Which of the following is a common characteristic of phobias?

Extreme avoidance of the feared object is a hallmark characteristic of phobias. Individuals who experience phobias often go to great lengths to avoid encountering the specific object or situation that triggers their intense fear. This avoidance behavior is not just a simple preference; it is often driven by overwhelming anxiety or panic that arises in the presence of the phobic stimulus.

For example, a person with a fear of spiders (arachnophobia) may refuse to enter places where they believe spiders might be present or might go to great lengths, like checking corners or using certain approaches to avoid any possible encounter. This avoidance can significantly interfere with a person's daily life and functioning, leading them to modify their routines and activities to prevent exposing themselves to their fear.

While immediate panic attacks are commonly associated with phobias, the characteristic that best defines the disorder is the extreme avoidance behavior. Severe depression following exposure and uncontrollable laughter are not recognized as common characteristics of phobias and do not align with the typical responses exhibited by individuals living with these anxiety disorders.
