Operators working in extreme environments are often confronted with task interruptions. These interruptions tend to impair performance, which can represent a threat to public safety. Most of the tools designed to aid task resumption in such dynamic contexts are post-interruption solutions consisting of providing information about missed events once the interruption is over. The goal of the present study is to test whether a pre-interruption solution consisting of warning operators of an impending interruption can also facilitate interruption recovery. We employed a microworld simulating above-water warfare and compared primary task recovery following an interruption that could either be notified (8 s before it takes place) or not. Results revealed enhanced post-interruption decision accuracy and speed when providing foreknowledge of the imminent interruption. These findings suggest that a pre-interruption warning, which has already proven effective in static contexts, can also support interruption recovery in dynamic settings.
