Identifying Diagnostic Experts - Measuring the Antecedents to Pattern Recognition

Medical expertise is typically denoted on the basis of experience, but this approach appears to lack validity and reliability. The present study investigated an innovative assessment of diagnostic expertise in medicine. This approach was developed from evidence that expert performance develops following the acquisition of cue associations in memory, which facilitates diagnostic pattern-recognition. Four distinct tasks were developed, for which the judicious extraction and selection of environmental cues may be advantageous. Across the tasks, performance clustered into two levels, reflecting competent and expert performance. These clusters were only weakly correlated with traditional methods of identifying domain experts, such as years of experience. The significance of this outcome is discussed in relation to training, evaluation and
