Your personality traits play an important part in how long you are likely to live, as much as, or even more than, other personal factors like your intelligence and your family’s economic background. Now a study in the Journal of Research in Personality has identified a key factor that mediates the personality-mortality link – sleep. Simply put, people with certain personality characteristics are more likely to sleep too little, or too much, or to experience greater sleepiness during the day, and in turn this raises their year-on-year risk of dying (too little or excess sleep, and poor quality sleep, have known links with various health risks, such as cardiovascular disease, depression and chronic inflammation).
“Sleep has been associated with both personality and longevity, yet [before now] no study has investigated whether sleep is a pathway linking personality to objective health outcomes,” say the researchers, led by Shantel Spears at West Virginia University.

You can have £10 today or £12 next week. Which do you go for?
Being able to forego a reward now in favour of gaining something better later is known to be important in determining all kinds of desirable outcomes in life, including greater educational attainment, social functioning and health.
However, choosing to delay gratification won’t always be the best option. If you’re in desperate circumstances – you badly need money to buy food, for example – taking the £10 today could be sensible. But this isn’t necessarily an entirely conscious judgment – there may be biological systems that automatically shift your decision-making priorities according to what is most likely to enhance your survival. A new open-access study published in Scientific Reports provides evidence that having raised levels of inflammation in your body, which is generally caused by the immune system’s response to infection or injury, can skew your judgment to focus more on present rewards, and on instant gratification. If further research backs this up, there could be wide-ranging implications not only for understanding why some people are more impulsive than others, but even for treating substance abuse.

We all know the powerful effect that music can have on mood. You might be feeling rather chirpy, but then a tear-jerker comes on the car radio and you arrive home feeling morose (conversely, of course, happy tunes can lift our spirits). For most of us, these effects are not a big deal. But what if you are living with depression? Now the implications become more serious. And, according to a provocative study published a few years ago, far from seeking out uplifting music, people diagnosed with depression are notably more inclined than healthy controls to choose to listen to sad music (and look at sad images). The controversial implication is that depressed people deliberately act in ways that are likely to maintain their low mood. Now a study in the journal Emotion has replicated this finding, but the researchers also present evidence suggesting depressed people are not seeking to maintain their negative feelings, but rather that they find sad music calming and even uplifting.
“The current study is the most definitive to date in probing depression-related preferences for sad music using different tasks, and the reasons for these preferences,” write the team at the University of South Florida, led by Sunkyung Yoon.

Diversity trainings are big business. In the United States, companies spend about £6.1 billion per year, by one estimate, on programmes geared at making companies more inclusive and welcoming to members of often-underrepresented groups (British numbers aren’t easy to come by, but according to one recent survey, over a third of recruiters are planning to increase their investment in diversity initiatives).
Unfortunately, there’s little evidence-backed consensus about which sorts of diversity programmes work, and why, and there have been long-standing concerns in some quarters that these programmes don’t do much at all, or that they could actually be harmful. In part because of this dearth of evidence, the market for pro-diversity interventions is a bit of a Wild West with regard to quality.
For a new paper in PNAS, a prominent team of researchers, including Katherine Milkman, Angela Duckworth, and Adam Grant of the University of Pennsylvania’s Wharton School, partnered with a large global organisation to measure the real-world impact of the researchers’ own anti-bias intervention, designed principally to “promote inclusive attitudes and behaviors toward women, whereas a secondary focus was to promote the inclusion of other underrepresented groups (e.g., racial minorities).” The results were mixed at best – and unfortunately there are good reasons to be sceptical that even the more positive results are as positive as they seem.

In the era of social media and rolling news there’s a constant pressure to be in the know, always on hand with an aperçus or two. Today intellectual humility therefore feels more important than ever – having the insight and honesty to hold your hands up and say you’re ignorant or inexpert about an issue.
Psychologists are responding by taking an increasing interest in intellectual humility, including investigating its consequences for learning and the thinking styles that support it. For a new paper in The Journal of Positive Psychology a team led by Elizabeth Krumrei-Mancuso have continued this endeavour, showing, among other things, that intellectual humility correlates with superior general knowledge. This is a logical outcome because, as the researchers write, “simply put, learning requires the humility to realise one has something to learn.”

Psychologists have devoted much time over the last two decades documenting the dark side of human nature as encapsulated by the so-called Dark Triad of traits: psychopathy, Machiavellianism, and narcissism. People who score highly in these traits, who break the normal social rules around modesty, fairness and consideration for others, seem to fascinate as much as they appall. But what about those individuals who are at the other extreme, who through their compassion and selflessness are exemplars of the best of human nature? There is no catchy name for their personality traits, and while researchers have studied altruism, forgiveness, gratitude and other jewels in our behavioural repertoire, the light side of human personality has arguably not benefited from the same level of attention consumed by the dark side.
Writing in the journal Frontiers in Psychology, a team led by US psychologist and author Scott Barry Kaufman at Barnard College, Columbia University says it is high time we redressed this imbalance. “Too much focus on one aspect of human nature at the expense of the other misrepresents the full capacities of humanity,” they write. Through four studies featuring more than 1,500 online participants, Kaufman and his team have created a new questionnaire that taps what they are calling the Light Triad (see example items below, and you can take the test online). They’ve also provided preliminary evidence for the kind of personal characteristics and psychological outcomes that are associated with being a high scorer on the light side of personality – or what they call an “everyday saint”.

In the first study of its kind, researchers have asked people to describe in their own words what it’s like to live with Avoidant Personality Disorder (AVPD) – a diagnosis defined by psychiatrists as “a pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation”. Like all personality disorder diagnoses, AVPD is controversial, with some critics questioning whether it is anything other than an extreme form of social phobia.
To shed new light on the issue, lead author Kristine D. Sørensen, a psychologist, twice interviewed 15 people receiving outpatient treatment for AVPD: 9 women, 6 men, with an average age of 33, and none of them in work. Writing in the Journal of Clinical Psychology, Sørensen and her colleagues said the overarching theme to emerge from the in-depth interviews was the participants’ struggle to be a person. “They felt safe when alone yet lost in their aloneness,” the researchers said. They “longed to connect with others yet feared to get close.” In the researchers’ opinion, the participants’ profound difficulties with their “core self” and in their dealings with others do indeed correspond to “a personality disorder diagnosis”.

It’s well known that teenagers’ moods go through drastic changes. In particular, depressive symptoms – like feelings of low mood or self-loathing – tend to increase as they grow older. Now researchers have plotted out the exact trajectory of these depressive symptoms. In their recent paper in Journal of Youth and Adolescence, Alex Kwong and colleagues from the University of Bristol report for the first time the points during teen development when symptoms increase most rapidly, on average – and they find that these timings differ between young men and women.

When it comes to the heated subject of differences between how men and women behave, debate in psychology has centered on mate preferences and general interests. The available research shows that when it comes to (heterosexual) mating preferences, men are relatively more interested in physical beauty, while women are relatively more interested in earning capacity. As for general interests, men are more interested in physical things, while women are more interested in people.
Even the staunchest evolutionary psychologists would acknowledge these are partially overlapping bell curves: There are plenty of men who are fascinated by other people, and plenty of women looking for physical beauty in a partner above all else. Yet the findings have been met with fierce resistance in some quarters. One of the more sophisticated rejoinders is known as social roles theory: The differences do exist, but they’re entirely or largely the result of gender roles imposed by society on individuals. However, a new study released as a preprint at PsyArXiv and involving participants from 36 countries has failed to replicate a key finding that’s previously been cited in support of social roles theory.

Loneliness not only feels bad, experts have characterised it as a disease that increases the risk of a range of physical and psychological disorders. Some national prevalence estimates for loneliness are alarming. Although they can be as low as 4.4 per cent (in Azerbaijan), in other countries (such as Denmark) as many as 20 per cent of adults report being either moderately or severely lonely.
However, there’s no established way of identifying loneliness. Most diagnostic methods treat it as a one-dimensional construct: though it can vary in degrees, someone is either “lonely”, or they’re not. A new approach, outlined in a paper published recently in Social Psychiatry and Psychiatric Epidemiology, suggests that loneliness should in fact be divided into three sub-types, two of which are associated with poor mental health.
