Generativity of Expertise

拟议中的工作扩展了对传统专业知识的研究 通过创造性地使用统计数据进行描述性或规范性分析 定义和测量信息和感知模式的方法 的专家。 目前，对专家进行这种分析的方法 并不存在 拟议的研究扩展了以前的实验室工作 复杂的现场环境（医疗决策）。 但 方法和结果应该与任何需要 对大量专业知识的理解和应用 知识 拟议的研究调查专家医师的能力 来解决新的诊断问题。 使用生成方法， 关于医生使用的知识， 来执行复杂的诊断任务。 对这些假设进行了检验 使用医生知识的描述， 分析患者记录。 这些案件的表现将是 检查生成性的证据，包括流畅性，策略性 解决问题，并使用一般知识。 研究延伸 以往对专业判断生成性的研究 并明确地研究了感知和 解决问题的战略方面。

The proposed work expands research on expertise beyond traditional descriptive or normative analyses by creatively using statistical methods to define and measure informational and perceptual patterns of experts. Presently, methods to conduct such analyses of experts do not exist. The proposed studies extend previous laboratory work to a complex field setting (medical decision making). However, the methods and results should be relevant for any domain that requires the understanding and application of large amounts of specialized knowledge. The proposed research investigates the ability of expert physicians to solve novel diagnostic problems. Using a generative approach, hypotheses are developed regarding the knowledge used by physicians to perform a complex diagnosis task. These hypotheses are tested using descriptions of physicians' knowledge constructed from analyses of patient records. Performance on these cases will be examined for evidence of generativity including fluency, strategic problem solving, and use of general heuristics. The study extends previous investigations of generativity to professional judgment and explicitly examines the relationship between perceptual and strategic aspects of problem solving.
