理由。根据最近的成瘾理论，尼古丁剥夺可能会影响对吸烟相关线索的注意力定向和维持的偏差。目标.我们研究了尼古丁剥夺对吸烟相关线索的注意偏向的不同方面的影响。方法.在剥夺和非剥夺条件下的视觉探测任务中，评估吸烟者对吸烟相关图片和对照图片的眼动。结果当被剥夺时，吸烟者保持他们的目光在吸烟相关的线索比控制，相对于非剥夺。延迟也增加了吸烟线索的渴望和愉快评级。在剥夺和非剥夺条件下，吸烟者更有可能将目光转向吸烟线索，并且相对于非吸烟线索，对取代吸烟线索的探针的反应更快，但这些注意力偏差措施并没有受到剥夺操作的显著影响。结果表明，选择性剥夺对吸烟相关线索的注意力维持的影响。
Rationale. According to recent theories of addiction, nicotine deprivation may influence biases in the orienting and maintenance of attention on smoking-related cues. Objectives. We examined the effect of nicotine deprivation on different aspects of attentional biases for smoking-related cues. Methods. Smokers' eye movements to smoking-related and control pictures were assessed during a visual probe task under deprived and non-deprived conditions. Results. When deprived, smokers maintained their gaze for longer on smoking-related than control cues, relative to when non-deprived. Deprivation also increased craving and pleasantness ratings of smoking cues. Across both deprived and non-deprived conditions, smokers were more likely to shift their gaze towards smoking cues and were faster to respond to probes replacing smoking cues, relative to non-smoking cues, but these attentional bias measures were not significantly affected by the deprivation manipulation.Conclusions. Results suggest a selective effect of deprivation on the maintenance of attention on smoking-related cues.
