Final answer:
The correct term for a defense mechanism that shifts emotions from the original object to a more acceptable substitute is displacement. This is distinct from projection, where one's feelings are attributed to others.
Step-by-step explanation:
A defense mechanism in which emotions, ideas, wishes, or impulses are unconsciously shifted from the original object to a more acceptable substitute is known as displacement. This defense mechanism involves transferring inappropriate urges or behaviors onto a more acceptable or less threatening target. In contrast to projection, which is when a person refuses to acknowledge their own unconscious feelings and instead sees those feelings in someone else, displacement acts as a psychological defense that reduces anxiety by redirecting emotions to a safer substitute.
