A set of psychological factors that can affect the performance of an individual that come from the environment that the individual is situated.

• A. Cognitive ergonomics
• B. Environmental factors
• C. Adjustability
• D. Biomechanics

Answer: (B)

External surroundings can shape how well someone performs by influencing mood, attention, and stress. These psychological effects come from environmental factors like noise, lighting, temperature, and social context. That description fits best, so it’s the right choice. Cognitive ergonomics focuses on designing tools and interfaces to support mental processes, not specifically the environmental influences on performance. Adjustability is about how much a user can tailor a device or setup, a design feature rather than the ambient factors. Biomechanics deals with body movement and physical forces, not the psychological effects arising from the environment.
