Past research recognizes the important influence of individual beliefs on technology acceptance and use. This line of research has also identified a variety of factors that drive the formation of these beliefs. One category of variables that has not received much attention in this research stream consists of individual preferences, in particular time-use preferences. In the current study we add to the literature on technology acceptance, and belief formation in particular, by introducing and empirically testing a new construct labeled computer polychronicity, which captures individuals’ time-use preferences regarding IT. Computer polychronicity is positioned in this study as a key driver of perceived usefulness, mediating the effects of computer anxiety and computer playfulness. Overall, the results support the notion that preferences play important roles in the formation of technology-related beliefs.
