NCBI ROFL: Study shows reading Twilight makes you more vampiric.
Becoming a vampire without being bitten: the narrative collective-assimilation hypothesis.
“We propose the narrative collective-assimilation hypothesis—that experiencing a narrative leads one to psychologically become a part of the collective described within the narrative. In a test of this hypothesis, participants read passages from either a book about wizards (from the Harry Potter series) or a book about vampires (from the Twilight series). Both implicit and explicit measures revealed that participants who read about wizards psychologically became wizards, whereas those who read about vampires psychologically became vampires. The results also suggested that narrative collective assimilation is psychologically meaningful and relates to the basic human need for connection. Specifically, the tendency to fulfill belongingness needs through group affiliation moderated the extent to which narrative collective assimilation occurred, and narrative collective assimilation led to increases in life satisfaction and positive mood, two primary outcomes of belonging. The implications for the importance of narratives, the need to belong to groups, and social surrogacy are discussed.”

NCBI ROFL: Do women with urinary incontinence really know where all the toilets are? The toilet paper.
“AIMS OF STUDY: Aim of this study was to determine if women with overactive bladder really do have a more detailed knowledge about toilets and their conditions in their vicinity in comparison to women with urinary stress incontinence and those without any urinary symptoms. PATIENTS AND METHODS: A questionnaire survey of 270 women from three symptom groups, those with stress incontinence, overactive bladder and controls without any bladder symptoms from an inner city area and two local towns. The knowledge of the three groups was compared and measured by a score assessed by the authors who had visited the toilets themselves. RESULTS: Women with overactive bladder are more likely to exhibit precautionary voiding prior to leaving home and have significantly more detailed knowledge about toilets in their neighbourhood. DISCUSSION: The overactive bladder seems to have a greater influence on behaviour and on quality of life than stress incontinence which could mean that they are more tortured by their symptoms.”

It’s Facebook week on NCBI ROFL! All this week we’ll be featuring papers about everyone’s favorite social networking site. Enjoy!
Men Are from Mars, Women Are from Venus? Examining Gender Differences in Self-Presentation on Social Networking Sites.
“Psychological research on gender differences in self-presentation has already revealed that women place higher priority on creating a positive self-presentation, while men are less concerned about the image they present in face-to-face (ftf) communication. Nowadays, with the extensive use of new media, self-presentation is no longer so closely tied to ftf situations, but can also take place in the online world. Specifically, social networking sites (SNS), such as Facebook or MySpace, offer various features such as profile pictures, groups, and virtual bulletin boards with which users can create elaborated online representations of themselves. What remains open is whether this virtual self-presentation on SNS is subject to gender differences. Based on studies emphasizing gender-related differences in Internet communication and behavior in general, it can be assumed that men and women have different motives regarding their SNS usage as well. A multimethodological study, combining results of an online survey and a content analysis of 106 user profiles, assessed users’ diverse motives ...

NCBI ROFL: Does it take one to know one? Endorsement of conspiracy theories is influenced by personal willingness to conspire.
“We advance a new account of why people endorse conspiracy theories, arguing that individuals use the social-cognitive tool of projection when making social judgements about others. In two studies, we found that individuals were more likely to endorse conspiracy theories if they thought they would be willing, personally, to participate in the alleged conspiracies. Study 1 established an association between conspiracy beliefs and personal willingness to conspire, which fully mediated a relationship between Machiavellianism and conspiracy beliefs. In Study 2, participants primed with their own morality were less inclined than controls to endorse conspiracy theories – a finding fully mediated by personal willingness to conspire. These results suggest that some people think ‘they conspired’ because they think ‘I would conspire’.”

NCBI ROFL: The best men are (not always) already taken: female preference for single versus attached males depends on conception risk.
“Because men of higher genetic quality tend to be poorer partners and parents than men of lower genetic quality, women may profit from securing a stable investment from the latter, while obtaining good genes via extrapair mating with the former. Only if conception occurs, however, do the evolutionary benefits of such a strategy overcome its costs. Accordingly, we predicted that (a) partnered women should prefer attached men, because such men are more likely than single men to have pair-bonding qualities, and hence to be good replacement partners, and (b) this inclination should reverse when fertility rises, because attached men are less available for impromptu sex than single men. In this study, 208 women rated the attractiveness of men described as single or attached. As predicted, partnered women favored attached men at the low-fertility phases of the menstrual cycle, but preferred single men (if masculine, i.e., advertising good genetic quality) when conception risk was high.”

NCBI ROFL: [Ring ring] … Hello? … Hi! Are you a lesbian?
A brief telephone interview to identify lesbian and bisexual women in random digit dialing sampling.
“Lesbian health research has most often relied on nonprobability samples that are biased and restrict generalizability. Random sampling could reduce bias, but requires development of a method for fast and reliable screening of a large number of women. We tested the feasibility of using a brief telephone interview to assess sexual attraction, behavior, and identity. Using Random Digit Dialing in a neighborhood of Boston with a high density of lesbian residents, we interviewed 202 women aged 18 to 59. Of the respondents, 33% reported some sexual attraction to other women, 20% reported sex with women since age 18, and 14% identified as a lesbian. The high level of cooperation with the study among eligible women (94%) and the high proportion of women who disclosed homosexual attraction, behavior, or identity show that it is feasible to use a brief screening questionnaire about sexuality of women over the telephone even without building special rapport with the respondents.”

NCBI ROFL: Study proves guns make you an a**hole.
“We tested whether interacting with a gun increased testosterone levels and later aggressive behavior. Thirty male college students provided a saliva sample (for testosterone assay), interacted with either a gun or a children’s toy for 15 min, and then provided another saliva sample. Next, subjects added as much hot sauce as they wanted to a cup of water they believed another subject would have to drink. Males who interacted with the gun showed significantly greater increases in testosterone and added more hot sauce to the water than did those who interacted with the children’s toy. Moreover, increases in testosterone partially mediated the effects of interacting with the gun on this aggressive behavior.”

NCBI ROFL: Immunizing against prejudice: effects of disease protection on attitudes toward out-groups.
“Contemporary interpersonal biases are partially derived from psychological mechanisms that evolved to protect people against the threat of contagious disease. This behavioral immune system effectively promotes disease avoidance but also results in an overgeneralized prejudice toward people who are not legitimate carriers of disease. In three studies, we tested whether experiences with two modern forms of disease protection (vaccination and hand washing) attenuate the relationship between concerns about disease and prejudice against out-groups. Study 1 demonstrated that when threatened with disease, vaccinated participants exhibited less prejudice toward immigrants than unvaccinated participants did. In Study 2, we found that framing vaccination messages in terms of immunity eliminated the relationship between chronic germ aversion and prejudice. In Study 3, we directly manipulated participants’ protection from disease by having some participants wash their hands and found that this intervention significantly influenced participants’ perceptions of out-group members. Our research suggests that public-health interventions can benefit society in areas beyond immediate health-related domains by informing novel, modern remedies for prejudice.”

NCBI ROFL: Living large: The powerful overestimate their own height.
“In three experiments, we tested the prediction that individuals’ experience of power influences their perceptions of their own height. High power, relative to low power, was associated with smaller estimates of a pole’s height relative to the self (Experiment 1), with larger estimates of one’s own height (Experiment 2), and with choice of a taller avatar to represent the self in a second-life game (Experiment 3). These results emerged regardless of whether power was experientially primed (Experiments 1 and 3) or manipulated through assigned roles (Experiment 2). Although a great deal of research has shown that more physically imposing individuals are more likely to acquire power, this work is the first to show that powerful people feel taller than they are. The discussion considers the implications for existing and future research on the physical experience of power.”

NCBI ROFL: The cutest little baby face: a hormonal link to sensitivity to cuteness in infant faces.
“We used computer image manipulation to develop a test of perception of subtle gradations in cuteness between infant faces. We found that young women (19-26 years old) were more sensitive to differences in infant cuteness than were men (19-26 and 53-60 years old). Women aged 45 to 51 years performed at the level of the young women, whereas cuteness sensitivity in women aged 53 to 60 years was not different from that of men (19-26 and 53-60 years old). Because average age at menopause is 51 years in Britain, these findings suggest the possible involvement of reproductive hormones in cuteness sensitivity. Therefore, we compared cuteness discrimination in pre- and postmenopausal women matched for age and in women taking and not taking oral contraceptives (progestogen and estrogen). Premenopausal women and young women taking oral contraceptives (which raise hormone levels artificially) were more sensitive to variations of cuteness than their respective comparison groups. We suggest that cuteness sensitivity is modulated by female reproductive hormones.”

NCBI ROFL: Aggression-inhibiting influence of sexual humor.
“Forty-eight undergraduate males participated in an experiment designed to investigate the hypothesis that prior exposure to sexual humor would reduce the level of aggression directed by angry individuals against the person who had previously provoked them. In order to examine this suggestion, subjects were first angered or not angered by a male confederate; next, exposed to either neutral, nonhumorous pictures or to one of two types of sexual humor (nonexploitative, exploitative); and finally, provided with an opportunity to aggress against this individual by means of electric shock. Results indicated that exposure to exploitative sexual humor, but not exposure to nonexploitative sexual humor, significantly reduced the strength of subjects’ later attacks against the victim. These findings are discussed in terms of the results of a follow-up study suggesting that individuals are more likely to think or fantasize about exploitative than nonexploitative sexual humor following the removal of such stimuli.”

NCBI ROFL: Salivary testosterone levels in men at a U.S. sex club.
“Vertebrate males commonly experience elevations in testosterone levels in response to sexual stimuli, such as presentation of a novel mating partner. Some previous human studies have shown that watching erotic movies increases testosterone levels in males although studies measuring testosterone changes during actual sexual intercourse or masturbation have yielded mixed results. Small sample sizes, “unnatural” lab-based settings, and invasive techniques may help account for mixed human findings. Here, we investigated salivary testosterone levels in men watching (n = 26) versus participating (n = 18) in sexual activity at a large U.S. sex club. The present study entailed minimally invasive sample collection (measuring testosterone in saliva), a naturalistic setting, and a larger number of subjects than previous work to test three hypotheses related to men’s testosterone responses to sexual stimuli. Subjects averaged 40 years of age and participated between 11:00 pm and 2:10 am. Consistent with expectations, results revealed that testosterone levels increased 36% among men during a visit to the sex club, with the magnitude of testosterone change significantly greater among participants (72%) compared with observers (11%). Contrary to expectation, men’s testosterone changes were unrelated to their age. These findings were generally consistent with vertebrate studies indicating elevated male testosterone in response to sexual stimuli, but also point out the importance of study context since participation in sexual behavior had a stronger effect on testosterone increases in this study but unlike some previous human lab-based studies.”

NCBI ROFL: How to make pooping babies more appealing.
When Pooping Babies Become More Appealing: The Effects of Nonconscious Goal Pursuit on Experienced Emotions.
“In this report, we argue that the intensity of the emotions people experience is partly determined by the goals they nonconsciously pursue, and that this effect is functional in nature: Emotions are modulated in ways that may increase the probability of goal achievement. To test this hypothesis, we primed female participants with a motherhood goal and then measured their level of disgust in response to mildly disgusting pictures. Priming led to a reduction of disgust in response to goal-relevant stimuli (e.g., pictures of babies with runny noses) but not goal-irrelevant stimuli. This effect was moderated by the women’s probability of conception, a proxy of their ability to pursue the motherhood goal.”

NCBI ROFL: And the And the October “no sh*t, Sherlock” award goes to…
Beautiful faces have variable reward value: fMRI and behavioral evidence.
“The brain circuitry processing rewarding and aversive stimuli is hypothesized to be at the core of motivated behavior. In this study, discrete categories of beautiful faces are shown to have differing reward values and to differentially activate reward circuitry in human subjects. In particular, young heterosexual males rate pictures of beautiful males and females as attractive, but exert effort via a keypress procedure only to view pictures of attractive females. Functional magnetic resonance imaging at 3 T shows that passive viewing of beautiful female faces activates reward circuitry, in particular the nucleus accumbens. An extended set of subcortical and paralimbic reward regions also appear to follow aspects of the keypress rather than the rating procedures, suggesting that reward circuitry function does not include aesthetic assessment.”

NCBI ROFL: Why women apologize more than men.
Why women apologize more than men: gender differences in thresholds for perceiving offensive behavior.
“Introduction: “Despite wide acceptance of the stereotype that women apologize more readily than men, there is little systematic evidence to support this stereotype or its supposed bases (e.g., men’s fragile egos). We designed two studies to examine whether gender differences in apology behavior exist and, if so, why. In Study 1, participants reported in daily diaries all offenses they committed or experienced and whether an apology had been offered. Women reported offering more apologies than men, but they also reported committing more offenses. There was no gender difference in the proportion of offenses that prompted apologies. This finding suggests that men apologize less frequently than women because they have a higher threshold for what constitutes offensive behavior. In Study 2, we tested this threshold hypothesis by asking participants to evaluate both imaginary and recalled offenses. As predicted, men rated the offenses as less severe than women did. These different ratings of severity predicted both judgments of whether an apology was deserved and actual apology behavior.”

NCBI ROFL: Dirty liberals! Reminders of physical cleanliness influence moral and political attitudes.
“Many moral codes place a special emphasis on bodily purity, and manipulations that directly target bodily purity have been shown to influence a variety of moral judgments. Across two studies, we demonstrated that reminders of physical purity influence specific moral judgments regarding behaviors in the sexual domain as well as broad political attitudes. In Study 1, individuals in a public setting who were given a reminder of physical cleansing reported being more politically conservative than did individuals who were not given such a reminder. In Study 2, individuals reminded of physical cleansing in the laboratory demonstrated harsher moral judgments toward violations of sexual purity and were more likely to report being politically conservative than control participants. Together, these experiments provide further evidence of a deep link between physical purity and moral judgment, and they offer preliminary evidence that manipulations of physical purity can influence general (and putatively stable) political attitudes.”

“Previous studies indicated various nonverbal behaviors including eye contact of women are associated with men’s approach; however, duration of the eye contact was not tested. In Exp. 1, a female confederate established eye-contact of 3 sec. or 1 sec. with a man when entering a bar. Duration of returned glance was the dependent variable. Analysis showed mean duration of the return glance was statistically shorter in the 1-sec. condition. In Exp. 2, the confederate made eye contact with a man and looked at him less than 1 sec., 2 sec., or 4 sec. The presence versus absence of smile was the dependent variable. Longer duration of eye contact was associated with an increase of smiling.”

NCBI ROFL: Social perceptions of individuals missing upper front teeth.
“Although it is assumed that there are negative social consequences for individuals missing visible front teeth, no study of the way in which edentulous individuals were perceived in a social context and the potential social repercussions could be located. This initial study concerned college students’ perceptions of individuals missing visible upper front teeth. 200 volunteers, 19 to 50 years of age (M = 20.6, SD = 4.4), rated five photographs depicting tooth presence or absence, from a full dentition to missing as many as four upper front teeth, on social traits including attractiveness, health status, educational attainment, satisfaction with life, active social life, aggressiveness, intelligence, trustworthiness, amount of caring, friendship, dating, and likelihood to live as a neighbor. Analysis suggested a person missing visible teeth was more negatively perceived on all social traits than a person with full dentition. Results were strongest when students were proposed to be linked to the edentulous individual in a personal way, i.e., dating or living as neighbor. Men and women agreed on perceptions of social traits and dentition condition. These results suggest the presence of strong Western cultural values, whereby those who are missing teeth may experience significant barriers to personal and social success.”

Self-perceived technical orientation and attitudes toward being flattered.
“An investigation was done of the relationship between scores on the Technical Orientation Scale and self-ratings of liking to be flattered among 103 working adults. As hypothesized, scores for technical orientation were negatively correlated with two self-report measures of liking to be flattered. Women had a significantly stronger rating for liking to be flattered. We conclude that a technical orientation may be a moderator variable for the potential of liking to be flattered.”

“The present study investigated the contribution of men’s facial hair to impression formation. Participants evaluated photographs of one of four versions of a man–clean shaven, mustached, goateed, or bearded–on a 7-point scale. In Study 1, participants were 106 Brazilian undergraduates (68 men and 38 women). Beardedness was associated with older age, greater responsibility, and leftist political ideas. In Study 2, respondents were 50 Brazilian personnel managers (28 men and 22 women) who made hiring decisions at different companies in the city of Saõ Paulo. Personnel managers clearly preferred clean shaven over bearded, mustached, or goateed men as prospective employees. In a hiring situation for a conservative occupation, a man who signals disposition to conform to rules may be preferred by personnel managers over another who signals nonconformity.”
