“…The tendency towards impulsive choice varies between individuals (e.g., Kirby & Marakovic, 1996;Shamosh & Gray, 2008). It is stronger in certain personality types (e.g., Hirsh, et al, 2010) and is associated with certain psychopathologies (e.g., Bobova, et al, 2009). Patients with attention deficit/hyperactivity disorder (ADHD) are more impulsive in this sense (Barkley et al, 2001), as are patients with schizophrenia (Heerey, et al, 2007); cocaine-addicts (Kirby & Petry, 2004), pathological gamblers (Dixon, et al, 2003), smokers (Businelle, et al, 2010) and alcoholics (Mitchell, et al, 2005;Petry, 2001); while the opposite seems to be the case for individuals with higher levels of intelligence (Shamosh & Gray, 2008).…”
