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?
Compounding the difficulties they have liking themselves, people with low self-esteem also tend to have poorer relationships. Previous investigations into why this may be haven’t made easy reading for the self-doubters. For instance, while they tend to claim that their partners have more negative views of them and love them less (than do people with more typical self-esteem), studies of their partners simply haven’t backed this up. This suggests that the neurotic and needy are projecting their insecurities and imperilling their relationships in the process.
But that is not the end of the story. People with low self-esteem also tend to report that, when they need them most, their partners are poor at responding and being supportive. Is this all in their heads too? Not according to a series of studies in the Journal of Personality, by Kassandra Cortes and Joanne Wood at the University of Waterloo.
“Until this point, researchers have pointed the finger at LSEs [those with low self-esteem] as the likely cause for their lower quality relationships … However, our data suggest that LSEs may not be the only culprits,” Cortes and Wood conclude.
Early in 2018, the default reaction to encountering someone who disagrees with you is to place your fingers in your ears. The US government went into shut down following an impasse in Congress. Meanwhile, the UK remains bitterly divided over Brexit. We could all benefit from a dose of intellectual humility, according to the authors of a new paper in Self and Identity. People with this trait are open to other viewpoints and see disagreement as an opportunity to learn. Promisingly, early findings suggest that it may be possible to foster intellectual humility relatively easily, as least over the short term.
“Conferences on psychedelics are popping up everywhere, like mushrooms!” said Jakobien van der Weijden, of the Psychedelic Society of the Netherlands, when I met her in Amsterdam last week. Indeed, research into the use of psychedelic (mind-altering) drugs as tools in the treatment of depression, post-traumatic stress disorder and end-of-life angst, is on the increase. Psilocybin, the active ingredient in magic mushrooms, may help to alleviate symptoms of depression by altering brain activity in key areas involved in emotional processing, for example.
Now a study in the Journal of Psychopharmacology, led by Roland Griffiths at Johns Hopkins University, has found that for mentally and physically healthy volunteers, two doses of psilocybin in conjunction with a programme of meditation and other “spiritual” practices was enough to bring about lasting, positive changes to traits including altruism, gratitude, forgiveness and feeling close to others.
It’s a question that goes to the heart of human nature – do our personalities change through life or stay essentially the same? You might think psychology would have a definitive answer, but this remains an active research question. This is partly because of the practical challenge of testing the same group of individuals over many years. Now a major new contribution to the topic has been made available online at the PsyArXiv repository. The researchers, led by Eileen Graham at Northwestern University, have compared and combined data from 14 previously published longitudinal studies, together involving nearly 50,000 participants from the US, Europe and Scandinavia. Their findings confirm and extend existing knowledge, showing how personality traits tend to change through life in predictable ways.
Why are some of us more inclined than others to stick up for ourselves, not aggressively, but assertively. Assertive people let others know when they feel mistreated and they’re confident saying “no” to unwanted demands.
Presumably it has to do with how see ourselves, yet past research has established that two key aspects of the self-concept – good feelings about the self (“self-liking” or “self-confidence”) and seeing oneself as competent – are not strongly related to assertive behaviour.
Daniela Renger, a researcher at the Institute of Psychology at Kiel University in Germany, believes this is because most relevant to assertiveness is self-respect – “a person’s conviction that they possess the universal dignity of persons and basic moral human rights and equality”. Across three studies published in Self and Identity, Renger shows that self-respect is a distinct psychological concept and that it is uniquely correlated with assertive behaviour.
When you see someone laughing hysterically, do you often find yourself laughing too? Laughter is usually extremely contagious. In fact, we are up to 30 times more likely to laugh with someone else than when alone. It’s a powerful bonding tool: we enjoy seeing other people happy, we enjoy laughing with them, and this brings us closer together.
But is this equally true for everyone, or is laughter more contagious for some people than others? For a paper in Current Biology, a team of researchers at UCL, led by Elizabeth O’Nions and César F. Lima, has investigated whether adolescent boys at risk of psychopathy are less likely to find laughter catching.
What kind of parents produce creative children? Aside from the clear and substantial influence of the genes they pass on, evidence suggests that parents can also influence their children’s creativity through providing encouragement and the right environment. To understand what kind of parents are more inclined to take these steps, a new study in the journal Thinking Skills and Creativity investigates the links between mothers’ personality and how much they cultivate for their child a ”climate of creativity”.
Last week, Facebook’s founding president Sean Parker admitted his concerns that, by focusing on social validation, Facebook was designed to exploit “a vulnerability in human psychology”. Added to this, and amidst the current furore around fake news, imagine if adverts on Facebook could be adapted to target your personality, significantly increasing the odds that people like you will click on the ads and then buy the associated products or vote differently in an election. A timely study in PNAS shows just how easy and effective it is to target web users according to their personality, a technique that the researchers call “psychological persuasion”.
One year ago today, Donald J Trump, a man with no political or military experience, defied expectations, winning the election to become the 45th president of the United States. Nearly 63 million voted for him, including, and in spite of his reputation for sexism, over half of all white women. In an open-access paper in Evolutionary Studies in Imaginative Culture, Dan McAdams, one of the world’s leading experts in personality psychology, proposes an explanation for Trump’s popular appeal that is grounded in evolutionary psychology, personality theory and the social psychology of leadership.
