This study shows that human defensive neural circuits, not just empathy, drive helping behavior when others are in danger.

This study uses fMRI to show that observational fear learning from friends and strangers produces similar brain activity patterns, suggesting familiarity does not enhance threat learning.

This study examines the effect of oxazepam on cognitive reappraisal in healthy males, finding reduced unpleasantness ratings to negative images but no impact on reappraisal effectiveness.

This study investigates observational fear learning by having observers watch a friend perform a fear-conditioning task in real time, finding that emotional reactions and contingency learning both contribute to the process.

The paper shows that physiological synchrony between demonstrators and observers predicts stronger observational threat learning in humans.
