This document discusses cognitive development in emerging adulthood, including postformal thought and higher-level reasoning abilities that develop beyond adolescence. It proposes that adulthood brings greater practical thinking, flexibility, and ability to integrate contradictory ideas. While some question if this is a distinct stage, research finds cognitive changes through the adult lifespan. Adults can better combine logic and emotion to solve complex problems. Culture also influences cognitive processes like dialectical thought. Higher education may support cognitive growth through exposure to diverse views and complex problem-solving.
