Here are the quotes about the tests which are near the bottom of the article:
For years, NBA teams have used the Caliper Profile to evaluate potential draft picks. The Caliper is a personality profile used by numerous corporations and organizations to measure one's capacity to excel in specific situations. Over the past 24 years, Caliper has assessed more than 20,000 athletes, including NBA players from Detroit, San Antonio, Denver and Phoenix. Colangelo has long been sold on the system. When he heard how Bargnani measured up, he nearly dropped the phone.
The test showed that Bargnani is virtually oblivious to what others think of him. And his tremendous ability to block out such potentially negative pressures enables him to focus completely on the task at hand. So the expectations and anxieties that come with being the No.1 pick, or the only Italian-born player in the league, or even taking a game-winning shot, don't even register with him.
I doubt any teams in the CFL use this test, and I think it would be perfect for scouting young q.b's to see if they have the mental toughness to make it in the pro's, or even a good test to assess coaches.
