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.

It's probably a sign of my age and stage in life, but I cannot get in any habit of consuming information by podcasts. If I want to absorb facts, figures and ideas that I can retain for later use, I have to receive that information in writing and be free to highlight phrases and make notes in the margins of that document.
I'm so committed to or conditioned by this process that I even need to print online articles so I can take my pen to the text to help me embrace the author's message or mold it into mine. I remain an ardent advocate for the medium of printed words.
I'm apt to remember portions of long-form printed pieces much longer than texts and tweets; and if a printed piece is very good, or at least speaks to me, I develop a relationship with it through my underlining and notes, and it stays with me longer than audio and even video media.
My preferences are demonstrated in the continuing commitment the Michigan High School Athletic Association has made to providing printed souvenir programs at the finals for most of its postseason tournaments as well as to a glossy, issues-oriented magazine (benchmarks) and hard-copy printed curriculum for our in-person coaches education program (CAP) when many of its counterpart organizations across the US have moved to electronic alternatives for these services.
I'm all for reducing the use and waste of paper for environmental reasons; but for educational purposes, print on paper still has a place in the modern world of communications clutter. Perhaps a never more important place.
