Sorry romantics, new findings suggest love at first sight is really lust at first sight

Reporter: “When did you know she [Meghan Markle] was the one?”

Prince Harry: “The very first time we met”

It’s a trope of Hollywood: when two people realise in an instant that they have met the one they want to spend the rest of their lives with. In reality too, happy long-term couples will tell you, perhaps a little too smugly, and doing that gazing into each other’s eyes thing, how it was simply “love at first sight”. Mutual, of course.

We’re sorry to spoil the mood music, but a new paper in Personal Relationships – one of the first attempts to study this phenomenon scientifically – concludes that while believing one has fallen instantly in love does seem to be a genuine experience, it’s not really about love at all, but more to do with physical attraction (and it’s rarely mutual). And while people who remember having fallen in love with their partner at first sight do describe their relationship as more passionate in the present, their recall is probably little more than a “confabulated memory” – a “projection of their current feelings into the past”.

Men and women interpret the sexual intent behind dating behaviours very differently

Men tend to overestimate the sexual intent behind women’s behaviours on a date

By Alex Fradera

Imagine you’re out one evening with someone you met recently – you take your date’s hand in yours, or compliment your date’s appearance, or you kiss him or her passionately. For each behaviour, how likely is it that you wanted to have sex with that person for the first time? Researchers have put this question to heterosexual women, then they’ve asked men how they would interpret a woman’s intentions if she had behaved in these ways. The contrast in their answers is striking: men judge woman’s sexual intent as much higher than women do.

We could conclude from this that men read sex into situations where it isn’t there. But another explanation could be that men aren’t far off – it’s just that women under-report their true intentions. Which is closer to the truth? And what about men’s own sexual intentions – do women get those right?

In a new article in the Journal of Personality and Social Psychology, involving hundreds of US participants recruited online, Isabelle Engeler from IESE Business School and Priya Raghubir at New York University shine some light on the different ways men and women interpret the same dating behaviours.

The Psychology of Sex Differences – 5 Revealing Insights From Our Primate Cousins

By Christian Jarrett

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.

Earlier this year, as part of a special issue of the Journal of Neuroscience Research – titled “An Issue Whose Time Has Come: Sex/Gender Influences on Nervous System Function” – Elizabeth Lonsdorf at Franklin and Marshall College published a useful mini-review detailing some of the sex differences observed among monkey and ape infants and juveniles.

“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:

How short-term increases in testosterone change men’s thinking style

Competitive situations or the presence of attractive potential mates can lead to the short-term testosterone increases that were the focus of the new research

By Emma Young

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.

Trans men show unusual connectivity patterns in brain networks involved in self perception

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 distinct features 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”.

For one week these women recorded all the times they were objectified sexually

By Emma Young

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.

Sexual offending by women is surprisingly common, claims US study

By Christian Jarrett

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”.

What is it like to be the partner of someone who is transgender?

The experiences of people who’ve been through a gender transition have been studied and analysed by psychologists – showing, for example, improved psychological wellbeing and self-esteem after hormone treatment. But when it comes to their partners, there’s been much less research. According to a new study in the Journal of Social and Personal Relationships, though, they often go through a kind of life transition of their own, and while there are certainly challenges, there are often positive changes, too.

Psychologists are working on a fraud-proof brain scan test of deviant sexual interest

If the courts wanted to know if a suspected sex offender was attracted to children, they could ask him or her, or they could ask experts to measure signs of the suspect’s sexual arousal while he or she looked at different images. But a devious suspect would surely lie about their interests, and they could distract themselves to cheat the physical test.

Brain scans offer an alternative strategy: research shows that when we look at images that we find sexually attractive, our brains show distinct patterns of activation. But of course, the same issues of cheating and deliberate distraction could apply.

Unless, that is, you could somehow prevent the suspect from knowing what images they were looking at, by using subliminal stimuli that can’t be seen at a conscious level. Then you could see how their brain responds to different types of image without the suspect even knowing what they were looking at.

This is the essence of a strategy tested in a new paper in Consciousness and Cognition. Martina Wernicke at Asklepios Forensic Psychiatric Hospital of Gottingen and her colleagues have provided a partial proof of principle that it might one day be possible to use subliminally presented images in a brain scanner to provide a fraud-proof test of a person’s sexual interests. It’s a potentially important break-through for crime prevention – given that deviant sexual interest is one of the strongest predictors of future offences – but it also raises important ethical questions.

Attractive people have shorter relationships and are more interested in alternative partners

By Christian Jarrett

You probably won’t be reaching for your violin too quickly but a series of new studies provide compelling evidence that beauty is a kind of “relationship liability”. While more physically attractive people have a clear advantage when it comes to finding partners, the results suggest that their relationships are more likely to breakdown, at least in part because they take greater interest in alternative partners, especially when dissatisfied in their current relationship.

The results add further nuance to our understanding of how physical beauty impacts people’s lives. While good-looking folk seem to enjoy many advantages in life, on average, such as higher pay, more happiness and others assuming they are friendly and intelligent, it seems there are complicating factors: jealousy is one, and this new research, published in Personal Relationships, suggests that less stability in their romantic relationships is another.
