Industrial-Organizational psychology is an area of psychology that focuses on studying people in their working environment. The role can also involve focusing on workplace dynamics and organizational structures. Through the use of industrial-organizational psychologists, work places can improve the success of their organization.
Industrial-organizational psychology first began in the earlier 20th century when it was found that troops returning from World War I needed therapy to regain morale. It wasn't until after World War II that the field really grew, and as the 20th century progressed the use of a industrial-organizational psychologist in the work place became more common.
Industrial-organizational psychologists typically work either within an organization, or in the academic field. For industrial-organizational psychologists who have gained considerable experience, consulting opportunities are available.
Those who work as an industrial-organizational psychologist can expect to spend a lot of time working with statistics. As developing initiatives on behalf of businesses depends on science-based research, the industrial-organizational psychology relies heavily on working with large numbers.
