What will we judge a book by its cover?-Content analysis of face perception in a Chinese sample

People can perceive various information from faces. Most of previous studies of face perception only focused on one of attributes, such as gender, expression, personality etc., the whole picture of face perception is far from clear. Therefore, the present study recruited Chinese participants to provide spontaneous descriptions of unfamiliar Chinese faces without any constraints of content. It turned out that descriptions employed a broad spectrum of descriptors, as well as a consistent pattern across different identities: descriptions that incorporated psychological characteristics were most prevalent, whereas mentions of physiological attributes generally occurred earlier in the description than other types of descriptive vocabulary. These results underscore the special role of free description analysis in revealing the panorama of face perception, where perceivers swiftly infer a plenty of character traits in an organized way, ultimately forming a comprehensive impression of others.

Words matter when inferring emotions: a conceptual replication and extension

It is long known that facial configurations play a critical role when inferring mental and emotional states from others. Nevertheless, there is still a scientific debate on how we infer emotions from facial configurations. The theory of constructed emotion (TCE) suggests that we may infer different emotions from the same facial configuration, depending on the context (e.g. provided by visual and lexical cues) in which they are perceived. For instance, a recent study found that participants were more accurate in inferring mental and emotional states across three different datasets (i.e. RMET, static and dynamic emojis) when words were provided (i.e. forced-choice task), compared to when they were not (i.e. free-labelling task), suggesting that words serve as contexts that modulate the inference from facial configurations. The goal of the current within-subject study was to replicate and extend these findings by adding a fourth dataset (KDEF-dyn), consisting of morphed human faces (to increase the ecological validity). Replicating previous findings, we observed that words increased accuracy across the three (previously used) datasets, an effect that was also observed for the facial morphed stimuli. Our findings are in line with the TCE, providing support for the importance of contextual verbal cues in emotion perception.

Personality Across World Regions Predicts Variability in the Structure of Face Impressions

Research on face impressions has often focused on a fixed, universal architecture, treating regional variability as noise. Here, we demonstrated a crucial yet neglected role of cultural learning processes in forming face impressions. In Study 1, we found that variability in the structure of adult perceivers' face impressions across 42 world regions (N = 287,178) could be explained by variability in the actual personality structure of people living in those regions. In Study 2, data from 232 world regions (N = 307,136) revealed that adult perceivers use the actual personality structure learned from their local environment to form lay beliefs about personality, and these beliefs in turn support the structure of perceivers' face impressions. Together, these results suggest that people form face impressions on the basis of a conceptual understanding of personality structure that they have come to learn from their regional environment. The findings suggest a need for greater attention to the regional and cultural specificity of face impressions.

Cross-cultural perception of female facial appearance: A multi-ethnic and multi-centre study

Humans extract and use information from the face in assessments of physical appearance. Previous research indicates high agreement about facial attractiveness within and between cultures. However, the use of a narrow age range for facial stimuli, limitations due to unidirectional cross-cultural comparisons, and technical challenges have prevented definitive conclusions about the universality of face perception. In the present study, we imaged the faces of women aged 20 to 69 years in five locations (China, France, India, Japan, and South Africa) and secured age, attractiveness, and health assessments on continuous scales (0-100) from female and male raters (20-66 years) within and across ethnicity. In total, 180 images (36 of each ethnicity) were assessed by 600 raters (120 of each ethnicity), recruited in study centres in the five locations. Linear mixed model analysis revealed main and interaction effects of assessor ethnicity, assessor gender, and photographed participant ("face") ethnicity on age, attractiveness, and health assessments. Thus, differences in judgments of female facial appearance depend on the ethnicity of the photographed person, the ethnicity of the assessor, and whether the assessor is female or male. Facial age assessments correlated negatively with attractiveness and health assessments. Collectively, these findings provide evidence of cross-cultural variation in assessments of age, and even more of attractiveness, and health, indicating plasticity in perception of female facial appearance across cultures, although the decline in attractiveness and health assessments with age is universally found.

Facial Attractiveness of Sisters of Thai Gay Men and Sao Praphet Song

Androphilia refers to sexual attraction toward adult males. Androphilic males' female genetic relatives might offset the fitness cost of androphilia by having elevated numbers of offspring. Increased attractiveness relative to other women may enable these females to marry up the social hierarchy, providing greater access to resources to support more offspring. In Thailand, there is a marked status hierarchy and male androphiles are highly visible - identifying as gay men or as a third gender known as sao praphet song. Thus, a field experiment was conducted in which 208 heterosexual men rated the facial attractiveness of 25 sisters of Thai gay men or sao praphet song and 25 comparison women with no known same-sex attracted relatives. Contrary to the prediction, the comparison group was rated as more attractive than the sisters, casting doubt on hypotheses that posit greater attractiveness of female relatives of male androphiles as a proximate mechanism facilitating the evolutionary maintenance of genes influencing male androphilia. Also, men from rural areas rated the women, regardless of group, as more attractive than men from urban areas, consistent with some prior studies showing rural-urban differences in perceptions of attractiveness.
