Abstract : Subjects in troop carriers were required to respond rapidly to obscure signals occurring randomly under conditions of heat; heat, noise and vibration; noise and vibration and under a control condition. Noise and vibration produced a significant increase in response time. Heat in combination with noise and vibration produced an additional but transitory decrement, but heat alone did not produce a significant change. No general temporal effect was observed. (Author)
