The Effects of Interruptions, Task Complexity, and Information Presentation on Computer‐Supported Decision‐Making Performance
实验研究发现中断对简单任务有促进作用，但对复杂任务有抑制作用；空间信息呈现能缓解中断影响，而符号呈现则不能。
ABSTRACT Interruptions are a frequent occurrence in the work life of most decision makers. This paper investigated the influence of interruptions on different types of decision‐making tasks and the ability of information presentation formats, an aspect of information systems design, to alleviate them. Results from the experimental study indicate that interruptions facilitate performance on simple tasks, while inhibiting performance on more complex tasks. Interruptions also influenced the relationship between information presentation format and the type of task performed: spatial presentation formats were able to mitigate the effects of interruptions while symbolic formats were not. The paper presents a broad conceptualization of interruptions and interprets the ramifications of the experimental findings within this conceptualization to develop a program for future research.
