Time for reflection 1 Running head: Polychronicity Time for Reflection: A Critical Examination of Polychronicity

Time for reflection 2 Both researchers and practitioners are increasing their attention to the multitasking demands of contemporary work contexts, and previous work suggests polychronicity plays a central role in the motivation of individuals to perform multiple tasks simultaneously. However, our detailed examination of existing literature reveals a wide range of conceptualizations and operationalizations of this construct, as well as incongruent results concerning the effects of polychronicity on behavior and performance. In this paper, we develop recommendations for defining and measuring polychronicity more precisely, we examine and compare existing work on predictors of polychronicity, and we address the equivocal relationship between polychronicity and performance. We conclude with implications for future research
