Which characteristic is commonly seen in someone employing Reaction Formation?

The characteristic of disguising true emotions with visible enthusiasm is a hallmark of Reaction Formation. This defense mechanism involves expressing attitudes, feelings, or behaviors that are the opposite of one's true, often uncomfortable or distressing emotions. For instance, if someone feels deep-seated anger or anxiety about a situation, they might outwardly display joy or excitement as a way to mask those feelings. This behavior helps individuals manage internal conflicts and societal expectations, allowing them to present a socially acceptable demeanor while internally struggling with different emotions.

In contrast, the other options do not align with the core principles of Reaction Formation. Authenticity in expressing feelings contradicts the essence of the mechanism, as Reaction Formation is about masking true feelings rather than expressing them honestly. Apathy towards social interactions does not demonstrate the exaggerated enthusiasm characteristic of Reaction Formation, and openly admitting personal struggles represents a direct acknowledgment of true feelings rather than the defensive stance taken in Reaction Formation.
