We review both the theoretical and applied research on task interruptions. We provide a brief task analysis of interruptions and resumptions, discuss how and why they are disruptive, and show how multiple theories attempt to explain the interruption and resumption process. We also review a great deal of the empirical work and show how it fits into previous theoretical accounts. Finally, we discuss what factors make interruptions more or less disruptive as well as theory-based recommendations for reducing the disruptiveness of interruptions.
