The present paper describes a re-analysis of the relationship between threshold for unimpaired mental performance and heat stress. Review of the data presented by Wing (1965a), and of more recent research, suggests that heat induced mental performance decrement is a function of imminent thermophysiological collapse and occurs at a much higher level of heat stress than Wing has proposed.
