What crisis is associated with determining how well one has lived at the end of life?

The correct choice relates to Erik Erikson's psychosocial stages of development, specifically the stage known as integrity vs. despair, which occurs during late adulthood. This stage emphasizes the reflection individuals engage in as they assess their lives. Those who can look back with a sense of fulfillment, recognizing that they have led a meaningful life, achieve a sense of integrity. This leads to feelings of wisdom and peace. Conversely, if individuals reflect and feel regret or disappointment about their past actions or the life they have lived, they may experience despair.

This stage is pivotal as it encapsulates a significant crisis of self-evaluation and acceptance at the end of life, which can deeply influence a person's emotional well-being. Those experiencing integrity find satisfaction in their achievements, whereas those who sense failure might struggle with feelings of bitterness or despair about what could have been.

The other stages listed pertain to different conflicts in earlier stages of development, focusing respectively on establishing relationships, forming one's identity, and finding a balance between productivity and stagnation during middle adulthood. Each stage addresses critical psychosocial challenges, but only the integrity vs. despair stage specifically aligns with the contemplation of one's life at its conclusion.
