Symmetry in Motion: Perception of Attractiveness Changes with Facial Movement

Facial symmetry is an index of developmental stability and shows a positive correlation with attractiveness assessment. However, the appearance of one’s facial symmetry is not always static and may change when there is facial movement while a person is speaking. This study examined whether viewing a dynamic image of a person speaking (where facial symmetry may alter) would elicit a different perception of attractiveness than viewing a static image of that person as a still photo. We examined changes in both measured and perceived facial symmetry in relation to attractiveness perception. We found that when facial movements created an appearance of overall greater facial symmetry while a person was speaking in a video, the person was rated as being more attractive than as a still photo. Likewise, those with facial movements measured and perceived as less symmetrical while speaking were rated as less attractive in a video clip than still photo. By examining the perception of faces in motion as we typically encounter others in real life rather than considering only static photos, we have extended the ecological validity of the study of the perception of bilateral symmetry in humans as it relates to attractiveness.     

Beautiful stereotypes: the relationship between physical attractiveness and mixed race identity

The idea that mixed race individuals are physically attractive is a commonly accepted stereotype. Past research in which whites (Australians and British) and Asians (Japanese) were asked to rate the attractiveness of a racially heterogeneous group of faces has shown that mixed race phenotype was judged the most attractive. In this study, I examine whether there is empirical evidence for this Biracial Beauty Stereotype in the United States. Using the data from the National Longitudinal Survey of Adolescent Health, I examine self and interview ratings of respondents' physical attractiveness and, in an extension of the previous literature, conduct multinomial logistic regressions to ascertain whether level of attractiveness is associated with different racial identification choices for mixed race individuals. My results indicate that there is in fact a belief in mixed race individuals' superior beauty in America; but, with regard to identity, beauty is not associated with identity for all mixed race groups.     

Attention during Visual Preference Tasks: Relation to Caregiving and Face Recognition

This research examined how caregiver experience (female primary caregiver or distributed caregiving with mom and dad) influenced 10‐, 14‐, and 16‐month‐olds’ visual preferences and attention toward internal facial features of female–male face pairs, and how these behaviors related to novelty preferences in a face recognition task and speed and accuracy on a visual search task. In the visual preference task, infants visually preferred male faces, regardless of caregiver experience. Despite similarities in visual preferences, infants’ attention toward females and males’ internal facial features was related for infants with distributed caregiving only. Infants’ performance across face processing tasks most often correlated for those with female primary caregivers. Results further our understanding of how infants with female primary caregivers display specialized processing of female faces, and how infants with distributed caregiving show similarities in their attention to female and male facial features.     

Sensitivity to “Bad Genes” and the Anomalous Face Overgeneralization Effect: Cue Validity, Cue Utilization, and Accuracy in Judging Intelligence and Health

The bad genes and anomalous face overgeneralization accounts of facial preferences were tested by examining cue validity, cue utilization, and accuracy in judging health and intelligence from faces in the upper and lower halves of the distributions of attractiveness and its components: averageness, symmetry, and masculinity. Consistent with the bad genes hypothesis, facial attractiveness, averageness, symmetry, and male face masculinity each provided valid cues to intelligence and/or health for faces in the lower but not the upper halves of the distributions of these facial qualities. Consistent with the anomalous face overgeneralization hypothesis, attractiveness and its components were utilized as cues not only for faces in the lower halves of the distributions, but also for those in the upper halves. Intelligence and health were judged accurately for faces in the lower but not the upper half of the attractiveness distribution, and attractiveness mediated this accuracy at all ages except adolescence. Since adolescence is the prime mating age, the latter finding raises questions about the utility of attractiveness as an evolved mechanism to ensure the selection of high quality mates.     

Fear Attenuated and Affection Augmented: Male Self-Presentation in a Romantic Context

We investigated whether males use facial behavior strategically in order to increase their desirability as romantic partners. Participants were led to believe that a female research assistant who was either attractive or unattractive was observing them. Their task was to watch three short films: an excerpt from a horror film, a video of infants, and a neutral film. Males who thought they were being observed by the attractive assistant frowned less (AU4) while watching the horror film and smiled more (AU12, with and without AU6) while watching the infant film. Assistant attractiveness did not affect males’ facial behavior while they were watching the neutral film.     

Faces Attract Infants' Attention in Complex Displays

Infant's face preferences have previously been assessed in displays containing 1 or 2 faces. Here we present 6‐month‐old infants with a complex visual array containing faces among multiple visual objects. Despite the competing objects, infants direct their first saccade toward faces more frequently than expected by chance (Experiment 1). The attention‐grabbing effect of faces is not selective to upright faces (Experiment 2) but does require the presence of internal facial elements, as faces whose interior has been phase‐scrambled did not attract infants' attention (Experiment 3). On the contrary, when the number of fixations is considered, upright faces are scanned more extensively than both inverted and phase‐scrambled faces. The difference in selectivity between the first look measure and the fixation count measure is discussed in light of a distinction between attention‐grabbing and attention‐holding mechanisms.     

The Stability of Facial Attractiveness: Is It What You’ve Got or What You Do with It?

Physical attractiveness is suggested to be an indicator of biological quality and therefore should be stable. However, transient factors such as gaze direction and facial expression affect facial attractiveness, suggesting it is not. We compared the relative importance of variation between faces with variation within faces due to facial expressions. 128 participants viewed photographs of 14 men and 16 women displaying the six basic facial expressions (anger, disgust, fear, happiness, sadness, surprise) and a neutral expression. Each rater saw each model only once with a randomly chosen expression. The effect of expressions on attractiveness was similar in male and female faces, although several expressions were not significantly different from each other. Identity was 2.2 times as important as emotion in attractiveness for both male and female pictures, suggesting that attractiveness is stable. Since the hard tissues of the face are unchangeable, people may still be able to perceive facial structure whatever expression the face is displaying, and still make attractiveness judgements based on structural cues.     

Baby talk to the babyfaced

The power of an infantile appearance to elicit baby talk was investigated by assessing the use of baby talk in task instructions to four-year-old children, who were portrayed as either relatively babyfaced or maturefaced. Men and women taught two tasks to a randomly selected boy or girl via a telephone conversation after being shown a photograph, which presumably depicted the child whom they were instructing. Paralleling facial differences between babies and adults, babyfaced children had rounder faces, larger eyes, thinner eyebrows, and smaller noses than the maturefaced. As predicted, adults used more baby talk when instructing babyfaced than maturefaced children. This effect was manifested in linguistic indicators of baby talk (slow timing and high clarification, simplification, and attention maintenance), as well as in paralinguistic indicators of baby talk (high pitch and changing intonation). The receipt of linguistic baby talk, in turn, facilitated the child's ability to choose a card which matched the one being described. The fact that facial babyishness influenced baby talk even when baby- and maturefaced children were equated in age, attractiveness, and perceived competence suggests that a small approximation to the craniofacial qualities that distinguish infants from adults may in and of itself be sufficient to elicit this speech register.This research was supported by NIMH grant #BSR5 R01 MH42684 to the first author. The authors would like to express their appreciation to the Brandeis University and Wellesley College Daycare Centers for their cooperation in this research.

People Automatically Extract Infants’ Sex from Faces

People can reliably distinguish the sex of faces across age groups. Rates of accuracy are lower for infants, however, likely because they lack the pronounced sexually dimorphic features that develop during puberty. Given that previous research has shown that perceivers categorize adult sex automatically, we wondered whether this would extend to the faces of infants for whom sex is less legible. We tested this using a semantic priming paradigm in which infant faces preceded the categorization of stereotypically male and female names. Results showed that participants categorized the sex of male names significantly faster following perceptions of male versus female infant faces (though female faces did not significantly facilitate the processing of female names). The asymmetry in interference for male but not female faces supports evidence for a male default in conceptions of sex among infants previously found for adults. Individuals may therefore process sex automatically in the absence of overt cues (e.g., post-pubertal sexually dimorphic features or stereotypical clothing), providing additional evidence for the depth and flexibility of social categorization.     

Mating strategies of young women: role of physical attractiveness

The female physical attractiveness stereotype has been reported to contain both desirable (sociable, poised, interesting) and undesirable (snobbish, likely to request divorce and have extra-marital affairs) personal qualities. To investigate whether such an attractiveness stereotype is cross-cultural, I asked men and women from Azore Island, Guinea-Bissau, Indonesia, and the U.S. to judge the attractiveness of female figures differing in body weight and waist-to-hip ratio (WHR) and to rank these figures according to perceived personal attributes. There was a strong cross-cultural consensus for attractiveness; figures with low WHR were judged to be more attractive than figures with high WHR within each weight category. Participants also judged attractive figures as less faithful than less-attractive figures. To explore the basis of a possible 'darker side ' of the attractiveness stereotype, behavior tactics of young U.S. women were examined. Compared to women with high WHRs, low-WHR women reported engaging in more flirting to make dates jealous, suggesting some truth to the attractiveness stereotype. Taken together, these findings suggest that female attractiveness influences the type of mating strategies employed by women.     

A Smile Enhances 3‐Month‐Olds’ Recognition of an Individual Face

Recent studies demonstrated that in adults and children recognition of face identity and facial expression mutually interact ( Bate, Haslam, & Hodgson, 2009 ; Spangler, Schwarzer, Korell, & Maier‐Karius, 2010 ). Here, using a familiarization paradigm, we explored the relation between these processes in early infancy, investigating whether 3‐month‐old infants’ ability to recognize an individual face is affected by the positive (happiness) or neutral emotional expression displayed. Results indicated that infants’ face recognition appears enhanced when faces display a happy emotional expression, suggesting the presence of a mutual interaction between face identity and emotion recognition as early as 3 months of age.     

Free Viewing Gaze Behavior in Infants and Adults

The current study investigated age differences in free viewing gaze behavior. Adults and 6‐, 9‐, 12‐, and 24‐month‐old infants watched a 60‐sec Sesame Street video clip while their eye movements were recorded. Adults displayed high intersubject consistency in eye movements; they tended to fixate the same places at the same. Infants showed weaker consistency between observers and intersubject consistency increased with age. Across age groups, the influence of both bottom‐up features (fixating visually salient areas) and top‐down features (looking at faces) increased. Moreover, individual differences in fixating bottom‐up and top‐down features predicted whether infants’ eye movements were consistent with those of adults, even when controlling for age. However, this relation was moderated by the number of faces available in the scene, suggesting that the development of adult‐like viewing involves learning when to prioritize looking at bottom‐up and top‐down features.     

Renaissance beauty = Today’s ugly: What appearance factors determine attractiveness judgments?

ABSTRACT

By comparing photos of portraits of the faces of Renaissance courtesans to photos of attractive contemporary women’s faces this study estimates the importance of sociocultural factors in the personal perception of faces. Physical attractiveness is an important causal factor in choosing a sex partner, so the difference between averaged attractiveness judgments, a focus of attractiveness research, and individual attractiveness judgment, most relevant to choosing a sex partner, is important. Except for modesty and faithfulness, 13 normally attractive contemporary models were rated much more positively by college student participants (N = 189) than were eight celebrated Renaissance courtesans, both in attractiveness (contemporary stimuli 63%; Renaissance courtesans 31%) and in personality traits. All of the Renaissance courtesan trait ratings showed more variability than the contemporary stimuli. This study supports the view that once a relatively low baseline level of biological attractiveness is surpassed, latent and explicit sociocultural factors, culturally relative gender role appearance expectations, culturally relative aesthetic judgment factors, individual differences, and interpersonal dynamics are major determining factors of judgments of pretty and/or beautiful showing large subcultural and cultural individual differences. Pretty and beautiful may be discrete concepts, with beautiful strongly culturally determined. These data suggest that sociocultural and subcultural factors are important determiners of attractiveness.     

The Relationship Between Processing Facial Identity and Emotional Expression in 8‐Month‐Old Infants

In Experiment 1, it was investigated whether infants process facial identity and emotional expression independently or in conjunction with one another. Eight‐month‐old infants were habituated to two upright or two inverted faces varying in facial identity and emotional expression. Infants were tested with a habituation face, a switch face, and a novel face. In the switch faces, a new combination of identity and emotional expression was presented. The results show that infants differentiated between switch and habituation faces only in the upright condition but not in the inverted condition. Experiment 2 provides evidence that infants’ nonresponse in the inverted condition can be attributed to their independent processing of facial identity and emotional expression. This suggests that infants in the upright condition processed facial identity and emotional expression in conjunction with one another.     

Adult Perceptions of Positive and Negative Infant Emotional Expressions

Adults' perceptions provide information about the emotional meaning of infant facial expressions. This study asks whether similar facial movements influence adult perceptions of emotional intensity in both infant positive (smile) and negative (cry face) facial expressions. Ninety‐five college students rated a series of naturally occurring and digitally edited images of infant facial expressions. Naturally occurring smiles and cry faces involving the co‐occurrence of greater lip movement, mouth opening, and eye constriction, were rated as expressing stronger positive and negative emotion, respectively, than expressions without these 3 features. Ratings of digitally edited expressions indicated that eye constriction contributed to higher ratings of positive emotion in smiles (i.e., in Duchenne smiles) and greater eye constriction contributed to higher ratings of negative emotion in cry faces. Stronger mouth opening contributed to higher ratings of arousal in both smiles and cry faces. These findings indicate a set of similar facial movements are linked to perceptions of greater emotional intensity, whether the movements occur in positive or negative infant emotional expressions. This proposal is discussed with reference to discrete, componential, and dynamic systems theories of emotion.     

Attention Capture by Direct Gaze is Robust to Context and Task Demands

Eye-tracking was used to investigate whether gaze direction would influence the visual scanning of faces, when presented in the context of a full character, in different social settings, and with different task demands. Participants viewed individual computer agents against either a blank background or a bar scene setting, during both a free-viewing task and an attractiveness rating task for each character. Faces with a direct gaze were viewed longer than faces with an averted gaze regardless of body context, social settings, and task demands. Additionally, participants evaluated characters with a direct gaze as more attractive than characters with an averted gaze. These results, obtained with pictures of computer agents rather than real people, suggest that direct gaze is a powerful attention grabbing stimulus that is robust to background context or task demands.     

Do Socially Anxious Children Show Deficits in Classifying Facial Expressions of Emotions?

Studies with socially anxious adults suggest that social anxiety is associated with problems in decoding other persons' facial expressions of emotions. Corresponding studies with socially anxious children are lacking. The aim of the present study was to test whether socially phobic children show deficits in classifying facial expressions of emotions or show a response bias for negative facial expressions. Fifty socially anxious and 25 socially non-anxious children (age 8 to 12) participated in the study. Pictures of faces with either neutral, positive (joyful) or negative (angry, disgusted, sad) facial expressions (24 per category) were presented for 60 ms on a monitor screen in random order. The children were asked to indicate by pressing a key whether the facial expression was neutral, positive, or negative, and to rate how confident they were about their classification. With regard to frequency of errors the socially anxious children reported significantly more often that they saw emotions when neutral faces were presented. Moreover, reaction times were longer. However, they did not feel less certain about their performance. There is neither an indication of an enhanced ability to decode negative facial expressions in socially anxious children, nor was there a specific tendency to interpret neutral or positive faces as negative.     

Differential Status Evaluations and Racial Bias in the Chilean Segregated School System

Although there is growing interest in studying the long‐ignored relationship between stratification and race in Chile, racial bias in person perception remains unknown. We hypothesize that the segregation of the Chilean school system generated a prestige order in which pupils are differentiated by status characteristics according to the type of school they attend, and that these evaluations are based on racial traits. To test this hypothesis, we study whether facial appearance is sufficient to impute the type of school a pupil is attending, and whether these categorizations evoke different status evaluations of wealth and morality based on race. Results confirm that participants’ perceptions of facial appearance allow them to situate pupils in the Chilean social structure. Faces categorized as studying at different types of schools varied in their perceived wealth. However, the relationship between moral traits and types of schools was weak. We also found evidence of racial bias in the participants’ perceptions of pupils’ faces: faces categorized as enrolled in municipal schools (low status) were judged with Amerindian or mestizo racial traits, while faces categorized as attending private fee‐paying schools (high status) were judged with white racial traits. We did not find a relationship between race and morality.     

The Emergence and Stability of the Attentional Bias to Fearful Faces in Infancy

Several studies have shown that at 7 months of age, infants display an attentional bias toward fearful facial expressions. In this study, we analyzed visual attention and heart rate data from a cross‐sectional study with 5‐, 7‐, 9‐, and 11‐month‐old infants (Experiment 1) and visual attention from a longitudinal study with 5‐ and 7‐month‐old infants (Experiment 2) to examine the emergence and stability of the attentional bias to fearful facial expressions. In both experiments, the attentional bias to fearful faces appeared to emerge between 5 and 7 months of age: 5‐month‐olds did not show a difference in disengaging attention from fearful and nonfearful faces, whereas 7‐ and 9‐month‐old infants had a lower probability of disengaging attention from fearful than nonfearful faces. Across the age groups, heart rate (HR) data (Experiment 1) showed a more pronounced and longer‐lasting HR deceleration to fearful than nonfearful expressions. The results are discussed in relation to the development of the perception and experience of fear and the interaction between emotional and attentional processes.     

Evidence of the Face Inversion Effect in 4‐Month‐Old Infants

This study tested the presence of the face inversion effect in 4‐month‐old infants using habituation to criterion followed by a novelty preference paradigm. Results of Experiment 1 confirmed previous findings, showing that when 1 single photograph of a face is presented in the habituation phase and when infants are required to recognize the same photograph, no differences in recognition performance with upright and inverted faces are found. However, Experiment 2 showed that, when infants are habituated to a face shown in a variety of poses and are required to recognize a new pose of the same face, infants' recognition performances were higher for upright than for inverted faces. Overall, results indicate that, under some experimental conditions, 4‐month‐olds process faces differently according to whether faces are presented upright or inverted.
