Imagine a boy sitting in front of a computer screen, controlling what appears on the monitor with only his brainwaves. His hands don't move; he makes no sound. But as he watches the screen, his brain learns to regulate itself in response to visual feedback from the computer. With practice, in about 20 one-hour sessions, his focus improves, his grades go up, and his social interactions become more positive and relaxed.
I woke up in a cheerful mood this morning because yesterday the results of a scientific study were published and they once again demonstrated that very strong benefits can be achieved through only 10 hours of Posit Science brain training. The cognitive benefits were not just seen in the tasks themselves, but in measures of [...]
What is your earliest memory? A frightening fall down the stairs? Blowing out candles on your third birthday? Or perhaps it is a trip to the hospital to visit a newborn sibling? Whatever the content, it is probably short and rather hazy. Adult recollections of infancy and early childhood are typically fragmentary. We forget so [...]
Do we really use only a small portion of our brain? If the answer to this question is yes, then knowing how to access the “unused” part of our brain should unleash untapped mental powers and allow us perform at top efficiency. Let’s examine the issue and attempt to get at the truth behind the [...]
Phineas Gage began the day of September 13, 1848 as a man remarkable only to those who knew him personally. He worked as the foreman of a railway construction gang in Vermont, where his group was preparing the bed for the Rutland and Burlington Rail Road. At just twenty-six years old, Gage was already a [...]
G.A.S. Spells Stress As with so many wondrous discoveries of science and medicine, it was by chance that Hungarian-born Hans Selye (1907-1982) stumbled upon the idea of the General Adaptation Syndrome (G.A.S.), which he first wrote about in the British journal Nature in the summer of 1936. The G.A.S., alternately known as the stress syndrome, [...]

Forget baseball, it turns out that watching TV is America's true national pastime. According to the 2007 findings of the American Time Use Survey, recently released by the Bureau of Labor Statistics, American men and women spend about half of their free time watching television. And, although this particular survey only included adults, more and more research suggests that our nation's children are following in their parents footsteps. 
Hundreds, if not thousands, of times a year a young athlete takes a hard blow to the head in the course of a high school, college, or an amateur sporting event. When this occurs, how do trainers and coaches determine if the athlete has received a concussion? If he or she has a concussion, is it cause for concern? And how is a decision made to return an athlete to playing contact sports? Over the past several years, a number of studies have shown that many different factors need to be considered in assessing sports-related concussions at all levels, from young children involved in Little League to professional athletes.
