Head Trauma and Learning
November 23, 2012
Researchers at my alma mater have joined their voices to the growing chorus of concerns about the effects of repeated blows to the head.
A study of the cognitive effects of head impacts on members of Dartmouth College football, hockey, track, crew and Nordic ski teams compared before and after season results on learning and memory skills. Participating athletes also came from Brown and Virginia Tech.
-
22 percent of athletes in contact sports had lower results on learning and memory skills tests after their season.
-
Only 4 percent of athletes in non-contact sports posted lower test results.
The researchers caution that it is unknown at this point how long these negative effects may last, but they also note there is some correlation between test results and how hard the athletes were hitting heads.
This adds to the mounting evidence that rules writers, program sponsors, coaches and officials must look for and implement a variety of measures to reduce the frequency and severity of head impacts in both practice and competition in all sports.
We Need A Picture
December 18, 2012
One of our family traditions is to start and complete a new puzzle each Thanksgiving Day. This past year’s 1,000-piece project tested our guests’ perseverance and, technically, it wasn’t completed on Thanksgiving, but just after 1 a.m. on the next day with only two of the original 16 guests still on task.
As is customary, the cover of the box in which the puzzle came provided a picture of the finished work. Those working the puzzle kept passing the box top around to get closer looks at the specific portions of the puzzle that had their attention.
At one point my son mentioned how incredibly difficult it would be to complete a complicated puzzle without any picture.
Which caused me to consider that trying to solve any puzzle – any problem – is made almost impossibly difficult without a clear picture of what the solution should look like. To put together the pieces of the solution to a problem requires at least some vision of the solution.
