The purpose of this study was to examine the influence of personality on causal attributions of choking in sport. We performed questionnaire surveys on 358 college and graduate students involved in sports, and performed covariance structure analysis to examine relationships between latent variables. We found that extroversion and emotional stability were personality traits associated with causal attributions of choking. Furthermore, the fear of failure, being conscious of others, and a weak personality were causative factors of choking. Athletes with low emotional stability attributed the causes of choking to fear of failure, being conscious of others, and a weak personality. Athletes with low extroversion attributed the causes of choking to a weak personality. Previous studies have not addressed how individual differences in personality traits influence choking in sport. Our findings suggest that deepening the understanding of choking can be facilitated by considering both personality traits and causative factors.
