The olfactory perception in matched groups of 26 smokers, 26 nonsmokers, and 15 passive smokers was examined psychophysically with two substances, n-butane and pyridine. Different psychophysical functions were obtained from these groups using the method of magnitude estimation. The smokers and passive smokers perceived all concentrations of n-butane to be weaker than did the nonsmokers. In the case of pyridine, a substance in tobacco smoke to which smokers are more exposed, there is an indication of a perceptual deficit similar to loudness recruitment. There were no appreciable differences between smokers and nonsmokers for high concentrations; the sensitivity was less and the psychophysical functions steeper for smokers than nonsmokers for relatively low concentrations. The results are evaluated in terms of information about the subjects' response criteria, and the authors consider the possibility of sensory deficit versus habituation.
采用正丁烷和吡啶两种物质，对26名吸烟者、26名非吸烟者和15名被动吸烟者的配对组进行嗅觉感知的心理物理学检测。使用量值估计法从这些组中获得了不同的心理物理学函数。吸烟者和被动吸烟者感知到的所有浓度的正丁烷都比非吸烟者弱。对于吡啶这种吸烟者接触较多的烟草烟雾中的物质，有迹象表明存在类似于响度重振的感知缺陷。高浓度时吸烟者和非吸烟者之间没有明显差异；相对低浓度时，吸烟者的敏感性较低，心理物理学函数比非吸烟者更陡峭。根据受试者反应标准的信息对结果进行评估，作者考虑了感觉缺陷与习惯化的可能性。
