Stereotype threat is one of those social psychology concepts that has managed to break out of the academic world and into everyday conversation: the idea that a fear of conforming to stereotypes – for example, that girls struggle at maths – can make those stereotypes self-fulfilling, thanks to the adverse effect of anxiety and excessive self-consciousness on performance.
A recent review suggested that stereotype threat has a robust but small-to-medium sized effect on performance, but a meta-analysis suggests that publication bias may be a problem in this literature, inflating the apparent size of the effect. Also, the majority of the work has been done under laboratory conditions, which may not reflect what happens in the wider world. So when a field study comes along, it’s worth paying attention to, and a paper published as a pre-print at PsyArXiv from Tom Stafford at the University of Sheffield looks at a domain involving high pressure, clear success criteria, and a presupposition that’s it’s more a guy thing: chess.
There are behavioural differences, on average, between the sexes – few would dispute that. Where the debate rages is over how much these differences are the result of social pressures versus being rooted in our biology (the answer often is that there is a complex interaction between the two).
For example, when differences are observed between girls and boys, such as in preferences for play, one possibility is that this is partly or wholly because of the contrasting ways that girls and boys are influenced by their peers, parents and other adults (because of the ideas they have about how the sexes ought to behave). Studying non-human primates allows us to identity sex differences in behavior that can’t be due to human culture and gender beliefs.
Learning more about the biological roots of behavioural sex differences should not be used as an excuse for harmful stereotyping or discrimination, but it can help us better understand our human nature and the part that evolved sex differences play in some of the most important issues that affect our lives, including around diversity, relationships, mental health, crime and education.
“Many sex differences in behavioral development exist in nonhuman primates,” she writes, “despite a comparative lack of sex-biased treatment by mothers and other social partners”. Here is a digested account of five of these behavioural sex differences:
If you want to know what a woman is really thinking, ask another woman. That’s the message of a new study, published in Frontiers in Psychology, which was designed to probe our ability to use other people’s posture, facial expressions and behaviours, as well our interpretations of ambiguous statements, to infer what’s going on in their mind – no matter what they’re actually saying.
The research team, led by Renata Wacker at the Free University of Berlin, Germany, recruited 304 women and 241 men, ranging in age from 17 to 70. The volunteers were put through possibly the most irritating – though potentially clinically useful – movie-watching experience imaginable.
The hot-headed “macho man”, who acts first and thinks later, has long been popular in movies. Now there’s psychological evidence to support it. A new study in the Psychological Science finds that a short-term rise in testosterone – as might occur when in the presence of an attractive potential mate, or during competition – shifts the way men think, encouraging them to rely on quick, intuitive, and generally less accurate, judgements, rather than engaging in careful, more deliberate thought.
Most brain imaging studies involving transgender people or people with gender dysphoria have focused on whether their brains look more like what’s typical for the gender they identify with, rather than the gender they were assigned at birth based on their biological sex. For example, whether trans men have “masculine” brains, and trans women have more “feminine” brains.
The results have been mixed and if anything point towards trans people having brains with distinctfeatures that are neither stereotypically male or female.
A new study in Brain Imaging and Behaviour adds to this trend, showing that trans men have unusual patterns of connectivity in brain networks involved in processing of the self, as compared with male and female controls. “The present data do not support the hypothesis that sexual differentiation of the brain of individuals with gender dysphoria is in the opposite direction as their sex assigned at birth,” the researchers said, adding that the unusual connectivity patterns they found in trans men “was detected in comparison with both male and female controls, and there were no differences between the control groups”.
While the idea that the lack of women in science and tech is entirely about cultural obstacles is contentious (as demonstratedby the recent Google memo furore), few would argue that social and cultural factors aren’t important. And these social influences may begin early. For example there’s an argument that boys are encouraged to play with toys that are likely to promote skills that will help them in science and maths. Toys aimed at girls, in contrast, are more likely to promote stereotypically feminine skills, such as nurturing.
LEGO, say Megan Fulcher and Amy Hayes, the authors of a new paper in the journal Sex Roles, is a case in point: its marketing is skewed towards boys, especially since the increase in packaged sets, which tend to feature stereotypically masculine items like pirate ships and castles. The result, they argue, is that boys are more attracted to LEGO, girls deterred from it, and that boys get to practice their building skills while girls don’t.
LEGO has heard some of this criticism (and no doubt also seen a gap in the market) and they’ve released girl-friendly packaged sets and product lines, including Friends items with a focus on people and including pink bricks. But Fulcher and Hayes – who very much speak from the nurture perspective on these issues (they fail to cite a single study demonstrating a biological basis for sex differences in toy preference) – fear this could be counterproductive because girlie bricks and sets are likely to promote more stereotypically feminine LEGO play and remind girls of their gender. To find out if their concerns are justified the researchers tested the LEGO building skills and choices of 116 girls and boys (aged 5 to 10) depending on whether they were given boyish LEGO bricks and packages or girlie ones.
A new analysis of elite tennis performance in the Journal of Economic Psychology is consistent with this account. Based on the outcome of thousands of games played across the four tennis Grand Slams in 2010, the researchers led by Danny Cohen-Zada at Ben-Gurion University of the Negev, found that men were adversely affected by high pressure by about twice as much as women. Extrapolating to the world of work, Cohen-Zada and his colleagues said this casts doubt on the argument that the gender pay gap is due to women’s inability to compete under pressure, though they acknowledged there are caveats to this conclusion.
In a ranking of genuinely important YouTube videos to have gone viral, this one (see above) from 2014 places high: it shows over 100 instances of harassment endured by a woman wearing a hidden camera as she walked around New York City for ten hours, including comments, stares, winks and whistles.
The video was posted in 2014 by the domestic violence activist group Hollaback! to highlight the prevalence of this kind of behaviour. As individual testimony, it was powerful. But, critics could argue, it was just one woman, on just one day. This is an argument they cannot use about the results of a new study, published in the British Journal of Social Psychology, which the researchers, led by Elise Holland at the University of Melbourne in Australia, believe is the first to capture just how common sexual harassment and “objectification” is in the daily lives of young women – and to show the possible impact on how women think about themselves.
As the first cohort of women leaders began pushing up against the glass ceiling, many hoped it would shatter… but it only cracked. Today fewer than 10 per cent of Fortune 500 companies are led by people from ethnic minority groups and women combined, and although the reasons are manifold, blame has been laid at the feet of the early pioneers themselves.
The accusation is that successful people from underrepresented groups act as gatekeepers, keeping out others to maintain their special status and to identify with the dominant majority (the most famous example being the Queen Bee syndrome where a female boss undermines other women). But new research from the Academy of Management Journal suggests a different and very understandable reason that minority members are cautious to show enthusiasm for increasing diversity – because they know it could spell disaster for their own career if they did.
A team of US researchers led by Lara Stemple at the UCLA School of Law has analysed data from several large federal crime victimisation surveys and they say their findings show that sexual offences by women against male and female victims are surprisingly common. Writing in Aggression and Violent Behaviour the researchers stress that they are in no way intending to minimise the human cost of sexual violence perpetrated by men. But they say their results are “sufficiently robust so as to compel a rethinking of long-held stereotypes about sexual victimisation and gender”.
