Researchers in Hungary have discovered a clear link between repeat polymorphism in the tyrosine hydroxylase (TH) gene with activity-impulsivity in German Shepherd dogs. The research is presented in the journal PLoS ONE. http://phys.org/news248953636.html Biology Mon, 20 Feb 2012 09:47:23 EST news248953636 A new research project into the role of sport in rehabilitating young prisoners has found that sport can be effective in reducing the reconviction rate of offenders. http://phys.org/news246114131.html Other Sciences Wed, 18 Jan 2012 13:02:17 EST news246114131 Though "variety is the spice of life" and "opposites attract," most people marry only those whose political views align with their own, according to new research from Rice University and the University of Nebraska-Lincoln. Political scientists found that political attitudes were among the strongest shared traits and even stronger than qualities like personality or looks. http://phys.org/news224259705.html Other Sciences Tue, 10 May 2011 15:22:13 EST news224259705 Drug abuse is probably linked to an in-built tendency to act without thinking, as shown by studies of siblings of chronic stimulant users, a leading neuroscientist will claim this week. http://phys.org/news219581950.html Medicine & Health Thu, 17 Mar 2011 11:59:36 EST news219581950 It seems that women become addicted to cocaine more easily than men and find it harder to give up. New research published in BioMed Central's open access journal Biology of Sex Differences reinforces this position by showing that the motivation of female rats to work for cocaine is much higher than males. http://phys.org/news219038325.html Biology Fri, 11 Mar 2011 03:59:05 EST news219038325 Impulsive behaviour can be improved with training and the improvement is marked by specific brain changes, according to a new Queen's University study. http://phys.org/news204301537.html Medicine & Health Tue, 21 Sep 2010 15:26:20 EST news204301537 Adults with attention-deficit/hyperactivity disorder (ADHD) who received medication and individual sessions of cognitive behavioral therapy (CBT) showed greater improvement in symptoms through 12 months compared to patients who did not receive CBT, according to a study in the August 25 issue of JAMA. http://phys.org/news201886201.html Medicine & Health Tue, 24 Aug 2010 17:00:01 EST news201886201 Previous studies have found that the personality trait impulsivity, or a lack of planning and forethought regarding behaviors, is associated with alcohol use and alcohol-use disorders. For most individuals, impulsivity decreases during emerging and young adulthood. Some, however, do not "mature out" of impulsivity. Now, University of Missouri researchers have found that individuals who exhibited the largest declines in impulsivity from ages 18-25 also exhibited the sharpest decreases in alcohol consumption during this time frame. Understanding why some individuals "mature out" of impulsivity and others do not could lead to improved treatment for alcohol-use disorders. http://phys.org/news197029984.html Medicine & Health Tue, 29 Jun 2010 12:00:01 EST news197029984 Teens who were in high-quality child care settings as young children scored slightly higher on measures of academic and cognitive achievement and were slightly less likely to report acting-out behaviors than peers who were in lower-quality child care arrangements during their early years, according to the latest analysis of a long-running study funded by the National Institutes of Health. http://phys.org/news193035872.html Medicine & Health Fri, 14 May 2010 06:05:04 EST news193035872 ADHD, or attention-deficit/hyperactivity disorder, is among the costliest of behavioral disorders. Its combination of inattention, impulsivity and hyperactivity leads to accidental injuries, school failure, substance abuse, antisocial behavior and more. Yet despite nearly a century of study, the disorder's roots remain mysterious. http://phys.org/news183906394.html Medicine & Health Thu, 28 Jan 2010 13:20:06 EST news183906394 Toddlers are distractible. Their minds flit constantly here and there, and they have a terrible time concentrating on even the most stimulating project. They might be fascinated by a colorful new toy, but only until the next best toy comes along. This can be maddening for parents or teachers, who often try to rein in a toddler's impulsivity. http://phys.org/news178903032.html Medicine & Health Tue, 01 Dec 2009 15:17:44 EST news178903032 A recent Finnish study suggests that children's short sleep duration even without sleeping difficulties increases the risk for behavioral symptoms of ADHD. http://phys.org/news160056251.html Medicine & Health Mon, 27 Apr 2009 13:04:46 EST news160056251
