PSY7240 examines the full arc of adult psychological development, from the emerging adulthood of late adolescence through the challenges and opportunities of old age. Drawing on lifespan developmental theories — Erik Erikson's psychosocial stages, Daniel Levinson's seasons of adult life, selective optimization with compensation theory, and contemporary empirical research — students evaluate what changes and what remains stable across adulthood and apply this understanding to psychological service delivery in workplaces, family systems, clinical settings, and social relationships.
Lifespan adult development and psychological well-being
Core topics
- Theories of adult development: The major theoretical frameworks — Erikson's stages of intimacy vs. isolation, generativity vs. stagnation, and ego integrity vs. despair; Levinson's seasons of adult life; continuity theory; socioemotional selectivity theory (Carstensen); and the selective optimization with compensation model (Baltes) — and the empirical research that supports, refines, or challenges each
- Cognitive changes across adulthood: The trajectory of fluid and crystallized intelligence across adulthood, age-related changes in processing speed and working memory, wisdom and expertise as forms of cognitive growth in later life, and the distinction between normative cognitive aging and pathological decline
- Adult life transitions: The psychological challenges and developmental tasks of major adult transitions — establishing intimate relationships, career entry and advancement, parenthood, midlife reassessment, retirement, bereavement, and adapting to physical aging — and how individuals vary in their responses to these transitions
- Adult well-being, resilience, and longevity: The psychological, social, and behavioral factors associated with successful aging and longevity — the roles of social connectedness, purpose, physical health behaviors, and coping strategies — and what psychological interventions can support psychological well-being across adulthood
- Applying service delivery models to adult populations: How psychological services in workplaces (employee assistance programs, organizational consulting), family contexts (couples therapy, family systems approaches), and clinical settings adapt to the specific developmental needs, strengths, and challenges of adults at different life stages

Frequently asked questions
Child and adolescent development has historically received more research attention, partly because changes are dramatic and partly because school settings create natural research populations. Adult development is more variable — adults follow more individualized trajectories shaped by accumulated life experiences, choices, and cultural contexts — and is often better characterized by selective change rather than universal stages. Research increasingly emphasizes that development is not complete at the end of adolescence: neuroplasticity continues into midlife, emotional regulation typically improves with age, wisdom and expertise accumulate over decades of practice, and adults maintain capacity for growth and change throughout life. For psychologists, this matters because most of their adult clients are navigating life transitions, identity revisions, relationship challenges, and coping with stress — all of which require developmental context. PSY7240 provides that context, developing the lifespan framework that helps clinicians, organizational psychologists, and counselors understand their adult clients' experiences within the full arc of human development.
