DETERMINANTS AND CONSEQUENCES OF TASK UNCERTAINTY: A LABORATORY AND FIELD INVESTIGATION
通过实验室和现场两项研究，发现任务不确定性的感知取决于例外事件的数量和可分析性，且例外感知与搜索难度对沟通和决策行为有不同影响，建议用两个源构念替代任务不确定性概念。
ABSTRACT This article presents evidence and argument concerning the utility of the concept of task uncertainty for organization theory and practice. The results from two studies, one field and one laboratory, are reported. The results support the hypotheses that: (1) perceptions of task uncertainty are a simple function of the number and analysability of exceptions encountered, and (2) perceptions of task exceptions and search difficulty have distinct relationships with behaviours of interest (communication and decision‐making). Given these two findings, it is argued that the concept of task uncertainty should be replaced by the two source constructs.
