This Weird, Sound-Induced Illusion Makes You Feel That Your Finger Has Grown Longer

By Emma Young

Adults are vulnerable to all kinds of body illusions. We can be made to feel that a fake hand, or even a fake body, is our own; that we’ve left our body; even that we’re the size of a doll. These illusions work because our brains use information from various senses to create mental representations of our bodies. Mess with some of these sensory signals, and you can alter those representations, sometimes drastically.

Work to date suggests that young children don’t show the same susceptibilities to body illusions, presumably because the systems that underpin them are still developing. Now a new study, published in Scientific Reports, has found that a bizarre auditory-induced illusion that affects adults doesn’t work in quite the same way in young kids, either.

Bullies And Their Victims Show Different Patterns Of Brain Activity To Emotional Faces

By Emma Young

An estimated one quarter to one half of adolescents will at some point either be a victim of bullying, or engage in it — or both. Whether you’re on the receiving end, or dealing it out, there are all kinds of associated negative implications for mental health and well-being, including distress, depression and anxiety.  “This highlights an important need to understand the predictors of bullying and victimisation, in order to identify ways to reduce these experiences in adolescents,” write the researchers behind a new study, published in Social Cognitive and Affective Neuroscience. And this research has revealed one such factor: both bullies and victims show differences in the brain’s response to angry and fearful faces.

Speaking “Parentese” With Young Children Can Boost Their Language Development

By Emily Reynolds

Language learning can be a matter of much concern for new parents, who often worry about what their baby is saying, how they’re saying it, and when. With previous research suggesting that frequent verbal engagement with babies can boost vocabulary and reading comprehension, this preoccupation is not without merit. But even those parents who aren’t too fixated on baby’s first word may in fact be improving their offspring’s language, even if they’re not aware of it.

A form of speech dubbed “parentese” may be a key factor in improving language learning in infants, a new study in PNAS has suggested. Naja Ferjan Ramírez and colleagues from the University of Washington examined the distinctive form of sing-song speech often aimed at babies, finding that it improved conversation between parents and their children and even boosted language development.

Siblings Who Believe Their Family Has A Lower Social Standing Are More Likely To Experience Mental Health Difficulties

By guest blogger Sofia Deleniv

Most of us are not surprised to hear that a child’s chances of achieving success, physical health, and mental well-being depend heavily on the socioeconomic status of the family into which they are born. A large-scale global study commissioned by the World Health Organisation found that the lower the income of a family, the more likely their child is to suffer physical and mental health issues later in life, run into problems with the legal system, and die early.

But a physical lack of resources may not be the only factor driving poor outcomes. Last month, a study published in PNAS revealed that children’s perceptions of their family’s socioeconomic standing might matter more than how well their families are actually doing — at least when it comes to their mental health.

Kids Like Learning From Confident Adults — But Only If Their Confidence Is Justified

Schoolboys Work with their Teacher in Elementary Class

By Emma Young

If you confidently tell a young child a fact, they’re likely to believe you. But you’d better be right — because if they find out that you were wrong, and should have known better, they’ll doubt not only your credibility but your intelligence too.

These are the implications of new work in PLOS One, led by Susan Birch at the University of British Columbia. It shows that children prefer to learn from people who are consistently confident, rather than hesitant, about what they say. However, even kids as young as four also keep a track record of a person’s accuracy, and make judgements about them on this basis.

“We now know that children are even more savvy at learning from others than we previously thought,” says Birch. “They don’t just prefer to learn from anyone who is confident; they avoid learning from people who have confidently given wrong information in the past.” Continue reading “Kids Like Learning From Confident Adults — But Only If Their Confidence Is Justified”

Even Preschoolers Associate Positions Of Power With Being A Man

Gender inequality ConceptBy Emily Reynolds

An imbalance in power — personal and political — is at the heart of many of the conversations we have around gender. #MeToo sparked a global conversation on the topic, and issues around the gender pay gap and women in leadership roles also deal with matters of unequal power.

But our assumptions about how gender and power interact may start far before we even reach the workplace, new research suggests. In a paper published in Sex Roles, Rawan Charafeddine from the CNRS in Paris and colleagues conclude that associations between power and masculinity start when we’re barely out of nappies, with children as young as four making the link.

Episode 19: Should We Worry About Screen Time?

There's so much to learn onlineThis is Episode 19 of PsychCrunch, the podcast from the British Psychological Society’s Research Digest, sponsored by Routledge Psychology. Download here.

Do we worry too much about screen time? The issue of screen use by children and teenagers is rarely out of the headlines, and institutions including the World Health Organization have recommended specific limits on screen time for the youngest age groups. But what does the science actually say about the effects of screen time?

To find out, our presenter Ella Rhodes talks to Dr Amy Orben, Research Fellow at the University of Cambridge and winner of the 2019 BPS award for Outstanding Doctoral Research, who has explored the psychological effects of screen time in her research.

Lying To Your Kids Could Make Them More Dishonest And Less Well-Adjusted As Adults


By Emily Reynolds

Telling white lies to children can be somewhat par for the course when you’re a parent: “I’ve got Santa on the phone and he says he’s not coming unless you go to bed now,” is particularly useful during the festive season, for example.

It can seem like nothing: just another tool to improve your child’s behaviour. But don’t get too attached to the technique — telling too many white lies to your children may have more far-reaching consequences than you might have hoped, according to a new study, published in the Journal of Experimental Child Psychology.

Five Ways To Boost Resilience In Children


By Emma Young

While some of us crumble in the face of adversity, and struggle to recover, others quickly bounce back from even serious trauma. Psychological resilience is undeniably important in all kinds of areas of life, so understanding what underpins it, and how to train it – particularly in children — is of intense interest to psychologists.

The Most Popular Teens Gain Status Through A Combination Of Aggression And Kindness

By Emily Reynolds

For many teenagers, being popular is the ultimate form of success. But how to get there is not always so clear. Past research has identified two types of popular teens: the aggressive and the prosocial. Aggressively popular teens are more likely to be coercive or hostile whilst seeking popularity; the prosocial are co-operative and more likely to be stereotypically “nice”.

But in new research from Florida Atlantic University and the University of Montreal, published in Child Development, a third group has emerged: the “bistrategic” teen. This group is neither stereotypically aggressive nor stereotypically nice: instead, they walk the line, using aggression when needed but also being able to smooth things over with strategies usually seen in a more prosocial teen. And this seems to be such a successful tactic that these teens are the most popular of the lot.
