It sounds like a paradox – the idea that participating in aggressive sport can make people less aggressive. Yet this belief forms a core basis of many martial arts dating back thousands of years, and many famous practitioners (real and fictional) have preached the importance of self control.
Legendary martial artist Bruce Lee once noted that “emotion can be the enemy. If you give into your emotion, you lose yourself”. Or as Mr Miyagi said in The Karate Kid the “lesson is not just karate only, the lesson is for whole life”.
Previous research has demonstrated that this may well be the case, as participating in martial arts helps improve concentration and self-awareness, self-esteem, emotional stability and self-regulation.
But is it really true that martial arts also reduces aggression outside the dojo? Can participating in traditionally violent sports prove cathartic, helping young people develop self-discipline and in turn be less violent away from the sport? Writing in the journal of Aggression and Violent Behaviour researchers from Israel and America report their findings from the first meta-analysis on the impact of martial arts on violent behaviours in children and teenagers.

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.

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”.

The horrific killing of Catherine “Kitty” Genovese in New York in 1964 inspired research into what’s known in social psychology as the Bystander Phenomenon – our increased disinclination to intervene when in the company of others. That’s because early reports told how 38 witnesses to Genovese’s murder did nothing to help. But in fact it’s now clear that several people did intervene. So the tragedy that inspired research into the Bystander Phenomenon is actually a bad example of that real phenomenon.
But it’s not time yet to leave the sad story alone. As psychologist Saul Kassin documents in Perspectives on Psychological Science, hidden in the story in plain sight all these decades is an example of another important psychological principle: the power of false confessions. Moreover, in another twist, details have emerged recently of how a few days after her murder, Genovese’s killer, Winston Moseley, was initially detained by members of the public – ironically, given how the Genovese case inspired research into bystander apathy, these bystanders chose to act.

When someone breaks the speed limit, we tend to explain it away as recklessness, machismo, or impatience. But new research led by Vanessa Bowden at the University of Western Australia, suggests that problems in memory, not temperament, may often be the culprit. According to a recent study in the Journal of Experimental Psychology, traffic stops and other interruptions can disrupt our ability to keep track of recent changes to the speed limit. But the research doesn’t entirely let us off the hook: when waiting at a stop, we can reduce these interfering effects by making sure we keep our attention on the road.

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.

There has been little research into what it’s like for police detectives to investigate the death of a child. As bluntly stated in official police guidance documents “children are not meant to die”, and coping with these circumstances, especially as a detective and parent, could involve emotional and psychological demands beyond those experienced when investigating adult murders.
For a new explorative study in the Journal of Police and Criminal Psychology, Jason Roach and his colleagues surveyed 99 police detectives from 23 forces across England and Wales: most of them were white and male, and they had conducted investigations into an average of 30 adult murders and 7 unexplained child deaths. Compared to dealing with adult homicides, the detectives said they felt more pressure to solve cases involving children, found them harder to deal with emotionally, and thought more about them after the cases had ended.

To maintain pleasant public spaces requires that we all implicitly agree to certain civil behaviours, like pocketing our chocolate wrappers rather than leaving them strewn on the pavement, or turning the stereo down after eleven. But when these implicit agreements are too frequently ignored they can lose their force entirely, jeopardising the social order. To keep things together, one or more of us need to hold any miscreants to account… but who wants that hassle? A new paper in the journal Rationality and Society explores real-life littering norm enforcers, taking us from the streets of Switzerland to the New York underground.

Experiments suggest that telling if two unfamiliar faces are the same or different is no easy task. Such research has sometimes presented participants with full body shots, has more commonly used cropped shots of people’s heads, but almost never placed the faces in a formal context, such as on a photographic ID card. But these are the situations in which face-to-photo matching is most relevant, when a shop assistant squints at a driver’s license before selling alcohol to a twitchy youth, or an emigration official scrutinises passports before their holders pass ports. Moreover, it’s plausible that the task is harder when juggling extra information, something already found in the realm of fingerprint matching, where biographical information can lead to more erroneous matches because it triggers observer prejudices. A new article in Applied Cognitive Psychology confirms these fears, suggesting that our real-world capacity to spot fakes in their natural setting is even worse than imagined.

Tom Tate’s second visit to the German town of Pforzheim was a return to somewhere he hadn’t seen in fifty years. After bailing from a burning plane, he and his RAF squad had landed there, been captured, and his comrades executed by a Hitler Youth group incensed by the bombing the town had suffered. Tate himself had only escaped by moments, and swore never to return to a place that he believed bore only hate against him. But spurred by a magazine article that mentioned an annual service held to commemorate the atrocity, he decided to make the journey. Once there, he found himself welcomed by a population who deeply regretted their actions.
This story opens a new article in the Journal of Personality and Social Psychology, which investigates whether we underestimate how much our persecutors seek forgiveness. Relevant here is classic research that suggests a difference of perspective in how we judge people’s actions – we see our own actions as being strongly influenced by the situation we’re in, but when judging other another person’s actions we seem him or her as more directly responsible (sometimes described as the actor-observer bias). Researchers Gabrielle Adams and M. Ena Inesi thought that the same bias might be relevant to when one person harms another – that victims will typically assume the perpetrator intended his or her actions and will therefore remain unrepentant.
