Beauty and the Mask

The effects of image resolution and exposure duration on facial beauty and ugliness evaluations

The beauty or ugliness of a face is affected by factors such as the resolution of the face image presented on the screen and its exposure duration. The present study investigated the effects of image resolution and exposure duration on the beauty and ugliness evaluations of face images processed with down-sampling and Gaussian blurring. We prepared two types of face images with these blur processing treatments and conducted two experiments to evaluate beauty and ugliness perceptions at various exposure durations. The data were analyzed using linear mixed models. We found that in both cases of blurring, the more the blurring, the lower the facial beauty and the higher the ugliness perceived. We also found that the shorter the exposure duration, the higher the facial beauty and the lower the ugliness perceived. These results suggest that a positive bias is likely to occur when sufficient temporal information is unavailable, while a negative bias is more likely when image information is insufficient and there is a limited exposure duration. This highlights the importance of both exposure duration and visual clarity in shaping evaluations of facial beauty and ugliness.

Visual Attention toward Patients with Hemifacial Microsomia Reconstruction: A Prospective Eye-Tracking Study

BACKGROUND

Facial areas attracting the most visual attention in hemifacial microsomia (HFM) are poorly understood. Furthermore, it is not clear whether and how visual attention changes from before surgery to after surgery. This study characterized layperson visual attention to before and after reconstruction HFM using eye-tracking technology.

METHODS

Visual fixations (Tobii Pro Nano) were recorded in 4 areas of interest from 60 participants completing 2 consecutive trials of 68 total images in each hemiface of 17 patients with HFM before and after orthognathic jaw reconstruction. Linear mixed effect models evaluated whether visual fixations were affected by surgical reconstruction.

RESULTS A TOTAL OF

47,354 visual fixations were captured over 120 trials within defined areas of interest. Linear mixed effect models revealed significantly decreased postoperative visual fixations in the mandible and chin region [before reconstruction, 716 (54.8%); after reconstruction, 591 (45.2%); β = -0.198, SE = 0.056, z = -3.550, P < 0.001). Analysis also revealed significantly increased postoperative visual fixations in the forehead and orbit region (before reconstruction, 11,350 [48.6%]; after reconstruction, 12,000 [51.4%]; β = 0.086, SE = 0.015, z = 5.664, P < 0.00001).

CONCLUSIONS

Following corrective jaw surgery for HFM, laypersons demonstrated significantly less visual attention to the mandible and chin and increased visual attention to the forehead and orbit. These findings suggest that postoperative improvement toward aesthetic normalcy may reduce visual attention to previously anomalous anatomy.

The Crucial Role of the Eyes in Predicting Facial Attractiveness from Parts

Perceiving facial attractiveness based on partial information is a common experience in social interactions, where we often view only parts of faces. However, our understanding of predictions of the whole face from its parts remains limited. This study investigated this by dividing faces into the top and bottom halves (Study 1) and the forehead, eyes, nose, and mouth (Study 2). We compared how attractiveness was predicted from these parts versus when the whole face was fully observed. In the findings, overestimations occurred when predicting from the eyes (or the top half). Similarly, predictions from the nose resulted in overestimations, though to a lesser extent. In contrast, no difference was found between the predicted and observed attractiveness of the whole face when predicting from the mouth (or the bottom half). Further analysis revealed that the eyes were the most significant predictor of facial attractiveness across all facial features. Interestingly, higher attractiveness of the eyes was associated with a greater extent of overestimations in predictions from the eyes, whereas predictions from other parts exhibited a reduced extent of overestimations. These findings implied that predictions were influenced by the eyes, underscoring the critical role the eyes play in the process of predicting facial attractiveness.

Are perceptions of the psychotherapist affected by the audiovisual quality of a teletherapy session?

OBJECTIVE

Remote forms of psychotherapy became more common during the COVID-19 pandemic, increasing the importance of understanding how technological factors might affect remote treatment. Past research on other modes of communication suggests that perceptions can be influenced when the audiovisual quality of online communication is distorted. The aim of the current research was to examine the potential influence of visual or audio distortions during online therapy.

METHOD

263 participants judged the interpersonal characteristics and skill of a psychotherapist after viewing segments of treatment sessions in either a video or audio-only format and where the presentation was either clear or distorted.

RESULTS

Contrary to expectations, participants who viewed a poorer quality version of a therapy segment perceived the therapist to have more positive interpersonal characteristics than those who saw a segment of higher quality. There was no reliable difference in perception of the therapist's skill as a function of segment quality.

CONCLUSION

The findings from the study suggest that perceptions of a therapist are not adversely affected if the video or audio quality of a remote therapy session is less than ideal. Therefore, these technical aspects of online treatment may not need to be a top concern.

The impact of the use of masks on trait judgments and face recognition

Although effective in reducing virus transmission, face masks might compromise face recognition and trait judgments. With this study, we aimed to observe the influence of masks on face recognition and trait judgments-more specifically, in trustworthiness, dominance, and distinctiveness judgments. Also, we wanted to observe the possible influence of trait judgments on facial recognition for masked and unmasked faces, which has never been done before. For that, we conducted an online study where 140 participants observed and made trait judgments of masked and unmasked faces in a within-subjects design. After a distractive task, participants performed a recognition memory test. As expected, we observed a better recognition of faces shown without a mask during the study phase, which allowed the holistic processing of the faces. The worst performance was found for faces encoded with a mask but tested without it, occurring simultaneity disruption in holistic face processing and the violation of the encoding specificity principle. Regarding the trait judgments, unmasked faces were considered more distinctive, and masked faces were considered more trustworthy. More interestingly, we can conclude that facial distinctiveness predicts face recognition, regardless of mask use. In contrast, dominance judgments only predicted face recognition when faces were presented without a mask. When faces were exposed with masks, trustworthiness overrides dominance, becoming more critical to recognizing faces. We can interpret these results from an evolutionary perspective.

Unveiling why race does not affect the mask effect on attractiveness: but gender and expression do

Studies show that surgical face masks can have both positive and negative effects on attractiveness. Race has been implicated as a moderator of the size of this mask effect. Here, the moderating effects of expression, race and gender are explored. The mask effect was more positive for males than for females, for neutral faces than for smiling faces, and there were differences between the races. Further, the effect of unmasked attractiveness was partialled out for each image, which removed the race effects, but the gender and expression effects remained. It is suggested that racial differences previously observed in the mask effects are a consequence of differences in attractiveness of the faces sampled from those races. Re-analysis of previous research that showed race effects also demonstrates how they are better explained as attractiveness effects rather than race effects. This explanation can provide order to the different findings observed across the literature.

Assessing Preferences of Facial Appearance in Transgender and Gender Nonbinary Patients

BACKGROUND

We designed a survey to evaluate preferences of facial appearance in transgender male (TM), transgender female (TF) and gender nonbinary patients to better inform goals of facial gender affirming surgery (FGAS) in gender nonbinary patients.

METHODS

TM/TF and nonbinary patients > 18 years old were identified via retrospective chart review and distributed an anonymized survey via email from October 3 to December 31, 2022. To assess facial preferences, AI-generated and open-source portraits were edited to create five image sets with a range of features from masculine to feminine for the forehead, mandible/chin and hairline. Data were analyzed using Fisher's exact tests and ANOVA in R-Studio.

RESULTS

Survey response rate was 32% (180 patients identified via chart review, 58 respondents; TM = 5, TF = 39, nonbinary = 14). TM and TF patients as well as TF and nonbinary patients had significantly different preferences for all regions (p < 0.005; all series), while TM and nonbinary patients did not (p => 0.05; all series). TF patients consistently selected 4s with neutral or more feminine features. TM and nonbinary patients, however, demonstrated no consistent preference for either male or female features but rather a range of responses spanning extremes of both masculine and feminine options. When stratified by sex assigned at birth, nonbinary patients consistently identified preferences opposite to their assigned gender.

CONCLUSION

Gender nonbinary and TM patients appear to have uniquely individual preferences regarding facial appearance that do not fit into classically masculine or feminine patterns/phenotypes. As a result, we recommend individualized preoperative planning for FGAS to achieve the optimal result in these patient populations.

Face coverings increase apparent honesty and cooperativeness

People readily make inferences about trait-like characteristics of another person's face. Since the recent global COVID-19 pandemic, the widespread use of hygienic face masks has led to large proportions of the face being covered. We investigated the effect of face masks on the inference of prosocially relevant characteristics, namely cooperativeness and honesty. Portraits of participants of previous studies from which we knew their "true" prosocial tendencies served as stimuli. These facial stimuli were presented once with and once without a hygienic face mask to 60 naïve participants who rated the faces for cooperativeness and honesty. Results revealed that wearing face masks made people generally appear more cooperative and more honest than without a mask, but that these ratings were unrelated to the true prosocial tendencies of these people. Together, these findings have important implications for social interactions, particularly in contexts where nonverbal communication is essential, such as in healthcare settings, job interviews, and social gatherings.

When less is not more: the effect of transparent masks on facial attractiveness judgment

During the COVID-19 pandemic, face masks have been widely used in daily life. Previous studies have suggested that faces wearing typical masks that occlude the lower half of the face are perceived as more attractive than face without masks. However, relatively little work has been done on how transparent masks that reveal the lower half of the face affect the judgment of facial attractiveness. To investigate the effect of transparent masks on the perceived attractiveness, in the current study, we asked participants to rate the attractiveness of faces without masks and with a typical opaque mask and a transparent mask. The results showed that faces wearing opaque masks were evaluated as more attractive than those wearing transparent masks or no masks. The benefit of opaque masks was more pronounced in faces that were initially evaluated as unattractive. Interestingly, wearing transparent masks decreased the perceived attractiveness of faces but only for the faces initially rated as attractive, possibly because of the visual distortion of the lower half of the face by transparent masks. In summary, we found that opaque and transparent masks have different effects on perceived attractiveness, depending on the attractiveness of faces. Given benefits of transparent masks in socio-emotional and cognitive processing, it would be important to further understand the effect of transparent masks on face information processing.

Remembering to whom we transmit information during pandemics: the effect of face masks on destination memory

Considering the global pandemic we currently experience, face masks have become standard in our daily routine. Even though surgical masks are established as a safety measure against the dissemination of COVID-19, previous research showed that their wearing compromises face recognition. Consequently, the capacity to remember to whom we transmit information-destination memory-could also be compromised. In our study, through a between-participants design (experiment 1) and a within-participants design (experiment 2), undergraduate students have to transmit Portuguese proverbs to masked and unmasked celebrity faces. Following our hypothesis, participants who shared information with masked faces had worse destination memory performance than those who shared information with unmasked faces. Also, we observed lower recognition for masked faces compared to unmasked faces. These results were expected since using a surgical mask affects facial recognition, thus making it harder to recognize a person to whom information was previously transmitted. More importantly, these results also support the idea that variables associated with the recipient's face are important for destination memory performance.

Post COVID-19, still wear a face mask? Self-perceived facial attractiveness reduces mask-wearing intention

With the emerging post-COVID era, wearing face masks has become a domain of personal choice. Then, who wants to continue wearing a mask when it is no longer mandatory? In this article, we expect and examine the role of self-perceived facial attractiveness in predicting mask-wearing intention and its mechanism across three studies (total N = 1,030). Studies 1 and 2 demonstrated that individuals with high (vs. low) self-perceived attractiveness were less willing to wear a mask, due to a weaker endorsement of the belief that mask-wearing enhances their perceived attractiveness (i.e., mask attractiveness belief). Study 3 further revealed that this mediational association was stronger in situations where the need to deliver a favorable impression was high (job interview context) versus low (walking a dog context). Overall, we provide a novel finding that self-perceived attractiveness has significant effects on mask-wearing intention via mask attractiveness belief in the post-pandemic of COVID-19. Our findings suggest that mask-wearing can shift from being a self-protection measure during the COVID-19 pandemic to a self-presentation tactic in the post-pandemic era.

Impact of face masks and sunglasses on attractiveness, trustworthiness, and familiarity, and limited time effect: a Japanese sample

Many studies conducted after the COVID-19 pandemic have examined the relationship between changes in social traits, such as attractiveness and wearing face masks. However, most studies examine the effect of wearing face masks at a single time point, and the time effect is not known. Additionally, few studies address wearing sunglasses, another facial occluding item. This study examined the effects of facial occluding (unoccluded face, face masks, sunglasses, or both) on perceived attractiveness, trustworthiness, and familiarity at two time points, September 2020, six months after the start of the COVID-19 pandemic, and April 2022, almost two years later, using Japanese higher and lower attractive faces. Results showed that only lower attractive faces wearing face masks had a time effect on attractiveness and familiarity and no time effect on social traits in higher attractive faces. Perceived all social traits were the highest for unoccluded faces, and faces wearing face masks had the same level of attractiveness and familiarity as unoccluded faces. Perceived trustworthiness was higher for unoccluded faces, faces wearing face masks, sunglasses, and both sunglasses and face masks, respectively. Additionally, faces wearing both sunglasses and face masks had the lowest perceived all social traits. These findings suggest that the positive and time effects of wearing face masks are limited in Japan, suggesting a greater positive impact of unoccluded faces. They also suggest that the negative impact of wearing sunglasses is significant.

Occlusion of faces by sanitary masks improves facial attractiveness of other races

Recent studies provide mixed results regarding whether the perception of facial attractiveness is increased or decreased by partial occlusion with a sanitary mask. One set of studies demonstrated that occluding the bottom half of a face increased facial attractiveness. This effect is thought to occur because the occluded area is interpolated by an average facial representation that is perceived as attractive. However, several groups of studies showed that partial occlusion can increase or decrease perceived attractiveness depending on the attractiveness of the original (unoccluded) face, due to regression to the mean. To reconcile this inconsistency, we propose that the occluded area is interpolated not by an average facial representation, but by a template of moderate attractiveness, shaped by the distribution of each viewer's experience. This hypothesis predicts an interaction between occlusion and the attractiveness of the original face so that occluded attractive faces are rated as less attractive, while occluded unattractive faces are rated as more attractive. To examine this hypothesis, the present study used attractiveness-rating tasks with mask-free versus masked faces in own-race and other-races categories. Viewers were familiar with own-race faces and unfamiliar with other-races faces. If moderate-attractiveness interpolation were the explanatory factor, the interaction between the occlusion and the attractiveness of the original face should be found only in the rating of own-race faces. Consistent with this hypothesis, the interaction between the occlusion and the attractiveness of the original faces was significant only for the own-race faces. Specifically, wearing a sanitary mask decreased the facial attractiveness of attractive faces in the own-race, while it increased the attractiveness regardless of the level of facial attractiveness in other-races. These findings suggest that the occluded area of own-race faces is interpolated by a facial template of moderate attractiveness. The other-races template could be developed using familiar exemplars such as celebrities. Thus, interpolation by such a template should result in elevated attractiveness relative to that by an own-race template. Accordingly, the apparent inconsistency in the literature regarding the effect of partial occlusion on physical attractiveness can be explained in terms of differences in the template involving interpolation of the occluded area.

Face masks have a limited effect on the feeling of being looked at

Introduction

Wearing face masks has been promoted as an effective measure to reduce the spread of COVID-19. Because face masks cover a major part of the face, they have detrimental effects on various aspects of social cognition. Yet, a highly important feature of the face is not occluded by face masks: the eyes. The eyes play an important role in social interactions: knowing where another person is looking is of central importance when interacting with others. Recent research has reported an attentional shift toward the eye region as a consequence of the widespread exposure to face masks. However, no study has yet investigated the influence of face masks on the perception of eye gaze direction. Here we investigated whether face masks have an effect on the feeling of being looked at. Assuming an attentional shift toward the eyes, we might expect more accurate gaze perception in faces wearing face masks.

Methods

Sixty-five participants decided for a series of realistic avatar faces whether each face was making eye contact or not. Half of the faces wore face masks, the other half did not. For each participant and separately for each condition (mask vs. no mask), we calculated the cone of direct gaze (CoDG), a commonly used measure to quantify the range of gaze angles within which an observer assumes mutual gaze.

Results

Contrary to our expectations, results show that mutual gaze is not recognized more accurately in masked faces. Rather, the CoDG was, on average, slightly wider for faces wearing masks compared to faces without masks.

Discussion

Notwithstanding the relatively small effect of face mask, these findings potentially have implications on our social interactions. If we inadvertently feel looked at by an onlooker, we may react inappropriately by reciprocating the alleged approach orientation.

The impact of COVID-19 on memory: Recognition for masked and unmasked faces

Considering the current state of the worldwide pandemic, it is still common to encounter people wearing face protection masks. Although a safety measure against COVID-19, face masks might be compromising our capacity for face recognition. We conducted an online study where 140 participants observed masked and unmasked faces in a within-subjects design and then performed a recognition memory task. The best performance was found when there were no masks either at study and test phase, i.e., at the congruent unmasked condition. The worst performance was found for faces encoded with a mask but tested without it (i.e., masked-unmasked incongruent condition), which can be explained by the disruption in holistic face processing and the violation of the encoding specificity principle. Interestingly, considering the unmasked-masked incongruent condition, performance was probably affected by the violation of the encoding specificity principle but protected by holistic processing that occurred during encoding.

The Effect of Wearing a Mask on Facial Attractiveness

Background

The COVID-19 pandemic necessitated masking in public spaces. Masks may impact the perceived attractiveness of individuals and hence, interpersonal relations.

Objectives

To determine if facial coverings affect attractiveness.

Methods

An online survey was conducted using 114 headshot images, 2 each-unmasked and masked-of 57 individuals. Two hundred and seven participants rated them on an ordinal scale from 1 (least attractive) to 10 (most attractive). Parametric and nonparametric tests were performed, as appropriate, for comparison.

Results

For the first quartile, the average rating increased significantly when wearing a mask (5.89 ± 0.29 and 6.54 ± 0.67; P = 0.01). For control images ranked within the fourth quartile, the average rating decreased significantly when wearing a mask (7.60 ± 0.26 and 6.62 ± 0.55; P < 0.001). In the female subgroup (n = 34), there was a small increase in average rating when masked, whereas in the male subgroup (n = 23), there was a small decrease in average rating when masked, but the change was not statistically significant (P > 0.05). For unmasked female images ranked within the first quartile, the average rating increased significantly when wearing a mask (5.77 ± 0.27 and 6.76 ± 0.36; P = 0.001). For the female subgroup with mean ratings within the fourth quartile, the average decreased significantly when wearing a medical mask (7.53 ± 0.30 and 6.77 ± 0.53; P < 0.05). For unmasked male images ranked within the first quartile, the average rating increased when wearing a medical mask but the change was not statistically significant (P > 0.05), whereas for the control male images within the fourth quartile, the average rating decreased significantly when masked (7.72 ± 0.18 and 6.50 ± 0.54; P < 0.05).

Conclusions

While wearing a facial covering significantly increased attractiveness for images less attractive at baseline, and decreased attractiveness for those that are more attractive at baseline; it did not cause a significant overall change in attractiveness in the study population.

Level of Evidence 5

The Attractiveness of Masked Faces Is Influenced by Race and Mask Attitudes

This study tests the influence of wearing a protective face mask on the perceived attractiveness of the wearer. Participants who identified as White, and who varied in their ideological stance toward mask wearing, rated the attractiveness of facial photographs. The photos varied in baseline attractiveness (low, medium, and high), race (White and Asian), and whether or not the face was wearing a protective mask. Attitudes regarding protective masks were measured after the rating task using a survey to identify participants as either pro- or anti-mask. The results showed that masked individuals of the same race were generally rated as more attractive than unmasked individuals, but that masked individuals of another race were rated as less attractive than unmasked individuals. Moreover, pro-mask participants rated masked individuals as generally more attractive than unmasked individuals, whereas anti-maskers rated masked individuals as less attractive. A control experiment, replicating the procedure but replacing the protective masks with a partially occluding notebook, showed that these effects were mask-specific. These results demonstrate that perceived attractiveness is affected by characteristics of the viewer (attitudes toward protective masks), their relationship to the target (same or different race), and by circumstances external to both (pandemic).

Robustness of the aging effect of smiling against vertical facial orientation

Background: Previous studies have shown that the association between smiling and youth is a misconception; smiling faces have been estimated to be older than neutral faces. Previous studies have indicated that this aging effect of smiling (AES) is due to eye wrinkles caused by the facial action of smiling. However, whether holistic processing for facial expressions is involved in AES has not been investigated. The present study aimed to clarify these issues. Methods: Participants were recruited to participate in an online experiment that had a 3 (facial expression: smiling/neutral/surprised) × 2 (facial orientation: upright/inverted) mixed design. Participants were presented with an upright or inverted face for each expression (neutral, smiling, and surprised) and were asked to estimate the individual's age. Results: In total, 104 participants were included in the analysis. The results show that smiling faces were estimated to be older than neutral faces, whereas there was no significant difference between upright and inverted faces. Conclusions: Our findings suggest that AES is not dependent on holistic processing.

Unattractive faces are more attractive when the bottom-half is masked, an effect that reverses when the top-half is concealed

Facial attractiveness in humans signals an individual's genetic condition, underlying physiology and health status, serving as a cue to one's mate value. The practice of wearing face masks for prevention of transmission of airborne infections may disrupt one's ability to evaluate facial attractiveness, and with it, cues to an individual's health and genetic condition. The current research investigated the effect of face masks on the perception of face attractiveness. Across four studies, we tested if below- and above-average attractive full faces are equally affected by wearing facial masks. The results reveal that for young faces (Study 1) and old faces (Study 2) a facial mask increases the perceived attractiveness of relatively unattractive faces, but there is no effect of wearing a face mask for highly attractive faces. Study 3 shows that the same pattern of ratings emerged when the bottom-half of the faces are cropped rather than masked, indicating that the effect is not mask-specific. Our final Study 4, in which information from only the lower half of the faces was made available, showed that contrary to our previous findings, highly attractive half-faces are perceived to be less attractive than their full-face counterpart; but there is no such effect for the less attractive faces. This demonstrates the importance of the eye-region in the perception of attractiveness, especially for highly attractive faces. Collectively these findings suggest that a positivity-bias enhances the perception of unattractive faces when only the upper face is visible, a finding that may not extend to attractive faces because of the perceptual weight placed on their eye-region.

Beyond the beauty of occlusion: medical masks increase facial attractiveness more than other face coverings

The sanitary-mask effect (Miyazaki and Kawahara in Jpn Psychol Res 58(3):261–272, 2016) is the finding that medical face masks prompt an image of disease and thus result in lower ratings of facial attractiveness of the wearer. However, during the COVID-19 pandemic, medical masks have been found to increase attractiveness (Patel et al. in Plast Reconstruct Surg Glob Open 8(8), 2020) although this could have been a general effect of occlusion. To further explore this issue, female participants were presented with a series of male faces of low or high attractiveness that were occluded with a medical mask, cloth mask, book or not occluded and asked to rate them on attractiveness. The results show that faces were considered as most attractive when covered by medical masks and significantly more attractive when occluded with cloth masks than when not occluded. Contrary to expectation, base attractiveness did not interact with the type of occlusion, suggesting that this is not simply due to occlusion of negative features. The present findings are contrary to the sanitary-mask effect and explanations in terms of social desirability, and the association of medical masks with caregiving professions is explored.
