Final answer:
A human factors psychologist would be concerned about the height of the chair in an office workstation.
Step-by-step explanation:
A human factors psychologist would be concerned about the height of the chair in an office workstation. This is because the height of the chair is directly related to ergonomics and can impact the comfort and posture of the individual using the workstation.
Proper chair height ensures that the user's feet are flat on the ground and their knees are at a 90-degree angle. This helps to prevent musculoskeletal disorders and promote good posture.
Therefore, in order to create an optimal and safe workspace, a human factors psychologist would pay close attention to the height of the chair.
