Everybody’s an expert these days. Pest Control Expert, Plumbing Expert, Weather Expert, and so on. What does it really mean to have expertise? Take a minute to think about what expertise means to you. If ideas like superior intelligence, heightened perceptual skills, and photographic memory come to mind, you may be thinking of superheroes, or [...]... Read more »

Canine cognition is a hot topic these days, using experiments and brain imaging as research tools. The trouble with brain imaging work is that it is invasive, to the extent that animals may have to be sedated or anaesthetized for the study. All that changed with the amazing work of Gregory Berns et al and the first-ever fMRI study on awake, unrestrained dogs last year. Now Miiamaaria Kujala et al in Finland have shown that it is also possible to do a non-invasive EEG with dogs.An EEG measur........ Read more »

Tick – tock. The “billable hour” determines so much in the lives of many professionals, including lawyers. Many have to “keep time”.

In a recent research conducted by two scientists from Brock University in Canada, the authors have proposed and tested several mediation models. With such models they have proven that lower cognitive ability predicts greater prejudice, an effect mediated through the endorsement of right-wing ideologies (social conservatism, right-wing authoritarianism) and low levels of contact with out-groups....

It’s time to stop scoffing at the synesthetes: linking music to colors is totally normal. It’s not really about the notes, though. Researchers say the colors we find in music are actually the colors of the emotions the music makes us feel.
Synesthetes are people whose sensory experiences overlap; they most often link letters or numbers to certain colors. Music-color synesthesia, in which hearing music triggers the colors, is rarer. In fact, when Stephen Palmer and Karen Schloss at the........ Read more »
Negotiation training has been shown to lead to positive outcomes for parties on both sides of the table, identifying 'win-win' solutions and helping the wheels of the world turn more amicably. But many studies focus on consequences when both negotiators are trained using the same methodology, when the reality is that a counterpart from another organisation may be trained differently or not at all. What happens then? A study by Alfred Zerres and colleagues finds out.The study recruited 360 busine........ Read more »

What is going on in the brain of someone who has the deluded belief that they are brain dead? A team of researchers led by neuropsychologist Vanessa Charland-Varville at CHU Sart-Tilman Hospital and the University of Liege has attempted to find out by scanning the brain of a depressed patient who held this very belief.
The researchers used a Positron Emission Tomography (PET) scanner, which is the first time this scanning technology has been used on a patient with this kind of delusion -........ Read more »

By Dr. Ken Broda-Bahm: Think of the situations where self-diagnosis wouldn't work very well: A police officer asking, "Do you think you were speeding?" or a doctor inquiring, "Do you believe your cancer is in remission?" Yet we still rely on self-diagnosis when trying to discover and eliminate bias in civil and criminal cases by essentially asking prospective jurors, "Are you biased?" A new study (Robertson, Yokum & Palmer, 2013) takes a look at whether we can rely on jurors to identify their ow........ Read more »

A while ago we did a focus group on a shockingly unethical healthcare provider targeting lower income zip codes for insurance fraud and the phrase “those Mexicans” came up in the deliberations. “That’s a good business model”, an older Caucasian woman said, “because those Mexicans will do whatever you tell them to do”.

Publication of US psychiatry's updated diagnostic code has provoked renewed debate in recent weeks over the extent to which mental illness ought to be framed as a psychosocial or a biological problem. The answer of course is that it is both. A new Canadian study captures this interplay, showing how close friendships mitigate the risk for girls whose genes mean they are more vulnerable than average to depression.

Human infants require a lot of care, and our evolution owes a lot of how well, and how long we take, to raise our offspring. So, it’s very important that not only parents pay close attention to their young children, it’s also evolutionary important that extended family members (grandparents, siblings, even friends) can give their attention to another person’s child...
