Journalists and media commentators have, at times, provided a glimpse of what made these athletes great, but few scientific studies have been conducted on the psychology of our champions. To find out more about what psychologically makes Olympic champions so great, we recently conducted an investigation of some of our most successful U.S. Olympians. In our study, 10 of the most successful U.S. Olympic champions participated in confidential interviews for the purpose of determining their psychological characteristics and how the characteristics developed over time. To provide additional perspectives regarding these issues one coach for each athlete as well as a parent, guardian, or significant other were also interviewed. Finally, a battery of psychological tests were administered to athletes to further identify their psychological characteristics. The 10 champions represented nine different Olympic sports. These athletes had competed in one or more Olympic Games between the years of 1976 and 1998 with an average of 2.4 Olympic Games each (range one to four Games). The athletes who participated in this study were selected by an analysis of Olympic Games performance records and availability. Among them, these athletes won 32 Olympic medals (28 gold, three silver, one bronze). Four of the athletes participated in the Olympic Winter Games while the remaining six athletes were summer Games participants. Six male and four female athletes were interviewed. Characteristics of Champions These champions exhibited a number of impressive psychological characteristics. Some of the more important attributes are highlighted below.
