the perception of positive emotional expressions. In an initial study, we demonstrated that White participants distinguished more in their happiness ratings of Duchenne ("true") and non-Duchenne ("false") smiles on White compared with Black faces (Experiment 1). In a subsequent study we replicated this effect using a different set of stimuli and non-Black participants (Experiment 2).

Recognising a facial expression is more difficult when the expresser's body conveys incongruent affect. Existing research has documented such interference for universally recognisable bodily expressions. However, it remains unknown whether learned, conventional gestures can interfere with facial expression processing.

Recent findings demonstrate that heterogeneity of long-history migration predicts present-day emotion behaviors and norms. Residents of countries characterized by high ancestral diversity display emotion expressions that are easier to decode by observers, endorse norms of higher emotion expressivity, and smile more in response to certain stimuli than residents of countries that lack ancestral diversity. We build on the extant findings and investigate historical heterogeneity as a predictor of daily smiling, laughter, and positive emotion across the world's countries and the states of the United States.
