A comparison of the effects of training and secondary tasks on tracking behavior.

In attempting to estimate what kind of a mechanism would best replace the human operator in a man-machine system, 6 sailors operated radar sets while their performance was studied by electronic computers (analog). The effects of training and secondary scores were studied in terms of errors. The type of mechanism it would take to replace the man depended upon the level of training the man had received.
