Final answer:
The Knowledge bases on an HR Case are determined by the Contextual Search configuration, with the human factors psychologist's research on this topic falling under the area of human-computer interaction (HCI), focusing on optimizing the user experience.
Step-by-step explanation:
The Knowledge bases searched for the Knowledge results section on an HR Case in ServiceNow or similar platforms are determined by the Contextual Search configuration. The system uses this configuration to understand the context of the HR Case and retrieve the most relevant knowledge articles to address the user's needs. This configuration can involve various criteria such as keywords, related concepts, user roles, and more to filter and prioritize knowledge base results that are most useful for the HR Case in question.
When a human factors psychologist studies how a worker interacts with a search engine, they are conducting research in the area of human-computer interaction (HCI). In the specific case of a human factors psychologist focusing on the use of a search engine, their research would be concerned with optimizing the user experience by studying and improving the interface design, search algorithms, and user behavior.
