The purpose of this paper is to report the findings of a literature review summary on the topic of the relationship of human psychological characteristics with athletic performance. Two research questions guided its development: (1) Is there any evidence that there is a relationship between individual human psychological characteristics and athletic performance? (2) If there is any evidence that there is a relationship between individual human psychological characteristics and athletic performance, is there further evidence that those individual characteristics translate in some way into group dynamics or attributes that may similarly influence team performance
