A comparison of one-, two-, and three-man units under various conditions of work load

Abstract

How does adding workers to a team effect output? 9 college students were used to simulate a radar control situation involving an increasing load of approaching aircraft. Performance decreased with added load, however, adding helpers upgraded performance only slightly. "The results of this experiment indicate that simple crew augmentation does not necessarily improve the capacity of a complex man-machine system." (13 ref.) From Psyc Abstracts 36:04:4LF95K.
