Final answer:
Emotional contagion can occur with both positive and negative emotions, and using metacognition can help manage strong emotions.
Step-by-step explanation:
The statement that emotional contagion only occurs when negative emotions spread from one person to another is false. Emotional contagion refers to the phenomenon where people mirror the emotions they observe in others, which can be both positive or negative.
When faced with strong emotions from oneself or others, it's beneficial to use metacognition, which is the process of thinking about one's own thought processes. Metacognition allows individuals to reflect on and understand the source of the emotions they are experiencing and develop strategies to manage them effectively. This form of emotional self-regulation can help mitigate the spread of strong emotions and maintain emotional balance within a group or an individual.
