Final answer:
The objective of ergonomics is to enhance safety and efficiency in the workplace. Human factors psychology, related to ergonomics, addresses issues like the height of the chair to improve workplace design and prevent injury. Ergonomic designs and human factors psychology contribute to workplace productivity, safety, and job satisfaction.
Correct option is B
Step-by-step explanation:
The objective of ergonomics is b) Enhancing safety and efficiency in the workplace. Ergonomics involves the study of people's efficiency in their working environment and it aims to improve workplace design to minimize risk of injury or harm. This science is closely related to human factors psychology, which looks at the interactions between humans, tools, and work systems to optimize human well-being and overall system performance.
For example, a human factors psychologist would be primarily concerned about factors like a) the height of the chair in an office workstation. This is because a chair at the proper height can prevent strain and discomfort, thus contributing to a safer and more productive work environment. Additionally, developments such as desks where employees can stand or cycle aim to enhance physical activity and thus counteract the negative effects of sedentary behaviors.
Overall, the principles of ergonomic design are not only about safety but also relate to productivity and job satisfaction, as seen in bureaucratic systems that aim for increased productivity and efficiency. Human factor professionals may also participate in setting regulations or principles of best design practices which support worker safety and system efficiency.
