AbstractThe main evolutionary purpose of any living creature is to pass on its genes through reproduction, also referred to as reproductive success (Dawkins, 1976). Since successful reproduction requires the copulation of a male and a female of any given species, any sexual behavior which is not exclusively heterosexual is an enigma in evolutionary theory. The affiliation hypothesis advocates for the concept that homosexual behavior may have evolved as a way to maintain social bonds (Muscarella, 1999, 2000). It is generally accepted that sexual behavior is not dichotomous indicating that hominins would have exhibited both homosexual and heterosexual behavior (Muscarella, 2000). This theory would allow for the maintenance of social bonds but would not hinder the possibility of heterosexual reproduction. The current study tests this hypothesis using multiple measures of reproductive success and social connection.

The Influence of Body Art on Personnel SelectionDvorscak, Marissa L. (2010-03-18)Previous research on physical appearance and personnel selection suggests physical appearance significantly affects hiring decisions. With individuals dramatically changing their physical appearance with body art, such as tattoos and body piercings, this study was designed to examine the impact body art has on personnel selection and personorganization fit. Each applicant packet included a photograph of the same Caucasian male, a fabricated personal statement, with an attached resume creating three applicant packets. Application materials were identical in nature, with the exception of the photograph. The level of body art was manipulated in the photograph (Level One: pictured without visible body art, Level Two: pictured with a moderate amount of body art, and Level Three: pictured with excessive amounts of body art). Forty-five Management Professionals with Hiring Responsibilities (ranging in age from 25 years and up) and Forty-five Supervisory Professionals without Hiring Responsibilities (ranging in age from 18 years to 25 years) were asked to evaluate an applicant packet from one of the variable levels and rate the likelihood that they would be selected for an entry-level position, as well as perceived level of attractiveness. The male with no visible body art was viewed as the most attractive. The amount of visible body art did not appear to influence hiring decisions. Although age of the rater was predicted to be a potential moderator, did not moderate the effects of body art on attractiveness, person-organization fit, selection, or stereotyping.
Mass shooter bias : public perception of crime facilitates counter-stereotypic outcomesValencia, Kelsey (2020-05)Extensive research depicts a stereotypic association of aggression and criminal activity with African Americans, such as participants perceiving ambiguous behaviors as more threatening and aggressive when committed by Black targets and identifying crime-relevant objects faster when primed with Black targets (Eberhardt, Purdie, Goff, & Davies, 2004; Sinclair & Kunda, 1999). Within the past decade, there has been an increase in the number of mass shootings in America. With the rise in this violent crime, which is often perpetrated by White males, there is potentially a new association between White targets and aggression in the context of a mass shooting scenario which runs counter to the previously established stereotype linking aggression to Black perpetrators. Therefore, a study was conducted to identify whether this association between White targets and mass shootings exists and what other attributes are associated with the stereotype of mass shooters. Participants completed an online survey that asked them to rate the likelihood that motivational characteristics and personality traits were related to the criminal they read about. Subjects also rated the likelihood that males from four different racial/ethnic groups committed the individual or mass shooting they read about. Results found that White males were rated most likely to be the mass shooter and to be motivated by mental illness, hate, and social alienation. Contrary to the hypothesis, White males were also rated as being the most likely to have committed the single shooting.
Hot stuff! : the evolutionary psychology behind the attractivness of volunteer firefightersPrimavera, Nicholas J. (2019-08)Research has demonstrated a clear relationship between riskiness and reported levels of general attractiveness. Research has also explored the perceived attractiveness of altruistic behaviors of males and females. No previous study has examined if these same findings apply to members of the volunteer fire service. The current study sought to examine this question, by presenting heterosexual females with pictures and biographies of volunteer firefighters, manipulating the firefighter's riskiness and altruism to measure differences in their levels of perceived attraction. The pictures either showed the model in the traditional gear of the firefighter, the dress uniform, or plain clothes. The biography paired with these pictures either depicted a risky firefighter, an altruistic firefighter, or it simply included that they are a firefighter. Dispositional measures included personality assessment to account for potential individual differences in the relationship between these factors. In general, communal biography cues were found to be most attractive for a long-term relationship, and were rated highest on the Parenting Effort scale. Further, Risky biography cues were found to be most attractive for a brief sexual affair, and were rated highest on the Mating Effort scale
