In this thesis a novel use of the Recognition-Primed Decision Model (RPD), and its cognitive task analysis construct, the Critical Decision Method (CDM), is described, as a framework for investigating the underpinnings of expert decision-making in ice hockey. The CDM was employed to examine, in situ, the perceptual-cognitive factors used by elite and intermediate-level ice hockey players in the decision-making process. Data was coded and analyzed using a modified grounded theory approach. The results of study 1 showed that expert hockey players utilize a recognition-centric method of decision-making consistent with the RPD model of expertise. Elements from study 1 shown to be most salient to expert decision-making were used in the design of a training tool that targets the recognition phase of the decision-making process. Finally, a second study was conducted on a major component of the system to measure its effectiveness for transferring perceptual-cognitive learning to the field.
