Which professional is most likely to study ergonomics?

The professional most likely to study ergonomics is a human factors psychologist. This field focuses on understanding how people interact with products, systems, and environments to improve safety, efficiency, and usability. Human factors psychologists analyze tasks and environments from the perspective of human capabilities and limitations, aiming to design systems that accommodate these factors.

In contrast, clinical psychologists primarily focus on diagnosing and treating mental health disorders through therapeutic techniques. Developmental psychologists study how people change and grow across their lifespan, looking at emotional, cognitive, and social development rather than workplace design or ergonomics. Forensic psychologists apply psychological principles within the legal and criminal justice systems, which does not typically involve studying ergonomics. Therefore, the specialization in human factors is what aligns closely with the principles of ergonomics, making this the correct answer.
