Step-by-step explanation:
Dr. Shi, who runs a research lab that studied pilots' response to symbols on a display, is most likely a human factors psychologist. Human factors psychology focuses on how individuals interact with the tools and interfaces in their work environment to optimize productivity, safety, and health. This specialization within industrial and organizational psychology addresses both physical and cognitive interactions, such as the fit of workplace equipment or the usability of complex information displays. Additionally, it is concerned with enhancing workplace safety by studying and improving interactions between technology systems and their human operators, which relates closely to Dr. Shi's research with pilots.
