When in danger humans are similar to a deer in the headlights

Standing still when a threat is detected is a defensive, protective reaction. This ancestral and automatic behavior allows the prey to stay unnoticed by a potential predator. A new study published in Psychophysiology finds that humans, like many other complex animals, freeze when encountering a threat. The mere picture of an injured or mutilated human induces this reaction. When viewing these unpleasant images, the study's participants froze as their heart rate decelerated and amount of their body sway reduced. The authors found that this abrupt reaction, so critical for the survival of some animals, has stayed with humans.

Forty-eight male volunteers stood barefoot on a stabilometric platform, to measure balance and body sway, and viewed twenty-four pictures from three different categories. They were: pleasant (sports), neutral (objects), and unpleasant (injured or mutilated humans). Posturographic and electrocardiographic recordings were collected. The author found a significant reduction in body sway along with increased muscle stiffness following the unpleasant/mutilation block of pictures compared to the neutral pictures. The number of heartbeats per minute was also lower after viewing the mutilation pictures than after looking at the others. "This pattern resembles the 'freezing' and 'fear bradycardia' seen in many species when confronted with threatening stimuli, mediated by neural circuits that promote defensive survival," author Eliane Volchan explains.
