What does the term effusive suggest about an individual's behavior?

The term "effusive" refers to an individual's behavior characterized by an unrestrained or excessive display of emotion, particularly in terms of enthusiasm or affection. When someone is described as effusive, it indicates that they are openly expressive, often to the point of being overly enthusiastic, so much so that their feelings come across strongly and perhaps even overwhelming. This aligns perfectly with the notion of being extravagantly demonstrative; such individuals may pour out their feelings exuberantly and openly, whether in a celebration or an expression of gratitude.

The other options do not align with the meaning of "effusive." For instance, being demure and reserved implies a sense of shyness or modesty, which is the opposite of the outward expressiveness associated with effusiveness. Expressing criticism does not inherently connect with the emotional exuberance suggested by effusive behavior. Finally, being neutral and detached signifies a lack of emotion or involvement, further contrasting with the over-the-top expressiveness that defines someone who is effusive.
