In a massive research effort published in Biological Psychiatry, eleven international research groups collaborated to pool brain imaging data from adults with bipolar disorder. This allowed them to perform a mega-analysis to evaluate the differences in brain structure between individuals with bipolar disorder and healthy comparison subjects.
Consumers often have a distorted view when they compare information that involves numbers, according to a new study in the Journal of Consumer Research.
Although many human factors/ergonomics studies conducted over the past few years indicate that drivers who talk on the phone fail to attend to the road and increase the likelihood of an accident, the monotony of driving may also pose an accident risk. New research by HF/E researchers at the University of Kansas, Lawrence, published in Human Factors, suggests that drivers who lose focus on the road because of boredom may actually increase their attention by engaging in a secondary task, particularly during the last leg of their journey.
Two research studies published today in Neurology, the medical journal of the American Academy of Neurology, found markers for measuring the ability of children with Attention Deficit Hyperactivity Disorder (ADHD) to control impulsive movements, which may reveal insights into the neurobiology of ADHD, inform prognosis and guide treatments.
Women prefer female service providers in situations where they might fall prey to stereotypes about their math and science abilities, according to a new study in the Journal of Consumer Research.
People make purchasing decisions by choosing between alternatives or by rejecting certain options. But a new study in the Journal of Consumer Research finds that focusing on ruling out an option can lead consumers to reverse their preferences.
For many women in violent relationships, leaving is not an option. Yet a woman’s arsenal of defenses for resisting violence critically depends on her position within the family and community, according to new research from Concordia University published in the journal Review of Radical Political Economics.
You might think that a loving partner helps keep you on track—say, when you want to stick to your jogging or concentrate on your studies. But a new study in Psychological Science, a publication of the Association of Psychological Science, reports the opposite: Thinking about the support a significant other offers in pursuing goals can undermine the motivation to work toward those goals—and can increase procrastination before getting down to work.
The objective of this research is to understand how cooperation works in nature in general, and among humans in particular. From the evolutionary point of view it is very difficult to understand why we would help others when what interests us is helping ourselves, explained the authors of this study, which was recently published in the journal PLoS ONE.
The human brain consists of approximately one hundred billion nerve cells. Each of these cells needs to connect to specific other cells during the brain’s development in order to form a fully functional organism. Yet how does a nerve cell know where it should grow and which cells to contact? Scientists of the Max Planck Institute of Neurobiology in Martinsried have now shown that growing nerve cells realise when they’ve reached their target area in the fly brain thanks to the interaction of two genes.
Grownups have a good sense of what’s fair. Research now shows that this is true for young children, too. In a study published in Psychological Science, a journal of the Association for Psychological Science, three-year-old children shared with a peer after they worked together to earn a reward, even in situations where it would be easy for one child to keep all of the spoils for himself.
Most of us are familiar with the idea of image compression in computers. File extensions like .jpg or .png signify that millions of pixel values have been compressed into a more efficient format, reducing file size by a factor of 10 or more with little or no apparent change in image quality. The full set of original pixel values would occupy too much space in computer memory and take too long to transmit across networks.
