成人期の社会情緒的発達に関するエリクソンの理論

Erikson's psychosocial development theory highlights key challenges in adulthood: intimacy versus isolation, generativity versus stagnation, and integrity versus despair.

Intimacy versus isolation occurs in early adulthood, from the 20s to the early 40s. The challenge is to form deep, meaningful, and intimate relationships.

Success fosters emotional intimacy and strong connections, while failure leads to loneliness and isolation.

Middle adulthood, from the 40s to mid-60s, centers on generativity versus stagnation. Generativity involves contributing to future generations through parenting, mentoring, or meaningful work.

Those who succeed feel a sense of purpose and legacy, while stagnation brings feelings of disconnection and lack of fulfillment.

In late adulthood, from the mid-60s onward, the focus shifts to integrity versus despair. Individuals evaluate their lives, seeking meaning in their experiences and achievements.

Integrity results from accepting one's life as valuable and complete, bringing peace and satisfaction.

Despair occurs when individuals regret their past or feel a sense of purposelessness, often linked to fear of death.
