ABSTRACT

Applications of cognitive research to the design of more effective operational and training systems have been informed by two alternative perspectives on semiotics—the dyadic and the triadic perspectives. We will make the case that the triadic perspective provides a more comprehensive framework for cognitive science, which is especially valuable when considering the pragmatic implications for designing socio-technical systems (for example, designing virtual environments for training). However, the introduction of a “third body” into the cognitive system raises important challenges for both science and application. In this chapter, we will consider some of the challenges of the triadic (three-body) system and will suggest how synthetic task environments can help researchers address these challenges.
