Chapter 18: Emerging Adulthood: Cognitive Development

The chapter introduces postformal thought as a cognitive stage that extends beyond Piagetian formal operations, characterized by the ability to think flexibly, integrate practical concerns with abstract reasoning, and synthesize emotional and logical dimensions of problem-solving. Dialectical thinking represents the pinnacle of this cognitive development, enabling emerging adults to hold contradictory ideas simultaneously, recognize the thesis and antithesis within complex situations, and generate synthesis that acknowledges reality's dynamic nature. The chapter also addresses how cognitive limitations like stereotype threat can undermine performance but demonstrates how postformal thinkers can manage these pressures through emotional awareness combined with strategic thinking. Moral development advances substantially during emerging adulthood through exposure to diverse perspectives and ethical frameworks, as measured by instruments like Rest's Defining Issues Test, which reveals that higher education correlates with more sophisticated moral reasoning. The chapter integrates faith development models, particularly Fowler's framework, which progresses toward universal compassion and justice-oriented principles in adulthood, alongside Haidt's moral foundations theory highlighting how care, freedom, fairness, purity, and authority principles vary across cultural contexts. The second major focus examines higher education's transformative role, exploring how massification of college access creates broad societal benefits including improved health outcomes, economic mobility, and enhanced cognitive capabilities. The chapter emphasizes that colleges function as catalysts for intellectual growth when they promote diversity, integrate technology thoughtfully through active learning approaches, and create psychologically supportive environments. However, the chapter candidly addresses real obstacles emerging adults face, including financial strain, mental health struggles, and academic pressures, while identifying institutional practices that foster both cognitive and moral development despite these challenges.
