Lie Detection using Brain Waves: It’s just as creepy as it sounds…

by Gabriel in Lunatic Laboratories

Currently lie detectors (polygraphs) are not admissible in court, this is because (despite what you may read) there is little proof to show that they are much better than a guess — coming in at roughly 50% accuracy. They aren’t really based in science, making them more of a toy. There might just be a new contender in the lie detection department coming soon however, researchers have found that brain activity can be used to tell whether someone recognizes details they encountered in normal, d........

Maternal iron intake and offspring autism risk

by Paul Whiteley in Questioning Answers

Much like the discussions around the paper by Rogers and colleagues (see here) on treating autism in the first year of life, the media scrum around the findings from Rebecca Schmidt and colleagues [1] talking about maternal iron supplements and offspring autism spectrum disorder (ASD) risk preceded the publication of the paper by a few days. It's getting to be a pet-hate of mine that big headlines are being generated sometimes days before your average Jane or Joe can see the data upon which they........ Read more »

Gut issues in autism impacting on drug availability and absorption

by Paul Whiteley in Questioning Answers

As indicated in a recent post, I was really rather pleased to see the paper by Andrew Heitzer and colleagues [1] (open-access) asking the important question: Should clinical trial research of psychotropic medication in autism control for gastrointestinal symptoms? Some media about the study can also be found here."You write "Born to Kill" on your helmet and you wear a peace button".The answer is of course, yes and not just when it comes to psychotropic medicines either, given that gastroint........

If You’re Bicultural, You Can Make it Work to Your Advantage

by Louise Rasmussen in Head Smart

There are many advantages to being bicultural. Studies have shown that biculturals are more creative and enjoy greater professional success. One of the reasons for the advantage may be that exposure to diverse beliefs and worldviews enables biculturals to consider different perspectives. This can help them come up with new ways to solve problems and […]... Read more »

Omega-3 fatty acids and ADHD

by Paul Whiteley in Questioning Answers

With a title like that, this post could turn out to be quite a long winded blog entry. As it happens, I'm not going to subject you, dear reader, to such a literary onslaught but rather focus my attention on the paper by Elizabeth Hawkey & Joel Nigg [1] who undertook two meta-analyses and concluded that: "Omega-3 levels are reduced in children with ADHD [attention-deficit hyperactivity disorder]" and "Dietary supplementation appears to create modest improvements in symptoms"."Maybe the 80s wi........

The Short Story of Self-Control for Lawyers

by Dan DeFoe in Psycholawlogy

Juries hear the phrase “Excuse me, objection your Honor  . . . .”, or some other form, often not as polite, frequently during trials.  Due to TV and the movies, American jurors probably expect to hear the courtroom gladiator scream “I object . . . . !”   Alternatively, some lawyers ponder the dynamic flow [...]

New test for Diagnosing Alzheimer’s Early

by Gabriel in Lunatic Laboratories

Alzheimer’s diagnosis is important, like the famous slogan “with a stroke, time lost is brain lost,” detecting alzheimer’s is important in order to stave off cognitive decline. A just like a stroke time lost is brain lost. Unfortunately early diagnosis has been hard to come by, but now researchers say a simple test that combines thinking and movement can help to detect heightened risk for developing Alzheimer’s disease in a person. The best part, they say this will work even before the........ Read more »

Increasing parental age and autism severity?

by Paul Whiteley in Questioning Answers

An interesting paper by David Geier and colleagues [1] (open-access here) caught my eye recently, concluding that there was a lack of support for the suggestion that: "increasing parental age was associated with increasing autism spectrum disorder phenotypic severity"."the snozzberries taste like snozzberries".Before progressing through the paper and its possible implications, the eagle-eyed out there might have already spotted the name Dr Brian Hooker on the authorship list of the Geier paper. ........

Coffee Drinkers Have Trouble Talking About Emotions?

by Neuroskeptic in Neuroskeptic_Discover

People who drink a lot of coffee – and other caffeinated beverages – find it more difficult to identify and describe their own emotions. This is the claim of a new study, published in the Journal of Psychoactive Drugs, from Australian researchers Michael Lyvers and colleagues: Caffeine use and alexithymia in university students. “Alexithymia” – […]The post Coffee Drinkers Have Trouble Talking About Emotions? appeared first on Neuroskeptic....

Is Stress Eating Away at You? No, Literally…

by Gabriel in Lunatic Laboratories

Ever wonder why, when people are too stressed, they are often grouchy, grumpy, nasty, distracted or forgetful? It may not be something you’ve done, in fact it turns out stress is literally tearing apart the brain. By this I mean that researchers have just highlighted a fundamental synaptic mechanism that explains the relationship between chronic stress and the loss of social skills and cognitive impairment. When triggered by stress, an enzyme attacks a synaptic regulatory molecule in the brain........ Read more »

There's a problem with assuming the most intelligent candidates make the best employees

by BPS Research Digest in BPS Research Digest

Workplace research through the 20th Century suggested that selecting for intelligence is the best way to identify good performers. General mental ability (GMA), a popular recruitment measure that maps closely to the colloquial meaning of "intelligence", is strongly correlated with on-the job performance, well ahead of any other single measure.This consistent finding came from studies that mostly defined job performance as carrying out the duties expected in that role. Although intuitive, this ne........ Read more »

Why is poverty associated with mental health problems for some people, but not others?

by BPS Research Digest in BPS Research Digest

By guest blogger Peter Kinderman“I’ve been rich and I’ve been poor. Believe me, rich is better” (Mae West).  Critiques of the rather discredited "disease-model" of mental illness are commonplace, but we also need to articulate the alternative. New research by Sophie Wickham and colleagues helps do that, by providing support for the idea that we learn, as a consequence of our experiences in life, a framework of appraising, understanding and responding to new challenges. This psy........ Read more »

Anxiety and sensory over-responsivity linked to gut issues in autism

by Paul Whiteley in Questioning Answers

"The name's Lonnegan! Doyle Lonnegan!"Consider this micropost an extension of some previous discussions on this blog about how gastrointestinal (GI) issues present in cases of autism might show some connection to the presence of anxiety and sensory issues (see here). Today I'm discussing further research by Micah Mazurek and colleagues [1] which follows a previous publication by this author [2] on this topic.In the latest paper, Dr Mazurek and colleagues describe the course of abdominal pain in ........

Why are ethical standards higher in science than in business and media?

Facebook manipulates user content in the name of science? Scandalous! It manipulates user content in the name of profit? No worries! Want to run a Milgram study these days?

Does Your Cat Sniff New Food?

by CAPB in Companion Animal Psychology Blog

New research investigates which feline behaviours show that cats find food tasty. Photo: FreeBirdPhotos / ShutterstockThere are certain things we can take for granted when feeding the cat: the pitiful miaows that become increasingly strident, the anticipatory purring when you move towards the cat food, and the way the cat wraps herself around your leg as if you’re her best friend ever. But when you put the food down, is there any guarantee she will eat it? Cat food manufacturers have team........ Read more »

The Disgust Scale: How have we missed this all this time?

by Rita Handrich in The Jury Room

We’ve covered a lot of the disgust research so it is curious to us that somehow we missed sharing the actual Disgust Scale with you earlier. The Disgust Scale was developed by the infamous Jonathan Haidt (his surname is pronounced “height”) back in 1994 before disgust was considered cool. In brief, the Disgust Scale was […]

Autoimmune disease risk and eating disorders

"We were set up. The cops were waiting for us.""We observed an association between eating disorders and several autoimmune diseases with different genetic backgrounds. Our findings support the link between immune-mediated mechanisms and development of eating disorders".So said the paper by Anu Raevuori and colleagues [1] (open-access) based on an analysis of over 2300 people "treated at the Eating Disorder Unit of Helsinki University Central Hospital between 1995 and 2010" compared with nea........

Forgive yourself for relaxing in front of the TV and the couch time might actually do you some good

by BPS Research Digest in BPS Research Digest

There's a snobbishness about relaxation time. Tell someone your hobby is watching TV and chances are they'll look at you with derision. Mention meditation, reading or yoga and you're far more likely to attract nods of approval.And yet there is substantial evidence that time watching TV or playing video games can have a powerful restorative effect - just what many of us need after a hard day. This benefit isn't found for everyone, and in new paper Leonard Reinecke and his collaborators propose th........ Read more »

The schizophrenias (plural)

by Paul Whiteley in Questioning Answers

A micropost if you will, to draw your attention to the paper by Javier Arnedo and colleagues [1] mentioning the concept of 'the schizophrenias' (plural). Some media coverage of this paper can be found here and here. The crux of the paper is that although currently unified by a diagnostic label, schizophrenia seems to be comprised of various conditions: "caused by a moderate number of separate genotypic networks associated with several distinct clinical syndromes"."... dogs and cats living t........

Religion And Morality: Belief Isn't Better

by Alexis Delanoir in How to Paint Your Panda

It's no secret that when it comes to what the public thinks, atheists are usually at the bottom of the "nice" list. A survey in 2006 found that atheists were the least trusted minority group in America. Similar studies find that atheists are mistrusted and are seen as more immoral than their religious counterparts. But are these views justified? A new study by Hofmann et al. (2014) suggests they aren't, and this conclusion is consistent with other available data.... Read more »
