Greetings cards for mental illness

Greetings card manufacturer Hallmark have released a new line of cards especially for the person in your life experiencing mental illness, such as depression or an eating disorder, or other traumatic and difficult times.

ABC News has a report on the cards which are designed with colours to reflect the mood of the situation and pithy messages to match:

For eating disorders: “All I want is for you to be healthy and happy with yourself. Please take it one day at a time until you are.”

For depression: “When the world gets heavy, remember, I’m here to help carry it with you.”

There’s no word on cards for psychosis or paranoia (maybe “Like you, I never trusted those neighbours and their infernal thought stealing machines”) or people detained under the mental health act (“Kafkaesque doesn’t begin to describe the situation. Have a successful tribunal”).

Perhaps I’ve found a gap in the market?

Top ten psychology studies

Jeremy Dean of PsyBlog is currently doing a run down of his top ten psychology studies and will conclude the series by asking for a vote for the reader’s favourite.

He’s writing up each one as a separate article, so you get a flavour of what the study involved and how it changed our knowledge of psychology.

So far, five out of the ten have been covered and include influential studies such as the one that laid the foundations for cognitive behavioural therapy and another where euphoria was induced by experimental trickery.

The full list will be released and written-up over the coming weeks, and a vote will decide the winner!

SciAm Mind Matters

Scientific American have launched a new weekly blog seminar on the mind and brain where they target a particular study and get leading psychologists and neuroscientists give their take on it.

The editors give a quick run down of the study itself, while the invited commentators pull out the crucial issues or points of controversy.

So far they’ve looked at PTSD, navigation, environmental enrichment and the science of decision making, and there’s a new focus every week.

Five minutes with Howard Dully

howard_dully.jpgDave Isay, Piya Kochhar and Howard Dully produced one of the most powerful radio documentaries of 2005 where Howard told the story of his own lobotomy and the quest to make sense of the experience.

A lobotomy is a type of brain surgery to disconnect parts of the frontal lobes from the rest of the brain.

It was originally devised by Egas Moniz as a treatment for psychiatric illness because it seemed to have a ‘calming’ effect.

Howard was given the operation when only 12 years old by Walter Freeman – the world’s most enthusiastic evangelist for this procedure.

The procedure is now almost entirely disused, owing to the poor outcomes and dangers of the procedure, but it has left a legacy of people with permanently altered lives.

Howard wanted to understand how this dangerous procedure came to be so widely used and how it came to be performed on him as a child. He has also been kind enough to talk to Mind Hacks about his experiences.

The human is the only animal that…

Psychologist Daniel Gilbert on the unwritten vow taken by psychologists. From p3 of Stumbling on Happiness (ISBN 9780007183135).

Few people realise that psychologists also take a vow, promising that at some point in their professional lives they will publish a book, a chapter or at least an article that contains the sentence: ‘The human being is the only animal that…’ We are allowed to finish the sentence any way we like, but it has to start with those eight words.

Most of us wait to relatively late in our careers to fulfil this solemn obligation because we know that successive generations of psychologists will ignore all the other words that we managed to pack into a lifetime of well-intentioned scholarship and remember us mainly for how we finished The Sentence.

We also know that the worse we do, the better we will be remembered. For instance, those psychologists who finished The Sentence with ‘can use language’ were particularly well remembered when chimpanzees were taught to communicate with hand signs.

And when researchers discovered that chimps in the wild used sticks to extract tasty termites from their mounds (and to bash each other over the head now and again), the world suddenly remembered the full name and mailing address of every psychologist who ever finished The Sentence with the words ‘uses tools’.

So it is with good reason that most psychologists put off completing The Sentence for as long as they can, hoping that if they wait long enough, they might just die in time to avoid being publicly humiliated by a monkey.

Why psychologists study twins

The BPS Research Digest has a concise article on a key way of determining how much genetics influences the expression of a psychological trait – the twin study.

The article is part of a new series where professional researchers are asked to write short articles on key topics.

This one is by Dr Angelica Ronald from London’s Institute of Psychiatry who researches the autism spectrum.

Twin designs address the nature-nurture question. Behaviour geneticists compare how alike one twin is with the other twin on whatever variable they are interested in; in my case this is autistic behaviours. If genes influence variation in autistic behaviours, identical twin pairs who share all their genes will be highly similar in their degree of autistic behaviours whereas fraternal twins will be much less similar. This is what we have found.

Twin studies have been essential in understanding the effects of genetics but are controversial with some researchers as there are various ways of determining the outcome which may not always be in agreement.

This is your brain on Britney

Wendy, Stephanie and Marie, three high school psychology students, have voiced over Britney’s Baby One More Time video with lyrics about the occipital lobe.

It is, dare I say, a work of genius (and very funny to boot).

And if you’re interested in reading a study on the cognitive neuroscience of Britney’s brain, one was recently published by the Mackledoodle Institute of Radioscopy.

The findings are, er… unique.

The light and dark of attraction in SciAmMind

A new edition of Scientific American Mind has been published and, as is customary, two of their feature articles are online, each on a different end of the human attraction spectrum.

The first looks at online dating and how the psychology of relationships is altered by perusing your potential partners on a website.

One of the most significant differences stems from how the internet allows people to have quite a fine-grained control over how they present themselves online – even to the point where being ‘economical with the truth’ is a fairly standard tactic.

For men, the major areas of deception are educational level, income, height, age and marital status; at least 13 percent of online male suitors are thought to be married. For women, the major areas of deception are weight, physical appearance and age. All of the relevant research shows the importance of physical appearance for both sexes, and online daters interpret the absence of photos negatively. According to one recent survey, men’s profiles without photos draw one fourth the response of those with photos, and women’s profiles without photos draw only one sixth the response of those with photos.

The second article examines the psychology and treatment of paedophilia – sexual attraction to children.

Often paedophiles are described as ‘evil’ by the media, as if this was an explanation rather than a label that describes the gravity of their acts.

Knowing how best to protect children, through both the legal and medical system, need a deeper understanding. The SciAmMind article looks both at current theories and how they’re applied in practice.

The science of happiness

The Harvard Magazine has an in-depth article on the psychology of happiness and personal growth.

Whereas this was previously the domain of pop psychology and self-help books, the development of ‘positive psychology’ in the last decade has attracted serious researchers determined to understand how the mind and brain support positive attributes and emotions.

We covered this topic before when The New York Times published a very well researched article on the field.

Positive psychology was initially treated with scepticism but now seems to be largely in the mainstream of psychology research and is gathering significant public attention.

Chronic Brian damage

Another in the occasional series of PubMed typos. This time from the Scandanavian Journal of Social Medicine.

The last line accidentally describes the effect of exposure to solvents on one unfortunate individual:

A cohort study of disability pension and death among painters with special regard to disabling presenile dementia as an occupational disease.

Scand J Soc Med Suppl. 1980;16:34-43.

Mikkelsen S.

In the last decade several investigations have demonstrated an association between impaired cerebral function in employed workers and occupational exposure to organic solvents. Many case-histories and two case-referent studies indicate, that such an impairment might develop into disabling irreversible neuropsychiatric disease. The main purpose of this study was to further investigate the risk of chronic brain damage in solvent exposed workers. A cohort of 2601 male painters and 1790 male bricklayers from the Copenhagen area was identified retrospectively and followed Jan. 1,71-Dec. 31,75. For this period the incidence of disability pensioning and mortality was examined for the two occupational groups and for a “‘normal” population of Copenhagen men. Using bricklayers and Copenhagen men as referents, the painters had a relative risk of approximately 3.5 of being awarded a disability pension due to a state of being awarded a disability pension due to a state of cryptogenic presenile dementia. When indications of alcohol abuse, cerebral concussions or other etiologic factors were present, the relative risk was approximately 2. No excess risk was found for neuropsychiatric diseases other than presenile dementia. Other differences between the groups were found, but they were inconsistent and difficult to interpret. In the light of the findings of this and other studies, it seems likely, that chronic brian damage may result from industrial exposure to organic solvents.

Faces, faces everywhere

The New York Times has a brief article on why we have a tendency to see faces in chaotic or almost random visual scenes.

The tendency to see meaning in essentially random data is variously known as apophenia or pareidolia, and statistically would be known as a Type I error – a false positive.

Although it is controversial as to whether it is specifically dedicated to recognising faces, an area of the brain known as the fusiform gyrus is certainly heavily involved in perceiving faces.

The fact that this area is so specialised for faces might lead us to detect faces even when they are only suggested by a few dots, the position of clouds or the markings on just about anything.

“The information faces convey is so rich ‚Äî not just regarding another person’s identity, but also their mental state, health and other factors,” he said. “It’s extremely beneficial for the brain to become good at the task of face recognition and not to be very strict in its inclusion criteria. The cost of missing a face is higher than the cost of declaring a nonface to be a face.”

There’s a great web page with pictures of ‘cloud faces‘ if you want to see how spectacular some of these effects can be.

Early social experiences can influence adult behavior in romantic relationships. More on the same from the San Francisco Chronicle.

Love activates the same brain areas as cocaine, reports the The New York Sun. It also activates the same brain areas as chess, but apparently that isn’t worthy of a mention.

A transhumanist dictionary

George Dvorsky has published a guide to the terms and buzzwords of transhumanism – an optimistic movement that seeks to apply current and future scientific discoveries to extending human experience and abilities.

Transhumanists are interested in neuroscience as a way of improving on the natural human range, either through optimising the biological systems already present or extending them with technological interfaces.

They are variously treated with excitement, suspicion and amusement by mainstream scientists who tend to be conservative by nature.

However, the movement has attracted some leading lights in the sciences who are not put off by the sometimes science-fiction focus of the transhuman mission.

You may see lots of references to the Singularity, a key concept in transhumanist thought.

It’s exact meaning differs depending on the context, but one of the most influential definitions is from Ray Kurzweil who uses it to describe the notional point when computers will overtake the abilities of the human brain.

Needless to say, this puts the back up of many philosophers and cognitive scientists who believe that computers will never be able to fully emulate human intelligence or consciousness.

There’s plenty more of these thorny issues touched on by Dvorsky’s dictionary, so have a look through if you want to know what the dreamers of neuroscience are thinking about.

Mad love

Highlighting the striking parallels between our least understood and most exalted states of mind, Nietzsche commented that “there is always some madness in love”.

Perhaps the reason love has such a good reputation when compared to other forms of madness, is its effect on mood.

Euphoria, arousal, elation, talkativeness and flights of fancy can fill the mind in the most pleasurable way and it’s interesting that these are also core symptoms of mania – one end of the manic-depressive spectrum.

The defining feature of madness is delusion, however, where the affected person holds a fixed, unrealistic belief despite persuasive contrary evidence.

People in love are notorious for their unusual beliefs and, indeed, research has shown that we tend to hold unlikely and overly positive beliefs about our lovers.

Romance doesn’t even need a willing partner in some cases, as people who are diagnosed with de Clerambault’s syndrome hold the delusional belief that another person is in love with them, even if they’ve never met.

The original subject of de Clerambault’s seminal case study was a 53 year old woman who believed that King George V was in love with her and signalled his desires by moving the curtains of Buckingham Palace.

It seems madness and love are, in many ways, soul mates, and perhaps we should be grateful for their shared history.

Indeed, madness is at its most spectacular when shared, and the prospect of falling sanely in love with someone surely seems to miss the point.

The power of praise

There’s a fascinating article in The New York Magazine about the dramatic effects of different types of praise on a child’s success when tackling new challenges.

A team of researchers led by Prof Carole Dweck asked children to complete a series of short tests, and randomly divided into groups. Each child was given a single line of praise.

One group was praised for their intelligence (“You must be smart at this”), while the others were praised for their effort (“You must have worked really hard”). This simple difference had a startling effect.

Children who were praised for their effort were more likely to choose a harder test when given a choice, were less likely to become disheartened when given a test they were guaranteed to fail, and when finally given the original tests again, their marks improved.

In contrast, the children praised for their intelligence tended to choose an easier test if asked, were distressed by failure, and actually had worse marks after re-taking the original tests.

Dweck had suspected that praise could backfire, but even she was surprised by the magnitude of the effect. “Emphasizing effort gives a child a variable that they can control,” she explains. “They come to see themselves as in control of their success. Emphasizing natural intelligence takes it out of the child’s control, and it provides no good recipe for responding to a failure.”

In follow-up interviews, Dweck discovered that those who think that innate intelligence is the key to success begin to discount the importance of effort. I am smart, the kids’ reasoning goes; I don’t need to put out effort. Expending effort becomes stigmatized‚Äîit’s public proof that you can’t cut it on your natural gifts.

Repeating her experiments, Dweck found this effect of praise on performance held true for students of every socioeconomic class. It hit both boys and girls—the very brightest girls especially (they collapsed the most following failure).

The article is fascinating, although it seems the writer has somewhat overused the phrase ‘the inverse power of praise’ and might lead some people to think that praise itself has an ‘inverse effect’.

Praising children is incredibly important. Countless psychological studies have shown that excessive critical comments have a damaging effect on mental health.

This research just suggests that in terms of encouraging children to tackle challenges effectively, praising their effort seems more effective than praising their intelligence.

The article is a thorough look at the issues raised by this research, and how it is being applied in education.
