Perceived Task Characteristics and Employee Performance: A Literature Review,
回顾了13项关于感知任务范围与员工绩效之间实证关系的研究，发现结果矛盾且不确定，多数研究对员工绩效的测量不够充分，且可能存在反向因果关系，呼吁进一步的理论阐释和改进研究设计。
We review 13 studies dealing with empirical relationships between perceived task scope and employee performance. Results from these studies are contradictory and inconclusive. Most studies use less than adequate measures of employee performance. Moreover, although a causal relationship is assumed, reciprocal or reverse causality may exist. There is a clear need for further theoretical explication and improved laboratory and field research aimed at enhancing both construct validity and substantive considerations.
