Piaget classified this final level of his theory as the formal operational stage (Berk, 2010). Subsequent theorists raised the idea of an additional, and new final stage termed postformal thought; appearing in individuals between the ages of 18-25. Postformal thought is an amalgamation of methodical and emotional based reasoning, applied commonly to variable socio-emotional decision making (Berger, 2008; Papalia, Olds & Feldman, 2009; Berk, 2010). Biological adjustments in early adulthood brain function enhance the ability to apply experiential knowledge, and reflective thought; improving problem solving skills. The level of skill applied in these situations depends on the knowledge and experiences an individual has, at that particular time; which also suggest, that those in late adulthood having lived longer, have more experiences and expertise to draw …show more content…
Each level consists of an intellectual aim to be achieved, from a social perspective. The reintegrative stage correlates with late adulthood. Older people within this age group become more susceptible to declines and limitations in brain and cognitive function. The aim at this level is to direct attention to that which holds the greatest value and significance for them (Papalia, Olds, & Feldman, 2009).
