Hikikomori is a dark term that describes people who stay holed up in their homes, or even just their bedrooms, isolated from everyone except their family, for many months or years. The phenomenon has captured the popular imagination with many articles appearing in the mainstream media in recent years, but, surprisingly, it isn’t well understood by psychologists.
The condition was first described in Japan, but cases have since been reported in countries as far apart as Oman, Indian, the US and Brazil. No one knows how many hikikomori exist (the term refers both to the condition and the people with it), but surveys suggest that 1.79 per cent of Japanese people aged 15-39 meet the criteria. However, while some assumptions about risk factors have been made, based largely on reports of specific cases, there has been a lack of population-based research. A new study, published in Frontiers in Psychiatry, plugs some of the knowledge gaps.
Feeling good in an emotional sense helps to foster better physical health – at least that’s what’s been found in studies in the West. But “feeling good” doesn’t necessarily mean the same thing in all cultures. In the US, people tend to report that being excited and experiencing other so-called “high arousal positive (HAP) states” is what makes them feel good. Many people in Japan, however, place greater value on the opposite extreme, viewing calm, quiet “low arousal positive (LAP) states” as more pleasant and desirable. So, does this mean that engaging more often in stimulating activities – like a fitness work-out or a party – will make for better health in US citizens, while for people in Japan, engaging in more calming activities – like taking frequent baths – will have more of a beneficial effect? A new paper, published in Emotion, which explores this question, reveals some clear cultural variations – though not all of them are as the researchers predicted.
How important is your country, really? It’s a pointed question, especially with Brexit looming and the reinvigoration of nationalistic movements in the U.S. and EU. So it feels like a fitting time to look at a creative study that evaluated differences in, well, national self-importance.
Shame feels so awful it’s hard to see how it could have an upside, especially when you consider specific triggers of the emotion – such as body-shaming, which involves criticising someone for how their body looks. But is shame always an ugly emotion that we should try to do away with? Or can it be helpful?
The answer, according to a new study published in PNAS of 899 people from all over the world is that, as an emotion, shame can not only be useful but is fundamental to our ability to survive and thrive in a group. The essential job of shame, it seems, is to stop us from being too selfish for our own good.
Intelligence is a concept that some people have a hard time buying. It’s too multifaceted, too context-dependent, too Western. The US psychologist Edwin Boring encapsulated this scepticism when he said “measurable intelligence is simply what the tests of intelligence test.” Yet the scientific credentials of the concept are undimmed, partly because intelligence is strongly associated with so many important outcomes in life. Now Utah Valley University researchers Russell Warne and Cassidy Burningham have released evidence that further strengthens the case for intelligence being a valid and useful concept. Their PsyArXiv pre-print presents a cross-study analysis suggesting a single intelligence-like factor underpins mental performance across a wide range of non-western cultures.
No matter where they live, people interpret certain kinds of vocalisations, even from animals, as conveying a particular emotion – as “angry”, for instance, or “soothing”. It’s tempting to think that there might be similar cross-cultural universals in the ways that we use music – that a song used to calm an infant in Melanesia, say, should bear striking similarities to a song created for the same purpose by a culture in the Arctic Circle.
Well, it’s tempting if you’re a cognitive scientist – though not if you’re an ethnomusicologist (who studies music from different cultures), according to a survey of the opinions of academics reported in a new paper, published in Current Biology. “Historically, the idea that there might be universals in music from many cultures has been met with considerable scepticism, especially among music scholars,” note the authors of the study, led by Samuel Mehr at Harvard University, which then goes on to explore whether they do exist.
What lies at the dark heart of psychopathy? Is it a lack or emotion and empathy, a willingness to manipulate others – or, perhaps, a failure to take responsibility for misdeeds? All of these traits, and many more, are viewed as aspects of a psychopathic personality. But there’s still a debate among experts about which of these are core, and which less important.
Now a new study of 7,450 criminal offenders in the US and the Netherlands, published in the Journal of Abnormal Psychology, has identified what the researchers believe are the psychopath’s most “central” traits . But while there were striking similarities in the data from the two countries, there were also intriguing differences. This raises the question: does the meaning of the term “psychopath” vary between cultures?
Imagining ourselves as no longer existing is, for most of us, terrifying. Buddhism may offer some reassurance. A central tenet of the religion is that all is impermanent and the self is actually an illusion. If there is no self, then why fear the end of the self?
To find out if the logic of the Buddhist perspective eliminates existential fear, Shaun Nichols at the University of Arizona and his colleagues surveyed hundreds of monastic Tibetan Buddhists (monks-in-training) in exile in India, as well as lay Tibetans, Tibetan Buddhists from Bhutan, Indian Hindus and American Christians and atheists.
To their astonishment, the researchers report in Cognitive Science that fear of the annihilation of the self was most intense among the monastic Buddhists, and that the monastic Buddhists were less willing than any of the other groups to sacrifice years of their own life for a stranger.
Feeling positive emotions is good for your physical health, right? There’s certainly evidence in support of the idea. But it’s mostly come from studies of people living in Western countries. Now a study published in Psychological Science, concludes that for people in Japan, it may not be the case.
While positive emotions, like happiness, are seen as a good thing in the US, UK, and elsewhere in Europe, the picture is different in east Asia: they aren’t seen being as necessarily desirable, and negative emotions aren’t considered to be all that bad. As the researchers, led by Jiah Yoo at the University of Wisconsin-Madison, US, write in their introduction: “No study to date has directly compared the biological correlates of positive affect across cultures.”
Walter Mischel’s Marshmallow Test of self-control is one of psychology’s iconic experimental set-ups. First conducted in the 1960s, Mischel told the kids he tested that if they managed to resist eating the marshmallow in front of them until he returned (usually about 15 minutes later), they would be rewarded with a second marshmallow.
The children varied greatly in their powers of restraint and those who performed better displayed some cute distraction strategies, such as singing to themselves and covering their eyes. Perhaps most important, those kids who performed well at the test tended to do well in later life too, in terms of their health, education and career success. Given the huge impact this research has had, it’s amazing that it’s never been exported to a non-Western setting. Until now.
In a new paper in Child Development, Bettina Lamm and her colleagues have compared the performance of 125 4-year-olds from urban middle-class Germany with the performance of dozens of 4-year-olds from the Nso farming families of rural Cameroon. The Cameroonian kids aced the test, performing much better than their German peers. What’s more, their success seemed to be tied to the traditional, strict, hierarchical culture in which they’d been raised. The results challenge Western assumptions about what constitutes an ideal parenting style, and they provide another powerful demonstration of the urgent need for psychology to conduct more research outside of its usual Western focus.
