Attribution theory: a social cognitive theory about individuals explaining the reasons of others or their own behavior. The purpose is to control people's environment and behavior by analyzing and speculating the causal relationship of behavior. How the perceiver judges and explains the reasons of others' and their own behaviors is the basic problem to be solved by attribution theory. It tries to explain various attribution principles according to different attribution processes and their functions, so as to understand, predict and control their environment and their accompanying actions. 1972 Wiener put forward his own attribution theory based on Hyde's attribution theory and Atkinson's achievement motivation theory. The reasons for Wiener's basic consent behavior can be divided into internal and external causes, and he also proposed a new dimension, that is, the reasons can be divided into temporality and stability. The main points of Weiner's attribution theory are: personality differences and success or failure experiences affect his attribution; A person's attribution to the last achievement will affect his expectations, emotions and efforts for the next achievement. Personal expectations, emotions and efforts have great influence on achievement behavior.
