Abstract: Looking at other people allows us to collect information about them, but it can also reveal our attentional state when we would rather conceal it. We report that individuals spontaneously employ sustained covert monitoring, rather than direct looking, when evaluating the actions of a live stranger. In contrast, individuals look directly at the actions of a stranger on video. We argue that the ability to secretly monitor live others without executing a look towards them is an important process that compensates for the risk of looking directly during certain social situations. Covert monitoring allows people to avoid visually communicating to others that they are the focus of one's attention. This represents a previously undocumented function of covert attention outside of the laboratory. It suggests that the relationship between covert attention and looking is dynamic and likely to be foundational to the successful navigation of real-world social situations.
