Final answer:
Hannah's belief that she commands her own fate is described by Julian Rotter as a 'locus of control,' specifically an internal locus of control, where individuals believe their actions directly influence their outcomes.
Step-by-step explanation:
Hannah's belief:
Hannah believes that she is in command of her own destiny, indicating a belief that is referred to as locus of control by Julian Rotter. This term defines our belief in the power we have over our lives, with an internal locus of control illustrating the conviction that our efforts greatly influence our outcomes, while an external locus of control paints a picture of our life's outcomes being determined by other forces such as luck, destiny, or the actions of others.
People with a high internal locus of control are more likely to take responsibility for their actions and outcomes, as opposed to those with an external locus of control who are prone to attribute their success or failure to factors outside their influence. For example, if Hannah believes that she is in command of her own fate, she has an internal locus of control. On the other hand, if she believes that her fate is determined by luck, fate, or other people, she has an external locus of control.
