This document outlines the stages of adulthood according to Erikson's psychosocial development theory. It discusses the core struggles and key features of early adulthood (ages 21-34), middle adulthood (ages 35-49), late middle adulthood (ages 50-64), and late adulthood (age 65+). Students are assigned two projects on this topic: 1) teaching their classmates about the different adulthood stages through a presentation, and 2) practicing 5 resilience building characteristics over a week and reflecting on their experiences.
