Smoking is associated with significant negative health consequences. It has been suggested that deficient inhibitory control may be implicated in (nicotine) addiction, but its exact role has not yet been elucidated. In the current study, our aim was to investigate the role of inhibitory control in relation to nicotine addiction in contexts that differ in terms of reward.
Participants filled out questionnaires and performed a go/no-go task with three conditions. In one condition, the stimuli were neutral color squares, and in the reward conditions, these were smoking-related pictures and money-related pictures, respectively. In total, 43 non-abstinent individuals that smoke and 35 individuals that do not smoke were included in the sample.
The main results showed that individuals that smoke, relative to individuals that do not smoke, had reduced inhibitory control in both reward contexts, relative to a neutral context. The reductions in inhibitory control were mirrored by speeded responses.
Individuals that smoke seem to present with reduced inhibitory control, which is most pronounced in contexts of reward. Consistent with incentive sensitization theory, the reduced inhibitory control may be (at least partly) due to the heightened approach bias to reward-related stimuli as indicated by the speeded responses.
吸烟会对健康造成严重的负面影响。有人认为，抑制控制不足可能与（尼古丁）成瘾有关，但其确切作用尚未阐明。在本研究中，我们的目的是在奖励不同的情境下，研究抑制控制与尼古丁成瘾之间的关系。
参与者填写问卷，并在三种条件下执行一项停止信号任务。在一种条件下，刺激物是中性颜色方块，在奖励条件下，分别是与吸烟相关的图片和与金钱相关的图片。样本中总共包括43名非戒烟的吸烟者和35名不吸烟者。
主要结果表明，与不吸烟者相比，吸烟者在两种奖励情境下相对于中性情境的抑制控制能力均有所下降。抑制控制的下降表现为反应速度加快。
吸烟者似乎表现出抑制控制能力下降，这在奖励情境中最为明显。与动机敏感化理论一致，抑制控制能力下降可能（至少部分）是由于反应速度加快所表明的对奖励相关刺激的趋近偏向增强。
