Immediately after consensual and satisfactory sex, most people report feeling positive, content and psychologically close to their partner. But for some, it has the opposite effect, leaving them tearful and irritable for anything from a few minutes to a few hours. Commonly known as the “post-sex blues”, psychologists call it “post-coital dysphoria” (PCD) and until recently they had only studied it in women.
For example, in 2015, Robert D Schweitzer at the Queensland University of Technology led a study of 230 Australian female students, in which 46 per cent reported experiencing PCD at some point in their lives, and about 2 per cent said they experienced it regularly.
Now masters student Joel Maczkowiack and Schweitzer have published – in the Journal of Sex and Marital Therapy – the first ever study to show that some men suffer from PCD, too.
Why do some people go to great lengths to have the chance to spend time by themselves, while others find solitude painful and forever crave company? The most obvious answer would seem to be that it relates to differences in social aspects of personality, and specifically that extraverts will find solitude painful while introverts will enjoy their own company more than anyone else’s. However, a new paper, published as a pre-print at PsyArXiv (not yet peer-reviewed), and involving three diary studies with hundreds of undergrad volunteers, suggests the truth is more complicated.
In fact, there was no evidence that introverts enjoyed solitude more than extraverts. Rather, the most important trait related to liking one’s own company was having strong “dispositional autonomy”. This is a concept from self-determination theory and the researchers, led by Thuy-vy T. Nguyen at the University of Rochester, said that people strong in this trait have alignment between their behaviour, values and interests, are “resistant to pressure from others”, and “are interested in learning more about their personal experiences and emotions”. High scorers in autonomy enjoyed solitude more than others and sought it out for its own sake.
Being rich(er) may not guarantee happiness, as shown by ample evidence from the social sciences, but there are ways of spending money that will make you happier than others. Recent research has uncovered the “experiential advantage”: greater happiness from spending money on experiences (holidays, meals, theatre tickets) instead of material things (gadgets, clothes, jewellery). This could be for a number of reasons, such as experiences being more closely aligned with our values and being less likely to produce rumination and regret. There are exceptions to this rule, of course. Studies have found that personality traits can influence whether experiences or things make a person happiest; for example, introverts are made much happier by spending vouchers in a bookshop than a bar.
Another likely exception, that hasn’t previously been studied, is how social class, and specifically access to resources, affects this experiential advantage. Indeed, most research in this area has been performed with college students, who are typically more affluent than the general population, and there are reasons to believe that those who are less well-off might prefer material goods. For them, buying things as opposed to experiences could be more practical: they last longer, can be used multiple times and potentially resold in the future. To put this reasoning to the test, a recent paper in Psychological Science investigated whether the experiential advantage is diminished or absent for people who can afford very little compared with those who can afford a lot.
For decades, personality psychologists have noticed a striking, consistent pattern: extraverts are happier more of the time than introverts. For anyone interested in promoting wellbeing, this has raised the question of whether it might be beneficial to encourage people to act more extraverted. Evidence to date has suggested it might.
For example, regardless of their usual disposition, people tend to report feeling happier and more authentic whenever they are behaving more like an extravert (that is, more sociable, active and assertive). That’s a mere correlation that could be interpreted in different ways. But lab studies have similarly found that prompting people, including introverts, to act more like an extravert makes them feel happier and truer to themselves.
Before we all start doing our best extravert impressions in pursuit of greater happiness, though, a team of researchers led by Rowan Jacques-Hamilton at the University of Melbourne urge caution, writing in their new pre-print at PsyArXiv :
“Until we have a well-rounded understanding of both the positive and negative consequences of extraverted behaviour, advocating any real-world applications of acting extraverted could be premature and potentially hazardous.”
To help, these researchers have conducted the first ever randomised-controlled trial of an “act more extraverted” intervention, and unlike in previous research, they looked beyond the lab at the positive and negative effects of such an intervention on people’s feelings in daily life.
“Update: On Twitter, some researchers argued, reasonably in my view, that I wasn’t quite sceptical enough in relating these findings. See the update at the end of this post for more details.”
If you wanted a poster child for the replication crisis and the controversy it has unleashed within the field of psychology, it would be hard to do much better than Fritz Strack’s findings. In 1988, the German psychologist and his colleagues published research that appeared to show that if your mouth is forced into a smile, you become a bit happier, and if it’s forced into a frown, you become a bit sadder. He pulled this off by asking volunteers to view a set of cartoons (paper ones, not animated) while holding a pen in their mouth, either with their teeth (forcing their mouth into a smile), or with their lips (forcing a frown), and to then use the pen in this position to rate how amused they were by the cartoons. The smilers were more amused, and the frowners less so – and best of all, they mostly didn’t discern the true purpose of the experiment, eliminating potential placebo-effect explanations.
This basic idea, that our facial expressions can feed back into our psychological state and behavior, goes back at least as far as Darwin and William James, but “facial feedback”, as it is known, had never been demonstrated in such an elegant and rigorous-seeming manner. Over time, this style of experiment was replicated and expanded upon, and soon it came to be considered a true blockbuster, so famous it found its ways into psychology textbooks, as well as popular books and articles citing it as an example of the unexpectedly subtle ways our bodies and environments can affect us psychologically. Often, facial feedback has been popularised along the lines of Maybe you can smile your way to happiness!, which added an irresistible self-help element that likely helped spread the idea. Either way, it seemed like a genuinely safe and solid psychological finding. That changed rather abruptly in 2016.
What makes for a good life? Current psychological theory highlights the importance of relationships, belonging and having a sense of purpose. Gratitude, forgiveness, generosity and self-compassion often get a mention too. According to a team of psychologists at George Mason University, there is however a glaring omission. Sex.
“In theoretical models of well-being, sex is rarely discussed and in many seminal articles, ignored,” they write in their new paper published in Emotion.
Todd Kashdan and his colleagues have attempted to correct this oversight with a three-week diary study, in which they looked at the associations between sex frequency and quality and not only positive mood, but also sense of meaning in life. “If an individual gains sexual access to a romantic partner, this should raise momentary affect … and increase one’s sense of self-worth or meaning in life,” they predicted.
We’ve all been there: feeling so grateful to a friend or colleague that we hatch the idea of sending them a thank-you message. But then we worry about how to phrase it. And then we figure it probably won’t mean much to them anyway; if anything it could all be a bit awkward. So we don’t bother.
Does this sound familiar? According to a pair of US psychologists, a common failure of perspective means that a lot of us underestimate the positive impact on others (and ourselves) of expressing gratitude, meaning that we miss out on a simple way to improve our social relations and wellbeing. Based on their series of experiments in Psychological Science, Amit Kumar at the University of Texas at Austin and Nicholas Epley at Booth School of Business at the University of Chicago conclude that “expressing gratitude might not buy everything, but it may buy more than people seem to expect”.
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?
When you’re in the middle of a gruelling long-distance run and the pain and fatigue is becoming overwhelming, an obvious strategy is to try to force the subjective experience out of your mind, for example by thinking nice thoughts or focusing on the environment around you. The trouble is, as the physical struggle intensifies, the distraction strategy becomes harder and harder to pull off. According to a new paper in Motivation and Emotion, an alternative approach that holds promise is to practice “cognitive reappraisal” – don’t ignore the sensations as such, but try to view them in a dispassionate way, as if you are a scientist studying running or a journalist reporting on the experience.
From You’ve Lost that Lovin’ Feeling to Nothing Compares 2 U, there’s no shortage of songs about heartbreak. None, I suspect, contains the line, “Now it’s time to give negative reappraisal a go.” But whether you’ve just been dumped or you’ve done the dumping, if you’re still in love with your ex, this could be your best strategy for falling out of love and moving on, according to a new paper published in the Journal of Experimental Psychology.
“Romantic break-ups can have serious consequences including insomnia, reduced immune function, broken heart syndrome, depression and suicide,” note the authors, Sandra Langeslag and Michelle Sanchez at the University of Missouri, St Louis. Strategies that help people to fall out of love could relieve the agony of unrequited love or make it easier to get out of a dysfunctional relationship.
