One in six children develops PTSD after trauma, but differences exist

by Eva Alisic in Trauma Recovery

How many children develop Posttraumatic Stress Disorder after a traumatic experience such as an assault, a car crash, war or disaster? William Yule – one of the godfathers of child traumatic stress research – once pointed out that rates reported in separate studies varied from 0 to 100%. So what is the average rate to be expected? And are there differences between types of trauma? ... Read more »

The Mechanics of Mindful Improvements

by Katharine Blackwell in Contemplating Cognition

Every now and then, just when I start to get comfortable thinking I understand how something works, some new evidence or theory is presented that makes me call into question the things that I thought I knew. After years of following the latest developments in contemplative science, I thought I had a handle on how meditation helped develop self-control. And now, a new theory has been proposed that is rocking my world. Meditation may not work the way that I thought it did.... Read more »

Using A Foreign Language Influences Your Sense of Morality

by Eva de Lozanne in United Academics

Moral judgement is often considered to be a fixed given, based on deep-seated ideas on what is morally right and morally wrong. But, however counter-intuitive it may seem: recent research shows that people react differently to moral dilemmas when presented in a foreign language than in their native language.... Read more »

The wise do recover from addiction

by DJMac in Recovery Review

Wisdom’s not a very scientific term is it? We sort of know what it means, but it’s vague and not really something to value or measure in scientific literature – right? It’s a bit like spirituality; you might get a dozen different definitions depending on whom you talk to. That hasn’t stopped researchers exploring what [...]

Useful delusions, interface theory of perception, and religion

by Artem Kaznatcheev in Evolutionary Games Group

As you can guess from the name, evolutionary game theory (EGT) traces its roots to economics and evolutionary biology. Both of the progenitor fields assume it impossible, or unreasonably difficult, to observe the internal representations, beliefs, and preferences of the agents they model, and thus adopt a largely behaviorist view. My colleagues and I, however, […]... Read more »

Weighing up genetics and environment in autism

by Paul Whiteley in Questioning Answers

"Environment as important as genes in autism, study finds" read the press release about the study by Sven Sandin and colleagues [1]. Even the authors seemed to be taken aback by the weighting their results gave to a role for non-genetic factors contributing to autism risk as per their comments: "We were surprised by our findings as we did not expect the importance of environmental factors in autism to be so strong... It's now clear we need much more research to focus on identifying what the........ Read more »

Autistic behaviours and Down's syndrome

I believe it is obligatory to say 'May the 4th be with you' today given that it is Star Wars Day. If you prefer the Chewbacca version of this greeting, well take yer pick from his many and varied vocalisations... Even better, ponder how Ming the Merciless might approach the greeting (no, really he's [the actor] gonna be in episode VII).Pizza the Hutt @ cyclonebill @ Wikipedia Anyhow... today I want to talk about the paper by Georgina Warner and colleagues [1] and their q........

Predicting Suicide: A Statistical Scandal

by Neuroskeptic in Neuroskeptic_Discover

A shocking piece of statistics has been uncovered in a paper published in a respectable psychiatry journal. The offending article, Electrodermal hyporeactivity as a trait marker for suicidal propensity in uni- and bipolar depression, appeared in 2013 in the Journal of Psychiatry Research. It examined whether an ‘electrodermal hyporeactivity’ test – based on measuring the […]The post Predicting Suicide: A Statistical Scandal appeared first on Neuroskeptic.... Read more »

"We describe a 32-month-old patient with enteroviral encephalitis confirmed by polymerase chain reaction in cerebrospinal fluid, with unfavorable clinical course with marked developmental regression, autistic features, persistent stereotypes and aphasia".

Casomorphins and autism reignited?

by Paul Whiteley in Questioning Answers

For those who know me and some of my particular autism research interests, they'll understand that I was always going to be intrigued by the results reported by Oleg Sokolov and colleagues [1] on elevated levels of bovine casomorphin-7 immunoreactivity being reported in a small group of children with autism. Indeed, as per my last post plugging my new book (apologies for the very blatant plug!), casomorphins, the peptide breakdown products from the protein casein complete with opioid activi........

'What else can you expect from a Crappo?'

by BPS Research Digest in BPS Research Digest

Which slur is worse: “Cracker” or the “N-Word?” After a July 2013 debate on CNN in which a panel discussed this exact question, researchers from NYU – Abu Dhabi, The Sage Colleges, and Tilburg University set out to determine why people might perceive slurs directed at some groups as more offensive than those directed at others – and if group status has anything to do with it.P.J. Henry, Sarah Butler, and Mark Brandt first gathered over 200 college students and asked them to generate ........ Read more »

Study: Men smell and that will stress you out

by neuroecology in Neuroecology

A study in Nature Methods has kicked up a bit of a fuss: In 2007, his lab observed that mice spend less time licking a painful injection—a sign that they’re hurting—when a person is nearby, even if that “person” is a cardboard cutout of Paris Hilton.

Recursive Fury: Misunderstanding The Ethics of Criticism

by Neuroskeptic in Neuroskeptic_Discover

One month ago, a paper was retracted from Frontiers in Psychology. It was called “Recursive fury: conspiracist ideation in the blogosphere in response to research on conspiracist ideation”, from Australian psychologists Stephan Lewandowsky and colleagues. Most retractions are valuable corrections to the literature, taking flawed science or plagiarised work out of circulation.

On building a park to help a city population’s mental health

by Katharine Blackwell in Contemplating Cognition

Psychologists have been considering the possibility that a simple view of nature could provide substantial benefits at least as long as I’ve been alive – that’s when Science published a study showing that surgery patients with a view of a park healed faster than patients with a view of another building. In the decades since the focus has shifted to the potentially subtler yet more pervasive way that green scenes might help us, including the potential that a walk through a park ........ Read more »

Mind the gap: Overestimating income inequality

by BPS Research Digest in BPS Research Digest

How much money do you think you would have to make each year to land yourself in the infamous One Per Cent of salary earners?According to a new study, your answer is very likely to be wrong. Research conducted by John Chambers of St. Louis University and colleagues at the University of Florida reveals that – at least where Americans are concerned – people are actually significantly likely to overestimate how much money is earned by the richest people.This finding directly contradicts recent ........
