Mitigating Disruptions: Can Resuming an Interrupted Task Be Trained?

Abstract

Research has shown that with practice people improve on most tasks. It has also been made clear that over time interruptions become less disruptive. It is unclear whether the reduction in interruption disruptiveness is due to a general practice effect or specific to the interruption/resumption process. In this experiment, participants performed three sessions of a task with one, two, or three of the sessions containing interruptions. We found that in addition to all participants showing primary task improvement, those with more exposure to interruptions also showed improvement in dealing with the interruptions. Specifically, participants with practice on only the primary task did not show improvement with the interruptions. These results suggest that the mitigations of the disruptions are directly related to people getting better at handling the interruptions.
