It is generally assumed that the mechanical perception of shivering is necessary for the perception of cold discomfort. Shivering of rats in a cool environment was eliminated by curarization. The rats were kept alive by artificial respiration. Heart rate was proportional to rectal temperature in a group of controls. One group of rats was conditioned to increase heart rate to trigger an infrared lamp; another group was conditioned to decrease heart rate to obtain heat. When compared with the results of the control group without infrared heat reward, the results obtained from the two heart-rate-modifying groups show that shivering is not a necessary signal to determine thermoregulatory behavior in rats and, presumably, cold discomfort in man.
一般认为，寒战的机械感知对于冷不适的感知是必要的。在凉爽环境中，大鼠的寒战通过箭毒处理被消除。通过人工呼吸使大鼠存活。在一组对照组中，心率与直肠温度成正比。一组大鼠被训练通过增加心率来触发红外线灯；另一组大鼠被训练通过降低心率来获取热量。与没有红外线热奖励的对照组结果相比，从两个心率调节组获得的结果表明，寒战不是决定大鼠体温调节行为的必要信号，大概也不是决定人类冷不适的必要信号。
