Aim and Back ground: Impulsivity and risky decision making is a core element of plenty of individual and social deficits. On the other hand, history of attention deficit disorder and hyperactivity has been reported in many people with these problem particularly addiction. Decision making requires basic cognition function such as inhibition, working memory and attention. The aim of the current study was to explore the relationship between risky decision making with attention functions, work memory and Inhibitory control. Methods and Materials: In present cross sectional study, 215 students of Shahid Beheshti University were evaluated with neuropsychological tests such as N- back, Stroop test, Wisconsin Card Sorting Test, Continuous Performance Test and Go/NoGo Test. Pearson correlation was used for analysis. Finding: Findings not found any significant correlation between sustain, selective and shifting attention and risky decision making (P> 0.05). Significant correlation found between inhibitory control and risky decision making (P< 0.01). Conclusions: Different anatomic origin of decision making (ventromedial prefrontal) and executive function (dorsolateral prefrontal) could be considered as a resign of their independence. Inhibitory control is a good predictor of risky decision making and interventional study may be propose training of inhibitory control for reducing risky decision making.
