“…Adolescence is strongly associated with a heightened instability in these traits, potentially influenced by neurodevelopmental changes in this developmental stage (Crone & Dahl, 2012; Ernst & Fudge, 2009; Steinberg, 2008; Steinberg et al, 2008). Sensation seeking increases in early adolescence, with a peak in middle adolescence, and decreases closer to young adulthood (Littlefield et al, 2016; Romer & Hennessy, 2007; Steinberg et al, 2008); however, some studies have found an increase in sensation seeking moving toward young adulthood (Collado et al, 2014; Harden & Tucker-Drob, 2011; Pedersen et al, 2012). Negative urgency and positive urgency increase during early adolescence (i.e., 11–13 years) and decline across later adolescence (Littlefield et al, 2016).…”
