摘要：	A fundamental aspect of multiple task management is attending to new stimuli and integrating associated task requirements into an ongoing task set this is 'interruption management' (IM). Anecdotal evidence and field studies indicate the frequency and consequences of interruptions, however experimental investigations of mechanisms influencing IM are scarce. Interruptions on commercial flightdecks are numerous, of various forms, and have been cited as contributing factors in many aviation incident and accident reports. This research grounds an experimental investigation of flightdeck interruptions in a proposed IM stage model. This model organizes basic research, identifies influencing mechanisms, and suggests appropriate dependent measures for IM. Fourteen airline pilots participated in a flightdeck simulation experiment to investigate the general effects of performing an interrupting task and interrupted procedure, and the effects of specific task factors (1) modality (2) embeddedness, or goal-level, of an interruption (3) strength of association, or coupling-strength, between interrupted tasks (4) semantic similarity and (5) environmental stress. General effects of interruptions were extremely robust. All individual task factors significantly affected interruption management, except 'similarity.' Results extend the Interruption Management model, and are interpreted for their implications for interrupted flightdeck performance and intervention strategies for mitigating their effects on the flightdeck.
