Self-efficacy: refers to the individual's speculation and judgment on whether he has the ability to complete a certain behavior. According to this theory, even if people's behavior does not strengthen themselves, they may take the initiative to carry out that activity because they expect the efficacy of the result of their behavior. Self-efficacy theory has overcome the tendency of traditional psychology to emphasize desire and knowledge over emotion, and it is of great scientific value to study people's motivation by combining people's needs, cognition and emotion. But so far, a relatively complete and unified theoretical framework has not been formed. Self-efficacy was put forward by Bandura, which refers to the subjective experience that individuals think they can successfully complete a certain behavior. Self-efficacy affects individual behavior orientation and mood. If a person has a high sense of self-efficacy for a certain behavior or task, he will be full of emotions and confidence to carry out this behavior and complete this task; If you have a low sense of self-efficacy, you will avoid such behaviors and tasks.
