Magic Mushroom Users who get High without Drugs

by Scott McGreal in Eye on Psych

A study comparing peak experiences - what a person considers their most wonderful life experience - in psilocybin users with non-users, found that some users said their most intense peak experience had occurred when they were not under the influence of drugs, even though it involved a profound alteration of consciousness similar to that produced by psilocybin. One possible implication of this study is that psilocybin could have lasting effects on a person’s ability to enter altered states of c........ Read more »

What can physical activity do for ADHD?

by Paul Whiteley in Questioning Answers

In answer to the question posed in the title of this post, I might refer you to the paper by Susanne Ziereis & Petra Jansen [1] who concluded that results of their research study looking at the impact of two 12-week training programs "support the hypothesis that long-term PA [physical activity] has a positive effect on executive functions of children with ADHD [attention-deficit hyperactivity disorder]."That's the funny thing about birthdays, they're kind of an annual thi........

Know your brain: Reward system

by neurosci in Neuroscientifically Challenged

Where is the reward system?The term reward system refers to a group of structures that are activated by rewarding or reinforcing stimuli (e.g. addictive drugs). When exposed to a rewarding stimulus, the brain responds by increasing release of the neurotransmitter dopamine and thus the structures associated with the reward system are found along the major dopamine pathways in the brain. The mesolimbic dopamine pathway is thought to play a primary role in the reward system. It connects the ventral........ Read more »

Conspiracy beliefs and the relation to emotional uncertainty

by Rita Handrich in The Jury Room

It is no secret that we are intrigued by conspiracy theorists here at The Jury Room. Not only are they good for entertainment value during pretrial research, they are also very useful to help us plug holes in case narrative that could derail deliberations. When it comes to the actual trial though, conspiracy enthusiasts are […]

The gut and 15q Duplication Syndrome

by Paul Whiteley in Questioning Answers

"The results indicate that GI [gastrointestinal] symptoms are common in Dup15q syndrome and may have an atypical presentation."Let's just say I'm Frankenstein's monster. And I'm looking for my creator.That was the conclusion reached in the paper by Elias Shaaya and colleagues [1] following a review of medical records for a small-ish group of participants diagnosed with chromosome 15q duplication syndrome (dup15q syndrome), a genetic condition "involving copy number gains of the ma........

Reverse psychology: How bad managers inspire team camaraderie

by BPS Research Digest in BPS Research Digest

An unfair, uncaring manager makes for an uncertain working life, one characterised by stress, absenteeism and poor performance. But new research suggests a silver lining: when the boss is unjust, team members come together.A multi-institution collaboration led by Adam Stoverink presented teams of students with an awkward event. The students thought they’d been recruited to solve tasks for a cash prize, but they were left twiddling their thumbs while waiting for an assigned supervisor to show u........ Read more »

Psychological Theory and Gamification of Learning

by Richard Landers in NeoAcademic

Gamification, the use of game elements in non-game contexts, is increasingly being implemented in both student and organizational learning initiatives. Many of these efforts are atheoretical, meaning that the teachers using them don’t necessarily have a well-grounded reason for gamifying. Instead, they often gamify with the intention of making learning more “fun.” Unfortunately, 1) not […]The post Psychological Theory and Gamification of Learning appeared first on NeoAcad........

Moral mornings: Are we more willing to cheat and lie as the day goes on?

by Katharine Blackwell in Contemplating Cognition

A year or so ago, you might have encountered advice on the news sites to trust others more in the morning, because as the day wears on people become more inclined to lie, cheat, or steal. (Forbes was one place that peddled this particular tidbit ). This idea may not be back in the news now, but it is back in researchers’ minds thanks to a follow-up duet of articles debating what really might be behind any influence of time of day on our moral decisions. So this will be the first part of a ........ Read more »

How to get kids to tell the truth? It's not all about carrot or stick

by BPS Research Digest in BPS Research Digest

By guest blogger Dan JonesAll parents have to come to terms with the fact that their little angels will, from time to time, act like little devils. They’ll throw tantrums over trivial issues, or they’ll push, hit, bite or scratch other kids. And at some point they’ll start lying about what they’ve done.Lying is perfectly normal among children, not a sign of a sociopath in the making. Many kids start telling the odd fib around their second birthday, and by the time they’re 4 or 5 they........ Read more »

Maternal thyroid autoantibody and offspring autism risk

by Paul Whiteley in Questioning Answers

I have, on this blog, previously mentioned the paper by Alan Brown and colleagues [1] suggesting that: "The prevalence of maternal TPO-Ab+ [thyroid peroxidase antibody] was significantly increased in pregnancies giving rise to autism cases (6.15%) compared to controls (3.54%)." It was during some discussion on the suggested diagnosis of Down syndrome disintegrative disorder (see here) and the idea that some signs and symptoms of regressive autism (?) might overlap with TPO antibodies i........

The hidden neurological impact of explosions on military members

by Dr. Jekyll in Lunatic Laboratories

More bad news for war Veterans, the brains of some Iraq and Afghanistan combat veterans who survived blasts from improvised explosive devices (IEDs) and died later of other causes show a distinctive honeycomb pattern of broken and swollen nerve fibers throughout critical brain regions, including those that control executive function. The pattern is different from brain damage caused by car crashes, drug overdoses or collision sports, and may be the never-before-reported signature of blast injuri........ Read more »

Imagining walking through a doorway triggers increased forgetting

by BPS Research Digest in BPS Research Digest

We've all had that experience of going purposefully from one room to another, only to get there and forget why we made the journey. Four years ago, researcher Gabriel Radvansky and his colleagues stripped this effect down, showing that the simple act of passing through a doorway induces forgetting. Now psychologists at Knox College, USA, have taken things further, demonstrating that merely imagining walking through a doorway is enough to trigger increased forgetfulness.

Do Hand-Reared Wolves get Attached to their Humans?

by CAPB in Companion Animal Psychology Blog

Researchers test the bond between captive wolf pups and the humans who rear them.Photo: Geoffrey Kuchera / ShutterstockWe all think our dogs form attachments to us, but previous studies with wolf pups have suggested they don’t attach to their caregiver in the same way. While a 16-week old puppy is already attached to its owner, scientists found the same is not true of a 16-week old wolf. However, the way the wolf pup is raised and the age of testing may have an effect. New research by Nathanie........ Read more »

Simple Jury Persuasion: When minority jurors  are not so good for your client

by Doug Keene in The Jury Room

Here’s an odd counter-intuitive research finding. You might think that, if you have a gay or lesbian client, other minorities (like racial or ethnic minorities, for example) would be a good bet for your jury. It only makes sense that those who have experienced discrimination themselves would be more tolerant toward members of other oppressed […]

Autism research in Jamaica

by Paul Whiteley in Questioning Answers

For the past couple of years I've been tracking some rather interesting publications coming out of data from Jamaica on the topic of autism / autism spectrum disorder (ASD) specifically looking at the possible overlap between genes and various environmental factors. I thought now would be a good time to bring this collection of papers to the blogging table and summarise their findings based on the analysis of data collected from The Jamaican Autism study. The fact that their latest res........ Read more »

People may be happier when their neighbourhood fits their personality

by BPS Research Digest in BPS Research Digest

Levels of trait "openness to experience"are higher in central London than otherareas of the city. Image from PNAS. It is surely easier to be happy in some neighbourhoods than others. But a new study suggests one size does not fit all. Based on data from 56,000 Londoners collected by a BBC initiative, Markus Jokela and his colleagues report that the correlations between different personality dimensions and life satisfaction vary across the capital. The researchers say this shows "finding the........ Read more »

Autism diagnosis as a predictor of slow colonic transit

by Paul Whiteley in Questioning Answers

Slow colonic transit is all about issues with the speed of gastrointestinal (GI) motility and how as well as deriving nourishment from our food/drink, the other important task which our gut undertakes is the removal of waste, which it generally does pretty well. The paper by Zainab Ridha and colleagues [1] suggested that a diagnosis of autism might be over-represented when it came to their review of children referred for "nuclear transit studies", that is measuring bowel transit by mea........

How do viruses work in making us smart?

by Usman Paracha in SayPeople

Main Point:

Viruses are important in making us smarter by improving the basic functions of the brain, especially the regulation of gene expressions.

Published in:

Cell Reports

Study Further:

Researchers from Lund University in Sweden have found that millions of year’s old inherited viruses can have special impact on the development of complex networks in the brain of human beings.

Previously, it was clear that endogenous retroviruses make nearly 5% of DNA of human beings,........ Read more »

Cataloging a year of blogging: the philosophical turn

by Artem Kaznatcheev in Evolutionary Games Group

Passion and motivation are strange and confusing facets of being. Many things about them feel paradoxical. For example, I really enjoy writing, categorizing, and — obviously, if you’ve read many of the introductory paragraphs on TheEGG — blabbing on far too long about myself. So you’d expect that I would have been extremely motivated to […]... Read more »
