Outside the laboratory setting, performance on inhibition tasks has been found to correlate with problematic impulsive behaviour such as gambling, substance use, aggression and safety-related risk taking (Clark, Cornelius, Kirisci, & Tarter, 2005; Foster, Hillbrand, & Silverstein, 1993; Giancola, Mezzich, & Tarter, 1998; Kirisci, Tarter, Mezzich, & Vanyukov, 2007; Lejuez, Aklin, Zvolensky, & Pedulla, 2003; Nigg, et al., 2006). Similarly a number of mental health disorders that have as part of their pathology an increased level of impulsivity also show impaired performance on inhibition tasks (Alderson, Rapport, & Kofler, 2007; Gruber, Rathgeber, Braeunig, & Gauggel, 2007; King, Colla, Brass, Heuser, & von Cramon, 2007; Mullane, Corkum, Klein, & McLaughlin, 2009; Najt et al., 2005; Vaurio, Simmonds, & Mostofsky, 2009), strengthening the proposition that heightened impulsivity is linked to deficits in inhibition.
