Measuring the structure of expertise

This report reviews work on defining and measuring conceptual structures of expert and novice fighter pilots. Individuals with widely varying expertise were tested. Cognitive structures were derived using multidimensional scaling (MDS) and link-weighted networks (Pathfinder). Experience differences among pilots were reflected in the conceptual structures. Detailed analyses of individual differences point to factors that distinguish experts and novices. Analysis of individual concepts identified areas of agreement and disagreement in the knowledge structures of experts and novices. Applications in selection, training and knowledge engineering are discussed.

      For example, increased knowledge of vaccines may improve vaccine perception and uptake [15–17]. Due to socio-cultural differences, educational or training pedigree, expert and consumer representations of knowledge may differ [18]. This has implications in the health domain, and therefore, needs to be examined if health care-related artifacts are to be targeted for particular audiences [19].
