This study conducted a cross-sectional investigation of facial appearance dissatisfaction between patients before undergoing orthognathic surgery and a non-surgical sample to evaluate the potential influencing factors of facial appearance dissatisfaction. A sample of 354 participants completed a set of questionnaires concerning facial appearance dissatisfaction, interpersonal pressure, media pressure, and fear of negative appearance evaluation (112 patients, 242 controls). The patients reported higher facial appearance dissatisfaction, more media pressure, (...) more interpersonal pressure, and a greater fear of negative appearance evaluation among others than the control group. Moreover, regression analyses identified interpersonal pressure and fear of negative appearance evaluation as the main influencing factors on facial appearance dissatisfaction whether in the orthognathic patients or in the control groups. The associations between the perceptions of interpersonal pressure, fear of negative appearance evaluation, and facial appearance dissatisfaction support the possible utility of strengthening social experiences and psychological intervention in preventing and treating these appearance-concerns, especially for the orthognathic patients.

Dissatisfaction with facial appearance is one of the strongest contributors to body image disturbance among young Chinese females and leads to a series of psychological and behavioral disorders. By conducting behavioral and ERP experiments, this study illustrates how young females in China with facial dissatisfaction process different levels of facial attractiveness. Experiments 1 and 2 are behavioral experiments in which the dot-probe paradigm was used to explore the participant’s attentional bias to facial attractiveness. (...) The results showed that regardless of whether the face image was presented above or below the threshold, young females with facial dissatisfaction exhibited attentional orientation toward lowly attractive faces and attentional avoidance to both lowly and highly attractive faces, while the control group showed difficulty in attentional disengagement from highly attractive faces. In experiment 3, the learning-recognition task was used to examine mnemonic bias toward facial attractiveness among females with facial dissatisfaction, and EEG data were also recorded during the encoding and retrieval phases. The study found that young females with facial dissatisfaction exhibited a mnemonic preference for lowly attractive images at both the encoding and retrieving stages, with higher P1, N170, P2, and N300 induced by lowly attractive faces, while the control group preferred highly attractive faces. In conclusion, young females with facial dissatisfaction tend to exhibit attentional orientation and mnemonic bias toward lowly attractive faces. (shrink)

The human face conveys a myriad of social meanings within an overlapping array of features. Herein, we examine such features within the context of gender-emotion stereotypes. First we detail the pervasive set of gender-emotion expectations known to exist. We then review new research revealing that gender cues and emotion expression often share physical properties that represent a confound of overlapping features characteristic of low versus high facial maturity/dominance. As such, gender-related facial appearance and facial expression of (...) emotions often share social meaning and physical resemblance. Thus, stereotypic and phenotypic information conveyed by the face are intertwined—sometimes confounded, sometimes clashing. We discuss implications of this work for gender-emotion stereotypes, as well as for emotion and face processing more generally. (shrink)

Background: Clinical and experimental findings have suggested that insomnia is associated with altered emotion processing, such as facial emotion recognition and impairments in executive functions. However, the results still appear non-consensual and have recently been presented by a few number of studies. Accordingly, the aim of the present study was to investigate whether patients with Insomnia disorder will present alterations in recognition of facial emotions and that such alterations will be related to Executive Functions and that Insomnia Disorder (...) patients will exhibit a lower Executive Functions performance when compared to normal controls individuals. Method: A total of 11 individuals diagnosed with insomnia disorder and 15 control participants took part in the present cross-sectional study. They completed questionnaires covering socio-demographic data, a sleep and mood evaluation, and a cognitive assessment. Moreover, they underwent a computerized Facial Emotional Recognition test, consisting of facial emotion labeling and facial emotion matching. Results: Individuals with insomnia presented a lower recognition of facial expressions of fear and sadness in comparison to control volunteers. Perceptual Organization Index was found to be statistically significant lower in the insomnia group compared to the control group. There was a statistically significant association between facial recognition emotional and cognitive processes of in executive functions performance, especially in processes related to the inhibitory control, planning capacity, problem solving and cognitive flexibility in insomnia group. Conclusions: Insomnia disorder impairs the facial emotion recognition of the fear and sadness. Insomniacs with impairment in the facial emotion recognition had impaired performance of executive functions. There is a negative impact on processes related to cognitive-emotional capacity than on processes related to social-emotional recognition. Keywords: insomnia, facial emotional recognition, sleep deprivation, cognition, executive functions. (shrink)

Faces carry key personal information about individuals, including cues to their identity, social traits, and emotional state. Much research to date has employed static images of faces taken under tightly controlled conditions yet faces in the real world are dynamic and experienced under ambient conditions. A common approach to studying key dimensions of facial variation is the use of facial caricatures. However, such techniques have again typically relied on static images, and the few examples of dynamic caricatures have (...) relied on animating graphical head models. Here, we present a principal component analysis -based active appearance model for capturing patterns of spatiotemporal variation in videos of natural dynamic facial behaviours. We demonstrate how this technique can be applied to generate dynamic anti-caricatures of biological motion patterns in facial behaviours. This technique could be extended to caricaturing other facial dimensions, or to more general analyses of spatiotemporal variations in dynamic faces. (shrink)

Body Dissatisfaction The author concentrates on the preference of the values of "the cult of the body" increasingly affecting the behaviour of young people and their position in the value system relating to generally recognized values. Too much emphasis on physical beauty and outward appearance significantly determines behaviour and can lead to a reduction in values relating to the body and body shape but also to unhealthy eating disorders such as bulimia or anorexia nervosa. The focus is on (...) the pathological perception of the body, on how culture and cultural norms affect body dissatisfaction. A research questionnaire on universal values and the cult of the body (2006) was used. The research sample consisted of 508 respondents aged between 18 and 26 (292 women and 216 men). (shrink)

Previous studies have found that individuals from rural areas in Malaysia and in El Salvador prefer heavier women than individuals from urban areas. Several explanations have been proposed to explain these differences in weight preferences but no study has explored familiarity as a possible explanation. We therefore sought to investigate participants’ face preferences while also examining the facial characteristics of the actual participants. Our results showed that participants from rural areas preferred heavier-looking female faces than participants from urban areas. (...) We also found that the female faces from the rural areas were rated as looking heavier than the female faces from the urban areas. Our findings are consistent with the hypothesis that familiarity may be contributing to the differences found in face preferences between rural and urban areas given that people from rural and urban areas are exposed to different faces.

In this article, we review empirical evidence regarding the relationship between facial expression and emotion during infancy. We focus on differential emotions theory’s view of this relationship because of its theoretical and methodological prominence. We conclude that current evidence fails to support its proposal regarding a set of pre-specified facial expressions that invariably reflect a corresponding set of discrete emotions in infants. Instead, the relationship between facial expression and emotion appears to be more complex. Some facial (...) expressions may have different meanings in infants than in children and adults. In addition, nonemotion factors may sometimes lead to the production of “emotional” facial expressions. We consider alternative perspectives on the nature of emotion and emotional expression in infancy with particular focus on differentiation and dynamical systems approaches. (shrink)

The use of facial recognition technology (FRT) as a form of intelligence has recently made a prominent public appearance in the theater of war. During the early months of Russia's invasion of Ukraine, Ukrainian authorities relied on FRT as part of the country's defensive activities, harnessing the technology for a variety of purposes, such as unveiling covert Russian agents operating amid the Ukrainian population; revealing the identity of Russian soldiers who committed war crimes; and even identifying dead Russian (...) soldiers. This constellation of uses of FRT—in a war increasingly waged on the digital and information front—warrants ethical examination. The essay discusses some of the most serious concerns with FRT in the context of war, including the infringement of informational privacy; the indiscriminate and disproportionate harms it may inflict, particularly when the technology is coupled with social media intelligence; and the potential abuse of the technology once the fog of war dissipates. Some of these concerns parallel those to be found in nations that are not engulfed in war, but others are unique to war-torn settings. (shrink)

In Looking Away, Rei Terada revisits debates about appearance and reality in order to make a startling claim: that the purpose of such debates is to police feelings of dissatisfaction with the given world. Terada proposes that the connection between dissatisfaction and ephemeral phenomenality reveals a hitherto-unknown alternative to aesthetics that expresses our right to desire something other than experience "as is", even those parts of it that really cannot be otherwise.

BackgroundWe review original papers on ovarian-hormone status in two areas of emotional processing: facial emotion recognition and emotional memory. Ovarian-hormone status is operationalized by the levels of the steroid sex hormones 17β-estradiol and progesterone, fluctuating over the natural menstrual cycle and suppressed under oral contraceptive use. We extend previous reviews addressing single areas of emotional processing. Moreover, we systematically examine the role of stimulus features such as emotion type or stimulus valence and aim at elucidating factors that reconcile the (...) inconsistent results.MethodsWe followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and included papers published until September 2020 indexed in PubMed and Web of Science databases. Search terms were MeSH terms AND AND with representing our separately searched areas, resulting in, and. To be included, articles had to be written and published in English, examine healthy, non-pregnant adult women in their reproductive age, and measure or at least estimate levels of E2 and P4. In PubMed, the search was limited to humans and to the search term present in the title or abstract.ResultsFeatures of the provided stimulus material constitute a relevant influence that interacts with E2- and P4-related ovarian-hormone status. For instance, recognition of basic emotions appears to be more related to P4- than E2-levels. Quite consistent, OC intake was accompanied by impaired recognition accuracy of basic and also complex emotions, although not in a recent large-sample study assessing complex emotions. Memory recall of negative content was mainly enhanced by P4, especially after having been stressed.Discussion and ConclusionWe document the methodological diversity in the field, presumably contributing to the heterogeneity of results. More studies explicitly contrasting the early follicular phase, mid-cycle phase, mid-luteal, and OC intake while standardizing tasks are needed. Research would take advantage of using within-subject designs and accounting for the recognition of complex emotions. (shrink)

Past research has found that skin colouration, particularly facial redness, influences the perceived health and emotional state of target individuals. In the current work, we explore several extensions of this past research. In Experiment 1, we manipulated facial redness incrementally on neutral and angry faces and had participants rate each face for anger and health. Different red effects emerged, as perceived anger increased in a linear manner as facial redness increased. Health ratings instead showed a curvilinear trend, (...) as both extreme paleness and redness were rated as less healthy than moderate levels of red. Experiment 2 replicated and extended these findings by manipulating the masculinity of both angry and neutral faces that varied in redness. The results found the effect of red on perceived anger and health was moderated by masculine face structure. Collectively, these results show that facial redness has context dependent effects that vary based on facial expression, appearance, and differentially impact ratings of emotional states and health.

Prior research on facial beauty has suggested that the average female face in a population is perceived to be the most attractive face. This finding, however, is based on an image processing methodology that appears to be flawed. An alternative method for generating attractive faces is described and the findings using this procedure are compared with the reports of other experimenters. The results suggest that (1) beautiful female faces are not average, but vary from the average in a systematic (...) manner, and (2) female beauty can best be explained by a sexual selection viewpoint, whereby selection favors cues that are reliable indicators of fertility.

The proposal that there are specific adaptations for the expression and detection of pain appears premature on both conceptual and empirical grounds. We discuss criteria for the validation of a pain facial expression. We also describe recent findings from our lab on coping styles and pain expression, which illustrate the importance of considering individual differences when proposing evolutionary explanations.

The experience of pain appears to be associated, from early infancy and across pain stimuli, with a consistent facial expression in humans. A social function is proposed for this: the communication of pain and the need for help to observers, to whom information about danger is of value, and who may provide help within a kin or cooperative relationship. Some commentators have asserted that the evidence is insufficient to account for the consistency of the face, as judged by technical (...) means or in the perceptions of observers, or that facial expression is epiphenomenal to a gross behavioural defensive response to pain. The major criticism is that it is unnecessary to invoke evolutionary mechanisms beyond the emergence of an unconditioned facial response to pain in neonates, subsequently shaped and maintained by instrumental and social reinforcement throughout life. These criticisms are addressed, acknowledging the need for further data to address some, and elaborating the areas in which evolutionary and operant mechanisms would predict different behavioural interactions, rather than acting synergistically. Several supportive commentaries propose extending evolutionarily-based hypotheses to sex differences, the complexities of others' responses within the social relationship, and the role of empathy. A number of commentators provided valuable suggestions for experimental paradigms or methodological issues. Overall, addressing these issues indicates the need for further conceptual development and for collection of data specifically in relation to these hypotheses. (shrink)

Foveated stimuli receive visual processing that is quantitatively and qualitatively different from nonfoveated stimuli. At normal interpersonal distances, people move their eyes around another’s face so that certain features receive foveal processing; on any given fixation, other features therefore project extrafoveally. Yet little is known about the processing of extrafoveally presented facial features, how informative those extrafoveally presented features are for face perception (e.g., for assessing another’s emotion), or what processes extract task-relevant (e.g., emotion-related) cues from facial features (...) that first appear outside the fovea, and how these processes are implemented in the brain.

Gender-based differences in body image dissatisfaction are not conclusive. Women’s body experiences and their impact on sexual satisfaction may advance knowledge on how heterosexual, bisexual, and lesbian women internalize heterosexist values. In this study, we quantitatively examined the degree of body image and sexual dissatisfaction experienced by heterosexual, bisexual, and lesbian women, to determine whether body dissatisfaction can predict sexual dissatisfaction. Three hundred and fifty-four women completed an online survey measuring body and sexual dissatisfaction. No (...) sexual orientation-based differences were observed in body or sexual dissatisfaction; however, body concerns were found to have less influence on sexual dissatisfaction in lesbian women compared to heterosexual and bisexual women. Standards of beauty remain constant among all women, yet removing themselves from the male gaze may be interpreted as a protective factor which shields women from expressing concern about their appearance during sexual activity.

Facial muscle activities are essential for the appearance and communication of human beings. Therefore, exploring the activation patterns of facial muscles can help understand facial neuromuscular disorders such as Bell’s palsy. Given the irregular shape of the facial muscles as well as their different locations, it should be difficult to detect the activities of whole facial muscles with a few electrodes. In this study, a high-density surface electromyogram system with 90 electrodes was used to (...) record EMG signals of facial muscles in both healthy and Bell’s palsy subjects when they did different facial movements. The electrodes were arranged in rectangular arrays covering the forehead and cheek regions of the face. The muscle activation patterns were shown on maps, which were constructed from the Root Mean Square values of all the 90-channel EMG recordings. The experimental results showed that the activation patterns of facial muscles were distinct during doing different facial movements and the activated muscle regions could be clearly observed. Moreover, two features of the activation patterns, 2D correlation coefficient and Centre of Gravity were extracted to quantify the spatial symmetry and the location of activated muscle regions respectively. Furthermore, the deviation of activated muscle regions on the paralyzed side of a face compared to the healthy side was quantified by calculating the distance between two sides of CGs. The results revealed that corr2 of the activated facial muscle region in Bell’s palsy subjects was significantly lower than that in healthy subjects, while CG distance of activated facial region in Bell’s palsy subjects was significantly higher than that in healthy subjects. The correlation between corr2 of these regions and Bell’s palsy [assessed by the Facial Nerve Grading Scale 2.0] was also significant in Bell’s palsy subjects. The spatial information on activated muscle regions may be useful in the diagnosis and treatment of Bell’s palsy in the future. (shrink)

Deficits in recognition of facial expressions of emotions are considered to be an important factor explaining impairments in social functioning and affective reactions of schizophrenic patients. Many studies confirmed such deficits while controversies remained concerning the emotion valence and modality. The aim of the study was to explore the process of recognizing facial expressions of emotion in the group of schizophrenic patients by analyzing the role of emotion valence, modality and gender of the model. Results of the group (...) of 35 patients and 35 matched controls indicate that while schizophrenic patients show general impairment in recognizing facial expressions of both positive and the majority of negative emotions, there are differences in deficits for particular emotions. Expressions also appeared to be more ambiguous for the patients while variables connected with gender were found less significant. (shrink)

Many studies demonstrate that people form their first impression of a stranger based on facial appearance, and these impressions influence their subsequent decisions and behaviors. However, much less research has examined the factors that moderate the accuracy of first impressions based on a photo of face. The present study included three experiments to explore gender differences in the accuracy of impressions based on faces. The results showed that people judge facial attractiveness more accurately for female faces than (...) for male faces while giving more accurate wealth judgments for male faces than for female faces. Interestingly, although we did not find a significant correlation between confidence ratings and the accuracy of wealth rating, we recognized a significant moderate correlation between confidence ratings and the accuracy of attractiveness ratings when female participants rated male faces. To our knowledge, the present study is the first to reveal gender biases in the accuracy of impression judgments based on facial appearance. These findings imply a significant influence of traditional gender roles on accurate facial judgments. (shrink)

This review aims to identify (1) sources of knowledge and (2) important themes of the ethical debate related to surgical alteration of facial features in East Asians. This article integrates narrative and systematic review methods. In March 2014, we searched databases including PubMed, Philosopher’s Index, Web of Science, Sociological Abstracts, and Communication Abstracts using key terms “cosmetic surgery,” “ethnic*,” “ethics,” “Asia*,” and “Western*.” The study included all types of papers written in English that discuss the debate on rhinoplasty and (...) blepharoplasty in East Asians. No limit was put on date of publication. Combining both narrative and systematic review methods, a total of 31 articles were critically appraised on their contribution to ethical reflection founded on the debates regarding the surgical alteration of Asian features. Sources of knowledge were drawn from four main disciplines, including the humanities, medicine or surgery, communications, and economics. Focusing on cosmetic surgery perceived as a westernising practice, the key debate themes included authenticity of identity, interpersonal relationships and socio-economic utility in the context of Asian culture. The study shows how cosmetic surgery of ethnic features plays an important role in understanding female identity in the Asian context. Based on the debate themes authenticity of identity, interpersonal relationships, and socio-economic utility, this article argues that identity should be understood as less individualistic and more as relational and transformational in the Asian context. In addition, this article also proposes to consider cosmetic surgery of Asian features as an interplay of cultural imperialism and cultural nationalism, which can both be a source of social pressure to modify one’s appearance.

This study explored the relationship between both overall television viewing and romantic youth drama viewing, as well as of females’ concerns about boys’ attractiveness expectations on the one hand, and body image dissatisfaction on the other. Participants were 411 adolescent girls who completed self-report measures on body dissatisfaction, television viewing, and concerns about appearance expectations. Our results indicated that there was both a direct and indirect relationship between romantic youth drama viewing and body satisfaction. Girls who spent (...) more time watching romantic youth drama displayed lower levels of body satisfaction. In addition, romantic youth drama viewing had a significant positive impact on concerns about boys’ attractiveness expectations, which had an indirect effect on body satisfaction. (shrink)

Perfectionism is a multidimensional construct with both positive and negative aspects. Recently, the concept of appearance-oriented perfectionism has been introduced, which is associated with body image dissatisfaction and weight and shape control behaviors. The Physical Appearance Perfectionism Scale is a 12-item two-factor instrument developed to assess this new dimension of perfectionism. The aim of the study is to validate the Spanish version of PAPS among a representative sample of 850 male university students in Spain. Exploratory and confirmatory (...) factorial structure, internal consistency, convergent and concurrent validity, and associated predictor variables analyses have been carried out. Results showed that the Spanish version of the PAPS maintains the original factor structure with all items and proves to be a reliable instrument. Physical appearance-oriented perfectionism is associated with general perfectionism, higher body dissatisfaction, Eating Disorders and Muscle Dysmorphia symptomatology, and compulsive exercise, particularly in the Worry about Imperfection subscale. These variables also act as predictors of physical appearance perfectionism. The use of the PAPS-S and the analysis of its subscales is recommended in the context of body image-related pathologies such as Eating Disorders and Muscle Dysmorphia. (shrink)

Averageness is purportedly the result of stabilizing selection maintaining the population mean, whereas facial paedomorphosis is a product of directional selection driving the population mean towards an increasingly juvenile appearance. If selection is predominantly stabilizing, intermediate phenotypes reflect high genetic quality and mathematically average faces should be found attractive. If, on the other hand, directional selection is strong enough, extreme phenotypes reflect high genetic quality and juvenilized faces will be found attractive. To compare the effects of stabilizing and (...) directional selection on facial paedomorphosis (juvenilization), graphic morphing and editing techniques were used to alter the appearance of composite faces to make them appear more or less juvenile. Both facial models and judges of attractiveness were from the CSU-Long Beach campus. Although effect sizes for both preferences were large, the effect for averageness was nearly twice that found for juvenilization, an indication that stabilizing selection influences preferences for facial paedomorphosis more so than directional selection in contemporary humans.

Objective: Body dissatisfaction is a major risk factor underlying vulnerability to eating disorders. Laboratory settings suggest that body dissatisfaction could be improved by using evaluative conditioning (EC). The present study evaluates the feasibility of using an EC app in everyday life and the effects of its use on body dissatisfaction. Method: We designed a game-like app inspired by the Therapeutic Evaluative Conditioning app. 60 participants were randomly assigned to two conditions. Participants in the EC condition had to (...) pair photographs of their own body with positive photographs, while participants in the neutral condition had to pair photographs of their own body with neutral photographs. We tested the effect of use of the app on body dissatisfaction, drive for thinness, self-esteem, mood and eating behaviors. Results: Analysis revealed that participants in all conditions presented a significant decrease in body dissatisfaction and drive for thinness. However, contrary to our hypothesis, these reductions were not greater in the EC condition than in the neutral condition. Conclusions: This is the first study to evaluate the effects of an app-based EC intervention targeting body image. Results appear to be promising and the app could easily be implemented in an ecological setting as it is a low effort, attractive and accessible intervention. However, these findings do not support the idea that evaluative conditioning is responsible for the effects. Results are discussed. (shrink)

We report two experimental studies of human perceptions of robotic facial expressions while systematically varying context effects and the cultural background of subjects. Except for Fear, East Asian and Western subjects were not significantly different in recognition rates, and, while Westerners were better at judging affect from mouth movement alone, East Asians were not any better at judging affect based on eye/brow movement alone. Moreover, context effects appeared capable of over-riding such cultural differences, most notably for Fear. The results (...) seem to run counter to previous theories of cultural differences in facial expression based on emoticons and eye fixation patterns. We connect this to broader research in cognitive science – suggesting the findings support a dynamical systems view of social cognition as an emergent phenomenon. The results here suggest that, if we can induce appropriate context effects, it may be possible to create culture-neutral models of robots and affective interaction. (shrink)

At the intersection of aesthetics and the philosophy of perception lies a problem about representational images. When you look at Vermeer's View of Delft, do you in fact get to see Delft? It would be nice if we could answer in the affirmative, as it would so neatly explain many of our practices in engaging with images. Be it in churches, advertising, or psychology labs, we typically use images as substitutes for the immediate perception of things. Here is what I (...) claim: Images make it possible to see the objects they represent, and they do so because they can function in vision as perceptual mediators. A perceptual mediator is an object of perception by means of which we can perceive something wholly distinct from it. I show that, while such perceptual mediators may be exceptional in vision, in other sensory modalities they occur universally. Our sensory lives would be impoverished without the possibility of perceiving things mediately. In Chapter 1 I identify a fundamental dispute about images. The dispute is about whether images represent by making absent scenes appear to a viewer, or by merely copying the way an object or event looks. Many philosophers favour the idea that images merely copy how things look. In Chapter 2 I explain my dissatisfaction with the copy view. I lay out my main positive proposal in Chapter 3. How does the idea that images make absent objects visible fit with our current concept of perception? I formulate my answer through a study of the other sensory modalities. In audition, it is no mystery that sounds can make other things heard. My arguments forge a connection between images and sounds that has not been explored in recent work on representation or perception. I show how it offers an attractive solution to our problem. In Chapter 4, I argue that moreover, we may regard mediate perception as a purely sensory mode of perception. There is no need to rely on non-sensory or quasi-sensory effects of thought or cognition. Instead, coming to see a painted surface as an image consists in no more than discovering a previously unseen aspect of our visible surroundings. In Chapter 5 I consider at a more general level how visual images contribute to visual perception. Overall, I establish how visual representation has a structural place in our visual world. (shrink)

Williams and the many studies she considers appear to assume that voluntary amplification in facial expression of pain implies dissimulation. In fact, the behavioral ecology model of pain expression is consistent with amplification when subjects in pain are in the presence of others disposed to render aid, and that amplification may well be voluntary.

Several disciplines share an interest in the evolutionary selection pressures that shaped human physical functioning and appearance, psyche, and behavior. The methodologies invoked from the disciplines studying these domains are often based on different rhetorics, and hence may conflict. Progress in one field is thereby hampered from effective transfer to others. Topics at the intersection of anthropometry and psychometry, such as the impact of sexual selection on the hominin face, are a typical example. Since the underlying theory explicitly places (...) facial form in the middle of a causal chain as the mediating variable between biological causes and psychological effects, a particularly convenient conceptual and analytic scenario arises as follows. Modern morphometrics allows analysis of shape both “backwards” and “forwards” . The two computations are commensurate, hence the two kinds of effects can be compared and evaluated as directions in the same morphospace. We suggest translating the morphometric methodology of “Darwinian aesthetics” into this space, where psychological and other processes of interest can be coded commensurately. Such a translation permits researchers to relate the effects of biological processes on form to the perceptions of the same processes in one unified “psychomorphospace.”. (shrink)

ObjectiveStudies that examine disordered eating in samples of Asian individuals living in the United States frequently combine all individuals of Asian descent into a single group, which can obscure important differences between groups and their experiences of acculturation. The goal of the present study was to establish the relation of acculturation, internalization of appearance ideals, and religiosity as predicting body dissatisfaction and disordered eating in women of South and Southeast Asian descent.MethodWomen of SSEA descent aged 18–51 years completed (...) a battery of questionnaires that inquire about these variables. A path analysis was conducted with acculturation serving as the independent variable, religiosity and internalization of the thin ideal as mediators, and body dissatisfaction and disordered eating as dependent variables.ResultsDirect paths from acculturation to both body dissatisfaction and disordered eating were not significant. Thin ideal internalization completely accounted for the path from acculturation to both endogenous variables; whereas, religiosity did not significantly account for any indirect effect.DiscussionFor SSEA women, internalization of appearance ideals is a potentially greater risk factor for disordered eating than acculturation or religiosity. As this was an atemporal mediation analysis, more work needs to be done exploring predictors of internalization in this population and how that may impact the development of disordered eating.

In recent years the cognitive science community has witnessed the rise of a new, dynamical approach to cognition. This approach entails a framework in which cognition and behavior are taken to result from complex dynamical interactions between brain, body, and environment. The advent of the dynamical approach is grounded in a dissatisfaction with the classical computational view of cognition. A particularly strong claim has been that cognitive systems do not rely on internal representations and computations. Focusing on this claim, (...) we take as a starting point a question recently raised by Cliff and Noble: " if evolution did produce a design that used internal representations, how would we recognize it?" (Knowledge-based vision and simple visual machines, Philosophical Transactions of the Royal Society: Biological Sciences, 352 , 1165-1175, 1997). We will argue that cognitive science lacks a proper operationalization of the notion of representation, and therefore is unable to fruitfully discuss whether a particular system has representations or not. A basic method to detect representations in a physical system, grounded in isomorphism, turns out to be quite unconstrained. We will look at a practical example of this problem by examining the debate on whether or not van Gelder's (What might cognition be, if not computation? Journal of Philosophy, 92 , 345-381, 1995) controversial example of the Watt Governor is representational. We will conclude that cognitive science, as of yet, has no empirically applicable means to answer Cliff and Noble's question unequivocally. This makes the recent representationalism vs. anti-representationalism debate a debate for the sake of appearance. (shrink)

Previous studies have reported that general or photo-specific social media use was associated with women’s body dissatisfaction and body image disturbance. The current study replicated and expanded upon these findings by identifying the positive association between social media influencer viewing and intentions to change appearance. This study surveyed a sample of 7,015 adult female TikTok users in China regarding their social media influencer viewing frequency, self-objectification, social comparison tendencies when watching short videos, intentions to change appearance, and (...) demographics. The results showed that female TikTok users’ self-objectification mediated the association between their influencer viewing frequency and their intentions to change appearance. Furthermore, social comparison tendencies moderated the association between influencer viewing and intentions to change appearance in that the proposed association was stronger for female TikTok users who had lower social comparison tendencies when watching short videos, compared to female TikTok users who had higher social comparison tendencies. The counter-intuitive finding on social comparison tendencies indicated that women who have higher social comparison tendencies may be more aware of the negative influences and adjust their expectations. The observed association between social media influencer viewing and intentions to change appearance was statistically significant but trivial in terms of effect size. Although the result could warn policymakers and practitioners to design media and health literacy campaigns to cultivate body positivity, caution should be exercised when evaluating the practical implications.

PurposeThe fitness centers are settings for health promotion, yet may serve as a stage for counterproductive figure idealization. Such idealization may take the form of a drive toward the thin, the muscular, or lean body figure ideal, which all hold the potential to impel an experience of body appearance pressure and body dissatisfaction. The aim of this study was to explore figure idealization, body dissatisfaction, and experience of BAP in fitness instructors.Materials and MethodsFitness instructors, 70 males and (...) 236 females, were recruited through their facility chief executive officer and social media for a digital survey on mental health. Results are presented for body appreciation, body dissatisfaction, drive for muscularity, drive for leanness, questions on BAP, symptoms of eating disorders, and history of weight regulation and eating disorders.ResultsAttempts to gain body weight were reported by 17% of females and 53% of males, whereas ∼76% of males and females, respectively, reported to have attempted weight reduction. Reasons for body weight manipulation were predominantly appearance related, and 10–20% reported disordered eating behavior. Mean BAS-2 and EDI-BD were acceptable, but 28% of females were above clinical cutoff in EDI-BD, and mean DLS were high in both sexes. In total, 8% of females were above clinical cutoff in EDE-q, which corresponded well with the self-reported ED. Approximately 90% of the sample perceived BAP to be a societal issue and reported predominantly customers and colleagues to be the cause of their personal experience of BAP. Fewer than 50% knew of any actions taken by their employer to reduce BAP. There were few differences according to profession or educational level.ConclusionFitness instructors report BAP to affect them negatively, which may put them at risk of impaired mental health. Educational level did not protect against figure idealization and BAP. To care for their employees and to optimize their position as a public health promoter, the fitness industry should target BAP in health promotion programs. (shrink)

Compared with other communication media such as cellphones and video chat, teleoperated robots have a physical existence which increases the feeling of copresence. However, the appearance of a teleoperated robot is always the same regardless of the characteristics of its operator. Since people can determine their partner’s personality from his/her appearance, a teleoperated robot’s appearance might construct a personality that confuses the user. Our research focuses on establishing what kind of appearance of the telecommunication media could (...) prevent confusion and increase the feeling of copresence. In this study, we compare the appearance of three types of communication media. The result shows that, in the case of the human-like robot, the consistency of the personality judgment is better than in the case of the nonhuman-like robot. Also, we found that teleoperated robots transmit a more appropriate context-based atmosphere, while the video chat transmits more nonverbal information, such as facial expressions. (shrink)

Facial appearance changes with age and health affecting skin color as well as facial and head hair. Yet somehow the brain is able to see past shared structure and dynamic deformations to focus on subtle details that distinguish one face from another. This article argues that the brain takes an efficient approach to this problem using prior knowledge about the structure of faces in its analysis. It employs intrinsic norms to focus on subtle variations in the shared (...) face configuration that differentiate one face from another. The study reviews evidence that the brain uses multiple norms to extract face identity that these norms are shaped by visual experience, and that norm-based coding is well-suited to meeting the challenges of image-based face perception mentioned above. By encoding faces with reference to stored perceptual norms the visual system can focus on what is unique to each individual, allowing for the discrimination of thousands of faces despite their similarity.

According to the standard interpretation of Einstein’s field equations, gravity consists of mass-energy curving spacetime, and an additional physical force or entity—denoted by Λ (the ‘cosmological constant’)—is responsible for the Universe’s metric-expansion. Although General Relativity’s direct predictions have been systematically confirmed, the dominant cosmological model thought to follow from it—the ΛCDM (Lambda cold dark matter) model of the Universe’s history and composition—faces considerable challenges, including various observational anomalies and experimental failures to detect dark matter, dark energy, or inflation-field candidates. This (...) paper shows that Einstein’s Equivalence Principle entails two possible physical interpretations of General Relativity’s field equations. Although the field equations facially appear to support the standard interpretation—that gravity consists of mass-energy curving spacetime—the field equations can be equivalently understood as holding that gravitational effects instead result from mass-energy accelerating the metric-expansion of a second-order spacetime fabric superimposed upon an absolute, first-order Euclidean space, resulting in the observational appearance of spacetime curvature. This alternative interpretation of relativity is shown to be empirically equivalent to the standard interpretation of relativity, albeit with a changing value for Λ (which is similar to how Λ is understood in the conception of Λ as ‘quintessence’, but in this case takes Λ to be gravity). The reconceptualization is then shown to potentially resolve major observational anomalies for the ΛCDM model, including recent observations conflicting with ΛCDM predictions, as well as failures to directly detect dark matter, dark energy, and inflation field/particle candidates.

Wearing facial masks became a common practice worldwide during the COVID-19 pandemic. This study investigated (1) whether facial masks that cover adult faces affect 4- to 6-year-old children’s recognition of emotions in those faces and (2) whether the duration of children’s exposure to masks is associated with emotion recognition. We tested children from Switzerland (N = 38) and Brazil (N = 41). Brazil represented longer mask exposure due to a stricter mandate during COVID-19. Children had to choose a (...) face displaying a specific emotion (happy, angry, or sad) when the face wore either no cover, a facial mask, or sunglasses. The longer hours of mask exposure were associated with better emotion recognition. Controlling for the hours of exposure, children were less likely to recognise emotions in partially hideen faces. Moreover, Brazilian children were more accurate in recognising happy faces than Swiss children. Overall, facial masks may negatively impact children’s emotion recognition. However, prolonged exposure appears to buffer the lack of facial cues from the nose and mouth. In conclusion, restricting facial cues due to masks may impair kindergarten children’s emotion recognition in the short run. However, it may facilitate their broader reading of facial emotional cues in the long run. (shrink)
