There Is Limited Evidence To Support The Widely Held Belief That Psychotherapy Changes The Body As Well As The Mind

Looking at the latest epidemiological data, it could be argued that we are in the midst of a pandemic of mental illness, of dimensions never before seen in human history. The WHO estimates that over 350 million people around the world are presently suffering from depression, which constitutes almost 5-6 per cent of the population. At its extreme, depression may lead to suicide, by which it is estimated that around 1 million people die every year. And the numbers continue growing. Faced with this rising tide of illness, it is impossible to overestimate the importance of hard facts and data indicating the paths researchers and clinicians may follow in search of ways to help. Sometimes, as suggested by a meta-analysis of 50 years of studies on indicators that help predict suicide attempts, we are entirely helpless. In other cases, like with the recent meta-analysis of the neural correlates of the changes brought about by psychotherapy in depressed brains, study results do bring us hope.

The results of the first systematic review and meta-analysis of biological markers evaluated in randomized trials of psychological treatments for depression in Neuroscience and Biobehavioral Reviews are another attempt at understanding methods of treating this terrifying illness. The authors – Ioana A. Cristea, Eirini Karyotaki, Steven D. Hollon, Pim Cuijpers and Claudio Gentili – quite rightly point out that understanding how psychological interventions impact or are impacted by biological variables has important implications. For many people, their depression co-occurs with a bodily illness, such as cancer, diabetes, heart disease, and immune system and neurological disorders, and at times is a consequence of that illness. Although we still know little about the reciprocal cause-and-effect mechanisms between psychic and somatic symptoms, some studies have suggested that psychological interventions not only change mood, but also normalise the functioning of the autonomic nervous system, with a therapeutic effect on physical conditions, such as heart disease. But is this really true?

Are Bronze Medallists Really Happier Than Silver Medallists? New Insights From The 2016 Olympics

By guest blogger Bradley Busch

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.

Are Female And Male Brains Fundamentally Different? An Expert Pours Cold Water On Recent Claims That A Brain-Scan Study of Foetuses Proves They Are

By guest blogger Gina Rippon

In case you hadn’t noticed, there is an ongoing debate about the existence of differences between women’s and men’s brains, and the extent to which these might be linked to biological or to cultural factors. In this debate, a real game-changer of a study would involve the identification of clear-cut sex differences in foetal brains: that is, in brains that have not yet been exposed to all the different expectations and experiences that the world might offer. A recent open-access study published in Developmental Cognitive Neuroscience by Muriah Wheelock at the University of Washington and her colleagues, including senior researcher Moriah Thomason at New York University School of Medicine, claims to have done just that, hailed by the researchers themselves as “confirmation that sexual dimorphism in functional brain systems emerges during human gestation” and in various ways by the popular press as, for example, The Times of London’s headline: “Proof at last: women and men are born to be different”.

Does this study live up to the claims made by its authors and, more excitedly, those passing the message on? I think not.

Your Romantic Partner Is Probably Less Intelligent Than You Think, Suggests New Study

By guest blogger David Robson

It’s now well known that many of us over-estimate our own brainpower. In one study, more than 90 per cent of US college professors famously claimed to be better than average at teaching, for instance – which would be highly unlikely. Our egos blind us to our own flaws.

But do we have an even more inflated view of our nearest and dearest? It seems we do – that’s the conclusion of a new paper published in Intelligence journal, which has shown that we consistently view our romantic partners as being much smarter than they really are.

What Counts As Altruism? People Judge Good Acts Harshly When They Are Performed For Selfish Ends

People judge an ostensibly prosocial act, like raising money in a charity run, as less altruistic than neutral acts, if it’s done to feel good or impress others (or for other selfish motives)

By guest blogger Rhiannon Willmot

Philosophers have long debated what constitutes genuine altruism. Some have argued that any acts, no matter however charitable, that benefit both the actor as well as the recipient, are altruistically “impure”, and thus can’t qualify as genuinely selfless. For example, volunteering at a soup kitchen would no longer be considered altruistic if we received a hot meal in return for our efforts.

However, other scholars have argued that the act remains altruistic if the benefits of prosocial behaviour are an unintended consequence. From this perspective, if the meal is unexpected, our actions are still deemed selfless.

For their recent paper in the Journal of Experimental Social Psychology Ryan Carlson and Jamil Zaki have shed light on these questions by investigating what the general population thinks of different prosocial acts, depending on their motives and consequences.

Understanding popular perceptions of prosocial behavior can not only help resolve the altruism debate, but also provide information about how our behaviour might be viewed by others, and whether our personal opinions on selflessness match up with the general belief. For example, why might we perceive the supposedly altruistic behaviour of a public figure differently to our friends, and is social media really the right place to publicise prosocial acts?

Participants In This Study Successfully Down-regulated Their Amygdala Activity With The Help Of Neurofeedback

By guest blogger Eleanor Morgan

Interventions like cognitive behavioural therapy help people better control their emotions by teaching them new ways of thinking. A recent study published in NeuroImage suggests this approach could be augmented by using “neurofeedback” to help regulate activity in a key brain structure – the amygdala.

Are Criminal Profilers “Any Better Than A Bartender?” Not Necessarily, Suggests Review Of 40 Years Of Relevant Research

By guest blogger Tomasz Witkowski

The profession of “criminal profiler” is one shrouded in secrecy, even giving off a hint of danger. Yet when the American psychiatrist James A. Brussel began profiling a particular suspect in the 1950s, law enforcement officers were not entirely inclined to trust him. However, it turned out Brussel accurately defined the suspect’s height, clothing and even religion. This spectacular success was the beginning of the profession of the profiler. The FBI formed its Behavioral Science Unit in 1974 to study serial predators. Since then, the art and craft of criminal profiling have become the subject of numerous books, TV shows and iconic films such as The Silence of the Lambs. Criminal profilers are not, however, just characters created to make interesting films and books – in the real world the accuracy of their expert opinions is often key to protecting the safety and lives of others.

Can we say, after the passage of 40 years since the job of offender profiling (OP) was established, that this profession is a craft worthy of trust, one whose practitioners make use of tried and tested tools, or rather would it be more accurate to describe it as an art-form grounded in intuition that supplies us with foggy, uncertain predictions? Answers to these questions are given by Bryanna Fox from the University of South Florida and David P. Farrington from the University of Cambridge in the December edition of Psychological Bulletin, where they present a systematic review and meta-analysis of 426 publications on OP from 1976 through 2016.

The Mental Snag That Makes It Seem Like Food Is Everywhere, Especially If You’re Overweight

By guest blogger Stacy Lu

If you’re planning to take off weight in the new year and it suddenly seems like food is everywhere – and is especially enticing – that’s probably your mind playing a particularly unhelpful trick on you. Thinking about food, even in terms of trying to avoid it, can actually make it more likely that you’ll notice food in your environment, especially if you’re already overweight or obese.

That’s according to a recent study in the International Journal of Obesity that compared how overweight and healthy weight people pay attention to food. Food cues – sights, smells, advertisements and social contexts like parties – are everywhere these days, so understanding why some people find it harder to ignore them could be key to designing weight loss programmes.

Psychology research is still fixated on a tiny fraction of humans – here’s how to fix that

Nearly 95 per cent of participant samples in a leading psychology journal were from Western countries

By guest blogger Jesse Singal

For a long time, some psychologists have understood that their field has an issue with WEIRDness. That is, psychology experiments disproportionately involve participants who are Western, Educated, and hail from Industrialised, Rich Democracies, which means many findings may not generalise to other populations, such as, say, rural Samoan villagers.

In a new paper in PNAS, a team of researchers led by Mostafa Salari Rad decided to zoom in on a leading psychology journal to better understand the field’s WEIRD problem, evaluate whether things are improving, and come up with some possible changes in practice that could help spur things along.

Psychology’s favourite tool for measuring implicit bias is still mired in controversy

A new review aims to move on from past controversies surrounding the implicit association test, but experts can’t even agree on what they’re arguing about

By guest blogger Jesse Singal

It has been a long and bumpy road for the implicit association test (IAT), the reaction-time-based psychological instrument whose co-creators, Mahzarin Banaji and Anthony Greenwald — among others in their orbit — claimed measures test-takers’ levels of unconscious social biases and their propensity to act in a biased and discriminatory manner, be that via racism, sexism, ageism, or some other category, depending on the context. The test’s advocates claimed this was a revelatory development, not least because the IAT supposedly measures aspects of an individual’s bias even beyond what that individual was consciously aware of themselves.

As I explained in a lengthy feature published on New York Magazine’s website last year, many doubts have emerged about these claims, ranging from the question of what the IAT is really measuring (as in, can a reaction-time difference measured in milliseconds really be considered, on its face, evidence of real-world-relevant bias?) to the algorithms used to generate scores to, perhaps most importantly (given that the IAT has become a mainstay of a wide variety of diversity training and educational programmes), whether the test really does predict real-world behaviour.

On that last key point, there is surprising agreement. In 2015 Greenwald, Banaji, and their coauthor Brian Nosek stated that the psychometric issues associated with various IATs “render them problematic to use to classify persons as likely to engage in discrimination”. Indeed, these days IAT evangelist and critic alike mostly agree that the test is too noisy to usefully and accurately gauge people’s likelihood of engaging in discrimination — a finding supported by a series of meta-analyses showing unimpressive correlations between IAT scores and behavioral outcomes (mostly in labs). Race IAT scores appear to account for only about 1 per cent of the variance in measured behavioural outcomes, reports an important meta-analysis available in preprint, co-authored by Nosek. (That meta-analysis also looked at IAT-based interventions, finding that while implicit bias as measured by the IAT “is malleable… changing implicit bias does not necessarily lead to changes in explicit bias or behavior.”)

So where does this leave the IAT? In a new paper in Current Directions in Psychological Science called “The IAT Is Dead, Long Live The Iat: Context-Sensitive Measures of Implicit Attitudes Are Indispensable to Social and Political Psychology”, John Jost, a social psychologist at New York University and a leading IAT researcher, seeks to draw a clear line between the “dead” diagnostic-version of the IAT, and what he sees as the test’s real-world version – a sensitive, context-specific measure that shouldn’t be used for diagnostic purposes, but which has potential in various research and educational contexts.

Does this represent a constructive manifesto for the future of this controversial psychological tool? Unfortunately, I don’t think it does – rather, it contains many confusions, false claims, and strawman arguments (as well as a misrepresentation of my own work). Perhaps most frustrating, Jost joins a lengthening line of IAT researchers who, when faced with the fact that the IAT appears to have been overhyped for a long time by its creators, most enthusiastic proponents, and by journalists, responds with an endless variety of counterclaims that don’t quite address the core issue itself, or which pretend those initial claims were never made in the first place.
