Smoking cue exposure sensitizes smokers to cigarettes (i.e., increases cravings). Research examining the overlap between perception and mental imagery suggests that mentally simulating smoking a cigarette in a manner analogous to actually smoking should lead to habituation or a decrease in a smoker's motivation to smoke. The authors sought to determine whether repetitive mental simulation of smoking can engender habituation thereby reducing smoking cue-induced craving and shifts in mood, latency to smoke, and the hedonic response to smoking. These hypotheses were tested in nontreatment seeking smokers (n = 61; 24 women/37 men) ages 18-55 years old, who were not incentivized to quit. The authors used a 2 (in vivo cue: smoking, neutral) × 2 (imagery: repetitive, limited) within-subjects design. Results revealed that repetitive imagery altered the effect of cue type for negative mood and subjective cigarette reward as evidenced by significant Imagery × Cue interactions. Repetitive imagery after a smoking cue reduced negative mood more than limited imagery (β = -1.19, p = .004). Repetitive imagery also reduced the reward derived from smoking a cigarette more than limited imagery (β = -.41, p < .0001). Only main effects of cue type on craving (β = 3.39, p = .01) and positive mood (β = -1.18, p = .03) were found. Greater imagery strength predicted a longer latency to smoke (β = .76, p = .001). Cognitive strategies that directly engage cue-induced craving through repetitive smoking imagery may reduce smoking cue-induced increases in negative mood and reward from a cigarette lapse potentially preventing smoking relapse.

接触吸烟提示会使吸烟者对香烟敏感(即增加渴望)。研究感知与心理意象之间的重叠表明,以类似于实际吸烟的方式在脑海中模拟吸烟应该会导致习惯化,或者降低吸烟者的吸烟动机。作者试图确定重复的吸烟心理模拟是否会产生习惯化,从而减少吸烟提示引起的渴望以及情绪变化、吸烟潜伏期和对吸烟的享乐反应。这些假设在年龄在18 - 55岁、未寻求治疗且没有戒烟激励措施的吸烟者(n = 61;24名女性/37名男性)中进行了测试。作者采用了2(实际提示:吸烟、中性)×2(意象:重复、有限)的被试内设计。结果显示,重复意象改变了提示类型对负面情绪和主观香烟奖励的影响,意象×提示的显著交互作用证明了这一点。吸烟提示后的重复意象比有限意象更能减少负面情绪(β = -1.19,p = .004)。重复意象也比有限意象更能减少从吸烟中获得的奖励(β = -.41,p < .0001)。仅发现提示类型对渴望(β = 3.39,p = .01)和积极情绪(β = -1.18,p = .03)的主效应。更强的意象强度预示着更长的吸烟潜伏期(β = .76,p = .001)。通过重复吸烟意象直接应对提示引起的渴望的认知策略,可能会减少吸烟提示引起的负面情绪增加以及吸烟失误带来的奖励,从而有可能预防吸烟复发。(PsycINFO数据库记录
