Which of the following is a sign of emotional lability?

Emotional lability refers to rapid and often exaggerated changes in mood that are typically inconsistent with the situation at hand. It can manifest as inappropriate emotional reactions, where an individual may express emotions that seem disproportionate to their circumstances, such as laughing at a sad event or crying over something that typically wouldn’t evoke such a reaction.

This is a significant characteristic of emotional lability, distinguishing it from more stable emotional responses. In contrast, steady emotional responses, consistent mood changes, and controlled emotional responses indicate a level of emotional regulation and stability that does not align with the definition of emotional lability. Therefore, inappropriate emotional reactions correctly reflect the unpredictable and often extreme nature of this condition.
