Working at a treadmill desk boosts your memory and concentration, researchers claim

by BPS Research Digest in BPS Research Digest

Image from Labonté-LeMoyne et al.We're told sitting is the new smoking and that we should consider working at standing desks, or perhaps better still, treadmill desks. Indeed, the health benefits of treadmill desks are indisputable, say neuroscientists in Canada, led by Élise Labonté-LeMoyne. More contentious, these researchers explain, is the evidence for the psychological effect of such set-ups on our work performance.For instance, one study found impaired maths problem solving while w........

More extremes of a limiting diet and autism

by Paul Whiteley in Questioning Answers

In a previous post a while back, I discussed some examples in the peer-reviewed literature of where a self-limiting diet in the extreme can lead to with autism in mind. Today, I'm adding a further example of what food faddism might mean, to further forward the point that "a low threshold for vitamin level testing should be undertaken in autistic spectrum disorder cases, highlighting the importance of enquiring about dietary habits."That last quote comes from the paper in question by Emma Du........

The neurological basis for anorexia nervosa

by Dr. Jekyll in Lunatic Laboratories

Most of us know about dieting, and if not first hand, have seen in the news or from friends how hard sticking to a diet long-term can be. This is because adults (regardless of their weight_ resolve to lose weight. Yet, more often than not, that chocolate lava cake is too enticing and that resolve vanishes. This behavior is normal because hunger increases the intensity of food rewards. Yet, individuals with anorexia nervosa (AN), despite their state of starvation, are able to ignore such food-rel........ Read more »

“We need smart jurors so we should keep the lighter skinned Black guy”

by Rita Handrich in The Jury Room

Most of us have heard of the preference for lighter skin within the African-American community. Some of us have also heard of “colorism” in general—a bias shared by many in our culture. Recently, author Lance Hannon (a sociologist from Villanova University) used data from the 2012 American National Election Study and found that Whites in […]

Team effectiveness is disproportionately influenced by your group's best performer or "extra-miler"

by BPS Research Digest in BPS Research Digest

The quality of a team's best performer (the "extra miler") is diagnostic of the group's overall effectiveness.In The Hobbit, fifteen companions come together on a quest for a dragon’s treasure. Traditional team analysis would judge "Thorin and Company" on the sum of its parts: Ori is stalwart, and Dori strongly stalwart, and, ok, Bifur seems stalwart enough … a fairly stalwart team, then. But we’re beginning to understand that single individuals can have a disproportionate impact on g........ Read more »

Early life probiotics reducing the risk of subsequent neuropsychiatric disorder?

by Paul Whiteley in Questioning Answers

With my continued interest in all-things gut microbiome on this blog (see here for example) it is little wonder that I was taken to blog about the study findings from Anna Pärtty and colleagues [1] reporting that: "Probiotic supplementation early in life may reduce the risk of neuropsychiatric disorder development later in childhood." Probiotic by the way, refers to various 'live' organisms (bacteria, yeasts) thought to confer some positive effect on health and/or wellbeing.Not only does such a........ Read more »

Toxoplasma gondii and schizophrenia (again and again)

The findings reported by Ainsah Omar and colleagues [1] (open-access available here) adding further weight to the notion of a "strong association between the active Tg [Toxoplasma gondii] infection and schizophrenia" are set out for your reading consumption today.Continuing a research topic that has already enjoyed quite a bit of air time on this blog (see here and see here) whereby the parasite T. gondii known to cause the condition toxoplasmosis might also be implicate........

Can Monkeys Get Depressed?

by Neuroskeptic in Neuroskeptic_Discover

According to a new study from Chinese neuroscientists Fan Xu and colleagues, some monkeys can experience depression in a similar way to humans.


The researchers studied cynomolgus monkeys, also known as crab-eating macaques (Macaca fascicularis), a species native to Southeast Asia. Cynomolgus monkeys are highly social animals. Xu et al. previously showed that isolating a monkey from its companions caused it to develop depression-like behaviors. In their new paper, the authors say that they'v... Read more »

“Classical music will protect you from Alzheimer’s” and  other lies on the internet

by Doug Keene in The Jury Room

This week I read several sensationalized reports of research findings from some scientists in Finland. “Classical music can help slow down the onset of dementia” and “Listening To Classical Music Could Improve Genes Responsible For Certain Brain Functions”. The articles reported that listening to a 20 minute Mozart violin concerto could stave off dementia and […]

Secular community groups are just as effective as religious ones in stimulating concern for others

by Tom Rees in Epiphenom

Researchers around the world have found that subliminal reminders of religion can have some fairly profound effects (for example, encouraging honesty, obedience, revenge and staying power – and, as we saw in the previous post – even risk taking). But is this specifically about religion? Perhaps being reminded about god makes people virtuous – but [Read More...]... Read more »

The impact of military deployment on children

by Dr. Jekyll in Lunatic Laboratories

Being a military family is hard, it’s hard for the person serving (obviously) and if divorce rates are any indication, it is also hard on the spouse. While the added stress of deployment on a family cannot adequately be explained, even as someone who has seen it first hand, those stresses affect even the littlest members of the family. A new study reports that following military parents’ return from combat deployment, their children show increased visits for mental healthcare, physical injur........ Read more »

Psychologists use magic to study the illusory feeling of free choice

by BPS Research Digest in BPS Research Digest

Most of the time, when a magician asks you to "pick a card" she makes it feel as though you have a free choice, but you don't really. The authors of a new paper say this is a microcosm for many real-life situations in which we feel free to choose, but in fact our choices are heavily influenced and constrained. Jay Olson, a magician and psychologist, and his colleagues, have put a classic card trick technique under the spotlight as a way to study the psychology behind this experience of illusory ........

Objective measures of sleep in autism meta-analysed

Not “just in your head,” brain networks differ among those with severe schizophrenia

by Dr. Jekyll in Lunatic Laboratories

The brain is plastic, it’s how we grow, it’s how we adapt, it is quite literally how we survive. This can unfortunately be to our detriment and new research shows that people with a severe form of schizophrenia have major differences in their brain networks compared to others with schizophrenia, bipolar disorder and healthy individuals. So while it may be true, that it is all be in your head, it isn’t how people usually mean it.... Read more »

The Right to Walk Away

by CAPB in Companion Animal Psychology Blog

What can pet owners learn from the way scientists give animals choices in research?When people take part in research, scientists must ensure they give informed consent. When the participants are pets, owners give consent on their behalf: they understand the risks of the research and they have the right to end their participation at any time (e.g. if they feel their dog is stressed). We can’t ask animals about their feelings, but scientists have several ways they give the pets a choice.In Sarah........ Read more »

"Look at me!": When we feel powerful, we find ourselves inspirational

by BPS Research Digest in BPS Research Digest

Matthew McConaughey may have surprised some during the 2014 Oscars ceremony when he listed his heroes: each one was a past, present or future version of himself. But it turns out that being your own inspiration isn’t unusual, especially for people who feel socially powerful and influential.A new study, led by Gerben van Kleef from the University of Amsterdam, asked 140 undergraduates to spend a few minutes writing about a personally inspiring event that took place in the prior five years.

The label of autism rarely exists in a diagnostic vacuum

by Paul Whiteley in Questioning Answers

"Most young ASD [autism spectrum disorder] children met the criteria for additional psychopathology." That was the primary conclusion reported by Fernando Salazar and colleagues [1].At the risk of sounding like a broken record going on and on about how the diagnosis/label of autism very rarely exists in a diagnostic vacuum when it comes to comorbidity, I did think it important that the findings of Salazar et al were [briefly] brought to your attention.
