Abstract : This project addressed the role of knowledge structure in skilled cognitive task performance. In particular, efforts focused on four areas: identification of attributes affecting the development of knowledge structures, derivation of theoretical dimensions for the knowledge structure construct, mapping the impact of knowledge structure on task performance and derivation of automated knowledge structure measures. This project has provided information useful for the selection and training of personnel, suggesting a focus on selecting and training individuals to develop the appropriate knowledge structure. Both the type of knowledge structures and examples of effective training methods are provided. Key unanswered questions include (1) the development of a comprehensive matching algorithm between particular task features and the type of knowledge structure which is best suited for these task attributes, and (2) identification of individual difference characteristics which influence the type of knowledge structure developed. Knowledge structure, Skilled task, Performance, Expertise.
