Multitasking

Abstract Multitasking has become increasingly prevalent, especially as we continue to incorporate more and more new media technologies into our daily activities. This essay first identifies trends in the availability and use of media devices in daily life and multitasking behaviors related to such trends. Second, given the general consensus that multitasking impairs performance outcomes, recent multitasking trends call for greater research attention to the subject. We outline the historical perspectives on cognitive structures and processes related to a human's general ability to multitask, culminating with the more recent threaded cognition theory. Third, we present two new research directions on multitasking. One is the exploration of long‐term consequences of multitasking behaviors, such as their impacts on cognitive functions, and dynamic changes in individuals' needs and multitasking behavioral changes over time; the other is a cognitive dimensional framework for defining multitasking, which may offer a means to reconcile findings across various multitasking research paradigms, and also to guide designs of multitasking technologies and environments. Finally, looking to the future, we propose several ways to advance the research on multitasking.
