Autism diagnoses (and diagnostic stability) in Germany

by Paul Whiteley in Questioning Answers

"From 2006 to 2012, the prevalence of autism spectrum disorder diagnoses in 0- to 24-year-olds increased from 0.22% to 0.38%."That was one of the details included in the rather interesting paper by Christian Bachmann and colleagues [1] who provided some introductory information on the the trends in autism diagnoses in Germany. I say 'introductory information' because it appears that autism or autism spectrum disorder (ASD) has not exactly received the research attention in Germany that it p........ Read more »

Why Do Political Figures Lie So Blatantly?

by The Neurocritic in The Neurocritic

Are They Pathological Liars? Narcissists? Psychopaths? “Masterful Manipulators”? 





Trump Spokesman’s Lecture on Media Accuracy Is Peppered With Lies


Nearly all American politicians lie, but few as blatantly as those affiliated with the present administration. How do they do it? Are they lacking a conscience? Do they believe their own lies? Do they start with small falsehoods, stretch the

Nature Shapes Faithful and Unfaithful Brains

by Miss Behavior in The Scorpion and the Frog

Among monogamous animals, some individuals are more faithful than others. Could these differences in fidelity be, in part, because of differences in our brains? And if so, why does this diversity in brain and behavior exist?A snuggly prairie vole family. Photo from theNerdPatrol at Wikimedia Commons.Prairie voles are small North American rodents that form monogamous pair bonds, share parental duties, and defend their homes.

"no evidence that the probiotic formulation is effective in treating low mood"

by Paul Whiteley in Questioning Answers

I'm a great believer in balance when it comes to this blog and its content. As enthusiastic as I might be about a particular topic or topics, I don't want to lose sight of the fact that peer-reviewed science is a messy business and often filled with contrary findings.With 'contrary' in mind, I want to talk today about a paper by Amy Romijn and colleagues [1] detailing the results of a double-blind, randomised, placebo-controlled trial of a probiotic mix which contained "freeze-dried L. helv........

Diagnosing ME/CFS the machine learning way?

The correlates of regressive autism

Finding Out if Dogs Like Cats - Or Not

by CAPB in Companion Animal Psychology Blog

A new study investigates the best way to find out if a dog will get on with cats.When dogs are waiting for adoption at a shelter, a common question is “what is the dog like with cats?” But at the moment there’s no validated way to test dogs to see if they will be friendly to cats.Some dogs become good friends with cats, but other dogs want to chase and kill them, so it would really help if shelters knew if a dog is cat-friendly.Sometimes the person who surrenders a dog will provide informa........
