ABSTRACT
The naturalistic study of expert decision making requires an in-depth analysis of complex cognitive tasks. It involves the exploration of the use of perceptual cues, the development of expert knowledge, and the evolution of expert strategies. This type of exploration is most effective when experts are studied in the context of their complex environments. Cognitive Task Analysis (CTA) methods for eliciting and analyzing the aspects of expertise needed to perform complex tasks have been evolving over the past two decades.
