How does stress exposure affect accuracy and decision-making in DT?

• A. It always improves reaction speed.
• B. It can narrow attention, speed up or slow down reactions, and affect perception; training and risk awareness help mitigate.
• C. It has no impact on perception or decisions.
• D. It only affects physical strength, not mental processes.

Answer: (B)

Stress exposure changes how you process information and make decisions during defensive tactics. When under pressure, your arousal level rises, which can narrow your attention to the most immediate threat cues. That perceptual narrowing can make you react quickly to familiar, simple tasks, but it can distort or miss less obvious information and alter how you evaluate risks. Reactions can speed up or slow down depending on the task and your level of training; in high-stress situations, complex decisions are more prone to error even as simple, practiced responses can be executed more quickly. Training and risk awareness help counter these effects by building automatic responses, improving cue recognition, and providing decision-making guides that you can rely on under pressure rather than relying on slow, conscious deliberation. With realistic stress exposure in training, you learn to stay more visually and cognitively available, calibrate your responses to actual risk, and maintain more consistent performance across different stress levels. The other statements don’t fit because they either overlook cognitive and perceptual changes, claim universal improvements, or ignore mental processes altogether.
