In Freud's defense mechanisms, which one can be described as shifting feelings onto another person or object?

Displacement is indeed the defense mechanism that involves shifting feelings or impulses from one person or object onto another. In this process, an individual may take out their frustrations or negative emotions on a less threatening entity rather than confronting the actual source of their distress. For example, if someone is angry at their boss but feels they cannot express this anger openly, they might instead vent their feelings on a family member or even an inanimate object, like breaking something in their home. This mechanism helps the person cope with their emotions without addressing the underlying issue directly.

In contrast, regression is characterized by reverting to earlier stages of development when faced with stress. Projection involves attributing one's own unacceptable feelings or thoughts onto someone else, thus seeing those traits in others rather than in oneself. Rationalization allows individuals to justify or excuse their behaviors or feelings by offering reasonable explanations, rather than acknowledging the real motivations. Each of these mechanisms serves a different purpose, but displacement specifically relates to the act of redirecting emotions onto something or someone else.
