No grief for clichés

Time magazine has a fantastic article that tackles common myths about the psychology of grief and the experience of losing a loved one.

We’ve discussed previously how many of the grief clichés (there are specific stages, you have to ‘let it out’ etc) have already been shown to be false but this Time piece goes in greater detail and traces the origin of these myths in the work of Elisabeth Kübler-Ross.

Kübler-Ross was an important pioneer in understanding grief, but she was basing her theories on very little evidence and we now know from more rigorous studies that many of her conclusions were wrong.

Although Kübler-Ross modified her position with regard to the famous ‘stage model’ of grief, where we supposedly pass through distinct stages – saying that they were never intended to be one after the other, later empirical studies have found little evidence for any consistent stages.

One of the reasons that the five stages became so popular is that they make intuitive sense. “Any natural, normal human being, when faced with any kind of loss, will go from shock all the way through acceptance,” Kübler-Ross said in an interview published in 1981.

Two decades later, a group of researchers at Yale decided to test whether the stages do, in fact, reflect the experience of grief. The researchers used newspaper ads and referrals to recruit 233 recently bereaved people, who were assessed for “grief indicators” in an initial interview and then in a follow-up some months later. In the Kübler-Ross model, acceptance, which she defined as recognizing that your loved one is permanently gone, is the final stage.

But the resulting study, published in the Journal of the American Medical Association in 2007, found that most respondents accepted the death of a loved one from the very beginning. On top of that, participants reported feeling more yearning for their loved one than either anger or depression, perhaps the two cornerstone stages in the Kübler-Ross model.

The article tackles many more common beliefs about suffering loss and is a highly recommended look into what is often thought to be ‘common knowledge’.

The psychology of the 7 deadly sins

The Psychologist has an engrossing article on the psychology behind the ‘7 Deadly Sins’ and how they relate to modern life.

The piece is full of fascinating and counter-intuitive snapshots from the science of social emotions. For example:

Whereas the success and status of others can provoke envy, pride is what we feel when the success and status are our own. Pride, like envy is a human universal, and is another of the sins considered by psychology to be an emotion. Darwin categorised it alongside states such as vanity and suspicion as a ‘complex emotion’. He also anticipated contemporary research showing that the expression of pride – head held high, arms raised – is recognised universally across cultures and by children as young as four.

In 2008 Jessica Tracy at the University of British Columbia and David Matsumoto at San Francisco State University studied congenitally blind Olympic judo competitors and found that they too showed pride in this way, even though they can’t ever have seen a pride display by anyone else.

The BPS Research Digest blog will also be running a ‘sin week’ in the coming week so keep your eye’s peeled for more bad behaviour.

A culture shock in brain ethics

Dana has an eye-opening article on the challenges of doing brain research in cultures that don’t share the same assumptions about science and human nature.

There are several sections of the article which turn our research assumptions on their head, owing to the fact that some common principles of ethical research turn out to be based on quite a narrow view of human values.

The idea that donating tissue is simply a matter of individual choice is not a belief held by many communities who believe that all people are interconnected – making individual donations a group decision.

The article touches on an example from the Havasupai people and a similar situation was discussed in an All in the Mind interview with a Maori neuroscientist.

However, I was particularly struck by this part on confidentiality which is often assumed to be the bedrock of human research.

Confidentiality poses another ethical challenge to researchers working with indigenous peoples. Participants in academic studies are invariably anonymous, but in many Native cultures, not identifying oneself, one’s family, and one’s homeland is unacceptable. Anonymity, they believe, undermines the cultural fabric of the community, and is akin to stripping its members of their traditions and beliefs.

Painful relief for a guilty act

The idea that physical pain can alleviate guilt has a long heritage but a new study just published in Psychological Science has produced evidence that helps confirm this long-held belief.

The experiment, led by psychologist Brock Bastian, asked people to recall a time when they had behaved unacceptably and then rate their current level of guilt as they thought back.

The participants were then asked to do a dexterity task with one hand while either keeping their other hand either in a painful bucket of cold water or in a bucket of lukewarm water.

Participants who wrote about an unethical behavior not only held their hands in ice water longer but also rated the experience as more painful than did participants who wrote about an everyday interaction. Critically, experiencing pain reduced people’s feelings of guilt, and the effect of the painful task on ratings of guilt was greater than the effect of a similar but nonpainful task.

Pain has traditionally been understood as purely physical in nature, but it is more accurate to describe it as the intersection of body, mind, and culture. People give meaning to pain, and we argue that people interpret pain within a judicial model of pain as punishment. Our results suggest that the experience of pain has psychological currency in rebalancing the scales of justice—an interpretation of pain that is analogous to notions of retributive justice. Interpreted in this way, pain has the capacity to resolve guilt.

The urban formula

I’ve just caught up with a wonderful New York Times article on the underlying social structure of cities and how seemingly simple mathematical formulas can describe the complexities of urban living.

Geoffrey West is an ex-particle physicist who decided to ‘solve’ cities and set about looking for mathematical laws in the seething mass of statistics generated by city life.

There is something deeply strange about thinking of the metropolis in such abstract terms. We usually describe cities, after all, as local entities defined by geography and history. New Orleans isn’t a generic place of 336,644 people. It’s the bayou and Katrina and Cajun cuisine. New York isn’t just another city. It’s a former Dutch fur-trading settlement, the center of the finance industry and home to the Yankees.

And yet, West insists, those facts are mere details, interesting anecdotes that don’t explain very much. The only way to really understand the city, West says, is to understand its deep structure, its defining patterns, which will show us whether a metropolis will flourish or fall apart. We can’t make our cities work better until we know how they work. And, West says, he knows how they work.

It’s not just about the fundamental of our most complex human societies though – the article reflects on the role of large social groups in human development and their varying forms of durability.

My description doesn’t nearly do the piece justice, however, which remains one of the most intriguing and stimulating articles I’ve ever read on the evolution of urban living.

And I’m telling you you’re dead

Two delusional patients who believed that friends and relatives had died, despite them being around to prove otherwise, are described in an amazing 2005 journal article from the International Journal of Geriatric Psychiatry.

Although the Cotard delusion is well studied in psychiatry, where patients believe themselves to be dead, the report names the novel belief that another living person has died ‘Odysseus Syndrome’ – after the Greek legend where Penelope continued to believe that Odysseus had died, even after returning home from battle.

Both case studies are quite spectacular:

An 81-year-old lady presented to psychiatric services for the first time with sudden onset of ideas that her grandson had developed grossly swollen legs, inflammation of the brain, lethargy and extreme tiredness after infection by a fly which had picked up radioactive waste in the English Channel. Despite speaking to him over the telephone, she believed that he had died.

She believed that he had no stomach or internal organs, that his eyes had been removed and replaced with glass eyes, that his brain had died and been replaced by a clock and that he had expanded to become grossly obese. She described hallucinations of police providing commentary on his actions, but no other first rank symptoms of schizophrenia. Her mood was subjectively depressed but this clearly post-dated the onset of her delusions.

The lady in question had the beliefs for five years by the time of the report, although seemed to be getting on with life despite her mortality-related convictions.

The second case describes a lady with delusions that are reported as being similarly unshakeable.

A 73-year-old lady with a 40 year history of paranoid schizophrenia presented with grossly elated mood, over-activity, over-talkativeness, distractibility and grandiose beliefs. She sought help to prevent ‘experimentation’ on her lover’s health in the flat next door. She maintained he had developed ‘The Pox’ leading to his limbs rotting away, his heart being replaced by a machine and his brain requiring removal.

She believed nonetheless that he could send messages to her via television to which she could respond by arranging candles in a certain fashion. She was observed to be hallucinating to his voice. She maintained that he had died but come back to live in her mattress in a grossly distorted form, being very much larger than he had been in real life.

The real real thing

The can on the left is an energy drink that gets its kick from real coca leaves.

It’s called Coca Sek and was created by the indigenous Páez people of Colombia, partly in protest at the association between their traditional plant and the cocaine trade, which makes the illicit drug by processing the leaves.

The indigenous people of South American have used coca for thousands of years for its mild stimulant effects. Coca Cola originally used coca leaf extract for its kick, hence the name, but now apparently only uses ‘denatured’ leaves for flavouring.

It has only been relatively recently that the plant has been of interest to narcotraffickers, leading to the stigmatisation of the plant and its use to fund violence.

In 2005, the Páez people decided they would make a series line of home products based on coca, partly as a form of income and partly as a way of rehabilitating the image of their sacred plant.

They launched the drink to much fanfare, including coverage by the LA Times, only for the Colombian government to pressure the major supermarkets to take it off their shelves in 2007 because of its association with drugs.

However, the product lines, including energy drinks and tea bags, are still available in market stalls and health food shops around the capital.

A violent reaction to sad news

I’ve written article for Slate about the Arizona shooting and why many are too quick to use “mental illness” as a catch-all explanation for violence.

I suspect we’re going to hear a great deal more about the issue in the coming weeks, and not all of it positive or well-informed.

This article looks at some of the relevant scientific evidence and some of the misconceptions that invariably arise when such tragic circumstances make headlines.

Shortly after Jared Lee Loughner had been identified as the alleged shooter of Arizona Rep. Gabrielle Giffords, online sleuths turned up pages of rambling text and videos he had created. A wave of amateur diagnoses soon followed, most of which concluded that Loughner was not so much a political extremist as a man suffering from “paranoid schizophrenia.”

For many, the investigation will stop there. No need to explore personal motives, out-of-control grievances or distorted political anger. The mere mention of mental illness is explanation enough. This presumed link between psychiatric disorders and violence has become so entrenched in the public consciousness that the entire weight of the medical evidence is unable to shift it. Severe mental illness, on its own, is not an explanation for violence, but don’t expect to hear that from the media in the coming weeks.

The new year in sex and science

Dr Petra has her traditional review of the year in sex and sex reporting and makes her predictions for the coming year.

You probably won’t find a better summary of the sex and psychology highlights from 2010, with both the highs and lows of how the media managed their restless desires.

If you read nothing else, don’t miss this paragraph, because it’s not often that sex shops, the African country of Burkina Faso, a dodgy clitoris adoption project and a flying saucer cult get mentioned in the same breath:

April also saw the bizarre case of Clitoraid unfold. What began as a request via twitter and facebook to ‘adopt a clitoris’ soon was a more complex case involving a cult, unclear activities in Burkina Faso, and the support of sex educators and a sex store. A summary of the story can be found here, here and here. Many questions about Clitoraid still remain unanswered, and have caused rifts between sex educators, activists and health/development practitioners. This bad feeling was distressing, particularly since many involved were highly respected within the field of sex education and activism – and because basic respectful approaches to international practice were ignored.

Also don’t miss Dr Petra’s look back at 2010’s predictions and her look forward to what 2011 might hold for the world of sex and science.

And if you’re made of stronger stuff than me, you might even be able to recommend the article without making the obvious ‘crystal balls’ joke.

The dynamic embrace

I’ve just found an enjoyable BBC World Service radio documentary on the relationship between tango and psychoanalysis in the Argentinian city of Buenos Aires.

Buenos Aires is the birthplace of tango and, as we’ve discussed before, has the highest ratio of psychologists to population of any place on earth.

The city has traditionally been one of the world centres for psychoanalysis and it remains a hub for theory and treatment drawn from the work of Sigmund Freud.

The BBC documentary looks at the relationship between the city’s love of therapy and one of the most psychological of dances, talking to both enthusiasts and conscientious objectors.

The psychology of shoulder-to-shoulder

The consistently sublime RadioLab has a wonderful programme on the psychology of altruism which manages to capture the psychology of supporting others in gripping stories of human interaction.

The standard view of evolution is that living things are shaped by cold-hearted competition. And there is no doubt that today’s plants and animals carry the genetic legacy of ancestors who fought fiercely to survive and reproduce. But in this hour, we wonder whether there might also be a logic behind sharing, niceness, kindness … or even, self-sacrifice.

Is altruism an aberration, or just an elaborate guise for sneaky self-interest? Do we really live in a selfish, dog-eat-dog world? Or has evolution carved out a hidden code that rewards genuine cooperation?

The programme touches on everything from the mathematics of nuclear war to the motivation for heroism and, as always, is really better experienced than described.

But even given the usual exceptional quality of RadioLab, this episode is definitely not one to miss. Fantastic stuff.

The battleground of remembering

I’ve just discovered a engrossing two-part BBC World Service documentary on ‘oral history’ and how the process of getting everyday folk to relay their memories of important event often challenges the authorised memories of official history.

The programme makes an interesting distinction between public memory, the authorised version of events; individual memory, that we each hold inside us; and collective memory, the process by which we collectively negotiate what we believed happened.

Oral history gets individuals to recount their memories of events, but focuses much more on lived experiences and opinions than names and dates, although can be unsettling to official histories when they contradict politically convenient narratives.

An informal chat about hard data

Scientific American has an excellent article on the sociology of communicating new discoveries and how the relationship between science and journalism has changed over the years.

It’s a remarkably comprehensive analysis that looks not only at science publication but how it relates to our regular patterns of social communication.

This informal style of communication has been deliberately excluded from science in recent decades through the adoption of peer-review and a uniform impersonal writing style, as a way of imbuing the process with a form of institutional trust.

According to the author, online science pioneer Bora Zivkovic, this model is now being challenged by internet science writing where trust is gained through transparency – showing your working and background through links to original source – rather than having an institutional stamp of approval.

I think he’s a little hard on traditional science journalists, but as an analysis of how trust works in science communication, and how that is being affected by the online science community, it’s an incredibly thought-provoking piece.

The plant of human puppets

I’ve made a radio programme with ABC Radio National’s All in the Mind about burundanga, a mysterious street drug used in South America which is widely believed to remove free will.

The name ‘burundanga’ is a popular term and doesn’t refer to a single thing, but its most commonly associated with the brugmansia plants.

They can incapacitate people in high enough doses owing to them being rich in a psychoactive chemical called scopolomine. Criminals spike unsuspecting members of the public and then rob or attack them.

Since living in Colombia, I’ve constantly heard people tell me that the plant removes free will – the affected people just do whatever they’re told. They become, in effect, human puppets.

To me, this always sounded unlikely, and it struck me that, if this was genuinely the case, this might be a hugely important discovery in neuroscience, because free will and agency are two of the most complex and difficult to grasp areas.

But the plant also has hundreds, and probably thousands, of years of history as a psychoactive component of the religious rituals of the indigenous people of the continent, to the point where it holds a central place in some of their founding myths.

Needless to say, the chance to wander round Colombia making a documentary about a psychoactive plant at the intersection of neuroscience, myth and criminal science was too good to miss, so I hope you enjoy the journey.

It sounds wonderful, by the way, but almost entirely due to presenter and producer Natasha Mitchell’s magic at the mixing desk when making sense of my raw materal.

I’ve also written an article about the substance, including the first attempt to use it as a ‘truth drug’ after a gruesome murder, and there’s an image gallery available too.

Cannibal cuisine

Cannibalism is a lot more common in human history than you’d guess and an intriguing article in Slate looks at the how a change in living situation might have made the temptations of the flesh all the more appealing.

The piece is by psychologist Jesse Berring who gets his teeth into the scientific debate about whether chowing down on another human may be a genuine biological adaptation, owing to the frequency with with famine-like conditions have appeared in human history.

The bottom line, says Petrinovich, is that when you’re hungry enough, ravenous really, and when all other food sources—including “inedible” things you’d rather not stomach such as shoes, shoelaces, pets, steering wheels, rawhide saddlebags, or frozen donkey brains—have been exhausted and expectations are sufficiently low, even the most recalcitrant moralist among us would shrug off the cannibalism taboo and savor the sweet meat of man … or woman, boy or girl, for that matter. It’s either that or die, and among the two choices, only one is biologically adaptive.

A behavior can be adaptive without being an inherited biological adaptation, of course. But because starvation occurred with such regularity in our ancestral past, and because the starving mind predictably relaxes its cannibalistic proscriptions, and because eating other people restores energy and sustains lives, and because the behavior is universal and proceeds algorithmically (we eat dead strangers first, then dead relatives, then live slaves, then foreigners, and so on down the ladder to kith and kin), there is reason to believe—for Petrinovich, at least—that anthropophagy is an evolved behavior.

The piece isn’t for the feint-hearted, but is certainly a fascinating take on one of the strongest of human taboos.

There is also a link at the bottom to a video discussion between “Robert Wright of BloggingHeads.tv and psychologist Paul Bloom of Yale on what motivates cannibals.”

From the appearance of the screen shot, I think they’ve been practising the look if nothing else.

Ecstasy may bring the love by filtering the fear

Ecstasy users often describe the high as feeling ‘loved up’ and MDMA is frequently described as an ’empathogen’ but until now, little was known about how it genuinely affects the recognition of emotions in other people.

A new study just published in Biological Psychiatry has tested the supposed ’empathy boosting’ effects of MDMA and found that it actually makes people worse at picking up on emotions in the face – but only for threatening expressions.

The researchers, led by psychologist Gillinder Bedi, met the volunteers on three occasions, and on each one they were given either MDMA (‘ecstasy’), placebo, or methamphetamine – the latter to be able to distinguish the effect of feeling ‘wired’ from any ecstasy-specific ’empathic’ effects.

Although everyone had agreed to which drugs would be given, the study was done using ‘double-blind’ conditions, meaning neither the researchers nor the participants knew which they were getting on any particular occasion.

An hour after swallowing the pill, the volunteers were asked to rate their mood and emotional state with standardised questionnaires and to take part in experiments to assess their ability to pick up on others’ emotions.

Two tests involved picking up emotion from the face, one from just the eyes, one from whole facial expressions, and another required participants to do the same for voices.

The volunteers reported that they felt significantly more ‘loving’, ‘friendly’ and ‘playful’ on MDMA, although paradoxically on a higher dose of the drug, it also increased feelings of loneliness.

Methamphetamine also boosted some of these feelings, although to a lesser extent, suggesting that part of the ‘loved up’ feeling is probably down to similar amphetamine-like effects in both drugs (MDMA is often described as a ‘substituted amphetamine’ because of its similar molecular structure).

Strikingly, the emotion tests showed no improvement in the ability to pick up on emotion after taking MDMA, and in fact, people were worse – but only at picking up on fearful, threatening emotions in facial expressions.

This suggests that ecstasy might be causing some of the famous feeling of ‘social connectedness’ by tuning out negative signals from other people faces, rather than boosting our ability to pick up on positive emotions.

Although only a first study, it indicates that the ’empathogen’ label is probably misleading because the drug actually makes us worse at reading others’ emotions.

But because we tend to associate ’empathy’ with positive social interactions, the effects of the drug have been linked to being empathic in popular culture.
