We’re taught from an early age that it is polite and assertive to look people in the eyes when we’re talking to them. Psychology research backs this up – people who make plenty of eye contact – as long as it’s not excessive – are usually perceived as more competent, trustworthy and intelligent. If you want to make a good impression, then, it’s probably a good idea to meet the gaze of the person you’re talking to. However, following this advice is not necessarily straight-forward for everyone. It’s well-documented that mutual gaze can be emotionally intense and distracting, even uncomfortably so for some.
If this is your experience, you may welcome a study published recently in the journal Perception that documents a phenomenon known as the “eye contact illusion” – put simply, we are not that good at telling whether an interlocutor is looking us in the eye or not. In fact, we tend to think they are, even when they’re not (a bias that is magnified after we’ve been rejected). Thanks to this illusion, you can give the impression of making eye contact simply by ensuring you are looking in the general direction of your conversant’s face.
If you want to know about the special relationship between human and canine you need only watch a dog owner slavishly feed, cuddle and clean up after her furry companion, day after day after day. But is this unique cross-species relationship also reflected at a deeper level, in the workings of the canine brain? A recent study in Learning and Behavior suggests so, finding that highly trained dogs have a dedicated neural area for processing human faces, separate from the area involved in processing the faces of other dogs.
The researchers, led by Andie Thompkins at Auburn University, say their results are of theoretical importance (in relation to the evolutionary origin of cognitive abilities) and could have practical use too, potentially paving the way to using brain scans to validate the expertise of trained dogs.
We make all kinds of snap decisions about a person based on their facial appearance. How trustworthy we think they are is one of the most important, as it can have many social and financial consequences, from influencing our decisions about whether to lend someone money to which Airbnb property to book.
However, as the authors of a new study, published in the British Journal of Psychology, note, “Although facial impressions of trustworthiness are formed automatically, they are not especially accurate predictors of trustworthy behaviour.” People who are less susceptible to forming these impressions could, then, be at an advantage. And, as Jasmine Hooper at the University of Western of Australia and colleagues now report, men with high levels of autistic traits fall into this category.
“Update: On Twitter, some researchers argued, reasonably in my view, that I wasn’t quite sceptical enough in relating these findings. See the update at the end of this post for more details.”
If you wanted a poster child for the replication crisis and the controversy it has unleashed within the field of psychology, it would be hard to do much better than Fritz Strack’s findings. In 1988, the German psychologist and his colleagues published research that appeared to show that if your mouth is forced into a smile, you become a bit happier, and if it’s forced into a frown, you become a bit sadder. He pulled this off by asking volunteers to view a set of cartoons (paper ones, not animated) while holding a pen in their mouth, either with their teeth (forcing their mouth into a smile), or with their lips (forcing a frown), and to then use the pen in this position to rate how amused they were by the cartoons. The smilers were more amused, and the frowners less so – and best of all, they mostly didn’t discern the true purpose of the experiment, eliminating potential placebo-effect explanations.
This basic idea, that our facial expressions can feed back into our psychological state and behavior, goes back at least as far as Darwin and William James, but “facial feedback”, as it is known, had never been demonstrated in such an elegant and rigorous-seeming manner. Over time, this style of experiment was replicated and expanded upon, and soon it came to be considered a true blockbuster, so famous it found its ways into psychology textbooks, as well as popular books and articles citing it as an example of the unexpectedly subtle ways our bodies and environments can affect us psychologically. Often, facial feedback has been popularised along the lines of Maybe you can smile your way to happiness!, which added an irresistible self-help element that likely helped spread the idea. Either way, it seemed like a genuinely safe and solid psychological finding. That changed rather abruptly in 2016.
Now a team led by Sarah Ketay at the University Hartford have shown how this absorption of friends into our self-concept can manifest at a visual level, affecting our ability to distinguish their faces from our own. Writing in the Journal of Social and Personal Relationships, Ketay’s team said “The present research supports the idea that close others are processed preferentially and may overlap with the self.”
You’re at a ten-pin bowling alley with some friends, you bowl your first ball – and it’s a strike. Do you instantly grin with delight? Not according to a study of bowlers, who smiled not at a moment of triumph but rather when they pivoted in their lanes, to look at their fellow bowlers.
That study provided the earliest evidence for a controversial hypothesis, the Behavioural Ecology View (BECV) of facial displays, outlined in detail in a new opinion piece in Trends in Cognitive Sciences. Carlos Crivelli at De Montfort University, Leicester, UK and Alan Fridlund at the University of California, Santa Barbara, put forward the case that facial displays are not universal, “pre-wired” expressions of emotion – a concept supported by 80 per cent of emotion researchers in a recent poll – but are flexible tools for influencing the behaviour of other people.
In the adverts for anti-ageing skin products, everyone is smiling, positively blooming with youthfulness. A canny move by the marketeers you might think – after all, past research has found most of us believe smiling makes people look younger. It’s just that actually, it doesn’t. It makes you look older. That’s according to a new paper in Psychonomic Bulletin and Review that explores an intriguing mismatch between our beliefs and perceptions.
What can we tell about someone from their face? Their favoured facial expressions can hint at their temperament, the weathering of their skin at their life history, their facial hair and makeup at their aesthetic taste. But now, new research in the journal Attitudes and Social Cognition suggests that we can also intuit their names, because a person’s given name influences their facial appearance in adult life. On the face of it (sorry) this is hard to believe, but the case, made across eight studies, is based on plenty of careful evidence, and also proposes a plausible explanation.
Scientists are increasingly encouraged to communicate directly with non-experts, through newspaper and TV interviews, science festivals, online videos, and other channels. But the quality of their research or ideas alone is not enough to guarantee interest or support, suggests a series of new studies in PNAS. The way the general public responds is also influenced by the scientist’s facial appearance, an important finding, say the researchers, because the public communication of scientific findings shapes beliefs, opinion and policy.
It’s a stereotype that has improved a little over the years but still persists: women are more emotionally expressive than men. Like Bridget Jones, we constantly reveal exactly how we’re feeling, while men, Mark Darcy-like, look on impassively.
Although prior evidence suggests that women really do smile more often, a new study, published in PLOS One, has considered a greater variety of facial expressions, and it finds that the gender pattern is more complex, with some emotions displayed more by men than women. Arguably, this work helps to reveal not only differences in the emotional signals men and women send to others, but also differences in the emotions that we feel.
