Gift Giving at Israeli Weddings as a Function of Genetic Relatedness and Kinship Certainty

This study examines gift giving at Israeli weddings. In accordance with kin selection theory, we hypothesized that wedding guests possessing greater genetic relatedness to the newlyweds would offer greater sums of money as wedding gifts. We also hypothesized that family members stemming from the maternal side (where the genetic lineage has higher kinship certainty), would offer the newlyweds more money than those stemming from the paternal side. Data on the monetary gift sums of the wedding guests from 30 weddings were collapsed according to two criteria: (1) genetic relatedness (0%, 6.25%, 12.5%, 25%, and 50%) and (2) kinship certainty (maternal or paternal lineage). Both hypotheses were supported. We discuss the implications of these data in understanding family dynamics, as well as practical applications associated with the marketing of gifts

“I like them, but won't ‘like’ them”: An examination of impression management associated with visible political party affiliation on Facebook

Unlike traditional media, our interactions with political parties via social media are generally public, subject to scrutiny by others and, consequently, a self-presentation concern. This paper contributes to theory on impression management within social network sites (SNSs) by providing an understanding of the effect of visible affiliation on page ‘Liking’ behavior in the context of political parties; specifically, the possible association with social anxiety and the use of protective impression management. We predict that while users may be motivated to ‘Like’ a political party, some may feel socially anxious about the impressions their friends may derive from this action, and so ultimately choose to refrain from ‘Liking’ the party. Furthermore, we propose a new function of ‘Secret Likes’ (i.e. ‘Likes’ that others cannot see) as a means to increase gateway interactions. A survey of eligible voters (n=225) was conducted in the month prior to the 2015 UK general election, examining behavior associated with the Facebook pages of the two largest political parties. Results support that conspicuous affiliation with political parties indeed hinders intention to ‘Like’ political pages and is associated with social anxiety. ‘Secret Likes’ were found to be a successful method to increase gateway interactions. In addition to the theoretical contribution, implications for political party communications and site designers are considered

Developmental and evolutionary assumptions in a study about the impact of premature birth and low income on mother–infant interaction

In order to study the impact of premature birth and low income on mother–infant interaction, four Portuguese samples were gathered: full-term, middle-class (n=99); premature, middle-class (n=63); full-term, low income (n=22); and premature, low income (n=21). Infants were filmed in a free play situation with their mothers, and the results were scored using the CARE Index. By means of multinomial regression analysis, social economic status (SES) was found to be the best predictor of maternal sensitivity and infant cooperative behavior within a set of medical and social factors. Contrary to the expectations of the cumulative risk perspective, two factors of risk (premature birth together with low SES) were as negative for mother–infant interaction as low SES solely. In this study, as previous studies have shown, maternal sensitivity and infant cooperative behavior were highly correlated, as was maternal control with infant compliance. Our results further indicate that, when maternal lack of responsiveness is high, the infant displays passive behavior, whereas when the maternal lack of responsiveness is medium, the infant displays difficult behavior. Indeed, our findings suggest that, in these cases, the link between types of maternal and infant interactive behavior is more dependent on the degree of maternal lack of responsiveness than it is on birth status or SES. The results will be discussed under a developmental and evolutionary reasonin

A cross cultural study of gender differences in omnichannel retailing contexts

This research examines gender difference in omnichannel experience in modern shopping malls, combining personal, physical and virtual encounters. It proposes a new theoretical model: the gender-based shopping mall omnichannel experience model. Data was collected using 1139 questionnaires completed by millennial shoppers in the United Kingdom and United Arab Emirates. Data was analysed using partial least squares. The results showed a shift in males shopping behaviour as they pay more attention to peer interaction on social platforms, service excellence, convenience, diversity and personalisation in shopping malls than female shoppers, while aesthetics and privacy are more important for female shoppers

Narcissism and the strategic pursuit of short-term mating : universal links across 11 world regions of the International Sexuality Description Project-2.

Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responses from a cross-cultural survey of 30,470 people across 53 nations spanning 11 world regions (North America, Central/South America, Northern Europe, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, Southeast Asia, and East Asia) were used to evaluate whether narcissism (as measured by the Narcissistic Personality Inventory; NPI) was universally associated with short-term mating. Results revealed narcissism scores (including two broad factors and seven traditional facets as measured by the NPI) were functionally equivalent across cultures, reliably associating with key sexual outcomes (e.g., more active pursuit of short-term mating, intimate partner violence, and sexual aggression) and sex-related personality traits (e.g., higher extraversion and openness to experience). Whereas some features of personality (e.g., subjective well-being) were universally associated with socially adaptive facets of Narcissism (e.g., self-sufficiency), most indicators of short-term mating (e.g., unrestricted sociosexuality and marital infidelity) were universally associated with the socially maladaptive facets of narcissism (e.g., exploitativeness). Discussion addresses limitations of these cross-culturally universal findings and presents suggestions for future research into revealing the precise psychological features of narcissism that facilitate the strategic pursuit of short-term mating

En este estudio se han usado respuestas de la encuesta transcultural de 30.470 personas de 53 naciones de 11 regiones mundiales (América del Norte, América del Sur/América Central, Europa del Norte, Europa del Oeste, Europa del Este, Europa del Sur, Oriente Próximo, África, Asia del Sur/Sudoeste de Asia, Asia del Este y Oceanía) para evaluar si el narcisismo (medido por el Inventario de Personalidad Narcisista; NPI) se asocia panuniversalmente con los indicadores del emparejamiento a corto plazo, tanto en la dirección, como en la intensidad. Los resultados sugieren que el narcisismo (incluidos muchos aspectos suyos medidos por el NPI) tiene las mismas asociaciones básicas con los rasgos de personalidad relacionados con el sexo (p. ej. extraversión alta) y con los resultados sexuales claves (p. ej. búsqueda más activa de las estrategias del emparejamiento a corto plazo) a través de las 11 mayores regiones mundiales del PDSI 2. La discusión se enfoca en las implicaciones y limitaciones del estudio actual

The Terminal Investment Hypothesis and Age-related Differences in Female Preference for Dads vs. Cads

Williams ' (1966) terminal investment hypothesis states that in species showing an age-related decline in reproductive value, reproductive effort should increase with age. Non-human primate studies have supported this hypothesis, though research in humans is lacking, likely due to the restricted age range of participants in typical studies in evolutionary psychology. We hypothesize that older women will decrease mating effort in order to allocate additional resources to parental effort, and that this shift will be manifested in women's' mate selection preferences. Because older women are hypothesized to shift resources from mating to parenting, they may show greater preferences for partners with high potential for paternal investment compared to partners with features signaling high potential for genetic investment. We use character sketches of "dad" and "cad" male reproductive strategies to demonstrate the age-related shift in relationship preferences. We found that older women prefer mating strategies that are related with higher paternal investment. In addition, we found that a woman's selfdescription changes with age, mediating the age-related changes in mate preferences. We suggest that these changes serve the changing needs of an older woman and the transition from investing in future offspring to investment in the current offspring
