Another area of concern is the use of the automatic BART version. While there are clear advantages of this version (i.e., use of target score, intended number of pumps), it might be that the automatic response mode version removes an aspects of impulsivity from the response procedure. This may be an important element as impulsivity and inhibitory control are typically thought to be a crucial aspect of substance use and risk-taking (Fillmore and Rush 2002). In addition, the automatic response mode procedure eliminates another factor in decision-making that might be important: the dynamics of the ongoing decision while the balloon is being pumped. Each pump produces an observable change in the context (i.e., balloon gets bigger), which impacts the ongoing behavior. Although we argue that the automatic BART is not biased, it might be this bias that captures the ongoing dynamics of decision-making in real time, including the loss aversion and expectancy valence that may change within a single trial during the pumping phase. In summary, the automatic procedure and the standard BART likely measure different cognitive processes during decision-making,
