A Review of Attractiveness Preferences in Infancy: From Faces to Objects

Despite some interpersonal variability, judgments of facial attractiveness are largely shared by most individuals, both within and between cultures. Infants are also sensitive to attractive faces even before being influenced by cultural standards of beauty. The intercultural agreement on this matter and its emergence during infancy suggest an evolutionary basis for facial attractiveness. Sensitivity to facial attractiveness is typically understood through evolutionary-based frameworks, either reflecting mate selection mechanisms or emerging as by-products of brain processing and perceptual sensory biases. In the current article, we review data on the emergence and the development of attractiveness preferences in infants, focusing on mechanisms that may explain or contribute to these preferences such as familiarity or fluency in processing. We further discuss the possibility that infants’ preference for attractiveness could extend to other stimuli than faces like objects or visual art. Potential directions for future research are proposed for developmental and comparative approaches.

Preference for Averageness in Faces Does Not Generalize to Non-Human Primates.

Facial attractiveness is a long-standing topic of active study in both neuroscience and social science, motivated by its positive social consequences. Over the past few decades, it has been established that averageness is a major factor influencing judgments of facial attractiveness in humans. Non-human primates share similar social behaviors as well as neural mechanisms related to face processing with humans. However, it is unknown whether monkeys, like humans, also find particular faces attractive and, if so, which kind of facial traits they prefer. To address these questions, we investigated the effect of averageness on preferences for faces in monkeys. We tested three adult male rhesus macaques using a visual paired comparison (VPC) task, in which they viewed pairs of faces (both individual faces, or one individual face and one average face); viewing time was used as a measure of preference. We did find that monkeys looked longer at certain individual faces than others. However, unlike humans, monkeys did not prefer the average face over individual faces. In fact, the more the individual face differed from the average face, the longer the monkeys looked at it, indicating that the average face likely plays a role in face recognition rather than in judgments of facial attractiveness: in models of face recognition, the average face operates as the norm against which individual faces are compared and recognized. Taken together, our study suggests that the preference for averageness in faces does not generalize to non-human primates.

Investorss Reactions to Earnings Surprises When Management Issues Goal versus Expectation Earnings Guidance

We investigate whether nonprofessional investors’ responses to a company’s reported earnings differ when management earnings guidance is presented as a goal or an expectation. We present 64 MBA students and 262 Mturk participants with management earnings guidance, manipulating between-subjects whether management provides the guidance in the form of a “goal” or an “expectation” and whether the company’s reported earnings fall short or exceed investors’ expectations that are derived from management’s earnings guidance. Our experimental results suggest that investors respond less negatively when reported earnings fall short of investors’ expectations, but not less positively when earnings exceed investors’ expectations, when earnings guidance is issued as a goal rather than as an expectation. Mediation analysis of post-experiment questions supports the interpretation that earnings falling short of investors’ expectations leads investors to perceive managers as less competent and be more disappointed when managers issue expectation guidance rather than goal guidance, which in turn influences investors’ attractiveness judgments of the company.

Own Attractiveness and Dissatisfaction With Physical Appearance Independently Predict the Salience of Facial Cues to Size When Women Judge Other Women's Attractiveness.

While facial cues to body size are a valid guide to health and attractiveness, it is unclear whether the observer's own condition predicts the salience of (low) size as a cue to female attractiveness. The current study examines whether measures related to women's own attractiveness/appearance predict the extent to which they use facial cues to size to differentiate other women on the attractiveness dimension. Women completed a body mass index (BMI) preference task, where they indicated their preference for high- versus low-BMI versions of the same woman, provided data to calculate their BMI and completed various psychometric measures (self-rated attractiveness/health, dissatisfaction with physical appearance). Here, attractive women and women who were dissatisfied with their own appearance were more likely to associate facial cues to low body size with high attractiveness. These data suggest that psychological factors related to women's appearance shape their evaluations of other women based on cues to size. Such variation in attractiveness judgements may function to reduce the costs of female competition for resources, for example, by identifying "quality" rivals or excluding others based on cues to size.

Small but attractive: Dimensions of new venture employer attractiveness and the moderating role of applicants' entrepreneurial behaviors

Operating under high levels of uncertainty and limited public recognition, one of the most significant challenges for new ventures is attracting qualified employees. Building on the concept of legitimate distinctiveness, our study investigates how recruitment-related heterogeneous and homogeneous entrepreneurial identity claims influence applicants' judgments of new ventures' employer attractiveness. We combine anticipatory psychological contract theory and legitimacy theory to build theory about the way applicants evaluate new venture employer attractiveness. Using a metric conjoint experiment, we study 9,824 employer attractiveness judgments made by 307 job seekers. Our multi-level approach also yields cross-level interaction effects of job applicants' innovative behavior, which offer novel insights into which new venture employment dimensions specifically attract entrepreneurially-minded potential employees. We derive implications for new venture recruitment theory and offer practical implications for startup staffing.

Human colour in mate choice and competition.

The colour of our skin and clothing affects how others perceive us and how we behave. Human skin colour varies conspicuously with genetic ancestry, but even subtle changes in skin colour due to diet, blood oxygenation and hormone levels influence social perceptions. In this review, we describe the theoretical and empirical frameworks in which human colour is researched. We explore how subtle skin colour differences relate to judgements of health and attractiveness. Also, because humans are one of the few organisms able to manipulate their apparent colour, we review how cosmetics and clothing are implicated in courtship and competition, both inside the laboratory and in the real world. Research on human colour is in its infancy compared with human psychophysics and colour research in non-human animals, and hence we present best-practice guidelines for methods and reporting, which we hope will improve the validity and reproducibility of studies on human coloration.This article is part of the themed issue 'Animal coloration: production, perception, function and application'.

Attractiveness Is Multimodal: Beauty Is Also in the Nose and Ear of the Beholder.

Attractiveness plays a central role in human non-verbal communication and has been broadly examined in diverse subfields of contemporary psychology. Researchers have garnered compelling evidence in support of the evolutionary functions of physical attractiveness and its role in our daily lives, while at the same time, having largely ignored the significant contribution of non-visual modalities and the relationships among them. Acoustic and olfactory cues can, separately or in combination, strongly influence the perceived attractiveness of an individual and therefore attitudes and actions toward that person. Here, we discuss the relative importance of visual, auditory and olfactory traits in judgments of attractiveness, and review neural and behavioral studies that support the highly complex and multimodal nature of person perception. Further, we discuss three alternative evolutionary hypotheses aimed at explaining the function of multiple indices of attractiveness. In this review, we provide several lines of evidence supporting the importance of the voice, body odor, and facial and body appearance in the perception of attractiveness and mate preferences, and therefore the critical need to incorporate cross-modal perception and multisensory integration into future research on human physical attractiveness.

The role of social comparison in social judgments of dental appearance: An experimental study

ObjectiveThe objective of this study was to examine the influence of social comparison on social judgments of dental malalignment in a sample of females. MethodIn a Repeated measures design, N=218 female participants of which N=128 were orthodontic patients (mean age 31.4) and N=90 controls (mean age 26.1) rated their satisfaction with their facial appearance after viewing stereotypically beautiful images of faces (experimental condition) or houses (neutral condition). After 4–6 weeks participants returned to view an image of a female with severe crowding and were asked to make judgments of social competence (SC), intellectual ability (IA), psychological adjustment (PA) and attractiveness (A). ResultsThe comparison of social judgments between high comparers (High SocComp) and low comparers (Low SocComp) was not statistically significant; (SC (t (204)=0.30, p=0.76), IA (t (204)=0.14, p=0.89) PA (t (204)=0.004, p=0.996), A (t(204)=1.26, (p=0.209). However, dentally induced social judgments (DISJ) was statistically significant in the clinical sample than the non-clinical sample SC (t (204)=0.784, p=0.434), IA (t (204)=0.2.15, p=0.033) PA (t (204)=−0.003, p=0.997) A (t (204)=1.58, p=0.116). ConclusionSocial comparison has little impact on DISJ. However, there are differences in DISJs between individuals who seek treatment for their malocclusion versus the nonclinical population; the reason for this is unclear but does not appear to be the result of adoption of societal standards of beauty and instead suggests individual ranking of important ‘beauty areas’ may play a role. Clinical significance statementThis paper uses social comparison theory to investigate the basis of judgments in regards to dental appearance. The findings of this research may help to identify individuals who are more susceptible to societal pressures towards non-ideal dentitions. This will help clinicians become more aware of the patient’s comparison orientation, which seems to have an impact on satisfaction with treatment outcomes. This study may form the foundation for future behaviour studies seeking to alleviate the negative effects of social comparison.

Cue-based estimates of reproductive value explain women's body attractiveness

Abstract Women's body attractiveness is influenced by specific anthropometric cues, including body mass index (BMI), waist-to-hip ratio (WHR), waist-to-stature ratio (WSR), and shoulder-to-waist ratio (SWR). Despite the existence of multiple functional hypotheses to explain these preferences, it remains unclear which cue-based inferences are most influential in regulating evaluations of women's body attractiveness. We argue that (i) the common link to the morphological cues that influence women's body attractiveness is that they all reliably indicate high reproductive value (as defined by youth and low parity); and (ii) ancestrally, selection pressures related to tracking between-women differences in reproductive value would have been among the strongest acting on adaptations for body evaluation. An empirical study then tested the resulting prediction that cue-based estimates of reproductive value function as powerful regulators of women's body attractiveness judgments. Subjects viewed standardized photos of women in swimsuits (with heads obscured), and were assigned to either estimate components of their reproductive value (age or number of offspring) or rate their attractiveness. Structural equation modeling revealed that a latent variable capturing estimated reproductive value was almost perfectly correlated with a latent variable capturing body attractiveness. Moreover, unique associations of women's BMI, WHR, and WSR with their body attractiveness were entirely mediated via estimated reproductive value. These findings provide strong support for the longstanding hypothesis that women's body attractiveness is primarily explained by cue-based estimates of reproductive value – expected future utility as a vehicle of offspring production.

Putative sex-specific human pheromones do not affect gender perception, attractiveness ratings or unfaithfulness judgements of opposite sex faces.

Debate continues over the existence of human sex pheromones. Two substances, androstadienone (AND) and estratetraenol (EST), were recently reported to signal male and female gender, respectively, potentially qualifying them as human sex pheromones. If AND and EST truly signal gender, then they should affect reproductively relevant behaviours such as mate perception. To test this hypothesis, heterosexual, Caucasian human participants completed two computer-based tasks twice, on two consecutive days, exposed to a control scent on one day and a putative pheromone (AND or EST) on the other. In the first task, 46 participants (24 male, 22 female) indicated the gender (male or female) of five gender-neutral facial morphs. Exposure to AND or EST had no effect on gender perception. In the second task, 94 participants (43 male, 51 female) rated photographs of opposite-sex faces for attractiveness and probable sexual unfaithfulness. Exposure to the putative pheromones had no effect on either attractiveness or unfaithfulness ratings. These results are consistent with those of other experimental studies and reviews that suggest AND and EST are unlikely to be human pheromones. The double-blind nature of the current study lends increased support to this conclusion. If human sex pheromones affect our judgements of gender, attractiveness or unfaithfulness from faces, they are unlikely to be AND or EST.

In God we trust? Neural measures reveal lower social conformity among non-religious individuals.

Even in predominantly religious societies, there are substantial individual differences in religious commitment. Why is this? One possibility is that differences in social conformity (i.e. the tendency to think and behave as others do) underlie inclination towards religiosity. However, the link between religiosity and conformity has not yet been directly examined. In this study, we tested the notion that non-religious individuals show dampened social conformity, using both self-reported and neural (EEG-based ERPs) measures of sensitivity to others’ influence. Non-religious vs religious undergraduate subjects completed an experimental task that assessed levels of conformity in a domain unrelated to religion (i.e. in judgments of facial attractiveness). Findings showed that, although both groups yielded to conformity pressures at the self-report level, non-religious individuals did not yield to such pressures in their neural responses. These findings highlight a novel link between religiosity and social conformity, and hold implications for prominent theories about the psychological functions of religion.

Aesthetic Pleasure versus Aesthetic Interest: The Two Routes to Aesthetic Liking.

Although existing research has established that aesthetic pleasure and aesthetic interest are two distinct positive aesthetic responses, empirical research on aesthetic preferences usually considers only aesthetic liking to capture participants’ aesthetic response. This causes some fundamental contradictions in the literature; some studies find a positive relationship between easy-to-process stimulus characteristics and aesthetic liking, while others suggest a negative relationship. The present research addresses these empirical contradictions by investigating the dual character of aesthetic liking as manifested in both the pleasure and interest components. Based on the Pleasure-Interest Model of Aesthetic Liking (PIA Model; Graf and Landwehr, 2015), two studies investigated the formation of pleasure and interest and their relationship with aesthetic liking responses. Using abstract art as the stimuli, Study 1 employed a 3 (stimulus fluency: low, medium, high) × 2 (processing style: automatic, controlled) × 2 (aesthetic response: pleasure, interest) experimental design to examine the processing dynamics responsible for experiencing aesthetic pleasure versus aesthetic interest. We find that the effect of stimulus fluency on pleasure is mediated by a gut-level fluency experience. Stimulus fluency and interest, by contrast, are related through a process of disfluency reduction, such that disfluent stimuli that grow more fluent due to processing efforts become interesting. The second study employed product designs (bikes, chairs, and lamps) as stimuli and a 2 (fluency: low, high) × 2 (processing style: automatic, controlled) × 3 (product type: bike, chair, lamp) experimental design to examine pleasure and interest as mediators of the relationship between stimulus fluency and design attractiveness. With respect to lamps and chairs, the results suggest that the effect of stimulus fluency on attractiveness is fully mediated by aesthetic pleasure, especially in the automatic processing style. Conversely, disfluent product designs can enhance design attractiveness judgments due to interest when a controlled processing style is adopted.

Are there vocal cues to human developmental stability? Relationships between facial fluctuating asymmetry and voice attractiveness

Fluctuating asymmetry (FA), deviation from perfect bilateral symmetry, is thought to reflect an organism's relative inability to maintain stable morphological development in the face of environmental and genetic stressors. Previous research has documented negative relationships between FA and attractiveness judgments in humans, but scant research has explored relationships between the human voice and this putative marker of genetic quality in either sex. Only one study (and in women only) has explored relationships between vocal attractiveness and asymmetry of the face, a feature-rich trait space central in prior work on human genetic quality and mate choice. We therefore examined this relationship in three studies comprising 231 men and 240 women from two Western samples as well as Hadza hunter–gatherers of Tanzania. Voice recordings were collected and rated for attractiveness, and FA was computed from two-dimensional facial images as well as, for a subset of men, three-dimensional facial scans. Through meta-analysis of our results and those of prior studies, we found a negative association between FA and vocal attractiveness that was highly robust and statistically significant whether we included effect sizes from previously published work, or only those from the present research, and regardless of the inclusion of any individual sample or method of assessing FA (e.g., facial or limb FA). Weighted mean correlations between FA and vocal attractiveness across studies were −.23 for men and −.29 for women. This research thus offers strong support for the hypothesis that voices provide cues to genetic quality in humans.

Physical attraction to reliable, low variability nervous systems: Reaction time variability predicts attractiveness

The human face cues a range of important fitness information, which guides mate selection towards desirable others. Given humans’ high investment in the central nervous system (CNS), cues to CNS function should be especially important in social selection. We tested if facial attractiveness preferences are sensitive to the reliability of human nervous system function. Several decades of research suggest an operational measure for CNS reliability is reaction time variability, which is measured by standard deviation of reaction times across trials. Across two experiments, we show that low reaction time variability is associated with facial attractiveness. Moreover, variability in performance made a unique contribution to attractiveness judgements above and beyond both physical health and sex-typicality judgements, which have previously been associated with perceptions of attractiveness. In a third experiment, we empirically estimated the distribution of attractiveness preferences expected by chance and show that the size and direction of our results in Experiments 1 and 2 are statistically unlikely without reference to reaction time variability. We conclude that an operating characteristic of the human nervous system, reliability of information processing, is signalled to others through facial appearance.

Can we believe judgements of human physical attractiveness?

A key question in attractiveness studies is the validity of the reported results outside the narrow confines of the experimental paradigm used. Does the range of physical features in a set of pictures used to test attractiveness judgements predict the individual ratings of each body? Or does each stimulus have an attractiveness value independent of the range of attractiveness found in the image set of which it is a part? An additional problem is that because participants are often shown a relatively large array of images in a short space of time, this may produce perceptual biases, which could cause a short-term shift in attractiveness preferences, which are not usually found in real-life mate choice decisions. To address this issue, we asked 20 participants (10 male and 10 female) to judge the attractiveness of 20 digital photographs of female bodies. We then asked a different set of 400 people (who had not seen the body pictures) to judge the attractiveness of one of the bodies from the set (so each body was rated in isolation by 10 male and 10 female participants). We then compared the attractiveness judgement each body received when seen independently versus when it was seen within the context of a set of bodies. The results showed no significant difference between the two conditions, which suggests that each body has an attractiveness value independent of the attractiveness of the other bodies with which it is viewed.

The Relative Importance of Sexual Dimorphism, Fluctuating Asymmetry, and Color Cues to Health during Evaluation of Potential Partners’ Facial Photographs

Sexual dimorphism, symmetry, and coloration in human faces putatively signal information relevant to mate selection and reproduction. Although the independent contributions of these characteristics to judgments of attractiveness are well established, relatively few studies have examined whether individuals prioritize certain features over others. Here, participants (N=542, 315 female) ranked six sets of facial photographs (3 male, 3 female) by their preference for starting long- and short-term romantic relationships with each person depicted. Composite-based digital transformations were applied such that each image set contained 11 different versions of the same identity. Each photograph in each image set had a unique combination of three traits: sexual dimorphism, symmetry, and color cues to health. Using conjoint analysis to evaluate participants' ranking decisions, we found that participants prioritized cues to sexual dimorphism over symmetry and color cues to health. Sexual dimorphism was also found to be relatively more important for the evaluation of male faces than for female faces, whereas symmetry and color cues to health were relatively more important for the evaluation of female faces than for male faces. Symmetry and color cues to health were more important for long-term versus short-term evaluations for female faces, but not male faces. Analyses of utility estimates reveal that our data are consistent with research showing that preferences for facial masculinity and femininity in male and female faces vary according to relationship context. These findings are interpreted in the context of previous work examining the influence of these facial attributes on romantic partner perception.

The role of consonants in the perception of vocal attractiveness

Research on vocal attractiveness has identified several acoustic cues intrinsic to vowels (e.g., pitch) that affect judgements of attractiveness and have shown listeners generally agree in their ratings (e.g., Babel, McGuire, & King 2014). Research in this area has, however, been largely limited to an examination of vowels. The current study builds on past work by examining an array of acoustic cues intrinsic to consonants to ascertain how they affect judgements of vocal attractiveness. Two native speakers of Canadian English were recorded saying one-syllable words of the form sCVC or p/t/kVC. The acoustic cues of center of gravity and duration of /s/ and voice onset time of /p/, /t/, and /k/ were manipulated to both increase and decrease the value of each cue. Vowel pitch was also included in the analysis as a baseline for comparison with past research. Participants listened to the original and manipulated tokens and were asked to judge vocal attractiveness using a 7-point Likert scale. The data of 32 people (female, N = 16) aged 19-32 were analyzed, using mixed effects models. The most interesting finding of the current study was that while not all acoustic cues of consonants played a role in perceptions of vocal attractiveness, /s/ duration did, and for this cue both the speaker and listener sex were important to how the cue was perceived. This suggests that not only are male and female voices judged by different standards as to what is attractive, but that men and women are using different criteria when making these judgements.

Origins of ‘the eye of the beholder’: Individual differences in face attractiveness judgments are shaped primarily by environments

Orienting a logo upward or downward may seem like an arbitrary graphic design decision, but we propose that it can have important implications for consumer judgments. In particular, we find across four experimental studies and a content analysis that diagonal direction can convey different levels of activity with upward—or ascending—diagonals conveying greater activity and effort than downward—or descending—diagonals. Consequently, when the context highlights the benefits of activity (vs. passivity), upward (vs. downward) diagonals lead to more favorable product judgments, greater product efficacy beliefs, and greater post-consumption satisfaction. Furthermore, we provide process evidence that perceived product efficacy beliefs mediate these effects, and that the effect is strongest when the object being visually oriented is text rather than images. These findings are particularly important in light of our content analysis findings that diagonal orientation is a relatively underutilized design feature. Collectively, our findings suggest that firms should use upward diagonals when the product context highlights a favorable view of activity. Otherwise, the firm should use downward diagonals, especially when the product context encourages consumers to view passivity favorably.

The Influence of Averageness on Adults' Perceptions of Attractiveness: The Effect of Early Visual Deprivation.

Adults who missed early visual input because of congenital cataracts later have deficits in many aspects of face processing. Here we investigated whether they make normal judgments of facial attractiveness. In particular, we studied whether their perceptions are affected normally by a face's proximity to the population mean, as is true of typically developing adults, who find average faces to be more attractive than most other faces. We compared the judgments of facial attractiveness of 12 cataract-reversal patients to norms established from 36 adults with normal vision. Participants viewed pairs of adult male and adult female faces that had been transformed 50% toward and 50% away from their respective group averages, and selected which face was more attractive. Averageness influenced patients' judgments of attractiveness, but to a lesser extent than controls. The results suggest that cataract-reversal patients are able to develop a system for representing faces with a privileged position for an average face, consistent with evidence from identity aftereffects. However, early visual experience is necessary to set up the neural architecture necessary for averageness to influence perceptions of attractiveness with its normal potency.
