Our weekly round-up of the best psychology coverage from elsewhere on the web
Scientists can predict what country people are from just by looking at how colours make them feel, reports Eva Frederick at Science. Researchers found cultural differences in how people associate colours and emotions: Chinese participants showed the strongest association between red and joy, for example, while Greek participants were the only ones to relate purple to sadness. The team then used machine learning to guess where people were from based on the associations they made.
Can a lie still be harmful if it’s never found out? New research on the relationship between dishonesty and social understanding may unsettle the fibbers amongst us. In a multi-study investigation with a total of 2,588 participants, scientists have found Pinocchio isn’t the only one to experience a few personal problems after telling lies.
In an era of TED talks, podcasts, and audiobooks, it’s easy to choose to listen to factual information or fiction, rather than to read it. But is that a good thing? Are there any differences in the way the brain processes the meaning of words that are heard rather than read? According to the researchers behind a thorough new study, published in the Journal of Neuroscience, the answer to this last question is “no”. But it may still be too soon to conclude that listening to an audiobook is effectively the same as reading it.
When a gym recently opened up near my house, I was determined to go regularly and make the most of the facilities. And I did — for about a month. But gradually, my visits became fewer and further between, until I realised I was paying for a bunch of machines and slabs of metal that I hadn’t touched in weeks. Guiltily, I cancelled my membership.
But perhaps I have my personality to blame. A new study tracking gym users has honed in one key factor that is related to how often they visit: their “planfulness”. This aspect of our personality, say the researchers, could be “uniquely useful” for predicting a range of goal-directed behaviours.

Imagine seeing a photograph of a suffering child in the war-torn region of Darfur, in Sudan. Most of us would feel compassion towards that child. Now imagine seeing a photo of a group of eight children in the same terrible predicament. You’d feel correspondingly more compassion towards this larger group… right?
Well, probably not. Plenty of studies have demonstrated what’s known as the “numeracy bias” in compassion — that people’s feelings of compassion do not tend to increase in response to greater numbers of people in distress. This “leads people frequently to experience a disproportionate amount of compassion towards a single suffering individual relative to scores of suffering victims that are part of a larger tragedy,” write Daniel Lim and David DeSteno at Northeastern University, in their new paper, published in the journal Emotion. However, they’ve now found that people who have experienced adversity in their own lives are resistant to this bias — and they have some suggestions for how the rest of us might avoid it.
Fast food chains are not exactly renowned for encouraging healthy eating. But in a new study a team of psychologists, eager to turn that assumption on its head, chose McDonald’s as their target for a somewhat unconventional, psychologically-informed health intervention. Writing in Psychology & Marketing, the researchers report successfully “nudging” a group of Coca-Cola-guzzling customers into opting for its sugar-free counterpart, Coke Zero — simply by changing the order of options on the menu.
The placebo effect is a curious phenomenon. A wealth of literature has shown that inert treatments can not only produce medical benefits like pain relief, but also have cognitive effects like boosting creativity and learning. And while many of those studies involve misleading people into thinking that they are receiving an effective intervention, a new study in Scientific Reports shows that this deception is not always necessary. Researchers have found that taking a placebo can reduce people’s anxiety before a test — even when they know they are taking an inactive pill.
You’re preparing for an important meeting, and the pressure’s on. If it’s bad now, how will you cope when you actually have to perform? Will you fly? Or will you sink?
Psychologists have a lot to say about how to cope under pressure… both the chronic kind, which might involve ongoing high expectations at work, for example; and the acute, single-event variety such as a vital meeting, a make-or-break presentation, or a sports match.Continue reading “How To Cope Under Pressure, According To Psychology”→
What kind of person posts a lot of selfies on their Instagram account? It has been suggested that such people are more narcissistic, but the research results on this are inconclusive. However, a new study, published in the Journal of Research in Personality, has found that whatever the actual personality traits of those who post plenty of selfies, other people have a clear opinion about them — and it’s not good.
If you hear an unfounded statement often enough, you might just start believing that it’s true. This phenomenon, known as the “illusory truth effect”, is exploited by politicians and advertisers — and if you think you are immune to it, you’re probably wrong. In fact, earlier this year we reported on a study that found people are prone to the effect regardless of their particular cognitive profile.
But that doesn’t mean there’s nothing we can do to protect ourselves against the illusion. A study in Cognition has found that using our own knowledge to fact-check a false claim can prevent us from believing it is true when it is later repeated. But we might need a bit of a nudge to get there.
