Which of the following is NOT one of the four reactions to stress?

In understanding the reactions to stress, the common responses identified are fight, flight, freeze, and submit. The correct choice here is "submit," as it is often viewed as a form of yielding or giving in to the stressor rather than a typical stress reaction. The "fight," "flight," and "freeze" responses are well-documented physiological reactions to perceived threats or stressors.

When faced with a stressful situation, individuals may react by fighting (confronting the threat), fleeing (escaping from the threat), or freezing (becoming immobilized). However, "submit" is not traditionally classified within the primary reactions to stress but can be seen as a behavioral response stemming from a sense of defeat or resignation in a situation. This delineation highlights the importance of understanding the most recognized and studied responses to stress, helping individuals and law enforcement professionals to recognize their own reactions under pressure and prepare accordingly.
