“…Two contrasting hypotheses were formulated for the developmental trajectories of goal investment and momentum. On the one hand, because people set their goals in accordance with developmental tasks (Heckhausen et al, 2010;Nurmi, 2004;Salmela-Aro, 2010) and individuals face many developmental tasks during this age period (Caspi, 2002; see also Seiffge-Krenke, Kiuru, & Nurmi, 2010), it can be hypothesized that the overall investment in personal goals, as well as goal momentum remain high throughout young adulthood. On the other hand, it can be assumed that setbacks and disappointments that characterize the lives of young people (EGRIS, 2001;Messersmith & Schulenberg, 2010) might be associated with temporal or even stable decline in goal investment and momentum.…”
