Abstract
An archival study of aggression using a refined definition based upon certain types of norm violations in ice hockey was conducted to explore whether aggressive responses can be generalized over time and place. While differences for an entire team's performance over 7years found trends but no significant differences, more refined analysis reported differences. When subgroups of low versus high aggressive players were compared, significant differences were found. Aggression increased over time and was more evident at home than away. An exception occurred when initial aggression was high and a postulated self-regulatory control decreased subsequent aggression.
