Final answer:
Overcontrolled behavior is a result of internalizing problems. Jane's belief about her bad grade due to her professor's perceived dislike of her illustrates an external locus of control. Understanding various defense mechanisms is key to recognizing how individuals cope with inner conflicts and external pressures.
Step-by-step explanation:
Undercontrolled behavior is a result of externalizing problems, while overcontrolled behavior is a result of 1) Internalizing problems. These terms describe how individuals regulate their behaviors and emotions, with undercontrolled individuals often displaying externally-focused behaviors such as aggression or hyperactivity, and overcontrolled individuals displaying internally-focused behaviors such as excessive worrying or shyness.
Jane's belief that she received a bad grade on her psychology paper because her professor doesn't like her is indicative of an external locus of control. This refers to the belief that outcomes are controlled by external factors rather than one's own actions. Conversely, an internal locus of control reflects the belief that one has personal control over outcomes.
Understanding the defense mechanisms such as displacement, along with concepts like the id, ego, and superego in Freudian psychology, is crucial for insight into personality structure and the unconscious mind. Defense mechanisms are unconscious strategies that the ego uses to deal with conflict between the id and reality, often leading to mental health issues if they become overutilized.
