Assessment of intertemporal preferences in type-2 diabetes patients and smokers

The experiment assesses the role of cortisol concentration on bloodstream as correlate of the intertemporal choice and temporal discrimination in Type-2 Diabetes Mellitus (T2DM) patients and smokers. The participants were evaluated in a two independent computerized tasks allowed to obtain the tempo...
