Final answer:
An individual's sense of self-efficacy is the factor that contributes most to one's sense of self-efficacy. Self-efficacy is an individual's belief in their own capability to complete a task, which may be influenced by previous successful experiences and a person's level of confidence in their abilities. Self-efficacy affects how we approach challenges and reach goals, and it plays a significant role in motivating behavior.
Step-by-step explanation:
The question asks what factor contributes most to one’s sense of self-efficacy. According to Albert Bandura (1994), self-efficacy is an individual's belief in their own capability to complete a task. This confidence is developed through social experiences and affects how one approaches challenges and reaches goals. A key factor that contributes to an individual’s sense of self-efficacy is the interpretation of past experiences, particularly successful outcomes from previous similar tasks. Therefore, previous success in a related endeavor is a major contributor to one's sense of self-efficacy. Having an internal locus of control, as proposed by Julian Rotter, is also closely linked to self-efficacy, where an individual believes that the outcomes in their lives are the direct result of their efforts.
