In answer to the question posed in the title of this post on whether coeliac disease (CD) might show some connection to intellectual (learning) disability, 'probably not' is the finding reported by Taner Sezer and colleagues .Researchers initially looked at "serum levels of tissue transglutaminase antibody and total IgA" in over 230 children diagnosed with nonsyndromic intellectual disability compared with about the same number of asymptomatic controls. Nonsyndromic intellectual dis........ Read more »

Horror video games target evolved defence mechanismsby confronting the player with fright-inducing stimulisuch as darkness and hostile entities. By guest blogger Mathias ClasenThe video game industry outpaced the movie industry several years ago, and video games remain a rapidly growing market. In 2014, US consumers spent more than $22 billion on game content, hardware, and accessories. While researchers in media psychology have been busy investigating and discussing the effects of violent ........ Read more »

I must thank Leah Hardy (@LeahFHardy) for bringing to my attention the paper by Qinglong Shang and colleagues  (open-access available here) reporting that: "Ad36 [Human adenovirus 36] infection is associated with an increased risk of obesity development."Based on a meta-analysis of the available research literature examining whether Ad-36 - "a nonenveloped icosahedral virus comprised of double-stranded DNA and is one of 56 serotypes in 7 subgroups of human adenoviruses" - might........

Rapid eye movement or REM sleep actively converts waking experiences into lasting memories and abilities in young brains reports a new study. The finding broadens the understanding of children’s sleep needs and calls into question the increasing use of REM-disrupting medications such as stimulants and antidepressants.

When you smile at a party, your facial expression is emotionally consistent with the happy context and as a consequence other guests will in future be more likely to remember that they've seen your face before, and where you were when they saw you. That's according to a team of Italian researchers led by Stefania Righi who have explored how memory for a face is affected by the emotion shown on that face and the congruence between that emotional expression and its surrounding context.The research........

Can we learn without being aware of what we're learning? Many psychologists say that 'unconscious', or implicit, learning exists.
But in a new paper, London-based psychologists Vadillo, Konstantinidis, and Shanks call the evidence for this into question.
Vadillo et al. focus on one particular example of implicit learning, the contextual cueing paradigm. This involves a series of stimulus patterns, each consisting of a number of "L" shapes and one "T" shape in various orientations. For ... Read more »

I was really rather happy to see the "preliminary evidence" reported by Rebecca Schmidt and colleagues  when it came to examining whether selected vitamin D metabolic gene variants might show linkage to autism spectrum disorder (ASD) based on data derived from the CHARGE initiative.For quite a while now I've discussed the various peer-reviewed science on the topic of vitamin D deficiency / insufficiency with autism in mind on this blog (see here and see here for example).

For many shy people, online social networking sites have an obvious appeal – a way to socialise without the unpredictable immediacy of a face-to-face encounter. However, a new study finds that people who are socially anxious betray their awkwardness on Facebook, much as they do in the offline world. The researchers Aaron Weidman and Cheri Levinson said their findings could hint at ways for socially anxious people to conceal their nervousness and attract more online friends.Seventy-seven studen........

For decades, researchers in the genetics field have theorized that the protein spools around which DNA is wound, histones, remain constant in the brain, never changing after development in the womb. Now, researchers from the Icahn School of Medicine at Mount Sinai have discovered that histones are steadily replaced in brain cells throughout life – a process which helps to switch genes on and off....

Parental age at offspring conception/birth in relation to offspring autism risk has been a recurrent theme in autism research circles for quite a few years now. I've covered it more than once on this blog (see here for example) and the various suggestions that advancing parental age in particular, might elevate the risk of offspring autism.Set in this context, the paper by Sven Sandin and colleagues  (open-access) (a name not unfamiliar to this blog) adds to the research evidence based on the........

When psychologists scan the brains of a group of people, they usually do so in the hope that the findings will generalise more widely. For example, if they find that there are correlations between localised brain shrinkage and mental performance in a group of healthy older participants, they will usually infer that such correlations apply in healthy older people more generally. But there's an important problem with this logic (one that applies to other fields of psychology): what if the people w........ Read more »

Children no longer obey their parents; every man wants to write a book and the end of the world is evidently approaching. So said a clay tablet inscribed almost 5 thousand years ago. But the world still stands, although we do go through golden and dark ages and societies rise and fall. Technology's golden age is now. or so we hope. How are current generations influenced by it and how will they shape the future world? Even as they age, Baby Boomers embrace emerging technologies such as smartphone........ Read more »

Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear.
