Reduced inhibitory control is a general characteristic of smokers and becomes increasingly pronounced in smoking-related contexts. However, research has rarely considered differences in the effects of various smoking-related cues. To fill this research gap, this study compared the effects of smoking object-related and smoking social-related cues on inhibitory control in smokers.
We used a visual Go/NoGo paradigm with three types of long-lasting backgrounds (neutral, smoking object, and smoking social background) to record the error rates, reaction times, and amplitudes of the N2 and P3 event-related potentials (ERPs) by 25 smokers and 25 non-smokers.
(1) Smokers displayed smaller NoGo-N2 amplitudes than controls under the neutral background; (2) smokers displayed smaller NoGo-N2 amplitudes under the smoking social background and smoking object background than they did under the neutral background; (3) relative to neutral and smoking object backgrounds, smokers displayed higher commission error rates, shorter reaction times, and larger NoGo-P3 amplitudes under smoking social background.
Smoking-related stimuli impair inhibitory control in smokers, especially when these stimuli are socially related.
抑制控制能力下降是吸烟者的一个普遍特征，并且在与吸烟相关的情境中会变得愈发明显。然而，研究很少考虑各种与吸烟相关线索的影响差异。为填补这一研究空白，本研究比较了与吸烟对象相关和与吸烟社交相关线索对吸烟者抑制控制的影响。
我们采用视觉Go/NoGo范式，设置三种类型的长效背景（中性、吸烟对象和吸烟社交背景），记录25名吸烟者和25名非吸烟者的错误率、反应时间以及N2和P3事件相关电位（ERP）的波幅。
（1）在中性背景下，吸烟者的NoGo-N2波幅比对照组小；（2）吸烟者在吸烟社交背景和吸烟对象背景下的NoGo-N2波幅比在中性背景下小；（3）相对于中性和吸烟对象背景，吸烟者在吸烟社交背景下的错误率更高、反应时间更短、NoGo-P3波幅更大。
与吸烟相关的刺激会损害吸烟者的抑制控制能力，尤其是当这些刺激与社交相关时。
