“…This frontal system assists in goal-directed behaviour and inhibition, and typically reaches full development by the mid to late 20's (Casey, Jones, & Hare, 2008). Disruptions in frontal-limbic systems are associated with excessive risk taking in adolescents and young adults (Dahl, 2008;Gianotti et al, 2009;Mäntylä, Karlsson, & Marklund, 2009;Steinberg & Laurence, 2010), compulsive behaviours and substance abuse in adults (Bechara, Dolan, & Hindes, 2002b;Dom, Sabbe, Hulstijn, & van den Brink, 2005;Koob, 2009;Potenza, Sofuoglu, Carroll, & Rounsaville, 2011;Verdejo-Garcia & Bechara, 2009), reckless driving (Ba, Zhang, Peng, Salvendy, & Crundall, 2016;Brown et al, 2016;Cheng, Ng, & Lee, 2012;Farah, Yechiam, Bekhor, Toledo, & Polus, 2008;Foy et al, 2016;Lev, Hershkovitz, & Yechiam, 2008;O'Brien & Gormley, 2013;Ross et al, 2015;Tabibi, Borzabadi, Stavrinos, & Mashhadi, 2015), and impaired driving (Bouchard, Brown, & Nadeau, 2012;Dedovic et al, 2016;Kasar, Gleichgerrcht, Keskinkilic, Tabo, & Manes, 2010;Ouimet et al, 2007). Overall, evolution across the lifespan in these systems represents a crucial backdrop for understanding individual differences in crash risk.…”
