jan 1, 1939 - World War II
(1939-1945)
Description:
World War II brought renewed interest in ability testing (to accurately place recruits in new technologically advanced military jobs), the introduction of the assessment center, and concern with morale and fatigue in war industry workers.
The emergence of World War II again allowed the field of industrial and organizational psychology to expand due to the growing demands of the military (Spector, 2008; Koppes, 2007; Jex, 2002). World War II not only widened the scope of the field of industrial and organizational psychology, it also opened doors professionally for industrial and organizational psychologists. Before the second World War the American Psychological Association was not concerned with experimental or applied fields within psychology (Spector, 2008; Koppes, 2007). In response to the changes occurring in psychology at the time the APA created Division 14, Industrial and Business Psychology (Spector, 2008; Koppes, 2007; Jex, 2002). This arm of the APA went through a couple of changes and eventually evolved into the Society for Industrial and Organizational Psychology (Spector, 2008; Koppes, 2007; Jex, 2002).
