In the psychology literature as late as the 1960’s, a concern could be found for a need to promote psychology as having relevance to the solutions of human problems including those in human-machine systems. The current concern is the perceived shortfall of well-trained professionals in the area of cognitive ergonomics. Today, applied psychology is firmly established in the human-machine systems domain.

Psychology also provides the foundations for the training programs for human operators of those systems.
