The placebo effect is a curious phenomenon. A wealth of literature has shown that inert treatments can not only produce medical benefits like pain relief, but also have cognitive effects like boosting creativity and learning. And while many of those studies involve misleading people into thinking that they are receiving an effective intervention, a new study in Scientific Reports shows that this deception is not always necessary. Researchers have found that taking a placebo can reduce people’s anxiety before a test — even when they know they are taking an inactive pill.
Researchers have long known that people who are more extraverted tend to be happier, leading some to suggest that encouraging extraverted behaviour could improve wellbeing. Last year we reported on the first trial of such an intervention, which found that acting like an extravert for a week led to an increase in positive emotions in certain people. Now a second study appears to have replicated that result — and shown that behaving like an introvert may also reduce wellbeing.
At 8:07am on a Saturday morning in early 2018, phones throughout Hawaii buzzed with a distressing message. “Ballistic missile threat inbound to Hawaii. Seek immediate shelter,” it read. “This is not a drill.” Similar warnings interrupted television and radio transmissions. And until a follow-up message 38 minutes later clarified that it had been a false alarm, many residents were left expecting the worst.
But according to a new study published in American Psychologist, the toll on Hawaii residents lasted much longer than those terrifying minutes. Researchers analysing the kinds of words tweeted before and after the false alarm have found that anxiety seemed to be heightened for days — particularly among those who appeared the least anxious to begin with.
The first step to dealing with a negative emotion is to identify it. If you’re feeling irritated, restless or guilty, the most effective way to start feeling better will be different in each case. The trouble is, if your sense of your own emotions is not that fine-grained – if you feel just “bad” or “upset” – you may struggle to identify the cause of your distress, making it tricky to self-regulate your emotions.
Plenty of studies have linked a poor ability to differentiate between negative emotions (known as “low Negative Emotion Differentiation” or “low NED” for short) to depression. But this work has mostly been conducted at a single point in time (i.e. having a “cross-sectional” design), making it impossible to tell whether difficulties with emotional differentiation cause depression or vice versa. The research has also overwhelmingly involved adults, and yet it is adolescence that is most marked by low NED (even more than in early childhood) and depression. This mismatch in the literature motivated Lisa Starr at the University of Rochester and her colleagues to conduct a longitudinal study on adolescents, published recently in Emotion. They looked not only at teenagers’ NED and depressive symptoms over time, but also their experience of minor daily hassles and more serious stressful life events.
You may be best advised not to read this article late at night or before you eat. Psychologists at the National Institute of Mental Health and Charles University in the Czech Republic have surveyed a large sample of non-clinical volunteers to gauge their reaction to 24 creatures that are commonly the source of specific animal phobias.
The results, published in the British Journal of Psychology, not only contribute to our understanding of animal phobias, but could prove incredibly useful to horror writers. Among the key findings is that spiders were unique in being both intensely fear- and disgust-inducing in equal measure. The researchers said this may be due to their mix of disgusting properties – including their “quirky ‘too-many-legs’ body plan” – combined with the fact they are “…omnipresent in our homes, often lurking in the hidden dark places and capable of fast unpredictable movement.” In other words, the intense fear arises in part from the prospect of coming into physical contact with a creature perceived by many to be revolting.
It’s well-established in psychology that intense emotion and physiological arousal interfere with people’s ability to think straight. Most theories explain this in terms of anxiety consuming mental resources and focusing attention on potential threats. Although it’s tricky to study this topic in the psych lab, a handful of field studies involving parachutists and emergency simulations have largely supported this picture. However, a team at the Autonomous University of Barcelona believe that not enough consideration has so far been given to what they call the “valence” of intense situations – whether or not the person sees the intense experience as positive or negative. To find out whether this makes a difference, Judit Castellà and her colleagues tested dozens of bungee jumpers (most of them first-timers) three times: 30 minutes before a 15M free fall jump; immediately afterwards; and again eight minutes after that.
The surprising findings, reported in Cognition and Emotion, suggest that when an intensely arousing experience is perceived positively, it may actually enhance cognition rather than be impairing. “Although we expected some degree of moderation, that is, an attenuation of the negative impact of high arousal reported in the literature, we did not predict an actual improvement or a total lack of impairment,” the researchers said.
During major bouts of anger or fear, people can end up taking extreme and sometimes violent actions. But they often say that, in the moment, they didn’t feel responsible for those actions – they “lost control” or “saw red”. In the UK, under certain circumstances, a person accused of murder can even claim that this “loss of control” led to them killing their victim. If successful, this defence can reduce charges to manslaughter.
Now the first study of its kind suggests that there is some truth to these claims. Participants put into a fearful or angry state really do seem to have a reduced sense of agency, according to a paper published recently in Experimental Brain Research, raising questions about the accountability of people going through extreme emotions.
To win a medal of any kind at the Olympic Games takes years of training, hard work and sacrifice. Standing on an Olympic podium is widely regarded as the pinnacle of an athlete’s career. Nonetheless, only one athlete can win gold, leaving the two runner-up medallists to ponder what might have been. Intriguingly a seminal study from the 1992 Olympic Games suggested that this counterfactual thinking was especially painful for silver medallists, who appeared visibly less happy than bronze medallists. The researchers speculated that this may have been because of the different counterfactual thinking they engaged in, with bronze medallists being happy that they didn’t come fourth while silver medallists felt sad that they didn’t win gold.
However, subsequent research based on the 2000 Olympic Games did not replicate this finding: this time silver medallists were found to be happier than bronze medallists. To further muddy the waters, a study from the 2004 Games was consistent with the seminal research, finding that straight after competition, gold and bronze medallists were more likely to smile than silver medallists, with these smiles being larger and more intense.
Now further insight into the psychology of coming second or third comes via Mark Allen, Sarah Knipler and Amy Chan of the University of Wollongong, who have released their findings based on the 2016 Olympic Games. These latest results, published in Journal of Sports Sciences, again challenge that initial eye-grabbing result that suggested bronze medallists are happier than silver medallists, but they support the idea that the nature of counterfactual thinking differs depending on whether athletes come second or third.
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.
