Abstract	Given the complexity of most cognitive processes and that of the associated knowledge base, which facilitates effective and efficient use of electronic diagnostic equipment, this paper addresses the important area of understanding how human operators interact with and construct meaningful understanding from the data displayed by such devices. Some work has been done in areas related to graphical and diagrammatical information processing. However, none of these studies considered the interaction of domain and task experts’ performance on similar graphical tasks. The exploratory study presented in this paper intends to identify patterns in cognitive processes used by ultrasound operators, and to provide an explanation for the reason for such patterns in light of the structure and deployment of domain and task-knowledge. The findings illustrate the complex interrelatedness of theoretical and practical knowledge, which constitutes professional knowledge. Professional knowledge becomes more complex when individuals depend on sophisticated tools to assist in their thinking. The study suggests a possibility to think about professional knowledge as a distributed knowledge across task and domain knowledge and knowledge inherent in the tools. Such distributed knowledge in professional practice needs further exploration.Etant donné la complexité de la plupart des processus cognitifs et cela de la base de connaissance associée, qui facilite l’utilisation efficace et efficace de l’équipement diagnostique électronique, adresses de cet article le domaine important de comprendre comment les opérateurs humains agissent l’un sur l’autre avec et construisent la compréhension signicative des données montrées par de tels dispositifs. Un certain travail a été effectué dans les secteurs liés au traitement de l’information graphique et schématique. Cependant, aucune de ces études n’a considéré l’interaction de l’exécution des experts en matière de domaine et de tâche sur les tâches graphiques semblables. L’étude exploratoire présentée en cet article prévoit pour identifier des modèles dans des processus cognitifs employés par des opérateurs d’ultrasons, et pour fournir une explication pour la raison pour de tels modèles à la lumière de la structure et de l’déploiement du domaine et de la connaissance de tâche. Les résultats illustrent l’interrelatedness complèxe de la connaissance théorique et pratique, qui constitue des connaissances professionnelles. Les connaissances professionnelles deviennent plus complexes quand les individus dépendent des outils sophistiqués pour aider à leur pensée. L’étude suggère une possibilité pour penser aux connaissances professionnelles comme connaissance distribuée à travers la connaissance de tâche et de domaine et la connaissance inhérentes dans les outils. Une telle connaissance distribuée dans la pratique professionnelle a besoin davantage d’exploration.
