Can repetitive mental simulation of smoking engender habituation?

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.
