The skill Zimmerman and Kitsantas chose was a volleyball serve. They gathered a range of expert players, club players, and novices, and asked them how they approached the serve: their goals, planning, strategy choices, self-monitoring, and adaptation—twelve measures in all. Using the answers, they predicted the players' relative skill levels, then had the players execute their serve to test the accuracy of their predictions. The result? Ninety percent of the variation in skill could be accounted for by the players' answers.
