"Predicting Misdiagnoses in the Transition from Competence to Expertise"

In the quest for expertise, errors are inevitable, as learners test, discard or revise previously learned associations. However, while in some environments the impact of these errors is relatively innocuous, the consequences in other environments, such as medicine, hold much greater significance. Across many domains, successful diagnosis depends on pattern recognition or features-events/object associations in memory that form cues. Although cues are clearly associated with expert performance, their utility amongst novice and competent practitioners is less clear. This project investigates whether the utilisation of cues predicts vulnerability to misdiagnoses during skill acquisition using newly developed measures. Using a psychometric approach, we test the sensitivity of cue utilization in differentiating novice, competent, and expert performance using the Expert Intensive Skills Evaluation 2.0 (EXPERTise 2.0), a generalized, online measure of cue utilization based on cue-based domain specific tasks. It is based on the capacity of the operator to identify, recognize, compare, discriminate and prioritize task-related cues. An independent measure of diagnostic performance was also measured. A physiological measure of cognitive load (right frontal lobe oxygenation levels) was also performed on a subset of the participants. The preliminary results from two expert groups (cardiac sonographers and radiologists) will be presented and the potential outcomes will be discussed.
