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.
Driving Lessons
August 19, 2014
Many millions of us this summer took to the expressways of North America, and most of us reached our destinations safely. I find myself amazed at how few the accidents are when highways are crowded with hunks of metal traveling at 60, 70 and even 80 miles per hour.
There are three actions on a fast-moving expressway that jeopardize the health of travelers that are like three actions that jeopardize the health of organizations.
- First, if any number of drivers defies heavy traffic or wet pavement, then the well-being of all the others is at risk.
- Second, if just a single car ahead of a crowd of others slams on the brakes, then a chain reaction collision is likely to follow.
- Third, if a driver fails to look around and indicate the intention to change lanes, then those around that car must take evasive actions to escape trouble.
Likewise, organization leaders who move forward too fast without regard to their environment, leaders who suddenly slow down or stop their forward motion, and leaders who fail to consult with those around them and clearly signal their intentions to make a change, put their enterprise at risk.
Lessons for the office, learned on the road.
