Abstract [en]

In complex dynamic work environments, the consequences of task interruptions on performance can put public safety at risk. If not designed carefully. current tools aiming to facilitate interruption recovery can instead hamper performance because of information overload. Although a simpler solution-the forewarning of an imminent interruption-has proven effective in static contexts, existing theories of task interruption do not clearly predict its impact on the resumption of dynamically evolving tasks. The current study examined the effects of a preinterruption warning in dynamic settings to develop a better understanding of task resumption and supplement current theoretical accounts. In a simulation of above-water warfare, scenarios were either uninterrupted, unexpectedly interrupted, or interrupted following an auditory warning. Behavioral, oculomotor, and pupillometric data regarding decision making, information processing. and cognitive load were computed before, during, and after each interruption (or the corresponding moment). Interruption warnings triggered a cognitively demanding preinterruption preparation that, in turn, speeded up postintemiption information processing and decision making and lowered cognitive load when resuming the interrupted task. These findings help to complement current theories of interruptions while showing that preinterruption warnings represent a promising way to support interruption recovery in complex dynamic situations.
