If you’re ever engineering a nuclear power plant with a lefty, beware: apparently, the same features of their brain that make them left-handed might also make them avoid using exact numbers. Even more surprising, just having a left-handed relative makes people more prone to rounding. Maybe this is why the Romans didn’t trust them, and “sinister” comes from the Latin word for “on the left side.”
Familial Sinistrals Avoid Exact Numbers
“We report data from an internet questionnaire of sixty number trivia. Participants were asked for the number of cups in their house, the number of cities they know and 58 other quantities. We compare the answers of familial sinistrals – individuals who are left-handed themselves or have a left-handed close blood-relative – with those of pure familial dextrals – right-handed individuals who reported only having right-handed close blood-relatives. We show that familial sinistrals use rounder numbers than pure familial dextrals in the survey responses. Read More
In lieu of an explanatory blurb, we give you this Seinfeld clip.
Bystander reaction to women fighting: developing a theory of intervention.
“This article explores accounts of bystanders to female-on-female public violence. Group interviews with participants in the night-time economy are carried out. Whereas men tend to respond to the discussion topic of female-on-female violence with laughter, this laughter reveals ambivalence and discomfort as much as amusement. Men seem to negotiate the tension between the expectation that they should intervene in emergencies and a catalogue of costs that attend intervention. Read More
In this study, the researchers found that being traditionally masculine was correlated with energy drink use. Surprisingly, though, being a jock or frat guy actually weakened this effect. Wondering how “masculinity” is scientifically measured? Why, using the Conformity to Masculine Norms Inventory, of course! It includes the following categories: Emotional Control, Risk-Taking, Violence, Dominance, Self-Reliance, Primacy of Work, Power Over Women, Disdain for Homosexuals, Pursuit of Status, Playboy, and (… wait for it …) WINNING!
Energy Drink Use and Its Relationship to Masculinity, Jock Identity, and Fraternity Membership Among Men.
The present study examined whether previous findings linking masculinity constructs and health behaviors applied to a relatively recent health risk behavior for men, the consumption of energy drinks. In addition, it also examined whether self-identifying as a jock and being a member of a fraternity would moderate the relationships between masculinity constructs and energy drink consumption.

When I was in college, there were three drinking games: beer pong, flip cup, and quarters. Apparently, there are now 100 distinct drinking games, including one called (unimaginatively) “Let’s get fucked up”. Although the point of all of them is, obviously, to get drunk, these scientists set out to see if there are differences between them, including how many drinks are drunk by the drunk participants while drinking.
Are they all the same? An exploratory, categorical analysis of drinking game types.
Drinking games have become a ubiquitous part of the college student drinking culture and are associated with drinking to intoxication and increased alcohol consequences. Contemporary research commonly considers drinking games holistically, with little to no consideration to the different drinking game types. The current study describes the creation of a novel DG categorization scheme and reports differences between DG categories. Read More
“When creating an artwork, the artist makes a decision regarding the orientation at which the work is to be hung based on their aesthetic judgement and the message conveyed by the piece. Is the impact or aesthetic appeal of a work diminished when it is hung at an incorrect orientation? Read More
Health care associated infections are serious problems for today’s medical community. It is generally assumed that health care workers come in contact with pathologic bacteria and unwittingly transfer them to patients either directly with their hands, or indirectly through some inanimate object. If a doctor washes his or her hands before seeing a patient and then touches a colonized object, the benefit of hand washing may have been undone. Previous studies have identified stethoscopes, neck ties, mobile phones, keyboards, lab coats, and other commonly worn accessories as potential sources of disease transmission contributing to health care associated infections. Women doctors’ purses have not previously been studied as a potential source of disease transmission. This study evaluated whether doctors’ purses served as a potential source of disease transmission. Read More
“Consequential political judgments often rely on facial appearance, yet the facial cues that compel such judgments remain unspecified. We predicted that judgments of political party affiliation, and by extension their accuracy, rely on the sex-typicality of facial cues (i.e., the degree of facial masculinity and femininity). In Study 1, we found that among Republicans/Conservatives in the 111th U.S. House of Representatives, women were significantly more sex-typical than men. This was not true for Democrats/Liberals.

“Cell phones have become important communication media for individuals in romantic relationships. The frequency of and methods used for communication may vary by adults’ style of romantic attachment. Female university students (N = 31) currently in romantic relationships responded to a questionnaire. They estimated the frequency of calls and text messages received from and made to their romantic partners and completed the Experiences in Close Relationships-Revised instrument, a measure of attachment anxiety and avoidance. Also, the participants reviewed their cell phones’ memories and provided accurate frequency of communication to and from the romantic partner. Read More
“Para-social behavior is a form of quasi-interpersonal behavior that results when audience members develop bonds with media personalities that can resemble interpersonal social interaction, but is not usually applied to political communication. This study tested whether the “Drinking-Buddy” Scale, a simple question frequently used in political communication, could be interpreted as a single-item measure of para-social behavior with respect to political candidates in terms of image judgments related to interpersonal attraction and perceived similarity to self.

“Sex and disgust are basic, evolutionary relevant functions that are often construed as paradoxical. In general the stimuli involved in sexual encounters are, at least out of context strongly perceived to hold high disgust qualities. Saliva, sweat, semen and body odours are among the strongest disgust elicitors. This results in the intriguing question of how people succeed in having pleasurable sex at all. One possible explanation could be that sexual engagement temporarily reduces the disgust eliciting properties of particular stimuli or that sexual engagement might weaken the hesitation to actually approach these stimuli.
Participants were healthy women (n = 90) randomly allocated to one of three groups: the sexual arousal, the non-sexual positive arousal, or the neutral control group. Film clips were used to elicit the relevant mood state. Participants engaged in 16 behavioural tasks, involving sex related (e.g., lubricate the vibrator) and non-sex related (e.g., take a sip of juice with a large insect in the cup) stimuli, to measure the impact of sexual arousal on feelings of disgust and actual avoidance behaviour.
