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.

“You know I’m automatically attracted to beautiful — I just start kissing them. It’s like a magnet. Just kiss. I don’t even wait. And when you’re a star, they let you do it. You can do anything.” Donald Trump, 2016 Republican Party nominee for US president, speaking in 2005 (full transcript).
The causes of sexual aggression are many, but anecdotal evidence (for example, as implied in the above quote), and research-based evidence, suggests that at least part of it has to do with when men overestimate women’s levels of sexual interest. A new study in the Psychology of Violence finds that men with a history of sexual aggression are especially likely to make this kind of misjudgment, in part because they focus on inappropriate cues, such as a woman’s attractiveness, rather than on her actual emotions. But promisingly, the research also suggests that it’s possible, through practice, to reduce this bias. This is an important finding considering previous research has shown that information-based educational programmes designed to reduce sexual aggression (through challenging rape myths, for example) are relatively ineffective.

Identifying people from video and photographs is a core task for a modern police force, and London – which led the world in implementing and using CCTV – has attempted to meet this need by developing a pool of 140 “police identifiers” made up of Metropolitan Police officers with a strong track record of making IDs from photographs. But who are these individuals? Are they really super-recognisers as the Met has claimed? True super-recognisers are usually identified by formal tests and their dramatic ability to recognise human faces outstrips typical performance to the same extent that many prosopagnosics (people with face-blindness) lag behind. Or, in identifying so many suspects, did the police identifiers just catch a string of lucky breaks? Addressing this through a battery of neuropsychological tests, Josh Davis and his UK-university collaborators scrutinise the scrutinisers in a new paper in Applied Cognitive Psychology. Continue reading “The Metropolitan Police’s elite super-recognisers are the real deal”→
In the 1970s, feminist theorists began to put forward what was then a controversial claim: that sexual aggression is essentially about power. This idea was important enough to launch experimental research, much of which has supported the claim – for instance, priming some men with a sense of power leads them to say they would be more prepared to coerce sex, and encourages men and women alike to believe a subordinate desired them sexually. However other research has suggested the opposite: that aggression is more likely when perpetrators feel less powerful, including in domestic violence and specifically sexual aggression contexts.
