According to recent theories of addiction, nicotine deprivation may influence biases in the orienting and maintenance of attention on smoking-related cues.
We examined the effect of nicotine deprivation on different aspects of attentional biases for smoking-related cues.
Smokers' eye movements to smoking-related and control pictures were assessed during a visual probe task under deprived and non-deprived conditions.
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.
Results suggest a selective effect of deprivation on the maintenance of attention on smoking-related cues.
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定向和注意力维持中的偏差。
我们研究了尼古丁剥夺对吸烟相关线索注意力偏差不同方面的影响。
在视觉探测任务中，评估吸烟者在尼古丁剥夺和非剥夺条件下对吸烟相关图片和对照图片的眼动情况。
与非剥夺状态相比，处于剥夺状态时，吸烟者对吸烟相关线索的注视时间比对对照线索更长。剥夺状态还增加了对吸烟线索的渴望程度和愉悦感评分。在剥夺和非剥夺两种条件下，相对于非吸烟线索，吸烟者更有可能将目光转向吸烟线索，并且对替换吸烟线索的探测反应更快，但这些注意力偏差指标并未受到剥夺操作的显著影响。
结果表明剥夺对吸烟相关线索的注意力维持有选择性影响。
