Final answer:
The question pertains to psychological defense mechanisms, including repression, reaction formation, regression, projection, rationalization, and sublimation, which individuals use to protect themselves from anxiety caused by unacceptable impulses or memories.
Step-by-step explanation:
The list provided refers to different defense mechanisms, which are psychological strategies used by the ego to protect an individual from anxiety arising from unacceptable thoughts or feelings. Repression is the blocking of anxiety-causing memories from consciousness, analogous to turning up the radio to ignore the noise of a car that needs fixing. Reaction formation is an ego defense mechanism in which a person expresses feelings, thoughts, and behaviors that are the opposite of their actual inclinations.
Regression is when an individual acts younger than their age, such as a child reverting to baby-like behaviors after the arrival of a new sibling. Projection involves refusing to acknowledge one's own unconscious feelings and instead attributing them to others. Two other mechanisms are rationalization, which is justifying behaviors by substituting acceptable reasons for the real, less-acceptable ones, and sublimation, which channels unacceptable impulses into socially acceptable activities.
