Final answer:
Lucy demonstrates persistence by continuing to study after failing her practice quiz. Persistence signifies the trait of a motivated learner to work through difficulties. She also exhibits an internal locus of control by taking responsibility for her learning.
Step-by-step explanation:
Lucy's behavior most closely aligns with persistence. After failing her first practice quiz, she continues to study. This action demonstrates a commitment to understanding the material, regardless of initial setbacks. Persistence is an essential trait of a motivated learner, showing a willingness to persevere through challenges until the goal is achieved.
In relation to the reference information provided, self-regulation can be closely tied to a concept known as an internal locus of control, which suggests that a person believes they have control over their actions and outcomes. Lucy's decision to keep studying despite failing her quiz is a clear illustration of this psychology, as she is taking personal responsibility for her learning and outcomes.
