Cognitive ergonomics focuses on which of the following?

• A. Mental processes such as perception, attention, memory, and decision making
• B. Physical design of equipment only
• C. Work scheduling and staffing
• D. Visual design only

Answer: (A)

Cognitive ergonomics examines how people think and process information as they interact with systems—perception of stimuli, attention to tasks, memory for procedures, and how decisions are made under workload. This focus helps designers create interfaces and workflows that align with how the mind works, reducing errors and improving performance. The best choice captures this by listing mental processes such as perception, attention, memory, and decision making, which are central to cognitive ergonomics.

Options that refer only to physical design describe physical ergonomics; scheduling and staffing pertain to organizational factors; and focusing only on visual design is too narrow and neglects broader cognitive processes like memory and decision making.
