Workplace Psychology: Defining I-O, Its Fields, and Key Figures

Industrial-Organizational Psychology Defined

Blum and Naylor (1968) define Industrial-Organizational (I-O) Psychology as:

"The application or extension of psychological facts and principles to problems concerning human beings who work within the context of business and industry."

Key Contributions and Benefits of I-O Psychology

I-O Psychology principles can be applied to:

• Hire better employees
• Reduce absenteeism
• Improve communication
• Increase job satisfaction
• And many other workplace challenges.

Core Areas of Industrial-Organizational Psychology

I-O Psychology encompasses several subspecialties, typically categorized into six general areas:

1. Selection and Placement

   This area focuses on the selection, placement, and promotion of employees. It involves matching individuals to jobs based on their interests, abilities, and skills to ensure optimal fit and performance.

2. Training and Development

   I-O psychologists identify employee skills that need improvement to enhance job performance. This includes designing and implementing training programs and evaluating their effectiveness to ensure successful skill development.

3. Performance Evaluation

   This involves evaluating employee performance against established criteria and standards. The goal is to determine how well employees are performing their work and to assess the overall usefulness and value of their job performance to the organization.

4. Organizational Development

   Organizational Development is the process of analyzing an organization's structure to maximize the satisfaction and effectiveness of individuals, work groups, and customers. It facilitates organizational growth and adaptation.

5. Quality of Work Life

   This area focuses on ensuring a healthy and productive workforce. It often involves redesigning jobs to provide more meaningful content and create more satisfying experiences for employees.

6. Ergonomics

   Ergonomics is a multidisciplinary field within I-O Psychology dedicated to designing tools, equipment, and machines that are compatible with human capabilities. It utilizes knowledge from physiology, industrial medicine, and work perception to create systems that can be operated efficiently and safely by humans.

Founding Figures of Industrial-Organizational Psychology

Three individuals are widely recognized as the founding fathers of I-O Psychology:

Walter Dill Scott (1869-1955)

A prominent psychologist, Walter Dill Scott authored influential books such as The Theory of Advertising (1903) and The Psychology of Advertising (1908), which explored suggestion and argument as methods to influence people. He also wrote on increasing human efficiency through tactics like imitation, competition, loyalty, and concentration. During the First World War, Scott was instrumental in applying personnel procedures within the military, significantly increasing public awareness and credibility of Industrial Psychology.

Frederick W. Taylor (1856-1915)

An engineer who rose from a laborer to a plant manager, Frederick W. Taylor is known for his principles of scientific management. His core principles include:

• Science over Rule of Thumb: Replacing traditional, inefficient methods with scientifically determined best practices.
• Scientific Selection and Training: Systematically selecting and training employees for specific tasks.
• Cooperation over Individualism: Fostering collaboration between management and workers.
• Division of Tasks: Clearly dividing responsibilities between managers (planning) and employees (executing).

Hugo Münsterberg (1863-1916)

A German psychologist, Hugo Münsterberg applied experimental methods to various problems, including perception and attention. He was deeply interested in applying traditional psychological methods to practical industrial problems. His influential book, Psychology and Industrial Efficiency (1913), covered topics such as worker selection, the design of work situations, and sales psychology. One of his most noted studies involved determining the psychological characteristics of safe tram drivers.

These foundational contributions laid the groundwork for understanding individual behavior within the workplace, a cornerstone of modern I-O Psychology.
