The literature on investigations into effects of thermal stress of psychological performance is reviewed in order to hypothesize ways in which functions of a decision-making process may be affected by exposure of a decision maker to hot and cold environmental conditions. A theoretical model is described relating psycho-physiological strain, associated with exposure to environmental thermal stress, to efficiency of performance of psychological tasks, categorized in terms of demands made on the human operator. From the evidence available, it appears that three aspects of decision making may be vulnerable to adverse effects of thermal stress. The initiation of the process of decision making may occur less reliably when cold or heat stress leads to signals, which may be serving as decision-making process prompts, being missed. Cognitive operations relating to information processing and evaluative procedures may be subject to decrements in efficiency when conducted in thermally stressful conditions. Thirdly, actions intending to implement decisions taken may be less effectively performed in thermally extreme environments.
本文回顾了关于热应激对心理表现影响的研究文献，以便推测决策者暴露于炎热和寒冷环境条件下时，决策过程的功能可能受到影响的方式。文中描述了一个理论模型，该模型将与暴露于环境热应激相关的心理生理应变与心理任务的执行效率联系起来，心理任务根据对人类操作员的要求进行分类。从现有证据来看，决策的三个方面可能容易受到热应激的不利影响。当寒冷或热应激导致可能作为决策过程提示的信号被错过时，决策过程的启动可能不太可靠。在热应激条件下进行与信息处理和评估程序相关的认知操作时，效率可能会下降。第三，在极端热环境中，旨在执行所做决策的行动可能执行得不太有效。
