Don't touch! On the mixed effects of avoidant instructions

by BPS Research Digest in BPS Research Digest

What happens if you tell a golfer not to over-shoot a putt? Does it make them more likely to overshoot (an ironic effect, like the way suppressing thoughts of white bears actually leads to bear-based thoughts) or does it provoke over-compensation - putts that are particularly short? The same question could be asked for similar situations in other sports and also for movement instructions in the psychology lab.

Past research has produced mixed results - sometimes ironic effects are observed, ot........ Read more »

The revenge of history

by Jeremy in Agricultural Biodiversity Weblog

Three papers today which look into the role of history in determining patterns of diversity, at the species and genetic level. I don’t have much time today, so descriptions will have to be quick and dirty for now. In Molecular Ecology, Hoban et al. used microsatellites to genotype 29 populations of Juglans cinerea from throughout [...]... Read more »

The History of Smoking Bans & Anti-Smoking Sentiment

by John Wayland in The Darwin Tribune

In the opinion of this Editor, it seems that the smoking bans in force in various nations upon the globe, as well as anti-smoking lobbyists, are a modern occurance which have only popped up in the last few decades as research began to show the harmful effects of smoking, namely lung cancer.It was a suprise therefore to discover that there has been a long history of smoking bans, and anti-smoking sentiment. This article will attempt to explore some of the history of the smoking ban and anti-smoki........ Read more »

The Worrying Case of the Turtle Tumors

by Journal Watch Online in Journal Watch Online

Researchers may have solved the mystery behind a disease that leaves Hawaiin sea turtles with hideous tumors – and the tracks lead back to land, and to an amino acid called arginine.
The Green sea turtle (Chelonia mydas) is an endangered species found around the world, mostly in tropical seas. Off Hawaii, populations have been […] Read More »... Read more »

New analysis of population trends and their impact on global greenhouse gas emissions

by Phil Camill in Global Change: Intersection of Nature and Culture

In 40 years, there will be about 3 billion additional people living on the Earth (~9.5 billion total) compared with today.   With all of these new folks, it’s easy to think about the added demands of energy, food, and water required to sustain their lifestyles.  And in terms of climate warming, it’s hard to escape [...]...

The organic halo alters food and exercise choices

by Colby Vorland in Biofortified

From Nutritional Blogma Nutrient-based claims on food labels are shown in some research to promote calorie underestimation.  This is often called the health halo effect; certain buzz words associated with what people consider healthy cause them to overgeneralize other attributes of a food, downplay the number of calories, and not pay as much attention to the nutrition facts panel. A couple recent studies by Schuldt and Schwarz (1) show this happens with the Continue reading...... Read more »

Mr Smart and Heroman

by Tom Rees in Epiphenom

Let me introduce you to Mr Smart and Heroman. Mr Smart is really, really clever. So clever that he knows everything - like what's inside a closed box. Heroman is not so smart, but he does have a special power. Heroman has x-ray vision, so that he can see into the closed box.

Here's a picture of Mr Smart. He looks a bit like a lot of Professors I know.

Both Mr Smart and Heroman had a key role to play in a recent study by Jonathan Lane, of the University of Michigan, and colleagues, into how ch........ Read more »

Flexibility – of the psychological kind

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

More holiday reading to ponder… One of the fascinating developments in psychology over the past 50 years is the ongoing study into what constitutes psychological health. It’s been known by many names – ego-resilience, executive control and self-regulation – but the work on these areas hasn’t been pulled together into a coherent whole until recently. … Read more...

Kid's sequential drawings

by Neil Cohn in The Visual Linguist

This is a summary/review of an article I thought had particularly compelling evidence for why understanding sequential images is a learned trait. Highlights are all mine...Narratives of urban Japanese children (manga) were compared to those of village Egyptian children. The argument was made that development differs based on graphically “rich” versus graphically “poor” environments. Egyptian ... Read more »

Altered sea turtle sex ratios: Can global warming harm warm-water animals?

by WhySharksMatter in Southern Fried Science

When most people think of an animal threatened by global warming, images of a polar bear drowning because of lost ice habitat come to mind. Few know that climate change can also threaten animals used to living in environments much warmer than the Arctic. Even when you’re used to heat, too much heat can be a [...]... Read more »

The deaf have super vision, and other tales of neural plasticity

by Casey Rentz in Natural Selections

Ever been asked--if you had to choose, would you rather be deaf or blind? Its a futile hypothetical dilemma (as if the choice is ever available to anyone to make) that was probably first posed by some perpetually dramatic and irrevocably bored teenager OR--could it be--by a neuroscientist!

Perhaps we cherry pick vision and hearing for our speculative crises because they are particularly important to us and essential to achieve something our species is known for: high level mobility and naviga........ Read more »

Family Therapy for Adolescent Anorexia Nervosa

by William Yates, M.D. in Brain Posts

There is very limited research to guideline clinicians, patients and their family members in choosing the best treatments for anorexia nervosa and other eating disorders.  So when a well-designed and informative study is published it is noteworthy and important to review.   James Lock and colleagues summarized their findings from a randomized trial of family therapy versus individual therapy in a randomized controlled trial for adolescents with anorexia nervosa in the October 2010........

Feeling the pressure – the inherent inaccuracy of BP measurement
