ABSTRACT
Most people studying naturalistic decision making (NDM) would likely describe themselves as researchers of judgment and/or decision making. In the beginning of my career, I described myself as a researcher of problem solving and memory. However, subsequent studies on the superior per formance of experts in chess, music, and sports has led me to question the merits of such traditional approaches, that is, attempts to study psychologi cal activities in their purest, most abstract and generalized form. In this chapter, I explore the salient issues surrounding my study of expertise in many divergent domains and the implications this research has on how we as researchers view and conduct our psychological research efforts.
