RESUMO

Videos glamourising disordered eating practices and body image concerns readily circulate on TikTok. Minimal empirical research has investigated the impact of TikTok content on body image and eating behaviour. The present study aimed to fill this gap in current research by examining the influence of pro-anorexia TikTok content on young women's body image and degree of internalisation of beauty standards, whilst also exploring the impact of daily time spent on TikTok and the development of disordered eating behaviours. An experimental and cross-sectional design was used to explore body image and internalisation of beauty standards in relation to pro-anorexia TikTok content. Time spent on TikTok was examined in relation to the risk of developing orthorexia nervosa. A sample of 273 female-identifying persons aged 18-28 years were exposed to either pro-anorexia or neutral TikTok content. Pre- and post-test measures of body image and internalisation of beauty standards were obtained. Participants were divided into four groups based on average daily time spent on TikTok. Women exposed to pro-anorexia content displayed the greatest decrease in body image satisfaction and an increase in internalisation of societal beauty standards. Women exposed to neutral content also reported a decrease in body image satisfaction. Participants categorised as high and extreme daily TikTok users reported greater average disordered eating behaviour on the EAT-26 than participants with low and moderate use, however this finding was not statistically significant in relation to orthorexic behaviours. This research has implications for the mental health of young female TikTok users, with exposure to pro-anorexia content having immediate consequences for internalisation and body image dissatisfaction, potentially increasing one's risk of developing disordered eating beliefs and behaviours.

RESUMO

Introduction: daily, workers in beauty salons and parlors use different cosmetic products made of various chemicals. This study aimed to determine the knowledge, practices, and self-reported health outcomes related to chemical use and safety among workers in beauty salons and parlors. Methods: a quantitative, cross-sectional descriptive study was conducted among 145 participants, randomly selected using a simple random sampling design. A self-administered questionnaire was used to assess the Knowledge, practices, and self-reported health outcomes related to chemical safety. Pearson´s correlation was used to assess the correlation between perception, awareness, and other study determinants. Results: fifty-seven percent of participants had been working with chemicals for more than two years, and only 5% were smokers. There was a positive relationship between age and years of experience in the beauty and salon industry (r= 0.385; p < 0.001), while significant positive correlations between knowledge score with educational levels (r=0.444; p= <0.001) and formal training as a salon and beauty parlor worker (r=0.504; p= <0.001) were also found. Participants also reported symptoms such as headache (43%), nausea (23%), skin irritation (48%), eye irritation (39%), and respiratory illness-related symptoms (62%). Conclusion: there is a need for health and safety training in beauty salons and parlors, with emphasis on the correct use of personal protective equipment (PPE). The findings of this study may serve as the baseline for the development of safety policies for all beauty salons and parlors in South Africa.

RESUMO

Urban waterfront areas are dynamic interfaces where human and natural systems converge, forming complex ecosystems that encompass social, economic, and environmental elements. These areas offer ecological benefits and aesthetic experiences. However, a disparity between social aesthetic preferences and vegetation diversity along riverbanks impedes the integration of ecological and aesthetic values. To address this, a plant community optimization strategy based on a coupling coordination degree model (CCDM) is proposed. Using the Xietang River in Suzhou, China as a case study, surveys were conducted on 33 woody plant plots and 60 herbaceous plant plots, assessing plant diversity with Shannon-Wiener, richness, and Pielou indices. Landscape beauty was evaluated by 87 respondents using the Scenic Beauty Estimation method. Using six representative plant communities as mediators, CCDM was applied to quantitatively analyze the coordination between plant diversity and aesthetics. Based on this analysis and considering factors influencing plant diversity and scenic beauty, plant community optimization strategies were devised to enhance the coordinated development of ecological diversity and aesthetics, fostering a synergistic improvement in ecological and aesthetic quality. Results revealed a range of coupling coordination across plant communities (0.203 to 0.947), encompassing various types. Linear regression analysis demonstrated a non-linear relationship between plant diversity and landscape beauty, influenced by independent yet partially overlapping factors. Hence, both aspects should be simultaneously considered in the planning and enhancement of riverbank areas. The coupling coordination degree offers a comprehensive understanding of harmonizing plant diversity and aesthetic value, providing a quantitative and objective approach to integrated research. This perspective extends beyond urban waterfront landscapes, holding significance for achieving dual goals of ecology and social services in urban design and landscape management.

RESUMO

Prior research has produced mixed findings regarding whether women feel more attractive during the fertile phase of the menstrual cycle. Here, we analyzed cycle phase and hormonal predictors of women's self-perceived attractiveness (SPA) assessed within a daily diary study. Forty-three women indicated their SPA, sexual desire, and interest in their own partners or other potential mates each day across 1-2 menstrual cycles; saliva samples collected on corresponding days were assayed for estradiol, progesterone, and testosterone; and photos of the women taken at weekly intervals were rated for attractiveness. Contrary to some prior studies, we did not find a significant increase in SPA within the estimated fertile window (i.e., cycle days when conception is possible). However, within-cycle fluctuations in progesterone were significantly negatively associated with shifts in SPA, with a visible nadir in SPA in the mid-luteal phase. Women's sexual desire and SPA were positively associated, and the two variables fluctuated in very similar ways across the cycle. Third-party ratings of women's photos provided no evidence that women's SPA simply tracked actual changes in their visible attractiveness. Finally, for partnered women, changes in SPA correlated with shifts in attraction to own partners at least as strongly as it did with shifts in fantasy about extra-pair partners. Our findings provide preliminary evidence for the idea that SPA is a component of women's sexual motivation that may change in ways similar to other hormonally regulated shifts in motivational priorities. Additional large-scale studies are necessary to test replication of these preliminary findings.

RESUMO

The present study employed dictator game and ultimatum game to investigate the effect of facial attractiveness, vocal attractiveness and social interest in expressing positive ("I like you") versus negative signals ("I don't like you") on decision making. Female participants played against male recipients in dictator game and ultimatum game while played against male proposers in ultimatum game. Results showed that participants offered recipients with attractive faces more money than recipients with unattractive faces. Participants also offered recipients with attractive voices more money than recipients with unattractive voices, especially under the positive social interest condition. Moreover, participants allocated more money to recipients who expressed positive social interest than those who expressed negative social interest, whereas they would also expect proposers who expressed positive social interest to offer them more money than proposers who expressed negative social interest. Overall, the results inform beauty premium for faces and voices on opposite-sex economic bargaining. Social interest also affects decision outcomes. However, the beauty premium and effect of social interest varies with participants' roles.

RESUMO

Affective responses can influence evaluative judgments, but how are subjective beauty ratings affected by references to morally contentious elements in aesthetic stimuli? In an online experiment (N = 460), we investigated the relationship between two types of descriptive texts (Neutral vs. Negative) and the beauty ratings of 25 photographs that depict sources of environmental pollution. For each photograph, the neutral descriptive text contained general information, whereas the negative descriptive text addressed the pollution source. Further, we explored whether this relationship is mediated by changes in positive and negative affect, and how it interacts with the biospheric values of participants. Our results showed that (1) participants in the Negative Condition rated the photographs as less beautiful than in the Neutral Condition, (2) this relationship was partially mediated by changes in negative affect, and (3) in the Negative Condition, participants with higher levels of biospheric values rated the photographs as less beautiful. Our results indicate that individual values, as well as affective responses induced by aesthetic stimuli, directly influence subjective beauty. This aligns with current theoretical frameworks and fills a gap in experimental research. Finally, we discuss limitations and directions for future studies. PSYCHINFO CLASSIFICATION CODE: 2340.

RESUMO

BACKGROUND: Improved skin appearance is closely linked to higher self-esteem, favorable first impressions, and enhanced quality of life, with skincare products often being formulated with biostimulatory and regenerative ingredients to both enhance skin health and provide psychological benefits. Certain components, such as phospholipids and botanicals, may not only improve skin quality, but also impact mood, romantic bonding, and sexual attraction. AIMS: To assess whether a novel topical skin care product formulated with a proprietary combination of proteins, lipids, and botanical derivatives, can potentially result in a robust psycho-social-dermatological benefit via modulation epidermal oxytocin and pheromonal pathways. PATIENTS/METHODS: In this single-center prospective, randomized, controlled, double-blinded study, 40 female subjects were randomly assigned to use of either active novel skincare products, or placebos, for 4-8 weeks. Skin assessments, standardized photography, first impression ratings, and questionnaires on confidence and sexual satisfaction were conducted. RESULTS: Thirty-nine subjects completed the study and demonstrated a statistically significant improvement in skin quality following 4 and 8 weeks of use, with improvements of greater magnitude demonstrated with a longer duration of use. Product users projected a better first impression and appeared on average 3 years younger than their actual age, with 86% of subjects reporting increased confidence. Product users found random people of the opposite sex to be more attractive 88% of the time and reported improvement in sexual satisfaction in 90% of the categories. CONCLUSIONS: The use of this novel topical product culminated in statistically significant improvements in skin quality, confidence, sexual relationship satisfaction, perceived attractiveness, and youthfulness, highlighting its potential in anti-aging and mood enhancement.

RESUMO

Social scientists have given relatively scant attention to the association between attractiveness and longevity. But attractiveness may convey underlying health, and it systematically structures critical social stratification processes. We evaluated these issues using the Wisconsin Longitudinal Study (WLS, N = 8386), a survey of Wisconsin high school graduates from 1957 which provided large samples of women and men observed until their death (or through their early 80s). In doing so, we utilized a meticulously constructed measure of facial attractiveness based on the independent ratings of high-school yearbook photographs. We used linked death information from the National Death Index-plus through 2022 and Cox proportional hazard models as well as standard life-table techniques. We found that the least attractive rated sextile of the sample had significantly higher hazards of mortality (HR: 1.168, p < 0.01) compared to the middle rated four sextiles of attractiveness. This finding remained robust to the inclusion of covariates describing high-school achievement, intelligence, family background, earnings as adults, as well as mental and physical health in middle adulthood. We also found that different specifications of the attractiveness measure consistently indicated no significant differences in the mortality hazard between highly attractive and average-looking people. Using life-table techniques, we next illustrated that among women in the least attractive sextile, at age 20 their life expectancy was nearly 2 years less than others'; among men in the least attractive sextile, it was nearly 1 year less at age 20.

RESUMO

In empirical art research, understanding how viewers judge visual artworks as beautiful is often explored through the study of attributes-specific inherent characteristics or artwork features such as color, complexity, and emotional expressiveness. These attributes form the basis for subjective evaluations, including the judgment of beauty. Building on this conceptual framework, our study examines the beauty judgments of 54 Western artworks made by native Japanese and German speakers, utilizing an extreme randomized trees model-a data-driven machine learning approach-to investigate cross-cultural differences in evaluation behavior. Our analysis of 17 attributes revealed that visual harmony, color variety, valence, and complexity significantly influenced beauty judgments across both cultural cohorts. Notably, preferences for complexity diverged significantly: while the native Japanese speakers found simpler artworks as more beautiful, the native German speakers evaluated more complex artworks as more beautiful. Further cultural distinctions were observed: for the native German speakers, emotional expressiveness was a significant factor, whereas for the native Japanese speakers, attributes such as brushwork, color world, and saturation were more impactful. Our findings illuminate the nuanced role that cultural context plays in shaping aesthetic judgments and demonstrate the utility of machine learning in unravelling these complex dynamics. This research not only advances our understanding of how beauty is judged in visual art-considering self-evaluated attributes-across different cultures but also underscores the potential of machine learning to enhance our comprehension of the aesthetic evaluation of visual artworks.

RESUMO

The behavioral and neural responses to social exclusion were examined in women randomized to four conditions, varying in levels of attractiveness and friendliness. Informed by evolutionary theory, we predicted that being socially excluded by attractive unfriendly women would be more distressing than being excluded by unattractive women, irrespective of their friendliness level. Our results contradicted most of our predictions but provide important insights into women's responses to interpersonal conflict. Accounting for rejection sensitivity, P300 event-related potential amplitudes were largest when women were excluded by unattractive unfriendly women. This may be due to an expectancy violation or an annoyance with being excluded by women low on social desirability. An examination of anger rumination rates by condition suggests the latter. Only attractive women's attractiveness ratings were lowered in the unfriendly condition, indicating they were specifically punished for their exclusionary behavior. Women were more likely to select attractive women to compete against with one exception-they selected the Black attractive opponent less often than the White attractive opponent when presented as unfriendly. Finally, consistent with studies on retaliation in relation to social exclusion, women tended to rate competitors who rejected them as being more rude, more competitive, less attractive, less nice, and less happy than non-competitors. The ubiquity of social exclusion and its pointed emotional and physiological impact on women demands more research on this topic.

RESUMO

The identification of artistically creative individuals is an important matter in the fields of art, design, and psychology. One promising approach involves assessing a person's products rather than his or her personality or cognitive processes. However, the necessity of expert involvement in such evaluations is still debated. To investigate this issue, two experiments were conducted, each consisting of a production phase and an evaluation phase. In Experiment 1, participants were asked to compose a most beautiful picture, which was subsequently assessed in terms of beauty. Experiment 2 was analogous, but participants were asked to compose a most creative picture, which was then assessed in terms of creativity and beauty. The results revealed that expertise did not play a crucial role in the creation or evaluation of beauty. Both experts and non-experts largely agreed on what constitutes beauty. However, when it came to the production and assessment of creative pictures, experts had an advantage. They were the only group that was able to predict a person's creativity based on the evaluation of his or her product.

RESUMO

BACKGROUND: In an era where globalization and social media significantly reshape beauty standards, it is imperative to delve into the subjectivity of beauty and attractiveness. The lips, a key element in facial aesthetics, contribute significantly to the perception of attractiveness, and also have a profound impact on an individual's self-esteem. OBJECTIVE: To analyze the influence of ethnicity on the aesthetic preferences for lip characteristics, among male and female faces. MATERIALS AND METHODS: This study encompassed a sample of 231 study participants (153 women and 78 men) with an average age of 23.2 ±â€¯2.8 years, representing ethnicities such as African, Caucasian, Middle Eastern, and South Asian. Participants were asked to rate a series of images showcasing various lip variants, providing insights into their aesthetic preferences. RESULTS: Demographic analysis revealed gender and ethnic variations in aesthetic preferences for all the investigated lip parameters. Women were 2.42 times more likely than men to prefer no Cupid's indentation on a female model (p = 0.0019). CONCLUSIONS: The study underscores the importance of understanding cultural influences on beauty standards and challenges the notion of a universal beauty ideal. The evolving role of social media trends, such as Cupid's bow indentation elimination, raises questions about the dynamic nature of aesthetic preferences among different ethnicities.

RESUMO

The goal of the present study was to examine how body positivity and body neutrality are presented on TikTok. Based on a grounded-theory analysis, body-positivity themes included Broadly Conceptualizing Beauty (i.e., diversity in appearance types is beautiful), Body Acceptance and Love (i.e., love for and comfort in one's body), and Critiquing Standards (i.e., rejecting strict appearance standards). Body-neutrality themes included Size Inclusivity (i.e., people's activities/preferences should be based on body size), Adaptive Self-Investment (i.e., self care focused on health), Body Appreciation (i.e., respect for what one's body can do), and No Judgment (i.e., a person's worth should not be based on appearance). Further, based on a content analysis of 394 TikTok vidoes that were hashtagged with body positivity and/or body neutrality terms, at least one body-positivity theme occurred in 35.3% (n = 141) of videos, and at least one body neutrality theme occurred in 45.0% (n = 180) of videos. Body Acceptance and Love was the most common body-positivity theme, and Size Inclusivity was the most common body-neutrality theme. Understanding how TikTok videos present body positivity and neutrality is essential to further theorizing about how they might affect social media users.

RESUMO

The authors present a narrative that details the cause and process of a woman's transformation from beauty to ugliness in a Japanese tale. In " Tokaido Yotsuya Kaidan ," the metamorphosis from a beauty to an ugly woman is analyzed. After taking medication to recover from childbirth, Oiwa's face became disfigured and grotesque. Oiwa: It seems to be good for my blood, but when I drink it, it causes fraying and breakdown, causing sudden pain. I feel a numbing dullness. When she looked at herself in the mirror, she was shocked. Oiwa: What's wrong with my face? I hate this, it's such a disgusting thing. Neighbor: It was a lie that the medicine you drank was a helpful medicine that protects the appearance of people's faces. Your face is that of a wicked woman (). Oiwa: Is it really me? Why does she have the face of an evil woman? Her hair falls out in a gruesome combing scene, driving her mad. The poison Oiwa took was aconite, which grows wild in Japan. Both aconite tincture and raw aconite roots contain high concentrations of Aconitum alkaloids, which can penetrate the stratum corneum following the diffusion gradient. As her hair fell out during a horrific combing session, she abandoned her maternal role and sought revenge, having lost what she considered a symbol of her femininity. In treating female patients with facial disfigurement, it is important to be mindful of their psychological state, akin to that of Oiwa, who became disfigured through no fault of her own.

RESUMO

This study aimed to analyze images of the modern beauty of Korea during the Japanese colonial era. Searches were conducted on Google ( www.google.com ) and Naver ( www.naver.com ) for archives of newspapers and magazines that contained images of beauty. Beauty of the face and neck (the early 1920s): an article (1922) detailed the contemporary beauty standards. It specifies the desired characteristics of the eyes, nose, and mouth and dictates that "the cheeks ought to be plump enough to obscure the cheekbones" and "the neck and shoulders should also be full, concealing the collarbones." Images of beauty showing balance and proportion (the late 1920s): in 1928, a magazine article introduced the concept of "the world's beauty from a scientific perspective," which represented Western esthetics as reflected in the "Canon" of body proportions and Vitruvian Man. From the face to the body (from the late 1920s to 1930s): in 1927, a daily newspaper established the standard for global beauty. During this period, there was an increased emphasis on maintaining the body, rather than just the face, as a crucial aspect of beauty. From the mid-1930s, the concept of a "streamlined" female body shape gained popularity. Male gaze, which fragmented and objectified women's bodies, had been visualized and mass-produced. It is essential to understand how preferences have evolved and to possess skilled hands capable of improving the face and body. To properly sculpt the face and body, keen eyes and adept hands are needed.

RESUMO

Physical attractiveness profoundly affects a broad array of life experiences and outcomes, and the eyes are an important determinant of physical attractiveness. We investigated whether a particular feature of the eyes - pupil size - affects perceived attractiveness. We present competing theoretical predictions of whether dilated (larger) or constricted (smaller) pupils should appear more physically attractiveness. Youthful features tend to be attractive (i.e., neoteny), and pupil size decreases across the lifespan, so dilated (enlarged) pupils may be more attractive as a signal of youth. Alternatively, constricted (small) pupils may be more attractive because, by revealing more of the iris, they increase both color and brightness of the eyes. The present experiments demonstrate that people appear more attractive when their pupils are constricted (Experiments 1-3). This effect is equally large with black-and-white images, indicating that color per se is not necessary for the effect (Experiment 4). Rather, constricted pupils make eyes appear brighter, which in turn renders the face more attractive (Experiment 5), even when controlling for how colorful the eyes appear (Experiment 6). These results identify constricted pupils as a novel facial feature that enhances attractiveness.

RESUMO

This study sets out to investigate the potential effect of males' testosterone level on speech production and speech perception. Regarding speech production, we investigate intra- and inter-individual variation in mean fundamental frequency (fo) and formant frequencies and highlight the potential interacting effect of another hormone, i.e. cortisol. In addition, we investigate the influence of different speech materials on the relationship between testosterone and speech production. Regarding speech perception, we investigate the potential effect of individual differences in males' testosterone level on ratings of attractiveness of female voices. In the production study, data is gathered from 30 healthy adult males ranging from 19 to 27 years (mean age: 22.4, SD: 2.2) who recorded their voices and provided saliva samples at 9 am, 12 noon and 3 pm on a single day. Speech material consists of sustained vowels, counting, read speech and a free description of pictures. Biological measures comprise speakers' height, grip strength, and hormone levels (testosterone and cortisol). In the perception study, participants were asked to rate the attractiveness of female voice stimuli (sentence stimulus, same-speaker pairs) that were manipulated in three steps regarding mean fo and formant frequencies. Regarding speech production, our results show that testosterone affected mean fo (but not formants) both within and between speakers. This relationship was weakened in speakers with high cortisol levels and depended on the speech material. Regarding speech perception, we found female stimuli with higher mean fo and formants to be rated as sounding more attractive than stimuli with lower mean fo and formants. Moreover, listeners with low testosterone showed an increased sensitivity to vocal cues of female attractiveness. While our results of the production study support earlier findings of a relationship between testosterone and mean fo in males (which is mediated by cortisol), they also highlight the relevance of the speech material: The effect of testosterone was strongest in sustained vowels, potentially due to a strengthened effect of hormones on physiologically strongly influenced tasks such as sustained vowels in contrast to more free speech tasks such as a picture description. The perception study is the first to show an effect of males' testosterone level on female attractiveness ratings using voice stimuli.

RESUMO

In landscape appreciation, what tourists directly perceive is the atmosphere of the landscape. This paper introduces the concept of "Ecological Structure" from Gernot Böhme's theory of atmospheric aesthetics into the assessment of landscapes, utilizing atmosphere as a bridge between horticultural ecology, aesthetics, and culture. It examines the relationship between the objective environment and subjective perception. This study conducted a field survey of Xingqing Palace Park and selected the waterside plant landscape that directly reflects the atmosphere of the royal garden as the research object. In the first stage of this study, Scenic Beauty Estimation was used to evaluate the overall beauty of 32 landscape units; in the second stage, the Delphi method and Analytic Hierarchy Process were used to evaluate the ecological structures that affect the garden landscape atmosphere; in the third stage, the two evaluation results of the Kendall's W concord coefficient test Analytic Hierarchy Process and Scenic Beauty Estimation have high consistency, which shows that the atmosphere is great value to the beauty of the landscape. This study provides designers with a means to create a garden atmosphere using ecological structures and provides new ideas for landscape design.

RESUMO

Vocal attractiveness influences important social outcomes. While most research on the acoustic parameters that influence vocal attractiveness has focused on the possible roles of sexually dimorphic characteristics of voices, such as fundamental frequency (i.e., pitch) and formant frequencies (i.e., a correlate of body size), other work has reported that increasing vocal averageness increases attractiveness. Here we investigated the roles these three characteristics play in judgments of the attractiveness of male and female voices. In Study 1, we found that increasing vocal averageness significantly decreased distinctiveness ratings, demonstrating that participants could detect manipulations of vocal averageness in this stimulus set and using this testing paradigm. However, in Study 2, we found no evidence that increasing averageness significantly increased attractiveness ratings of voices. In Study 3, we found that fundamental frequency was negatively correlated with male vocal attractiveness and positively correlated with female vocal attractiveness. By contrast with these results for fundamental frequency, vocal attractiveness and formant frequencies were not significantly correlated. Collectively, our results suggest that averageness may not necessarily significantly increase attractiveness judgments of voices and are consistent with previous work reporting significant associations between attractiveness and voice pitch.
