When it comes to the heated subject of differences between how men and women behave, debate in psychology has centered on mate preferences and general interests. The available research shows that when it comes to (heterosexual) mating preferences, men are relatively more interested in physical beauty, while women are relatively more interested in earning capacity. As for general interests, men are more interested in physical things, while women are more interested in people.
Even the staunchest evolutionary psychologists would acknowledge these are partially overlapping bell curves: There are plenty of men who are fascinated by other people, and plenty of women looking for physical beauty in a partner above all else. Yet the findings have been met with fierce resistance in some quarters. One of the more sophisticated rejoinders is known as social roles theory: The differences do exist, but they’re entirely or largely the result of gender roles imposed by society on individuals. However, a new study released as a preprint at PsyArXiv and involving participants from 36 countries has failed to replicate a key finding that’s previously been cited in support of social roles theory.
A new survey of beliefs held by social psychologists (335 mostly US-based members of the Society of Experimental Social Psychology) has confirmed previous reports that the field is overwhelmingly populated by researchers of a left-wing, liberal bent. What’s more, David Buss and William von Hippel – the evolutionary social psychologists who conducted and analysed the survey – say their findings, published open-access in Archives of Scientific Psychology, suggest that some social psychologists may be opposed, for ideological reasons, to insights rooted in evolutionary psychology.
Buss and von Hippel add that compounding matters is an irony – the desire of some researchers to signal their ideological stance and commitment to others who share their political views, which is a manifestation of the evolved human adaptation to form coalitions. “Part of this virtue signalling entails rejecting a caricature of evolutionary psychology that no scientist actually holds,” they write.
Schadenfreude – which literally means “harm-joy” in German –is the sense of pleasure derived from others’ misfortune. It’s a “poorly understood” emotion, according to a group of psychologists at Emory University in the US, and in their review paper in New Ideas in Psychology they propose a new “tripartite” model of schadenfreude based on the idea that deep-seated survival concerns can motivate us to see others as less than human.
Towards the end of the Disney film Aladdin, our hero’s love rival, the evil Jafar, discovers Aladdin’s secret identity and steals his magic lamp. Jafar’s wish to become the world’s most powerful sorcerer is soon granted and he then uses his powers to banish Aladdin to the ends of the Earth.
What follows next is a lingering, close-up of Jafar’s body. He leans forward, fists clenched, with an almost constipated look on his face. He then explodes in uncontrollable cackles that echo across the landscape. For many millennials growing up in the 1990s, it is an archetypical evil laugh.
A recent essay by Jens Kjeldgaard-Christiansen in the Journal of Popular Culture asks what the psychology behind this might be. Kjeldgaard-Christiansen is well placed to provide an answer having previously used evolutionary psychology to explain the behaviours of heroes and villains in fiction more generally.
Shame feels so awful it’s hard to see how it could have an upside, especially when you consider specific triggers of the emotion – such as body-shaming, which involves criticising someone for how their body looks. But is shame always an ugly emotion that we should try to do away with? Or can it be helpful?
The answer, according to a new study published in PNAS of 899 people from all over the world is that, as an emotion, shame can not only be useful but is fundamental to our ability to survive and thrive in a group. The essential job of shame, it seems, is to stop us from being too selfish for our own good.
The effect of playing sport on men’s testosterone levels is well documented. Generally speaking, the winner enjoys a testosterone boost, while the loser experiences the opposite (though far less studied, competition unsurprisingly also affects women’s hormonal levels, though not in the same ways as men’s). The evolutionary-based explanation for the hormonal effects seen in men is that the winner’s testosterone rise acts to increase their aggression and the likelihood that they will seek out more contests, while the loser skulks off to lick their wounds. When it comes to vicarious effects of competition on men’s testosterone, however, the findings are more mixed. There’s some evidence that male sports fans show testosterone gains after seeing their teams win, but other studies have failed to replicate this finding.
A new, small study in Human Nature adds to this literature by examining the hormonal changes (testosterone and cortisol) in fathers watching their children play a football game – a situation in which you might particularly expect to see vicarious hormonal effects since it’s the men’s own kin who are involved.
Alongside the physical jostle, thrust and tug of sport there is a parallel contest involving words. Although this trash talking between players before, during and after games is well known, it is surprisingly unstudied by psychologists. Yet these exchanges play a major role, arguably swinging the outcome of games. Consider an infamous example: the 2006 football world cup final in which Italy’s Marco Materazzi insulted the sister or mother (depending on whose account you believe) of France’s star player Zinadine Zidane, who in turn responded by head butting Materazzi. Zidane was then sent off, with Italy going on to win the game on penalties.
Is trash talking more prevalent in some sports than others? What does trash talk tend to be about? A new exploratory paper in Human Nature is among the first systematic investigations of trash talking in sport, and certainly the first to examine the phenomenon through an evolutionary lens.
Many animals, including sea lions and dogs, can accurately predict the size and strength of a potential adversary in part by listening to their vocalisations – such as the ferocity and depth of their barks or growls. People weren’t thought to be much good at doing something similar. But in previous studies, volunteers were asked to judge the absolute height and strength of another person, based on the sound of an aggressively-spoken sentence or a ‘roar’. Now in a new study, published in iScience, when participants were instead instructed to listen to recordings and judge how much stronger, or weaker, taller or shorter the vocaliser was, compared with themselves, they could do this with a high degree of accuracy.
As the researchers, led by David Reby at the University of Sussex, point out, this is potentially far more practically useful than being able to discern someone else’s absolute height or strength.
Celebrities are people famous for being famous. Have you ever given any thought to how it happens that pop-culture figures become so well-known, even when they have risen to the top upon a wave of interest for which there was not the slightest rational explanation? What is the real root cause of our lemming-like rush to keep tabs on insignificant but famous people? What leads us to share this information on social media? Why do we visit gossip portals and read tabloids, even though they’re totally worthless to us? Partial answers to these questions are given by a trio of researchers via a series of creative experiments that they’ve reported in Psychology of Popular Media Culture.
In 1914, the psychologist Leta Hollingworth’s experiments punctured holes in the prevailing idea that menstruating affects women’s intellect. But a century on, the ovulation cycle continues to interest psychologists, who today focus on how it affects sexual behaviour. A popular evolutionary psychology theory states that during fertile periods, women become more interested in men who use dominant masculine behaviour, as this signals they are likely to provide good genes for any offspring. A University of Goettingen team have now conducted the largest ever test of this idea, published as a pre-print at PsyArxiv.
