Volunteers' body core temperatures were raised to 38.80-39.05 degrees C within a few minutes by immersion in water at 41 degrees C. Tests were then made with the subjects insulated and cooling slowly. Control immersions were made in water at 37 degrees C when core temperatures remained at 36.60-37.40 degrees C. Neither memory registration nor recall of memories registered an hour earlier, nor immediate ability to recall digit spans forward or backward was affected by the increase in core temperature. The increase in temperature did not have any significant effect on accuracy of performance of verbal logic problems or of two-digit subtractions. However, the increase in core temperature was associated with a significant increase in the speed of performance of the tests, by 11 and 10%, respectively. The warm immersions also induced a significant decrease in alertness and an increase in irritability as assessed subjectively by the volunteers; control immersions had no such effects.
通过将志愿者浸入41摄氏度的水中，几分钟内他们的身体核心温度就升高到了38.80 - 39.05摄氏度。然后让受试者进行隔热并缓慢降温的测试。当核心温度保持在36.60 - 37.40摄氏度时，对照组将志愿者浸入37摄氏度的水中。核心温度升高既不影响一小时前记忆的登记或回忆，也不影响即时向前或向后回忆数字广度的能力。温度升高对语言逻辑问题或两位数减法的表现准确性没有任何显著影响。然而，核心温度的升高分别使测试表现速度显著提高了11%和10%。温暖的浸泡也导致志愿者主观评估的警觉性显著降低和易怒性增加；对照组的浸泡没有这些影响。
