Which term describes post-threat tunnel vision?

• A. Lateral tunnel vision
• B. Threat overlap confusion
• C. Post-threat tunnel vision
• D. Split-second decision bias

Answer: (C)

Post-threat tunnel vision describes the lingering narrowing of attention that can persist after a threat has been controlled. During danger, the brain prioritizes threat-related information and suppresses peripheral input. Once the threat is over, adrenaline and related arousal can keep attention locked onto a narrow field, making it harder to notice details around you, assess the full scene, or recall what happened. This term precisely labels that continuation of tunnel vision beyond the moment of threat, which is why it’s the best fit. Other phrases don’t capture this specific aftereffect: lateral tunnel vision isn’t a standard term for this phenomenon, threat overlap confusion isn’t recognized terminology for post-threat perception, and split-second decision bias describes rapid judgments rather than the perceptual narrowing that persists after the threat ends.
