Behaviour Problems in Guide Dogs

by CAPB in Companion Animal Psychology Blog

The behavioural reasons why guide dogs sometimes end their working lives early, and what it means for pet dogs.A study by Geoffrey Caron-Lormier (University of Nottingham) et al looks at twenty years of data from Guide Dogs (UK). During this time, 7,770 working guide dogs, who had worked with blind or partially sighted people, were withdrawn from service. By far the most common reason was retirement, which applied to 6,465 dogs (83%). The authors looked at the reasons why other dogs were withdra........ Read more »

There's a simple trick to reduce your mind wandering while studying

by BPS Research Digest in BPS Research Digest

It happens to all of us – we're meant to be focused on the page in the book, but our mind is turned inwards thinking about other stuff (Must remember to charge my phone, What time did I say I'd meet Sarah?) Thankfully a new study in Memory and Cognition identifies a straightforward way to reduce how much your mind wanders off topic when you're studying. You just need to ensure the materials you're learning are in your sweet spot – not too easy and not too difficult.For one experiment, Judy X........ Read more »

Autism 'disclosure cards' and negative judgements?

by Paul Whiteley in Questioning Answers

I have to say that I initially felt slightly uncomfortable reading the study results published by Jillian Austin and colleagues [1] providing "preliminary validation for the use of autism disclosure cards in buffering negative judgment." Uncomfortable because, despite the fact that it is human nature for people to stop, stare and perhaps question something when it seems 'out of the ordinary', the idea that when children with autism specifically 'misbehave' in a public place their parents need to........

Emphasising that science involves collaboration and helping others increases its appeal as a career

by BPS Research Digest in BPS Research Digest

Scientific work is unfairly perceived by many people as a solitary, even lonely enterprise, concerned with abstracted goals rather than helping others. While some scientific work calls for a quiet room (at the least, noise-cancelling headphones), the reality is that the enterprise as a whole involves plenty of communal aspects, from collaboration and discussions to teaching and mentoring. In new research published in the Journal of Applied Psychology, researchers from the University of Miami hav........ Read more »

Listening to songs like "Angel of Death" protects heavy metal fans from existential angst

by BPS Research Digest in BPS Research Digest

Heavy metal band Black Label Society on stage Brazil, via Flickr/FockaListening to songs about death and dressing yourself in t-shirts featuring skulls and demons might seem like a strange way to combat existential angst. Nonetheless, a new study in Psychology of Popular Media Culture shows that listening to heavy metal helps fans of the genre deal with their own mortality. This is likely because to fans, heavy metal represents so much more than a genre, it embodies a way of life and a sense of ........ Read more »

1 in 3 people with CFS might benefit from methylphenidate?

by Paul Whiteley in Questioning Answers

I'm cautious about the findings reported by Daniel Blockmans & Philippe Persoons [1] talking about how long-term use of the stimulant medication methylphenidate (MPH) might be something to consider for at least some people diagnosed with chronic fatigue syndrome (CFS). Cautious because the sole use of a questionnaire looking "for possible improvement of concentration difficulties and fatigue" following the use of MPH on this research occasion is not exactly a top tier scientific method...Non........

Interleaving Study Is Not Interleaving Learning

by Joshua Fisher in Text Savvy

In the latest research, the authors found that a blocked schedule (presenting examples from one category at a time) outperformed an interleaved schedule (interspersing examples from all the categories) for category learning when the examples to be classified were more highly discriminable. This result was consistent across the two experiments in the study (p = 0.055 and p = 0.04). Importantly, however, although interleaving was a better strategy for learning categories of lower discriminability,........ Read more »

Secrets of the human brain unlocked

by Dr. Jekyll in Lunatic Laboratories

Human intelligence is being defined and measured for the first time ever. Researchers have been recently undertaken to quantify the brain's dynamic functions, and identify how different parts of the brain interact with each other at different times - namely, to discover how intellect works.

Reconsidering the Autism-Spectrum Quotient (AQ) for autism screening?

by Paul Whiteley in Questioning Answers

A quote to begin: "The AQ's [Autism Spectrum Quotient] utility for screening referrals was limited in this sample. Recommendations supporting the AQ's role in the assessment of adult ASD [autism spectrum disorder], e.g. UK NICE guidelines, may need to be reconsidered."Taken from the paper published by Ashwood and colleagues [1], the findings from this team don't make for great reading if you happen to be a fan of the AQ as a potential screening instrument for adult autism. Indeed,........ Read more »

Know your brain: Periaqueductal gray

by neurosci in Neuroscientifically Challenged

Where is the periaqueductal gray?















The periaqueductal gray, or PAG, is an area of gray matter found in the midbrain. The PAG surrounds the cerebral aqueduct (hence the name periaqueductal) and occupies a column of brainstem that stretches about 14 mm long. There are no obvious visible anatomical divisions within the PAG, but researchers have divided the PAG into four columns based on differences in connectivity and function: the dorsomedial, dorsolater........

Increased microbial translocation in ME/CFS

by Paul Whiteley in Questioning Answers

"The cause of ME/CFS [myalgic encephalomyelitis/chronic fatigue syndrome] is unknown, but gut dysbiosis could be contributing to some of the symptoms and their severity. Developing therapeutic interventions aimed at reducing local inflammation, restoring gastrointestinal tract immunity and integrity and modifying the intestinal microbiome may ameliorate ME/CFS symptoms in a number of affected patients."Those were the important conclusions reported by Ludovic Giloteaux and colleagues [1........

How to test for music skills

by Richard Kunert in Brain's Idea

In a new article I evaluate a recently developed test for music listening skills. To my great surprise the test behaves very well. This could open the path to better understand the psychology underlying music listening. Why am I surprised? I got my first taste of how difficult it is to replicate published scientific results […]... Read more »

Does target shooting make teenagers aggressive?

by BPS Research Digest in BPS Research Digest

When the dust settles on the tragedy of the latest mass shooting, gun clubs usually see a spike in their memberships as people look to arm and defend themselves. At the same time, many others argue for greater gun controls, and from their perspective, recreational target shooting is very much part of the problem, not the answer.Anecdotally, this is borne out by the many killers who often turn out to have been target shooters. Indeed, in Germany after the teenage perpetrators of two spree atrocit........ Read more »

Another study to watch... vitamin D and/or fatty acid supplements for autism

by Paul Whiteley in Questioning Answers

Hot on the heels of a recent post about a study to watch for (see here) details of yet another "randomised, double-blind, placebo-controlled trial" have been published in the form of the trial protocol by Hajar Mazahery and colleagues [1].This time around the aim is to "investigate the effect of vitamin D, n-3 LCPUFAs [omega-3 long chain polyunsaturated fatty acids] or a combination of both on core symptoms of ASD [autism spectrum disorder]" and hopefully with it, the generat........

Facial expressions of intense joy and pain are indistinguishable

by BPS Research Digest in BPS Research Digest

Eyes shut tight, face contorted into a grimace. Are they ecstatic or anguished? Ignorant of the context, it can be hard to tell. Recent research that involved participants looking at images of the facial expressions of professional tennis players supported this intuition – participants naive to the context were unable to tell the difference between the winners and losers.From a scientific perspective, the problem with the tennis study is that the findings might have been affected by the player........

Gastrin-releasing peptide and autism?

by Paul Whiteley in Questioning Answers

"Gastrin-releasing peptide was safe and well tolerated by most subjects and may be effective for core symptoms of autism."So said the results of the study - open trial - by Michele Michelin Becker and colleagues [1] continuing a research theme from this author [2] on the potential need for further scientific scrutiny when it comes to the use of gastrin-releasing peptides (GRP) and autism. Emphasising again that results were based on the use of an open trial (everyone knew what was bein........ Read more »

"Shocking" new role of the immune system: Controlling social interaction

by Dr. Jekyll in Lunatic Laboratories

In a startling discovery that raises fundamental questions about human behavior, researchers have determined that the immune system directly affects - and even controls - creatures' social behavior, such as their desire to interact with others. So could immune system problems contribute to an inability to have normal social interactions?

Educating Children Reduces Risky Behaviour Around Dogs

by CAPB in Companion Animal Psychology Blog

Dog safety education for children works, according to a systematic review of existing research.The CDC estimates that 4.5 million Americans are bitten by a dog every year. Children are at high risk, and bites to children are often more severe than those to adults. Bites to the head and neck are more common than for adults because children are smaller.The CDC says “Among children, the rate of dog-bite–related injuries is highest for those 5 to 9 years old. Children are more likely than adults........ Read more »

Psychologists still don't know why you are oblivious to your blinks

by BPS Research Digest in BPS Research Digest

If you were sat in a dark room and the lights flickered off every few seconds, you'd definitely notice. Yet when your blinks make the world go momentarily dark – and bear in mind most of us perform around 12 to 15 of these every minute – you are mostly oblivious. It certainly doesn't feel like someone is flicking the lights on and off. How can this be?A new study in Journal of Experimental Psychology: Human Perception and Performance has tested two possibilities – one is that after each bl........ Read more »

Immune reactivity to gluten and (some) autism continued

by Paul Whiteley in Questioning Answers

Not so long ago I blogged about the research paper from Faezeh Ghalichi and colleagues [1] (see here) describing the result of their relatively small scale (non-blinded, not placebo-controlled) trial on the use of a gluten-free diet (GFD) with a cohort of children diagnosed with an autism spectrum disorder (ASD).The results, taking into account certain methodological issues, were generally quite favourable when it came to the analysed behavioural measurements used and importantly on the presence........
