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.
Leadership Communication
December 3, 2013
“We’ve got the weather,” the man said. And for years, my wife and I have wondered what he meant.
We had been walking in Dublin, Ireland and paused to photograph the huge wooden doors of an aging church building, when an elderly man on the sidewalk greeted us with those few words.
Did he mean the weather was bad because it was raining? Or, as we think more likely, was he saying the weather was good because it was a mild day with a gentle breeze and only a light rain?
My wife and I still recall that day in Dublin, that brief encounter, whenever we hear people make statements that could be interpreted in exactly opposite ways.
Speakers often say one thing and mean another, sometimes intentionally, sometimes innocently. Listeners often misinterpret what was stated because they had something different on their minds or expected something different to be said.
All of this and more adds to the difficulty of communicating effectively, whether between two people or within a team or organization.
Leadership communication attempts to minimize these misunderstandings; and an effective tactic for doing so is to have listeners restate what they believe they heard the leader say.
Communicating messages clearly and repetitiously is a leadership essential; but so is providing opportunities for others to repeat those messages. This leads not only to more precise communication, but also to more pervasive and powerful messages.
