Which behavior is indicative of panic during a crisis?

The behavior that signifies panic during a crisis is being physically immobile. This response is often associated with a state of extreme fear or anxiety, where an individual may feel overwhelmed and unable to act. In a crisis situation, this immobility can reflect a fight-or-flight reaction where the person freezes instead of responding actively. Such a reaction can happen when the brain perceives the threat as being so intense that it triggers a sense of paralysis rather than an aggressive or escape response.

Although other behaviors like sobbing for no apparent reason, difficulties with falling asleep, and startling to loud noises and touch can indicate distress or emotional upheaval, they do not specifically signal panic as directly as physical immobility does. While emotional expressions and heightened sensitivity to stimuli can occur during stressful situations, they may not necessarily represent an acute panic response, which is characterized by an individual being unable to move or respond in the moment due to overwhelming fear.
