本文介绍了现实工作任务中的任务复杂性和信息寻求活动的研究结果。重点是感知的任务复杂性，它是根据任务执行者对未来任务的先验知识确定的。这种对任务复杂性的看法与考虑任务不确定性和可分析性的研究密切相关。所考虑的信息寻求活动需要获取不同类型的信息以及随后使用不同类型的来源。研究数据主要通过（1）市政管理人员在履行日常工作职责过程中填写的自记日记（共78份任务日记）和（2）后续访谈收集。结果表明，信息类型和来源类型之间存在相对较强的关系。任务复杂性的影响使专家作为来源比其他人和所有类型的文献来源更具吸引力。
This article presents the research findings of a study on task complexity and information-seeking activities in real-life work tasks. The focus was on perceived task complexity, which was determined according to the task performers' prior knowledge about the task ahead. This view on task complexity is closely related to research considering task uncertainty and analyzability. Information-seeking activities considered were a need to acquire different types of information and the subsequent use of different types of sources. The research data were mainly collected by (1) self-recorded journals that were filled out by municipal administrators in the course of performing their ordinary work duties (altogether 78 task diaries), and (2) subsequent interviews. The results indicated that there is a relatively strong relationship between types of information and types of sources. The effects of task complexity made experts more attractive as a source than other people and all types of documentary sources.
