Hypothesis

Smokers will show reduced response inhibition compared to non-smoking controls, particularly during smoking cue exposure.

Conclusion

Smokers have difficulties with response inhibition, which may be an important factor in smoking behaviors and cessation programs.

Supporting Evidence

  • Smokers had reduced NoGo N2 amplitudes compared to non-smokers.
  • Behavioral accuracy was lower in smokers on NoGo trials.
  • Smokers reported increased craving after task performance.

Takeaway

Smokers find it harder to stop themselves from doing things when they see pictures of smoking, which can make it tough for them to quit.

Methodology

Participants performed a smoking Go/NoGo task while their brain activity was recorded using event-related potentials.

Limitations

The study design does not allow for conclusions about causality between reduced inhibitory control and smoking.

Participant Demographics

19 smokers (mean age 21.36 years, 14 male) and 20 non-smoking controls (mean age 21.55 years, 14 male).
