Context effects on the perceived physical attractiveness of faces

Four experiments were conducted to study the nature of context effects on the perceived physical attractiveness of faces. In Experiment 1, photos of faces scaled on attractiveness were presented in sets of three, with target faces appearing in the middle flanked by two context faces. The target faces were of average attractiveness, with the context faces being either high, average, or low in attractiveness. The effect of the context was one of assimilation, rather than contrast, regardless of whether the persons in the photos were portrayed to be associated. This result was interpreted in terms of a “generalized halo effect” for judgments of the physical attractiveness of stimuli within a group. Presenting the persons of a set as friends enhanced the perceived attractiveness of the target face but only when the context did not contain a face of low attractiveness. In Experiment 2, the assimilation effect was observed to carry over to influence ratings of the target faces several minutes after the context faces had been removed. Experiment 3 showed the assimilation effect to be robust regardless of whether the context was composed of two faces or one, but Experiment 4 showed the assimilation effect to be evident only when the context faces were presented simultaneously with the target.     

Analyses of facial attractiveness on feminised and juvenilised faces

We conducted two experiments to investigate the psychological factors affecting the attractiveness of composite faces. Feminised or juvenilised Japanese faces were created by morphing between average male and female adult faces or between average male (female) adult and boy (girl) faces. In experiment 1, we asked the participants to rank the attractiveness of these faces. The results showed moderately juvenilised faces to be highly attractive. In experiment 2, we analysed the impressions the participants had of the composite faces by the semantic-differential method and determined the factors that largely affected attractiveness. On the basis of the factor scores, we plotted the faces in factor spaces and analysed the locations of attractive faces. We found that most of the attractive juvenilised faces involved impressions corresponding to an augmentation of femininity, characterised by the factors of 'elegance', 'mildness', and 'youthfulness', which the attractive faces potentially had.     

The attractiveness of nonface averages: implications for an evolutionary explanation of the attractiveness of average faces

Researchers have argued that humans' attraction to average faces reflects an evolved psychological mechanism to identify high-quality mates. If this direct-selection account is correct, there is no reason to expect a similar averageness bias for stimuli that are irrelevant to reproductive fitness. The current study, however, found a strong relationship between averageness and attractiveness for dogs, wristwatches, and birds. The most parsimonious explanation is that humans have a general attraction to prototypical exemplars, and that their attraction to average faces is a reflection of this more general attraction. We tested whether a general preference for familiar stimuli can account for the attractiveness of averageness. This account was not supported for dogs or birds, but could not be ruled out for watches.     

Variation in perceived attractiveness: differences between dynamic and static faces

Studies that attempt to define facial attractiveness often do so in terms of structural features of the face (e.g., symmetry, averageness). However, these studies typically use static images of faces that may not be analogous to dynamic faces that are frequently used in other areas of attractiveness research, such as research investigating the impact of attractiveness on social interaction. The current studies investigated similarities and differences in how dynamic and static faces are perceived and evaluated. Study 1 demonstrated that dynamic and static faces are judged by different evaluative standards. Study 2 demonstrated that perceived emotion may be more salient in judging the attractiveness of dynamic faces than in judging the attractiveness of static faces. These findings illustrate the need to more fully explore the differences between dynamic and static faces to facilitate a better understanding of the characteristics underlying perceived attractiveness.     

Redness enhances perceived aggression, dominance and attractiveness in men's faces

In a range of non-human primate, bird and fish species, the intensity of red coloration in males is associated with social dominance, testosterone levels and mate selection. In humans too, skin redness is associated with health, but it is not known whether - as in non-human species - it is also associated with dominance and links to attractiveness have not been thoroughly investigated. Here we allow female participants to manipulate the CIELab a* value (red-green axis) of skin to maximize the perceived aggression, dominance and attractiveness of photographs of men's faces, and make two findings. First, participants increased a* (increasing redness) to enhance each attribute, suggesting that facial redness is perceived as conveying similar information about a male's qualities in humans as it does in non-human species. Second, there were significant differences between trial types: the highest levels of red were associated with aggression, an intermediate level with dominance, and the least with attractiveness. These differences may reflect a trade-off between the benefits of selecting a healthy, dominant partner and the negative consequences of aggression.     

Familiarity breeds attraction: effects of exposure on the attractiveness of typical and distinctive faces

Several studies have shown that facial attractiveness is positively correlated with both familiarity and typicality. Here we manipulated the familiarity of typical and distinctive faces to measure the effect on attractiveness. In our first experiment, we collected ratings of attractiveness, distinctiveness, and familiarity using three different groups of participants. Our stimuli included 84 images of female faces, presented in a full-face view. We replicated the finding that attractiveness ratings negatively correlate with distinctiveness ratings. In addition, we showed that attractiveness ratings were positively correlated with familiarity ratings. In our second experiment, we demonstrated that increasing exposure to faces increases their attractiveness, although there was no differential effect of exposure on typical and distinctive faces. Our results suggest that episodic familiarity affects attractiveness ratings independently of general or structural familiarity. The implications of our findings for the 'face-space' model are discussed.     

Lip colour affects perceived sex typicality and attractiveness of human faces

The luminance contrast between facial features and facial skin is greater in women than in men, and women's use of make-up enhances this contrast. In black-and-white photographs, increased luminance contrast enhances femininity and attractiveness in women's faces, but reduces masculinity and attractiveness in men's faces. In Caucasians, much of the contrast between the lips and facial skin is in redness. Red lips have been considered attractive in women in geographically and temporally diverse cultures, possibly because they mimic vasodilation associated with sexual arousal. Here, we investigate the effects of lip luminance and colour contrast on the attractiveness and sex typicality (masculinity/femininity) of human faces. In a Caucasian sample, we allowed participants to manipulate the colour of the lips in colour-calibrated face photographs along CIELab L* (light--dark), a* (red--green), and b* (yellow--blue) axes to enhance apparent attractiveness and sex typicality. Participants increased redness contrast to enhance femininity and attractiveness of female faces, but reduced redness contrast to enhance masculinity of men's faces. Lip blueness was reduced more in female than male faces. Increased lightness contrast enhanced the attractiveness of both sexes, and had little effect on perceptions of sex typicality. The association between lip colour contrast and attractiveness in women's faces may be attributable to its association with oxygenated blood perfusion indicating oestrogen levels, sexual arousal, and cardiac and respiratory health.     

The role of facial attractiveness and facial masculinity/femininity in sex classification of faces

We tested whether adults (experiment 1) and 4 - 5-year-old children (experiment 2) identify the sex of highly attractive faces faster and more accurately than not very attractive faces in a reaction-time task. We also assessed whether facial masculinity/femininity facilitated identification of sex. Results showed that attractiveness facilitated adults' sex classification of both female and male faces and children's sex classification of female, but not male, faces. Moreover, attractiveness affected the speed and accuracy of sex classification independently of masculinity/femininity. High masculinity in male faces, but not high femininity in female faces, also facilitated sex classification for both adults and children. These findings provide important new data on how the facial cues of attractiveness and masculinity/femininity contribute to the task of sex classification and provide evidence for developmental differences in how adults and children use these cues. Additionally, these findings provide support for Langlois and Roggman's (1990 Psychological Science 1 115 121) averageness theory of attractiveness.     

Temporal shifts in eye gaze and facial expressions independently contribute to the perceived attractiveness of unfamiliar faces

ABSTRACT

We investigated whether attractiveness ratings of expressive faces would be affected by gaze shifts towards or away from the observer. In all experiments, effects of facial expression were found, with higher attractiveness ratings to positive over negative expressions, irrespective of effects of gaze-shifts. In the first experiment faces with gaze shifts away from the observer were preferred. However, when the dynamics of the gaze shift was disrupted, by adding an intermediate delay, the effect of direction of gaze shift disappeared. By manipulating the relative duration of each gaze direction during a gaze shift we found higher attractiveness ratings to faces with a longer duration of direct gaze, particularly in the initial exposure to a face. Our findings suggest that although the temporal dynamics of eye gaze and facial expressions influence the aesthetic evaluation of faces, these cues appear to act independently rather than in an integrated manner for social perception.     

Internet research: Self-monitoring and judgments of attractiveness

Two studies examined the relationship between self-monitoring and factors influencing romantic attraction to others. In Study 1, participants completed an Internet-mediated version of the Self-Monitoring Scale (Gangestad & Snyder, 1985) and indicated which of two people (one physically attractive, one with a more desirable personality) they found most attractive. Results matched previous findings (Snyder, Berscheid, & Glick, 1985), but the effect was smaller. Study 2, a paper-and-pencil replication of Study 1, examined whether the weaker effect was due to Internet mediation and found no differences in the choices made by high and low self-monitors. Results suggested that while determinants of attraction may vary for different populations, Internet research methods can tap the same phenomena as traditional laboratory studies.     

The perception of attractiveness and trustworthiness in male faces affects hypothetical voting decisions differently in wartime and peacetime scenarios

Facial appearance of candidates has been linked to real election outcomes. Here we extend these findings by examining the contributions of attractiveness and trustworthiness in male faces to perceived votability. We first use real faces to show that attractiveness and trustworthiness are positively and independently related to perceptions of good leadership (rating study). We then show that computer graphic manipulations of attractiveness and trustworthiness influence choice of leader (Experiments 1 and 2). Finally, we show that changing context from wartime to peacetime can affect which face receives the most votes. Attractive faces were relatively more valued for wartime and trustworthy faces relatively more valued for peacetime (Experiments 1 and 2). This pattern suggests that attractiveness, which may indicate health and fitness, is perceived to be a useful attribute in wartime leaders, whereas trustworthiness, which may indicate prosocial traits, is perceived to be more important during peacetime. Our studies highlight the possible role of facial appearance in voting behaviour and the role of attributions of attractiveness and trust. We also show that there may be no general characteristics of faces that make them perceived as the best choice of leader; leaders may be chosen because of characteristics that are perceived as the best for leaders to possess in particular situations.

Beer goggles: blood alcohol concentration in relation to attractiveness ratings for unfamiliar opposite sex faces in naturalistic settings

The popular notion that alcohol intoxication enhances perceptions of the physical attractiveness of the opposite sex has been inconsistently supported. The current study tested intoxicated and non-intoxicated persons of both genders in naturalistic settings after measuring their blood alcohol concentration (BAC) by a breath test. A sample of 80 heterosexual university student social drinkers was recruited at a campus pub and campus parties over a 3-month period to take a survey rating the attractiveness of unfamiliar faces of the opposite gender presented in photographs. Attractiveness ratings were positively correlated with BAC. Analysis of covariance (ANCOVA) was conducted on attractiveness ratings with independent variables of gender and BAC group, with three levels of the latter: non-intoxicated (BAC = 0), moderately intoxicated (BAC .01% - .09%), and highly intoxicated (BAC .10% - .19%). Both intoxicated groups gave significantly higher attractiveness ratings than non-intoxicated controls. The findings confirm the "beer goggles" phenomenon of folk psychology for both genders, although the mechanism remains unclear.

The influence of facial attractiveness on imitation

People judge, evaluate, and treat attractive people better than moderately attractive or unattractive people [Langlois, J. H., Kalakanis, L., Rubenstein, A. J., Larson, A., Hallam, M., & Smoot, M. (2000). Maxims or myths of beauty? A meta-analytic and theoretical review. Psychological Bulletin, 126, 390–423]. The fact that individuals like attractive people combined with the finding that individuals imitate the ones they like, suggests that they may be more prone to imitate attractive people. The present research extends previous work on attractiveness and imitation by examining this hypothesis. Using a novel coloring procedure, we show that attractive females are imitated more than unattractive females (Experiment 1) and that attractive males are imitated more than unattractive males (Experiment 2). Importantly, this imitation occurs without any direct or anticipated contact with the target individual and without awareness of the influence of attractiveness on imitation behavior.     

Effects of the beholder's age on the perception of facial attractiveness

Children have been shown to prefer faces rated as highly attractive by adults over faces rated as quite unattractive. We investigated to what extent this agreement holds not only for the general direction of preferences but for preference strengths as well. In a choice experiment, we presented 40 nine-year-old girls and their mothers and 40 twelve-year-old girls and their mothers with pairs of women's and girls' faces and asked the subjects to pick the face that appeared prettier to them. Preference frequencies and simple attractiveness scales derived from these preference frequencies by fitting the Bradley-Terry-Luce rule (Luce, D. R. (1959). Individual choice behavior: a theoretical analysis. New York: Wiley) were compared across subject groups. For the women's faces, we found no difference in preferences between nine-year-olds, twelve-year-olds, and adults, neither in direction nor in strength. For the girls' faces, we also found no major differences in preference direction, however, we did find reliable differences in preference strengths. To a considerable part these differences were due to the fact that the children showed less pronounced preferences between face stimuli than the adults. These results suggest a role of developmental factors in the perception of facial attractiveness.     

Angry faces are more resistant to forgetting than are happy faces: directed forgetting effects on the identity of emotional faces

Using the item-method directed forgetting paradigm (i.e. intentionally forgetting specified information), we examined directed forgetting of facial identity as a function of facial expression and the sex of the expresser and perceiver. Participants were presented with happy and angry male and female faces cued for either forgetting or remembering, and were then asked to recognise previously studied faces from among a series of neutral faces. For each recognised test face, participants also recalled the face’s previously displayed emotional expression. We found that angry faces were more resistant to forgetting than were happy faces. Furthermore, angry expressions on male faces and happy expressions on female faces were recognised and recalled better than vice versa. Signal detection analyses revealed that male faces gave rise to a greater sensitivity than female faces did, and male participants, but not female participants, showed greater sensitivity to male faces than to female faces. Several theoretical implications are discussed.     

The effect of frustrative nonreward on the attractiveness of the omitted reward

Two experiments were performed to test the hypothesis that omission of a previously received reward is followed by greater motivation to obtain that specific reward, as compared with the case where the reward had been present. In Experiment 1, experimental rats regularly received food rewards (R_a) at one goal, followed by a choice between food and milk (R_b). Control animals received the same choice without food preceding it. Reward magnitudes were manipulated so as to produce a preference for R_b, and additional forced trials were given each day to equalise experience of the two rewards. In the test phase both groups received trials with R_a present (R) or absent (N) at the first goal. The experimental Ss shifted their choice towards R_a on N trials; the controls did not behave differently after R and N. Experiment 2 was similar, except that R_a was milk and R_b food. The same effect of N on experimental animals was obtained. It is argued that the results are relevant to the double-runway ‘frustration effect’, and cannot be explained by existing theories of frustration.     

Limitations on Embedding in Coordinate Structures

Coordinate structures have traditionally been analyzed as having no internal structure other than the sequencing of their members. In particular, the possibility that the members of coordinate structures may themselves be coordinate structures has not been widely recognized. Those who have recognized the possibility of such embedding of coordinate structures have assumed that there are no limits on the depth of such embedding, just as there are no limits on the depth of embedding in subordinate structures. However, coordinate-structure embedding in English occurs only in order to prevent coordinate structures from containing distinct connectives (e.g., and and or), distinct junctures (breaks) between members, and sequences of members in which the first is introduced by a connective while the second is not. In order to prevent these conditions from arising, the depth of coordinate-structure embedding does not have to exceed 2. This limitation on coordinate-structure embedding must be dealt with by the grammars of natural languages; it is not simply a performance limitation. Standard generative mechanisms (finite-state, phrase-structure, and transformational grammars, including recently proposed analyses of coordinate structures based on the minimalist program) do not provide an adequate account of this limitation. On the other hand, a theory of constraint satisfaction such as optimality theory, in which ranked constraints select the optimally structured outputs for given inputs made up of members, connectives, and junctures, does do so. A detailed optimality theoretic analysis of coordinate structures in English is proposed which accounts for the limitation on coordinate-structure embedding, as well as several other properties of those structures, and of their interactions with subordinate constructions.
