Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

A potential case of data manipulation has been uncovered in a psychology paper. The suspect article, Why money meanings matter in decisions to donate time and money, came out in 2012 from University of Arizona psychologists Promothesh Chatterjee, Randall L. Rose, and Jayati Sinha.
This study fell into the genre of 'social priming', specifically 'money priming'. The authors reported that making people think about cash reduces their willingness to help others, while thinking of credit cards has... Read more »
"The primary finding from the study was evidence of an improvement in several objective sleep parameters in participants in whom the increased colonization of lactic acid producing organisms was resolved after antibiotic treatment."Those were the words written by Melinda Jackson and colleagues  (open-access) who, during an open-label trial, looked at whether administration of an antibiotic (erythromycin 400 mg) over the course of 6 days might have some important effects on elements of sleep i........

This was the question faced by the participants in a rather extraordinary series of studies described in a new paper from Illinois psychologists Randy J. McCarthy and colleagues. In total, 1081 parents with children aged under 18 were presented with an outline of a person, and asked to imagine that it was their own child. They were told to think of a time when their child made them angry. Finally, they were asked how many pins they would like to stick into the "doll" in or... Read more »

A lot of has been written about how focusing too much on materialistic ambitions, at the expense of relationships and experiences, can leave us miserable and unfulfilled. In a new paper published in Social Psychological and Personality Science, a team of psychologists at the University of British Columbia in Canada argue that there's another important distinction to be made – between how much we prioritise time versus money. Those who favour time tend to be happier, possibly because this frees........ Read more »

"Vitamin D deficiency might contribute to the aetiology of ASD [autism spectrum disorder]. Supplementation of vitamin D3, which is a safe and cost-effective form of treatment, may significantly improve the outcome of some children with ASD, especially younger children."More big words have appeared from a research group who seem to be particularly interested in how vitamin D (the sunshine vitamin/hormone) might have some important links to at least some cases of autism. The findings thi........ Read more »

Genes could help in determining whether a person likes to rise early in the morning or not.
Researchers, in affiliation with 23andMe, Inc. recently worked on the DNA of 89,283 individuals, and found that genes could show some specific variations more frequently in the people, who self-identify themselves as early risers or morning people. They found 15 different spots in the genetic makeup that can vary between morning........ Read more »

The findings reported by Ciro Marangoni and colleagues  made for some interesting reading recently and their systematic review of longitudinal studies looking at the various environmental exposures put forward as possible risk factors pertinent to the development of bipolar disorder (BD).Trawling through the peer-reviewed material on this topic, the authors were able to 'clump' the various proposed risk factors into one of three categories: "neurodevelopment (maternal influenza during pr........

Depression is a serious issue for expecting mothers. Left untreated, depression could have implications for a fetus’s health. But treating the disease during pregnancy may carry health risks for the developing fetus, which makes an expecting mother’s decision whether to take medication a very difficult one. To better understand how antidepressants affect fetuses during pregnancy, scientists studied exposure in mice.

In our part of the world, a growing proportion of fathers are rolling up their sleeves and getting involved in early child care. This has prompted increased interest from psychologists in any similarities or differences in the way that mothers and fathers interact with their children. One finding is that fathers tend to engage in more physical play, whereas mothers spend more time playing with toys and interacting socially. A new study in the Quarterly Journal of Experimental Psychology takes a ........ Read more »

A survey of homeless youth finds that pets bring benefits – and difficulties.23% of homeless youth have pets, according to research by Harmony Rhoades et al (University of Southern California). The team surveyed 398 homeless youth at two drop-in centres in Los Angeles. While previous studies have shown that pets can be very important to homeless young people, this is the first quantitative study to look at pet ownership, mental health, and the use of services amongst this group.88% of the youn........

"The average prevalence of ASD [autism spectrum disorder] was 35/10 000 children and was about 4-fold higher in males."I don't have too much to add to the findings reported by Karolina Skonieczna-Żydecka and colleagues  who estimated the prevalence of ASD in two regions of Poland: "West Pomeranian and Pomeranian regions."

Inflammation is a good thing, it helps the body fight disease, and without it we wouldn't survive. Unfortunately, when inflammation isn't kept under control it can wreak havoc on the body. From potentially causing alzheimer's to arthritis it seems that unchecked inflammation can cause all sorts of issues. In fact, a new study adds to the list of issues out of control inflammation causes in the body.

It's something we're taught from a young age – when you're about to go into a rage, force yourself to count to ten and hopefully the storm will pass. This may sound like common sense, but without testing the method scientifically, how do we know if and when it really works? For example, while the counting delay could give you a chance to get a grip of your aggressive urges, it's equally plausible that it could give you time to grow even angrier about whatever triggered your displeasure in the ........

An estimated 1 in 68 children in the United States has autism. The neurodevelopmental disorder, which impairs communication and social interaction skills, can be treated with medications and behavioral therapies, though there is no cure. Now, University of Missouri researchers have found that a medication commonly used to treat high blood pressure and irregular heartbeats may have the potential to improve some social functions of individuals with autism.

One thing anxiety does is to upset your brain's balance between focus and vigilance. Your control over what you pay attention to is sacrificed at the expense of worrisome thoughts and a rapid response to any potential danger.If this account is true, basic attention training should help, putting you back in charge of your own mind. A key component of attentional control is working memory – our ability to juggle task-relevant information in mind over short-periods of time. In a new paper in Biol........ Read more »
