“…In an arm wrestling study (Nelson & Furst, 1972), the weaker subjects won 10 of 12 matches when both contestants incorrectly believed the weaker person to be stronger than his opponent; when the contestants correctly identified the weaker contestant, the stronger subjects won all 12 matches. Other studies have shown that positive self-talk improves the performance of basketball players (Kendall, Hrycaiko, Martin, & Kendall, 1990), skiers (Rushall, Hall, Roux, Sasseville, & Rushall, 1988), and swimmers (Rushall & Shewchuk, 1989). It is plausible that the positive reinforcement provided by an athlete's success increases self-efficacy and, thereby, enhances performance.…”
