What Is Human Factors Psychology?

Human factors is devoted to understanding how people interact with their environments and the products and objects in those environments. This interdisciplinary area of psychology focuses on a range of different topics related to human-machine or human-computer interaction. Among them are:

  • Human capabilities and errors
  • Product design
  • Workplace safety and ergonomics

The terms “human factors” and “ergonomics” are often used synonymously, with “human factors” being commonly used in the United States and “ergonomics” being the preferred term in Europe.

Human factors applies principles of psychology to the designing of products and creating work environments that boost productivity while minimizing safety issues. This discipline differs a great deal from areas such as clinical psychology or counseling psychology as it does not focus on understanding individuals or psychological issues.

History of Human Factors Psychology

The field of human factors formally began during World War II, when a range of experts worked together to improve the performance and safety of manned systems. Since that time, it has continued to grow and plays a significant role in many other fields, including computing, manufacturing, product design, engineering, military, and government industries.

What a Human Factors Psychologist Does

Human factors psychologists spend much of their time performing research. They use what they know about human behavior, perception, attention, and cognition to create more usable products and work environments.

Human factors psychologists often work to solve real-world problems that impact human performance. For example, they might conduct research on a particular product used in a workplace, such as a screen interface used by workers at an electrical plant.

After researching how employees interact with and utilize the interface, the psychologist can redesign it to make it easier and safer to use, as well as more accurate. They can also help minimize potentially dangerous errors or correct errors that reduce workplace performance.

Other tasks a human factors psychologist might be involved in regularly include:

  • Creating training programs
  • Designing more reliable products
  • Developing ergonomic workstations to reduce employee fatigue and injury
  • Improving productivity and performance

Human factors psychologists help others by developing products that maximize usability. They also strive to improve worker safety and efficiency.


Human factors psychologists may choose to specialize in a particular area. Some of the specialty areas within this field include:
