Final answer:
A person who avoids challenging tasks might lack self-efficacy, which is the belief in one's ability to succeed. High self-efficacy individuals embrace challenges, while those with low self-efficacy tend to shy away from them.
Step-by-step explanation:
Lack of self-efficacy may be indicated by a person who avoids challenging tasks because they doubt their capability to succeed. Self-efficacy refers to one's belief in their ability to manage future situations and accomplish goals. People with high self-efficacy see challenges as tasks to be mastered and are committed to their activities, while those with low self-efficacy tend to focus on failure, doubt their skills, and often avoid difficult tasks altogether.
Julian Rotter's concept of locus of control is related but distinct, describing whether a person attributes outcomes to their own actions or external forces. Building resilience can enhance self-efficacy, helping individuals to adapt and persevere through adversity, which may ultimately affect one's success in various aspects of life, such as academic achievements or career advancements.
