“…In general, personality-based impulsivity traits increase with the onset of puberty through the early 20s and then level off in the transition into middle-adulthood Romer & Hennessy, 2007;Steinberg et al, 2008), although this pattern is not as robust for sensation seeking (Collado et al, 2014;Harden & Tucker-Drob, 2011;Pedersen et al, 2012). For behavioral measures, delayed reward discounting decreases from adolescence into adulthood (Green et al, 1994;Olson et al, 2007;Prencipe et al, 2011) and response inhibition performance improves from adolescence into adulthood (Jaeger, 2013;López-Caneda et al, 2014). It has been suggested that the increase in impulsivity during adolescence results from the gap between the early development in the affective processing system (including areas of the mesolimbic dopamine circuit) and later development of the cognitive control system (including the lateral prefrontal cortex and parts of the anterior cingulate cortex) (Ernst and Fudge, 2009;Somerville et al, 2010;Stautz and Cooper, 2013;Steinberg, 2008).…”
