A study of more than 400 children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) has found a link between the children’s routine play settings and the severity of their symptoms, researchers report. Those who regularly play in outdoor settings with lots of green (grass and trees, for example) have milder ADHD symptoms than those who play indoors or in built outdoor environments, the researchers found. The association holds even when the researchers controlled for income and other variables. Included in this report is a link to download a free copy of the full text, original study.

University of Missouri researchers have found evidence that shows those who quit smoking show improvements in their overall personality. “The data indicate that for some young adults smoking is impulsive,” said Andrew Littlefield, a doctoral student in the Department of Psychology in the College of Arts and Science. “That means that 18-year-olds are acting without a lot of forethought and favor immediate rewards over long term negative consequences. They might say, ‘I know smoking is bad for me, but I’m going to do it anyway.’
Impulsive individuals tend to display aggressive behavior and have challenges ranging from drug and alcohol abuse, to problem gambling and difficult relationships. They are less able to adapt to different social situations. Impulsivity is also a common feature of psychiatric disorders. New research in Biological Psychiatry shows that people may react this way, in part, because they have lower levels of GABA (gamma-aminobutyric acid), the most important inhibitory neurotransmitter, in a specific part of their brain involved in regulating self-control.
Susan, even at age 33, cannot sit still. She never could. Pegged by her teachers as the resident “problem child,” she spent most of her afternoons in detention for disrupting class and forgetting her homework assignments. As an adult, she still struggles to meet her work deadlines, and she has to fight the insatiable urge to dart out of meetings.
How the brain controls impulsive behavior may be significantly different than psychologists have thought for the last 40 years. That is the unexpected conclusion of a study by an international team of neuroscientists published in the Aug. 31 issue of the Journal of Neuroscience.
Alcohol and impulsivity are a dangerous mix: People with current drinking problems and poor impulse control are more likely to die in the next 15 years, a new study suggests. However, they could get by with a little help from their friends: The study also found that a strong social support network buffers the toxic effects of impulsivity.
People with personality traits of high neuroticism and low conscientiousness are likely to go through cycles of gaining and losing weight throughout their lives, according to an examination of 50 years of data in a study published by the American Psychological Association. The publisher made the original study available for free for an undetermined length of time; check the end of this report for a download link.
Inhibitory control can be boosted with a mild form of brain stimulation, according to a study published in the June 2011 issue of Neuroimage, Elsevier’s Journal of Brain Function. The study’s findings indicate that non-invasive intervention can greatly improve patients’ inhibitory control. Conducted by a research team led by Dr. Chi-Hung Juan of the Institute of Cognitive Neuroscience, National Central University in Taiwan, the research was sponsored by the National Science Council in Taiwan, the UK Medical Research Council, the Royal Society Wolfson Merit Award, and a Fulbright Award.
