ABSTRACT
Macro-level trends such as globalization, technology, demographic shifts, and alternative work structures have led researchers and practitioners to challenge traditional defi nitions of individual work performance (Ilgen & Pulakos, 1999). Two major ways in which these defi nitions have shifted include performing in interdependent and uncertain work contexts (Griffi n, Neal, & Parker, 2007). Thus, a complete understanding of performance must address how individuals adapt to ever-changing situations and how individuals perform within given social settings and social systems. In this chapter, we explore such expanded defi nitions of work performance by considering what we know (and what we do not know) about adaptive and organizational citizenship-related behaviors and how this knowledge might be used to inform selection.
