Spending time alone is a virtually inevitable part of daily life that can promote or undermine well-being.
Here, we explore how the language used to describe time alone—such as “me-time” “solitude,” or “isolation”—influences how it is perceived and experienced […]
linguistic framing affected what people thought about, but not what they did, while alone […]
simple linguistic shifts may enhance subjective experiences of time alone
We do not have a veridical representation of our body in our mind. For instance, tactile distances of equal measure along the medial-lateral axis of our limbs are generally perceived as larger than those running along the proximal-distal axis. This anisotropy in tactile distances reflects distortions in body-shape representation, such that the body parts are perceived as wider than they are. While the origin of such anisotropy remains unknown, it has been suggested that visual experience could partially play a role in its manifestation.
To causally test the role of visual experience on body shape representation, we investigated tactile distance perception in sighted and early blind individuals […] Overestimation of distances in the medial-lateral over proximal-distal body axes were found in both sighted and blind people, but the magnitude of the anisotropy was significantly reduced in the forearms of blind people.
We conclude that tactile distance perception is mediated by similar mechanisms in both sighted and blind people, but that visual experience can modulate the tactile distance anisotropy.
At the root of post-traumatic stress disorder, or PTSD, is a memory that cannot be controlled. It may intrude on everyday activity, thrusting a person into the middle of a horrifying event, or surface as night terrors or flashbacks. Decades of treatment of military veterans and sexual assault survivors have left little doubt that traumatic memories function differently from other memories. […]
The people listening to the sad memories, which often involved the death of a family member, showed consistently high engagement of the hippocampus, part of the brain that organizes and contextualizes memories. When the same people listened to their traumatic memories — of sexual assaults, fires, school shootings and terrorist attacks — the hippocampus was not involved. […]
“traumatic memories are not experienced as memories as such,” but as “fragments of prior events, subjugating the present moment.” The traumatic memories appeared to engage a different area of the brain — the posterior cingulate cortex, or P.C.C., which is usually involved in internally directed thought, like introspection or daydreaming. The more severe the person’s PTSD symptoms were, the more activity appeared in the P.C.C. What is striking about this finding is that the P.C.C. is not known as a memory region, but one that is engaged with “processing of internal experience”

Unrealistic optimism or optimism bias—the tendency for individuals to overestimate the chance of favorable outcomes occurring and underestimate the chance of bad —has been found to be one of the most pervasive human traits across many domains. For instance, research has shown that individuals tend to underestimate the likelihood of developing a drinking problem or getting divorced and to overestimate their future earnings and how long they are going to live. Our established tendency toward unrealistic optimism poses an evolutionary puzzle as normative models of human judgment, like expected utility theory, suggest unbiased assessments of probabilities are advantageous. Like any other judgmental bias, optimism bias distorts the decision-making process, leading to systematic decision errors, increased rash and risky behavior and a failure to take precautionary measures. […]
There are reasons for expecting that the optimism bias may be associated with cognitive ability. Supportive empirical evidence for this framework comes from the experimental literature on cognitive ability and judgmental biases. For instance, intelligence has been found to lower one’s susceptibility to hindsight bias, overconfidence, framing, and the sunk cost fallacy. […]
we used an unbalanced panel of 36,312 respondents […]
The findings we present provide evidence that forecasting accuracy is linked to cognitive ability. Specifically, we find that higher cognitive ability is associated with a higher incidence of realism and pessimism in beliefs and a lower incidence of unrealistic optimism.
Taken together, our results lead us to conclude that the rash and risky behaviors associated with excessive optimism may be a side product of the true driver, low cognitive ability.

A cornerstone of cognitive science is that mental systems are limited: There is a maximum amount of information they can process or store, beyond which performance breaks down. Yet so far the study of such limits has been focused on core systems like attention and memory. Here we explore the limit of self-representation, the ability to represent someone or something as you. […]
results are consistent with the view that the mind employs a cognitive architecture that can represent at most one self at a time, and which serially switches out the items it represents. […]
The self-representational limit of one item at a time differs markedly from known limits on other systems, like attention and short-term memory. The number of items we can both track and remember in short-term memory is greater than one, and somewhat flexible depending on the nature of the stimuli and their relations. For instance, people can track more items if they are evenly spaced out on the display rather than clumped together (Alvarez & Franconeri, 2007), remember more items if they are less complex (e.g., simple colors rather than shaded cubes) (Alvarez & Cavanagh, 2004), and both track and remember more items if they span the visual hemifields rather than occur within a single visual hemifield (Alvarez & Cavanagh, 2005; Strong & Alvarez, 2020). Self-representation appears to have a limit that is more severe and inflexible.
Adult individuals frequently face difficulties in attracting and keeping mates, which is an important driver of singlehood.
In the current research, we investigated the mating performance (i.e., how well people do in attracting and retaining intimate partners) and singlehood status in 14 different countries, namely Austria, Brazil, China, Greece, Hungary, Italy, Japan, Peru, Poland, Russia, Spain, Turkey, the UK, and Ukraine (N = 7,181).
We found that poor mating performance was in high occurrence, with about one in four participants scoring low in this dimension, and more than 57% facing difficulties in starting and/or keeping a relationship.
Men and women did not differ in their mating performance scores, but there was a small yet significant effect of age, with older participants indicating higher mating performance.

Previous studies on aesthetic chills (i.e., psychogenic shivers) demonstrate their positive effects on stress, pleasure, and social cognition. We tested whether we could artificially enhance this emotion and its downstream effects by intervening on its somatic markers using wearable technology.
Evaluating other people’s sincerity is a ubiquitous and important part of social interactions.
Fourteen experiments show that response speed is an important cue on which people base their sincerity inferences. Specifically, people systematically judged slower responses as less sincere […].
the present study highlights the potential effects that may be observed in judicial settings, since the response speed of innocent suspects may mislead people to judge them as insincere and hence guilty.

What if a pill can change your politics or religious reliefs? […] Psychotherapy assisted by psilocybin, the psychedelic compound in “magic mushrooms,” seems to be remarkably effective in treating a wide range of psychopathologies, but also causes a raft of unusual nonclinical changes not seen elsewhere in medicine. […]
Although its precise therapeutic mechanisms remain unclear, clinically relevant doses of psilocybin can induce powerful mystical experiences more commonly associated with extended periods of fasting, prayer or meditation. Arguably, then, it is unsurprising that it can generate long-lasting changes in patients: studies report increased prosociality and aesthetic appreciation, plus robust shifts in personality, values and attitudes to life, even leading some atheists to find God. What’s more, these experiences appear to be a feature, rather than a bug, of psilocybin-assisted psychotherapy, with the intensity of the mystical experience correlating with the extent of clinical benefit.
Faces provide not only cues to an individual’s identity, age, gender, and ethnicity but also insight into their mental states. The aim was to investigate the temporal aspects of processing of facial expressions of complex mental states for very short presentation times ranging from 12.5 to 100 ms. […]
Results show that participants are able to recognise very subtle differences between facial expressions; performance is better than chance, even for the shortest presentation time. Importantly, we show for the first time that observers can recognise these expressions based on information contained in the eye region only.
Self-promotion is common in everyday life. Yet, across 8 studies (N = 1,687) examining a broad range of personal and professional successes, we find that individuals often hide their successes from others and that such hiding has relational costs. […]
Whereas previous research highlights the negative consequences of sharing one’s accomplishments with others, we find that sharing is superior to hiding for maintaining one’s relationships.

signs of dishonesty decreased trust but only in those who had not previously built a good reputation as honest partners.
On the contrary, those who could establish a good reputation were trusted even when they were no longer trustworthy, suggesting that participants could not successfully track changes in trustworthiness of those with an established good reputation.

A number of studies – including our own – find a mid-life dip in well-being. […] The effects of the mid-life dip are comparable to major life events like losing a spouse, losing a job or getting cancer. They are clearly not inconsequential.
Emerging findings suggest that decision-making competence may tap not only into fluid intelligence but also into motivation, emotion regulation, and experience (or crystallized intelligence). Although fluid intelligence tends to decline with age, older adults may be able to maintain decision-making competence by leveraging age-related improvements in these other skills.

David Silver [the creator of AlphaZero] hasn’t answered my question about whether machines can set up their own goals. He talks about subgoals, but that’s not the same. That’s a certain gap in his definition of intelligence. We set up goals and look for ways to achieve them. A machine can only do the second part.
So far, we see very little evidence that machines can actually operate outside of these terms, which is clearly a sign of human intelligence. Let’s say you accumulated knowledge in one game. Can it transfer this knowledge to another game, which might be similar but not the same? Humans can. With computers, in most cases you have to start from scratch.

Curiosity - the drive for information - is often perceived as a dangerous trait. This is exacerbated by the perception that when something is forbidden, curiosity towards it increases. […]
This research demonstrated the so-called “forbidden fruit effect”, in which unavailable options elicit curiosity – the desire to know more – even when people were completely aware that the forbidden option did not differ from other options in terms of expected outcome, uncertainty (hidden values), and visual salience.
Even though it may come naturally, griping isn’t necessarily always a good thing. Ruminating on negative feelings, and reinforcing them through constant discussion with other people, can lead to catastrophizing, which “is something that can contribute to depression” […]
This can happen because “the more you do something, the more entrenched that path becomes in your brain and the more you continue to do it” […]
Constantly complaining can be an easy way to frustrate our confidantes, but there is research that shows it can also be a useful tool in bonding and helping us process emotions like stress and frustration.
“In short: Yes, it’s good to complain, yes, it’s bad to complain, and yes, there’s a right way to do it” […] The trick to doing it right starts with understanding how the word “complaining” is often misused to describe a variety of behaviors, with some being more harmful or helpful than others. […] there are roughly three categories: venting, problem solving and ruminating, otherwise known as dwelling. […]
Life isn’t perfect. That’s why expressing negative feelings is not only normal, but also healthy, Dr. Kowalski said, adding that the unrealistic expectation that we should always be happy can make us feel worse. […] Inhibiting the disclosure of our dissatisfaction “can produce a negative effect,” she said, because it not only stops us from naming our problem but also prevents us from getting to the root of it.
That’s why “complaining is, ideally, totally solutions focused,” Ms. Gilbertson said. Though venting is not as focused on solving problems, “there are also really positive benefits,” Dr. Grice said, because it allows us “to get things out in the open and get our feelings heard so they don’t build up and cause stress.” […]
You want to avoid what Dr. Grice calls wearing “muddy glasses,” where no matter what’s going on you always find something to complain about. The same goes with rehashing a problem over and over again, whether with friends or in the echo chamber of the internet.
The latest research, published on Friday by two psychology professors, combs through about 40 studies that have examined the link between social media use and both depression and anxiety among adolescents. That link, according to the professors, is small and inconsistent. […]
In most cases, [most researchers] say, the phone is just a mirror that reveals the problems a child would have even without the phone. […]
“The current dominant discourse around phones and well-being is a lot of hype and a lot of fear,” Mr. Hancock said. “But if you compare the effects of your phone to eating properly or sleeping or smoking, it’s not even close.”
Mr. Hancock’s analysis of about 226 studies on the well-being of phone users concluded that “when you look at all these different kinds of well-being, the net effect size is essentially zero.”
He had diabetes, and he had signed up for a study to see if taking a “statin” – a kind of cholesterol-lowering drug – might help. So far, so normal.
But soon after he began the treatment, his wife began to notice a sinister transformation. A previously reasonable man, he became explosively angry and – out of nowhere – developed a tendency for road rage. During one memorable episode, he warned his family to keep away, lest he put them in hospital. […]
In 2018, a study uncovered the same effect in fish. Giving statins to Nile tilapia made them more confrontational and – crucially – altered the levels of serotonin in their brains. This suggests that the mechanism that links cholesterol and violence may have been around for millions of years.
Golomb remains convinced that lower cholesterol, and, by extension, statins, can cause behavioural changes in both men and women, though the strength of the effect varies drastically from person to person. […]
The world is in the midst of a crisis of over-medication, with the US alone buying up 49,000 tonnes of paracetamol every year – equivalent to about 298 paracetamol tablets per person. [..]
Mischkowski’s own research has uncovered a sinister side-effect of paracetamol. For a long time, scientists have known that the drug blunts physical pain by reducing activity in certain brain areas, such as the insular cortex, which plays an important role in our emotions. These areas are involved in our experience of social pain, too – and intriguingly, paracetamol can make us feel better after a rejection.
And recent research has revealed that this patch of cerebral real-estate is more crowded than anyone previously thought, because it turns out the brain’s pain centres also share their home with empathy. […] results revealed that paracetamol significantly reduces our ability to feel positive empathy – a result with implications for how the drug is shaping the social relationships of millions of people every day. […] Technically, paracetamol isn’t changing our personalities, because the effects only last a few hours and few of us take it continuously.
