Resumo(s)
A considerable volume of animal research on detecting threat and foraging reveals that the co-presence of
conspecifics reduces vigilance and enhances foraging. Monitoring threat is an adaptive process and is of considerable
relevance to humans. It is therefore important to understand how the presence of others influences
threat monitoring - namely vigilance - and consequently the capacity to detect threats. We examine this with a
novel paradigm, that simulates a “foraging under threat” situation, with an eye-tracker (allowing the examination
of the allocation of attention). Our results show, as predicted, that participants in the individual
condition (versus co-presence) allocated more attentional resources to scanning the environment and thereby
sacrificing foraging, which increased their likelihood of detecting threatening events. Thus, the presence or
absence of others modulates vigilance strategies in humans. These findings highlight the heuristic value of
animal vigilance models to understand humans threat monitoring with considerable applied relevance.
