Final answer:
Self-efficacy is an individual's belief in their own capability to complete a task. It can be developed and is influenced by a person's emotional state. It is not related to prior experience.
Step-by-step explanation:
Self-efficacy is an individual's belief in their own capability to complete a task, which may include a previous successful completion of the exact task or a similar task. It is different from self-esteem because self-efficacy refers to confidence in one's abilities, while self-esteem is how one feels about oneself in general. Self-efficacy can be developed through social experiences, and it can vary depending on the situation. It is not related to prior experience, as self-efficacy can be influenced by a person's emotional state.
