Attribution theory examines how people explain or attribute their success and failure in sports and physical activities. People commonly attribute outcomes to internal factors like ability and effort or external factors like task difficulty and luck. According to Weiner's attribution model, attributions can be categorized based on whether their perceived cause is internal or external, and whether the cause is considered stable or unstable. Weiner's model aims to understand how attributions for success and failure can impact emotions, behavior, and future participation.
