Exploding the 10,000 hours myth - it's no guarantee for greatness

by BPS Research Digest in BPS Research Digest

Swedish psychologist K. Anders Ericsson has studied elite performers in music, chess and sport for decades, and he says the main distinguishing characteristic of experts is the amount of deliberate practice they've invested - typically over 10,000 hours.This is painstaking practice performed for the sole purpose of improving one's skill level. Best-selling authors like Gladwell, Daniel Pink, Matthew Syed and others, have taken Ericsson's results and distilled them into the uplifting message that........ Read more »

AAP policy statement on iodine deficiency and pollutants

by Paul Whiteley in Questioning Answers

The quite recent policy statement from the American Academy of Pediatrics (AAP) drafted by Rogan and colleagues [1] is the source for today's short(ish) post. Highlighting a growing concern on the issue of iodine deficiency in women of reproductive age, the policy document also raises awareness of "commonly encountered environmental chemicals" potentially exacerbating such deficiency, and in particular "thiocyanate, nitrate and perchlorate". These chemicals are specifically mentioned because of ........ Read more »

A gluten-free diet for asymptomatic patients with coeliac disease

by Paul Whiteley in Questioning Answers

The tip of the iceberg? @ Wikipedia Today I'd like to focus on the paper by Kalle Kurppa and colleagues [1] and their suggestion that: "GFDs [gluten-free diets] benefit asymptomatic EMA-positive [endomysial antibody] patients" with coeliac (celiac) disease in mind.Asymptomatic, when it comes to a condition like coeliac disease (CD) - an autoimmune condition linked to the consumption of gluten - is not necessarily all that surprising given the numbers of cases w........

The claim is that neuroscientists have shown that, […]The post Another Education Neuromyth Debunked appeared first on Neuroskeptic.... Read more »

THE FUTURE OF FOOD?

by Lucy Gee in Antisense Science

In the world food has always been a necessity, but for most it represents a ritual, a pleasure, our culture. For many of us it’s synonymous with celebration and often associated with some of the happier moments in our lives – but do we need it? One man, Rob Rhinehart has embarked on a new life, without the need for solid food. He has created a product named Soylent (I know what you’re thinking, like that sci-fi book right? We’ve all heard of Soylent Green), which is an en........ Read more »

Objects Bring Fear the Closer They Appear

Quick: which of these things should you worry about if it’s coming toward you? a.) grizzly bear b.) pedestrian c.) frowny face emoticon You many not have time to assess all the risks (is the bear running? does the frowny face have greater-than-symbol eyebrows?).

What is “Cultural IQ” training and does it really work?

by BPS Research Digest in BPS Research Digest

IQ was once the only game in town. Now it rubs shoulders with a gaggle of human ability measures such as Emotional Intelligence, Empathy Quotient, and Rationality Quotient. The increasingly interconnected and diverse world of work has magnified interest in another newcomer: CQ, or cultural intelligence. With it come courses promising to prepare their students to work with colleagues, partners and customers who have different values and norms. A new paper investigates how effective this training ........ Read more »

Scurvy, vitamin C and autism

by Paul Whiteley in Questioning Answers

I'd been thinking about writing this post on scurvy, vitamin C and autism for quite a while. The paper by Kitcharoensakkul and colleagues [1] really made the decision for me, following their discussions on three young children with walking difficulties who were eventually diagnosed with scurvy, one of whom was diagnosed with autism. The authors concluded: "These clinical manifestations and radiologic findings highlight the importance for rheumatologists to have a higher index of suspicion f........ Read more »

Increased rates of suicidal ideation in adults with Asperger syndrome

"Our findings lend support to anecdotal reports of increased rates of suicidal ideation in adults with Asperger's syndrome, and depression as an important potential risk factor for suicidality in adults with this condition".Sunrise @ Wikipedia That was the very stark conclusion reached by the study by Sarah Cassidy and colleagues [1] (open-access) looking at self-reported rates of suicide ideation and suicide plans/attempts in a sample of adults newly diagnosed with Asperger syndr........

How can we increase altruism towards future generations?

by BPS Research Digest in BPS Research Digest

By guest blogger Dan JonesLike many parents, I often wonder what kind of world my two-year-old son will grow up to inhabit. Will the planet be ravaged by extreme climatic events, depleted of vital forests and biodiversity? Although some of our fears about the future may be overblown, if we don’t want to leave the planet in ruins for future generations, we need to think about how we act today — and maybe change our ways.Some changes are likely to involve minor sacrifices or small inconvenienc........

Men who are ashamed of their bodies are more prone to sexual aggression against women - US study

by BPS Research Digest in BPS Research Digest

When men are aggressive towards women, their behaviour is often driven by the feeling that their masculinity has been threatened. Consider these previous findings: men told they'd performed poorly on a strength test gave more painful electric shocks to a woman who criticised them; and men whose masculine identity was threatened subsequently harassed a feminist woman by sending her pornographic photos.Now Kris Mescher and Laurie Rudman have shown that this link is particularly strong for men who ........

Silence ENO2! More epigenetics and autism

by Paul Whiteley in Questioning Answers

The paper by Yu Wang and colleagues [1] (open-access here) concluded that: "reduced ENO2 expression may be a biomarker for a subset of autistic children" following their genome-wide methylation study of autism. For those who've picked up the word 'methylation' in that first sentence, this is yet another sign that epigenetics - the science of changes to gene function not entailing structural genomic changes - is starting to impact on autism research.Silentio! @ Wikipedia Based on an ini........

Is it possible to predict who will benefit from cognitive behavioural therapy (CBT)?

by BPS Research Digest in BPS Research Digest

The rise of CBT has been welcomed by many as safe, effective alternative to drug treatments for mental illness. However, there are also fears that CBT has grown too dominant, crowding out other less structured, more time consuming forms of psychotherapy.The fact is, CBT doesn't work for everyone. Precious resources could be better managed, and alternative approaches sensibly considered, if there were a way to predict in advance those patients who are likely to benefit from CBT, and those who are........
