Weiner, an American psychologist, believes that people's analysis of the reasons for the success or failure of behavior can be summarized into six reasons: ability, effort, task difficulty, luck (opportunity), physical and mental state, and external environment. Among them, ability attribution refers to an internal, stable and uncontrollable attribution that individuals evaluate their competence according to their own situation. Xiaoqing attributed her poor math performance to her stupid brain, which belongs to the attribution of ability factors, that is, internal, stable and uncontrollable attribution.
