There is some evidence to suggest that young women dieters who smoke experience greater cigarette cravings in the presence of food-related related cues. The aim of this experiment was to examine reactivity to both smoking-related and water cues by dieting and non-dieting women smokers in the presence or absence of food cues. Eighteen female undergraduates attended two sessions (food present and food absent). At each session, participants were presented with a cigarette and water cue in a counterbalanced order. Pre- and post-cue measures included the brief version of the Questionnaire for Smoking Urges, heart rate and self-reported mood. All smokers showed enhanced reactivity (increased craving and heart rate) to smoking versus water cues. For dieters there was a larger increase in cigarette craving and heart rate in response to the smoking-related cues in the presence of food compared with the absence of food, whereas for non-dieters there was a smaller increase in cigarette craving and heart rate in response to the smoking-related cues in the presence of food compared with the absence of food. Mood and appetite ratings were not significantly affected by either cue type or session. The results suggest that cue reactivity to smoking-related cues is modulated by the presence of incentive stimuli relevant to the individual.
有一些证据表明，吸烟的年轻女性节食者在食物相关线索存在的情况下，对香烟的渴望更强烈。本实验的目的是检验节食和非节食女性吸烟者在有或没有食物线索的情况下，对吸烟相关线索和水线索的反应性。18 名女大学生参加了两个会议（有食物和无食物）。在每个会议上，参与者以平衡的顺序接受香烟和水线索。在线索出现前后，参与者完成了《吸烟欲望问卷》的简短版本、心率和自我报告的情绪。所有吸烟者对吸烟相关线索的反应性（渴望和心率增加）都增强了，与水线索相比。对于节食者来说，与没有食物相比，在有食物存在的情况下，对吸烟相关线索的烟瘾和心率的增加更大，而对于非节食者来说，与没有食物相比，在有食物存在的情况下，对吸烟相关线索的烟瘾和心率的增加更小。情绪和食欲评分都不受任何线索类型或会议的显著影响。结果表明，对吸烟相关线索的反应性受到与个体相关的激励刺激的存在的调节。
