The paper Help or flight? Increased threat imminence promotes defensive helping in humans has been accepted for publication in Proceedings of the Royal Society B. Authored by Joana Vieira, Sabine Schellhaas, Erik Enström, and Andreas Olsson.
We demonstrate that high threat imminence (immediate risk of another person receiving a shock) facilitated helping behavior. Our findings suggest that, just like higher threat imminence fosters active avoidance from self-directed threats (fight-or-flight), it may promote helping when others are under threat.
