Developmental Study on Leg-to-Body Ratio Preferences

Only a few studies have tested developmental differences in perception of human body attractiveness and none investigated development of Leg-to-Body Ratio (LBR) preferences. The aim of the current study was to determine whether preferences for LBR are congenital and present among children in their early childhood, or whether they are rather acquired in the course of socialization, or/and because of biological and hormonal changes. In the study participated 450 Polish people from Lower Silesia and Opole Province, whose age ranged from 3 to 20 years. They were asked to choose figurine they found the most attractive from a set of male and female figurines of various LBRs. It was found that children below 8 years of age did not prefer any particular LBR and starting from about 9 years of age, preferences towards the legs of average length emerged. Importantly, the LBR higher than the average was not perceived as the most attractive until the age of 15 years. Therefore, we have empirically confirmed that LBR preferences change during development

Human Minds and Animal Stories

The power of stories to raise our concern for animals has been postulated throughout history by countless scholars, activists, and writers, including such greats as Thomas Hardy and Leo Tolstoy. This is the first book to investigate that power and explain the psychological and cultural mechanisms behind it. It does so by presenting the results of an experimental project that involved thousands of participants, texts representing various genres and national literatures, and the cooperation of an internationally-acclaimed bestselling author. Combining psychological research with insights from animal studies, ecocriticism and other fields in the environmental humanities, the book not only provides evidence that animal stories can make us care for other species, but also shows that their effects are more complex and fascinating than we have ever thought. In this way, the book makes a groundbreaking contribution to the study of relations between literature and the nonhuman world as well as to the study of how literature changes our minds and society. "As witnessed by novels like Black Beauty and Uncle Tom’s Cabin, a good story can move public opinion on contentious social issues. In Human Minds and Animal Stories a team of specialists in psychology, biology, and literature tells how they discovered the power of narratives to shift our views about the treatment of other species. Beautifully written and based on dozens of experiments with thousands of subjects, this book will appeal to animal advocates, researchers, and general readers looking for a compelling real-life detective story." - Hal Herzog, author of Some We Love, Some We Hate, Some We Eat : Why It’s So Hard To Think Straight About Animal

Emotional Connectedness to Nature Is Meaningfully Related to Modernization. Evidence From the Meru of Kenya

The aim of this study was to investigate an affective relationship with the natural environment in a non-western society and to determine its links with modernization. Emotional connectedness to nature, a significant predictor of nature-protective behavior, was assessed in a sample of 99 members of the Meru people of Kenya, recruited in places supposedly varying regarding their level of modernization: small market towns, farming villages, and a remote pastoralist settlement in the bush. The participants answered questions concerning their level of emotional affinity toward the natural environment and their lifestyle. The results show that feelings toward the natural environment in the studied population were, in general, positive. Such findings support the universality of the Biophilia hypothesis and are promising in the light of extant literature on the links between connectedness to nature and concern for the natural environment. Surprisingly we also found that a more traditional lifestyle was negatively related to emotional connectedness to nature. These findings suggest that contact with nature under conditions of direct dependence on the natural environment may have a different influence on people’s feelings toward nature than in the west. Contrary to the common view, we conclude that the impact of modernization on non-western people’s affective relationship with nature might have been unduly demonized

The Second to Fourth Digit Ratio and Age at First Marriage in Semi-Nomadic People from Namibia

The second to fourth digit ratio (2D:4D) is used as a potential marker for prenatal androgen exposure. It is associated with many behavioral and biological variables, including fertility and sexual behavior. However, direct association between 2D:4D and reproductive success—in populations where no contraceptives are used—has not been investigated. Here, we present a study conducted among the semi-nomad Himba population living in northern Namibia. 2D:4D ratios were calculated for a sample of this population (N = 99; 60 women, 39 men), and the results were correlated with age, marital status, age at first marriage, number of children, and number of marriages. As found in the majority of previous studies, males had lower 2D:4D ratios than females. The 2D:4D ratio did not correlate with number of children. Females and males with a more masculine 2D:4D were married earlier and were more likely to have a husband or wife. We suggest that mating preferences for females with masculine 2D:4D are related to masculinity of phenotypic and personality traits of such women, which are beneficial in harsh environmental conditions and/or higher facial masculinity, which influences the perceived age of an individual. At the same time, masculine (physically strong, dominant, and hardworking) males might gather resources necessary to marry their first wife earlier

Who uses emoticons? Data from 86 702 Facebook users

Emoticons are graphical representations of emotions used in virtual communication. We explored patterns of emoticon use in a sample of 86 702 Facebook users (aged 16 to 60, 59% women).We analyzed the total number and type of emoticons posted to public Facebook feeds as a function of a user's gender, age and Big Five personality characteristics. In our sample, 90% of Facebook users employed emoticons. The most popular 15 emoticons represented 99.6% of all emoticons posted. Our results further showed that the frequency of emoticon usagewas predicted mainly by age and gender, explaining 16% of the variance, whereas user's personality scores explained b2%. These findings suggest that emoticon usage may assist in profiling user's demographic, but not necessarily psychological traits

The relationship between dark triad personality traits and sexting behaviors among adolescents and young adults across 11 countries

Background: Sexting is an increasingly common phenomenon among adolescents and young adults. Some studies have investigated the role of personality traits in different sexting behaviors within mainstream personality taxonomies like Big Five and HEXACO. However, very few studies have investigated the role of maladaptive personality factors in sexting. Therefore, the present study investigated the relationship between Dark Triad Personality Traits and experimental (i.e., sharing own sexts), risky (i.e., sexting under substance use and with strangers), and aggravated sexting (i.e., non-consensual sexting and sexting under pressure) across 11 countries. Methods: An online survey was completed by 6093 participants (Mage = 20.35; SDage = 3.63) from 11 different countries which covered four continents (Europe, Asia, Africa, and America). Participants completed the Sexting Behaviors Questionnaire and the 12-item Dark Triad Dirty Dozen scale. Results: Hierarchical regression analyses showed that sharing own sexts was positively predicted by Machiavellianism and Narcissism. Both risky and aggravated sexting were positively predicted by Machiavellianism and Psychopathy. Conclusions: The present study provided empirical evidence that different sexting behaviors were predicted by Dark Triad Personality Traits, showing a relevant role of Machiavellianism in all kinds of investigated sexting behaviors. Research, clinical, and education implications for prevention programs are discussed.WOS:000628193900001Scopus - Affiliation ID: 60105072PMID : 33806314Science Citation Index Expanded - Social Sciences Citation IndexQ1 - Q2ArticleUluslararası işbirliği ile yapılan - EVETMarch2021YÖK - 2020-2

Validation of the short version (TLS-15) of the triangular love scale (TLS-45) across 37 languages

Love is a phenomenon that occurs across the world and affects many aspects of human life, including the choice of, and process of bonding with, a romantic partner. Thus, developing a reliable and valid measure of love experiences is crucial. One of the most popular tools to quantify love is Sternberg’s 45-item Triangular Love Scale (TLS-45), which measures three love components: intimacy, passion, and commitment. However, our literature review reveals that most studies (64%) use a broad variety of shortened versions of the TLS-45. Here, aiming to achieve scientific consensus and improve the reliability, comparability, and generalizability of results across studies, we developed a short version of the scale—the TLS-15—comprised of 15 items with 5-point, rather than 9-point, response scales. In Study 1 (N = 7,332), we re-analyzed secondary data from a large-scale multinational study that validated the original TLS-45 to establish whether the scale could be truncated. In Study 2 (N = 307), we provided evidence for the three-factor structure of the TLS-15 and its reliability. Study 3 (N = 413) confirmed convergent validity and test–retest stability of the TLS-15. Study 4 (N = 60,311) presented a large-scale validation across 37 linguistic versions of the TLS-15 on a cross-cultural sample spanning every continent of the globe. The overall results provide support for the reliability, validity, and cross-cultural invariance of the TLS-15, which can be used as a measure of love components—either separately or jointly as a three-factor measure.2-s2.0-8517840985238038856Aralı

Predictors of enhancing human physical attractiveness: Data from 93 countries

People across the world and throughout history have gone to great lengths to enhance their physical appearance. Evolutionary psychologists and ethologists have largely attempted to explain this phenomenon via mating preferences and strategies. Here, we test one of the most popular evolutionary hypotheses for beauty-enhancing behaviors, drawn from mating market and parasite stress perspectives, in a large cross-cultural sample. We also test hypotheses drawn from other influential and non-mutually exclusive theoretical frameworks, from biosocial role theory to a cultural media perspective. Survey data from 93,158 human participants across 93 countries provide evidence that behaviors such as applying makeup or using other cosmetics, hair grooming, clothing style, caring for body hygiene, and exercising or following a specific diet for the specific purpose of improving ones physical attractiveness, are universal. Indeed, 99% of participants reported spending >10 min a day performing beauty-enhancing behaviors. The results largely support evolutionary hypotheses: more time was spent enhancing beauty by women (almost 4 h a day, on average) than by men (3.6 h a day), by the youngest participants (and contrary to predictions, also the oldest), by those with a relatively more severe history of infectious diseases, and by participants currently dating compared to those in established relationships. The strongest predictor of attractiveness-enhancing behaviors was social media usage. Other predictors, in order of effect size, included adhering to traditional gender roles, residing in countries with less gender equality, considering oneself as highly attractive or, conversely, highly unattractive, TV watching time, higher socioeconomic status, right-wing political beliefs, a lower level of education, and personal individualistic attitudes. This study provides novel insight into universal beauty-enhancing behaviors by unifying evolutionary theory with several other complementary perspectives.Scopus - Affiliation ID: 60105072Eylü
