A Cognitive Map of Human Performance Technology: A Study of Domain Expertise.
Villachica, Steven W.; Lohr, Linda L.; Summers, Laura; Lowell, Nate; Roberts, Stephanie; Javeri, Manisha; Hunt, Erin; Mahoney, Chris; Conn, Cyndie
Most representations of academic disciplines have been created when experts depict or report what they know; however, there are potential problems that can arise when practitioners rely on expert self-report. One way to avoid potential problems associated with expert self-report is to employ cognitive task analysis methods. The Pathfinder Scaling Algorithm is one such method. This software program transforms participants' pair-wise ratings of related concepts into a semantic network-a concept map comprised of nodes (the concepts) and links that depict the relationships among the concepts. Using the Pathfinder Scaling Algorithm (Pathfinder) (Interlink, 1994), the researchers conducted a cognitive task analysis expertise in Human Performance Technology (HPT). The study investigated: the extent to which Pathfinder-derived coherence scores were associated with other measures of HPT expertise; how HPT experts organize their knowledge of the discipline; and how experts organize their HPT knowledge differently than novices. Findings include: a significant correlation between coherence and the number of HPT-related books participants had written; a Pathfinder-derived concept map of HPT; and expected novice/expert differences in Pathfinder similarity and relatedness scores.
