Neurocognitive evidence for deficit in inhibitory control and risky decision making in smokers

Aim and Blackguard: Evaluation and determination of involved neurocognitive mechanism in smoking can be helpful in treatment of this dependence. Methods and Materials: Forty smokers with 40 non smokers participated in study with non probability sampling. In this retrospective study، Go/Nogo and Balloon Analogue Risk Taking Task are used for evaluation of inhibitory control and risky decision making respectively. T-Test was used for analysis. Findings show that smokers and nonsmoker were similar in go stage of go/nogo task. In nogo stage smokers significantly have lower grad from nonsmokers. Smokers have higher risky decision in BART task. High risk taking and low inhibitory control could be considered as predisposing and influencing factors for smoking.
