Super Smash Brother Ultimate esports tournaments provide a promising space to study how competitors react to failure at a fine-grain level. This project uses conceptualizations from psychology of how individuals react to failure, coined mastery orientation, to probe into how competitors react when encountering moments of failure in-game. This will focus on the in-game behaviors that competitors exhibit in reaction to these moments, comparing them to traditional measures of mastery orientation. This work promises to develop our understanding of how competitors navigate these failure-rich environments, and how they use failure as information that leads to eventual success.
