What is one of the signs of self-affecting behavior?

Closed posture is considered a sign of self-affecting behavior because it often indicates that an individual is feeling defensive, anxious, or withdrawn. When a person adopts closed postures, such as crossing their arms or legs, it is typically a physical manifestation of their inner emotional state. This behavior can suggest a desire to shield oneself from perceived threats or negative emotions, making the individual appear less open to communication and engagement. Such nonverbal cues can be crucial for security officers to recognize, as they may indicate distress or unease in an individual, allowing for appropriate responses to ensure safety and de-escalation of potential conflicts.
