Defensive Tactics (DT) Practice Test

Perceptual time distortion is the phenomenon where your sense of how fast or slow events are happening changes under stress. When adrenaline and heightened arousal flood your system, your brain processes sensory input differently, so durations can feel longer or shorter than they actually are. This explains why a rapid sequence of actions might seem to unfold in slow motion, giving you the impression you have more time to react, or why other moments feel quicker than they really occurred. In defensive tactics, recognizing this helps you train to rely on practiced responses rather than purely on how time seems to pass. The other terms don’t describe this timing change: one refers to a general alert state, another to where you primarily focus your eyes, and the last to memory gaps after a critical incident.
