Which symptom may indicate hyperarousal trauma effects?

Increased aggression can be a significant symptom of hyperarousal, particularly in individuals who have experienced trauma. Hyperarousal is characterized by a heightened state of emotional and physical readiness, leading to symptoms such as irritability, heightened startle response, and often, increased aggression. This is a response to feeling threatened, where a person may react more vigorously to perceived dangers, stemming from an inability to regulate emotional responses effectively due to past trauma.

The other options reflect responses that are not consistent with hyperarousal. Improved concentration and social engagement typically indicate a more stable emotional state, which is not characteristic of hyperarousal. Similarly, relaxation and calmness are directly opposing states as hyperarousal includes feelings of tension and anxiety rather than tranquility. Understanding this differentiation helps in recognizing the various ways trauma can manifest, particularly in how individuals may react in high-stress situations.
