Page "Industrial and organizational psychology" Paragraph 2

In classic overviews of the field, Guion ( 1965 ) defines I – O psychology as " the scientific study of the relationship between man and the world of work: ... in the process of making a living " ( p. 817 ).

Blum & Naylor ( 1968 ) define it as " simply the application or extension of psychological facts and principles to the problems concerning human beings operating within the context of business and industry " ( p. 4 ).

As evident by its name, I – O psychology has historically subsumed two broad areas of study that investigate the nature of the person ( individual-differences psychology ) and the nature of the situation or context ( social psychology ), although this distinction is artificial, as many topics in I-O psychology are informed by both of these general areas.

Sometimes, I – O psychology is considered a sister field or branch of organizational studies, organizational science, organizational behavior, human resources, and / or management, but there is no universally accepted classification system for these related fields.
