What is self-efficacy and who developed the concept?

Self-efficacy, developed by Albert Bandura, is a person's belief in their ability to succeed at a specific task or in a specific situation. It differs from self-esteem, which is a general sense of self-worth. A person can have high self-esteem overall but low self-efficacy for mathematics. Self-efficacy influences whether people attempt challenging tasks, how much effort they invest, and how long they persist when facing obstacles. ---
