“…Humans, similar to other animals, react to threatening situations with neurophysiological changes that influence decision making (Fanselow & Lester, 1988;Roelofs, 2017). Whereas existing work on threat responding has mainly considered individual decision-making (Blanchard, Griebel, Pobbe, & Blanchard, 2011;Bradley, Codispoti, Cuthbert, & Lang, 2001;Fanselow & Lester, 1988;Roelofs, 2017), threats arising from climate change, contagious diseases and terrorist attacks typically affect and are experienced by groups of individuals whose behavioral responses influence not only their own, but also each other's welfare (Gross, Veistola, De Dreu, & Van Dijk, 2020;Van Lange & Rand, 2021). Unfortunately, however, we poorly understand how threat exposure and concomitant neurophysiological responses modulate group functioning.…”
