Background Fruit and vegetable consumption ingestion of carotenoids have been found to be associated with human skin-color (yellowness) in a recent cross-sectional study. This carotenoid-based coloration contributes beneficially the appearance health humans is held sexually selected cue condition other species. Methodology Principal Findings Here we investigate effects fruit on longitudinally determine magnitude duration diet change required perceptibly. Diet were recorded at baseline after...
Many Labs 3 is a crowdsourced project that systematically evaluated time-of-semester effects across many participant pools. See the Wiki for table of contents files and to download manuscript.
Blood oxygenation level is associated with cardiovascular fitness, and raising oxygenated blood colouration in human faces increases perceived health. The current study used a two-alternative forced choice (2AFC) psychophysics design to quantify the colour (redness) change threshold required affect perception of facial colour, health attractiveness. Detection thresholds for judgments were lower than those attractiveness, which did not differ. results suggest redness preferences do reflect...
Judgments of leadership ability from face images predict the outcomes actual political elections and are correlated with success in corporate world. The specific facial cues that people use to judge remain unclear, however. Physical height is also associated organizational success, raising possibility contribute perceptions. Consequently, we assessed whether exist and, if so, they perception ability. We found perceived had a strong relationship Furthermore, when allowed manually manipulate...
Manipulations of voice pitch have been shown to alter attractiveness ratings, but whether preferences extend very low or high is unknown. Here, we manipulated in averaged men's and women's voices by 2 Hz intervals create a range male female speaking monopthong vowel sounds spanning frequencies from normal pitch. With these voices, used the method constant stimuli measure for voice. Nineteen university students (ages: 20–25) participated three experiments. On average, men preferred...
Sexual infidelity can be costly to members of both the extra-pair and paired couple. Thus, detecting risk is potentially adaptive if it aids in avoiding cuckoldry or loss parental relationship investment. Among men, testosterone inversely related voice pitch, offspring investment, positively pursuit short-term relationships, including sex. women, estrogen attractiveness, likelihood involvement. Although prior work has demonstrated a positive between men's levels infidelity, this study first...
Little is known about mate choice preferences outside Western, educated, industrialised, rich and democratic societies, even though these Western populations may be particularly unrepresentative of human populations. To our knowledge, this the first study to test which facial cues contribute African perceptions female attractiveness also combined role adiposity, skin colour (lightness, yellowness redness), homogeneity youthfulness in any population. Results show that youthfulness, colour,...
Body size and other signs of physical prowess are associated with leadership hierarchies in many social species. Here we (1) assess whether facial cues perceived height masculinity have different effects on judgments simulated wartime peacetime contexts (2) test how influence dominance perceptions. Results indicate that potential leaders' faces valued more a (vs. peacetime) context. Furthermore, increasing apparent increased dominance. Together, these findings suggest stature contribute to...
Using mixed design analysis of variance, this paper examines the effect body art on job applicant hireability ratings. It employs literatures social psychologies stigma and prejudice, as well aesthetic labor, to frame argument. The results indicate that photos tattooed pierced applicants result in lower ratings compared control faces. negative employment chances is, however, reduced for seeking non-customer-facing roles. In customer-facing roles, tattoo is associated with than piercing....
Recent studies suggest that judgments of facial masculinity reflect more than sexually dimorphic shape. Here, we investigated whether the perception is influenced by cues to body height and weight. We used average differences in three-dimensional face shape forty men women compute a morphological score, derived analogous measures for correlates weight based on short tall, light heavy men. found had substantial independent effects masculinity. Our findings are perceived as masculine if they...
Biologists routinely punch the flight membranes of bats to collect tissue for molecular analyses, or mark animals in field, both. The current standard is biopsy wing membrane (chiropatagium) because it easy access and less vascularized, thus bleeds less, than tail (uropatagium). Although biopsies are assumed not affect bat's ability fly capture prey, almost nothing known about wound healing times optimal size location excision. We measured 32 big brown (Eptesicus fuscus) biopsied with 2...
Facial attractiveness has a positive influence on electoral success both in experimental paradigms and the real world. One parameter that influences facial social judgements is adiposity (a correlate to body mass index, BMI). Overweight people have high are perceived be less attractive lower leadership ability. Here, we used an interactive design order assess whether most level of also as leader-like. We found participants reduced more maximize than These results indicate appearance impacts...
Several studies have examined the individual effects of facial cues to height, masculinity, and age on interpersonal interactions partner preferences. We know much less about influence these traits each other. We, therefore, how perceptions other found significant overlap. This suggests that investigating one in isolation may need account for two traits. Additionally, there is inconsistent evidence three affects dominance. investigated varying such influences dominance male faces. increases...
People often perceive themselves as more attractive and likable than others do. Here, we examined how these self-favoring biases manifest in a highly popular novel context that is particularly self-focused—selfies. Specifically, analyzed selfie-takers’ non-selfie-takers’ perceptions of their selfies versus photos taken by compared to the judgments external perceivers. Although selfie-takers non-selfie-takers reported equal levels narcissism, found perceived others’ photos, but viewed both...
Facial appearance has a well-documented effect on perceived leadership ability. Face judgments of ability predict political election outcomes across the world, and similar business CEOs company profits. Body height is also associated with ability, taller people attaining positions more than their shorter counterparts in both politics corporate world. Previous studies have found some face characteristics that are judgments, however there been no three-dimensional faces. We assessed which...
Abstract Vocal and facial masculinity are cues to underlying testosterone in men influence women’s mate preferences. Consistent with the proposal that vocal signal common information about men, prior work has revealed correlated female preferences for male masculinity. Previous studies have assessed by presenting faces voices independently using static face stimuli. By contrast, here we presented women short video clips which were simultaneously manipulated We found who preferred masculine...
Experience-dependent changes in mate choice preferences may confer an evolutionary benefit by shifting towards traits that are advantageous for specific environments. Previous studies have demonstrated prolonged exposure to one type of face biases perceptions subsequently viewed faces and body bodies. We tested whether facial adiposity were affected viewing heavy or light first assessed asking Caucasian participants (n = 59) transform three-dimensional female along a mass index (BMI)...
Using mixed design analysis of variance (ANOVA), this paper investigates the effects a subtle simulated increase in adiposity on women's employment chances service sector. Employing unique simulation altering individuals' BMIs and literature "aesthetic labour", study suggests that, especially for women, being heavier, but still within healthy BMI, deleteriously impacts hireability ratings. The explores gendered dimension prejudice by asking whether female employees at upper end BMI range are...
Recent research has demonstrated that judgments of Chief Executive Officers' (CEOs') faces predict their firms' financial performance, finding characteristics associated with higher power (e.g., dominance) greater profits. Most these studies have focused on CEOs profit-based businesses, where the main criterion for success is gain. Here, we examined whether facial appearance might measures in a sample non-profit organizations (NPOs). Indeed, contrary to findings leadership and from NPOs...
Facial appearance correlates with leadership, both in terms of who is chosen (leader selection) and how they do success). Leadership theories suggest that exceptional individuals acquire positions as leaders. Exceptional traits can differ between domains, however, so the qualities valued leaders one occupation may not match those among another. To test this, we compared relationship facial leadership across two domains: law firms mafia families. Perceptions power correlated executives...
