Abstract : Two crews from the Air Defense Command were charged with the responsibility of defending the United States against hostile attack and then exposed to high stress situations in a simulated manual Air Defense Direction Center. Their responses were analyzed to determine what, if any, characteristic response patterns emerged. The following were suggested by the analysis of the data: (1) When reality is too complex to deal with first-hand, a man-machine system will construct a model of reality. This model is continuously modified by the system (to take into account changes in reality and changes in proficiency) but the modifications always reflect the charged responsibility. (2) The model of reality is then evaluated to determine the best of several possible responses. Responses are selected in terms of which most effectively meets the charged responsibility. (3) A system, apparently unconsciously, operates at a level of effort that remains relatively constant for the job at hand and will exceed this level rarely and for short intervals only. (4) A system apparently orders reality on a subjective list ranging from 'immediate response is mandatory' to 'no response is necessary' and then responds reading from the top of the list to the point of the system level of effort. (5) The major effect of stressing the system is to provoke a more careful culling of the list rather than increase the level of effort. (Author)
