Answer:
Psychology, very generally, is the scientific study of the human mind. Industrial psychology is one of the first attempts to apply psychology to the workplace and has its roots in the pioneering work of Frederick Taylor. It has since expanded to include topics like efficiency, productivity, training, and assessment. It should not be confused with organizational psychology, where there is more focus on motivation, leadership, teams, culture and organizational development. They are often combined and referred to as I-O psychology.
