We tested whether the physiological effects of smoking a cigarette under standard conditions in a laboratory are similar to those seen in a room at home. On two separate test days ten healthy smokers were prepared with a small physiological recorder and were then requested to carry out a protocol requiring them to smoke one of their cigarettes in their usual way either (1) in the laboratory where they had never smoked previously, or (2) at home, alone in a quiet room where they regularly smoke. The experiment which counterbalanced the order of testing showed that in both test situations smoking produced a clear increase in heart rate (HR) and in skin conductance (SC); however, when testing was carried out in the home environment the increase in the HR was significantly less than in the laboratory. No significant differences were found for the baseline HR values in the two environments and there were no significant situational effects in the SC data. It was concluded that under conditions of normal smoking, data on the physiological effects of a cigarette in the laboratory may not be fully generalizable to those seen in the natural smoking situation. Several possible mechanisms of this situationally-specific effect of smoking were discussed.
我们测试了在实验室标准条件下吸烟的生理效应是否与在家中房间里吸烟的生理效应相似。在两个不同的测试日，为十名健康吸烟者配备了一个小型生理记录仪，然后要求他们按照一个方案进行操作，该方案要求他们以自己通常的方式吸一支烟，要么（1）在他们以前从未吸过烟的实验室里，要么（2）在家里，独自在他们经常吸烟的安静房间里。平衡测试顺序的实验表明，在两种测试情况下，吸烟都会使心率（HR）和皮肤电导（SC）明显增加；然而，在家庭环境中进行测试时，心率的增加明显小于在实验室中的增加。在两种环境下，基线心率值没有显著差异，皮肤电导数据也没有显著的情境效应。得出的结论是，在正常吸烟条件下，实验室中关于一支香烟生理效应的数据可能无法完全推广到自然吸烟情况下所观察到的数据。讨论了这种吸烟情境特异性效应的几种可能机制。
