Often, we will carefully deliberate the pros and cons of each item, taking into consideration past experiences with similar situations before making our ultimate choice. However, a new study suggests that cognitive stress, such as distraction, can influence this balanced, logical approach to decision making. http://www.physorg.com/news177269248.html Medicine & Health Thu, 12 Nov 2009 17:50:01 EST news177269248 (PhysOrg.com) -- A robot powered by a computerized model of a rodent brain will help researchers from UC Irvine and UC San Diego understand how people recognize and adapt to change. http://www.physorg.com/news176581936.html Electronics Wed, 04 Nov 2009 18:34:30 EST news176581936 As flu season approaches, parents around the country are starting to face school closures. But how bad should an influenza outbreak be for a school to shut down? A study led by epidemiologists John Brownstein, PhD, and Anne Gatewood Hoen, PhD of the Children's Hospital Boston Informatics Program, in collaboration Asami Sasaki of the University of Niigata Prefecture (Niigata, Japan), tapped a detailed set of Japanese data to help guide decision making by schools and government agencies. The analysis was published by the Centers for Disease Control and Prevention in the November issue of Emerging Infectious Diseases. http://www.physorg.com/news176570555.html Medicine & Health Wed, 04 Nov 2009 15:40:01 EST news176570555 A University of Pittsburgh study sheds new light on the relationship between race, body weight and sexual behavior among adolescent girls. The results suggest that a girl's ethnicity and her actual weight or perception of her weight may play a role in her participation in risky sexual behaviors. The study results are published in the November issue of Pediatrics, now available online. http://www.physorg.com/news176033215.html Medicine & Health Thu, 29 Oct 2009 11:07:22 EST news176033215 (PhysOrg.com) -- Everyday, people are required to make decisions quickly and flexibly. In a flash, they must weigh up the advantages, disadvantages and possible consequences of their behaviour and coordinate it with the relevant external circumstances. This learning process involves the messenger substance dopamine. http://www.physorg.com/news175796621.html Medicine & Health Mon, 26 Oct 2009 18:00:01 EST news175796621 Computer scientists from Nanyang Technological University in Singapore are working on the development of an efficient and intelligent facial expression recognition system.

Researchers have long noted that the overall popularity of a name exerts a strong influence on people's preferences -- more popular names, such as Robert or Susan, are more frequent and, by their sheer ubiquity, drive more parents to adopt a similar choice. However, new research by psychologists at New York University and Indiana University, Bloomington suggests that the change in popularity of a name over time increasingly influences naming decisions in the United States. Like momentum traders in the stock market, parents today appear to favor names that have recently risen in popularity relative to names that are on the decline. http://www.physorg.com/news174633865.html Medicine & Health Tue, 13 Oct 2009 06:27:37 EST news174633865 (PhysOrg.com) -- When business leaders leave organizations following poor decisions, constituents often find comfort in replacing them with insiders - others familiar with the problem and original choices. http://www.physorg.com/news173549567.html Other Sciences Wed, 30 Sep 2009 17:30:03 EST news173549567 (PhysOrg.com) -- Picture this.

The answer may partly depend on your genetic make-up, according to new research from UCL (University College London) and funded by the Wellcome Trust. http://www.physorg.com/news160765568.html Medicine & Health Tue, 05 May 2009 18:06:30 EST news160765568 When you're on a diet, deciding to skip your favorite calorie-laden foods and eat something healthier takes a whole lot of self-control--an ability that seems to come easier to some of us than others. Now, scientists from the California Institute of Technology have uncovered differences in the brains of people who are able to exercise self-control versus those who find it almost impossible. http://www.physorg.com/news160320079.html Medicine & Health Thu, 30 Apr 2009 14:23:04 EST news160320079 Addictive behaviour is determined by conscious, rapid thought processes, not necessarily by the content of visual stimuli as previously thought according to research funded by the Biotechnology and Biological Sciences Research Council (BBSRC). http://www.physorg.com/news160214377.html Medicine & Health Wed, 29 Apr 2009 09:00:40 EST news160214377 People with higher measures of cognitive ability are more likely to make good choices in several different types of economic decisions, according to a new study with researchers from the University of Minnesota's Twin Cities and Morris campuses. http://www.physorg.com/news160077614.html Other Sciences Mon, 27 Apr 2009 19:01:04 EST news160077614 (PhysOrg.com) -- Humans don`t always make the most rational decisions. As studies have shown, even when logic and reasoning point in one direction, sometimes we chose the opposite route, motivated by personal bias or simply "wishful thinking." This paradoxical human behavior has resisted explanation by classical decision theory for over a decade. But now, scientists have shown that a quantum probability model can provide a simple explanation for human decision-making - and may eventually help explain the success of human cognition overall. http://www.physorg.com/news158928941.html Medicine & Health Tue, 14 Apr 2009 11:56:09 EST news158928941
