Volunteers' body core temperatures were lowered by immersion in water at 15 degrees C. Aspects of cognitive function were subsequently tested after rewarming had been started in water at 41 degrees C when their skin was warm and they felt comfortable but their body core temperature remained low. Memory registration was found to be impaired progressively when core temperature fell from about 36.7 degrees C; at core temperatures of 34-35 degrees C the impairment caused loss of approximately 70% of data that could normally be retained. However, recall of previously learned data was not impaired at these core temperatures. On a two-digit calculation test, speed of performance was impaired by about 50% at a core temperature of 34-35 degrees C, but provided enough time was available, accuracy of performance was not reduced.
志愿者的体核温度通过浸泡在15摄氏度的水中而降低。随后，当他们的皮肤变暖且感觉舒适但体核温度仍然较低时，在41摄氏度的水中开始复温后对认知功能的各个方面进行了测试。当核心温度从约36.7摄氏度下降时，发现记忆登记逐渐受损；在核心温度为34 - 35摄氏度时，这种损害导致约70%的正常可保留数据丢失。然而，在这些核心温度下，对先前所学数据的回忆并未受损。在一项两位数计算测试中，在核心温度为34 - 35摄氏度时，表现速度受损约50%，但如果有足够的时间，表现准确性并未降低。
