Brazilian Researchers Say Smartphone Addiction Is Real, And That It’s Associated With Impaired Decision-making

Smartphone addiction (SA) is a controversial concept that is not recognised by psychiatry as a formal diagnosis. Critics say that a problematic relationship with one’s phone is usually a symptom of deeper underlying issues and that it is inappropriate to apply the language of addiction to technology. Nonetheless, other mental health experts believe SA is real and they’ve accumulated evidence suggesting it is associated with reductions in academic and work performance, sleep disorders, symptoms of depression and loneliness, declines in wellbeing – and an increased risk of road traffic accidents. According to a group of psychiatry and psychology researchers at one of the largest universities in Brazil, to that list can now be added: poorer decision-making. 

Studies suggest that the numbers of people with notional SA (defined by difficulty in controlling use of the smartphone, constant preoccupation with the possibility of being without it, and poor mood when it is taken away) are high – about 25 per cent of the population in the US; 10 per cent of adolescents in the UK; and a massive 43 per cent of people in Brazil, where the new research, published in Frontiers in Psychiatry, was conducted.

These Violent Delights Don’t Have Violent Ends: Study Finds No link Between Violent Video Games And Teen Aggression

Claims that violent video games lead to aggression have been around since the days of Space Invaders. When young people are exposed to violent media, the theory goes, their aggressive thoughts become more prominent, leading them to commit acts of violence. But while several studies have found results that seem to back up this idea, the evidence is far from unequivocal.

Now a study published in Royal Society Open Science has failed to find any association between the time spent playing violent video games and aggressive behaviour, adding to a growing body of literature that suggests that such a link has been overstated – or may not exist at all.

Psychologists claim outrage is getting a bad rap

Outrage: It’s absolutely everywhere. Today’s world, particularly the version of it blasted into our brains by social media, offers endless fodder, from big, simmering outrages (climate change and many powerful institutions’ refusal to do anything about it) to smaller quotidian ones (every day, someone, somewhere does something offensive that comes to Twitter’s attention, leading to a gleeful pile-on).

In part because of rising awareness of the adverse consequences of unfettered digital-age outrage, and of journalistic treatments like So You’ve Been Publicly Shamed by Jon Ronson (which I interviewed him about here), outrage has become a particularly potent dirty word in recent years. Outrage, the thinking goes, is an overly emotional response to a confusing world, and drives people to nasty excesses, from simple online shaming to death threats or actual violence.

But a new paper argues that the concept of outrage has gotten too bad a rap and that its upsides, especially as a motivator of collective action and costly helping, have been overlooked. Writing  in Trends in Cognitive Sciences, the psychologists Victoria Spring, Daryl Cameron and Mina Cikara detail important questions about outrage that have yet to be answered, and they highlight how certain findings – especially from the “intergroup relations” literature, in contrast to the mostly negative findings from moral psychology – suggest it can serve a useful purpose.

Researchers find the most plausible cause of wellbeing decline in youth is increased screen time

A new paper analyses wellbeing and lifestyle data from over a million US youth

By Alex Fradera

Have young people never had it so good, or do they face more challenges than any generation? Our current era in the West is one of high wealth and relatively free of deprivation, meaning minors enjoy material benefits and legal protections that would be the envy of those living in the past. But there is an increasing suspicion that all is not well for our youth, and one of the most popular explanations, among some experts and the popular media, is that excessive “screen time” is to blame (all the attention young people devote to their phones, tablets and laptops). However, this is a contentious theory and such claims have been treated sceptically by some scholars based on their reading of the relevant data. 

Now a study in the journal Emotion has provided another contribution to the debate, uncovering strong evidence that adolescent wellbeing in the USA really is experiencing a decline, and arguing that the most likely culprit is the electronic riches we have given them.

Audiobooks pack a more powerful emotional punch than film

Audiobook sales are booming, almost doubling in the UK over the past five years. Some are now sophisticated, being voiced by multiple actors and featuring extensive sound effects. But even single-narrator audiobooks are, it’s been argued, more cognitively and emotionally engaging than print – in part because a listener can’t slow down, as they can with a print book. 

As a writer whose latest psychology-themed novel She, Myself and I is now being produced as an audiobook, I can’t help wondering about the benefits, and the costs. Personally, I like to be able to control my pace through a print book, to re-read sentences or paragraphs that I particularly enjoy or that I don’t quite process properly on a first read. 

However, as Daniel Richardson at UCL, and fellow researchers, point out in a new study, available as a pre-print on the bioRxiv service, “Our oldest narratives date back many thousands of years and pre-date the advent of writing… For the majority of human history, stories were synonymous with oral tradition; audiences listened to a story-teller imparting a tale.” Humans did not evolve to read, so perhaps there’s something primordially special about listening to a story. But, as the researchers go on to write, “in the modern era, video has emerged as a major narrative tool as well.” 

So which is more engaging – video or audio? That’s the focus of the new paper. And I’m intrigued. I’ve also sold TV rights to the novel, and TV, of course, is the medium of mass-appeal. If my book is ultimately turned into a TV series, might viewers become more involved in the story than my audiobook listeners?

Psychologists have looked into why “phubbing” is so harmful to our social lives

If you are with someone who is ignoring you while they interact with their smartphone, you have been phone snubbed, or “phubbed”. Phubbing is common, at least in Western cultures – in a recent US survey, nine out of ten respondents said they had used their smartphone during their most recent social activity. There’s also evidence that it is socially harmful, leaving people less satisfied with their face-to-face interactions and generating feelings of resentment and jealousy. Now the Journal of Applied Social Psychology has published a new study exploring the reasons for these effects.

Researchers say it is mistaken to see sexting as “simply harmful”

Is sexting a good thing, because it’s sexually liberating, or a bad thing, because it’s objectifying? Separate research groups have put forward both arguments. But according to a new study of college students in Hong Kong, it’s both. 

It’s estimated that roughly half of US college students (on which most research in this area has been done) send nude or sexually provocative images by phone or the internet. In the new study, reported in the Journal of Sex Research, the proportion was lower (13.6 per cent), perhaps because Chinese culture has a lower level of sexual permissiveness, but sexting was still relatively common, with almost one in five men and one in ten women saying they do it.

Sending a supportive text to your partner can reduce their physiological stress levels, but only if you’re subtle about it

The average young adult sends more than 100 texts per day, mainly to offer social support to friends and family. But until now, there has been little evidence whether it helps the recipient or not. New research in Computers in Human Behavior confirms that sending a comforting text to a partner confronted with a difficult task really can make them feel supported. But more surprisingly, the study suggests that to actually reduce their stress, it’s better to send a message that isn’t explicitly supportive.

Taking a photo of something impairs your memory of it, but the reasons remain largely mysterious

By Alex Fradera

Avid photographers celebrate the viewfinder as a means of helping us see the world anew. But psychology research has shown that under some conditions taking a photo of something actually makes it harder to remember. One possible reason is that we give less attention to an experience when we know that it will be safely stored in a photograph. But in a new paper in the Journal of Applied Research in Memory and Cognition, Julia Soares and Benjamin Storm from the University of California show that the photo-taker’s memory will suffer whether they expect to keep the photo or not.

Brain differences in avid players of violent video games suggest they are “callous, cool and in control”

Video games do not enjoy the best of reputations. Violent games in particular have been linked with aggression, antisocial behaviour and alienation among teens. For example, one study found that playing a mere 10 minutes of a violent video game was enough to reduce helping behaviour in participants.

However, some experts are sceptical about whether games really cause aggression and, even if the games are to blame, it remains unclear what drives their harmful effects. Earlier studies identified empathy as a key trait that may be affected by violent gameplay. Now a study by Laura Stockdale at Loyola University Chicago and her colleagues in Social Affective and Cognitive Neuroscience has taken a closer look at how gamers and non-gamers differ at a neural level, uncovering evidence that suggests chronic violent gameplay may affect emotional brain processing, although more research is needed to confirm this.
