Answer:
True.
Step-by-step explanation:
Perceived threat is the perceived risk of harm or loss resulting from a particular situation or event, and it is influenced by both the perceived severity (the magnitude of the harm or loss that is expected to result if the event occurs) and the perceived vulnerability (the perceived likelihood of the event occurring and affecting the individual). Since both perceived severity and perceived vulnerability can change over time, perceived threat is indeed a dynamic concept that can vary in different circumstances.
