Final answer:
In Erik Erikson's final stage of psychological development, late adulthood, individuals reflect on their life's accomplishments, leading to a sense of integrity or despair.
Step-by-step explanation:
The maturity stage of ego identity versus despair, as conceptualized by Erik Erikson, occurs in late adulthood from around the mid-60s to the end of life. During this period, individuals look back on their life achievements and experiences. The crucial task here is to assess and make sense of one's life and the meaning of their contributions. An individual might feel a sense of integrity, evident through satisfaction and a lack of regrets, if they perceive their accomplishments as fulfilling. Conversely, if they see their life as unfulfilled and marked by missed opportunities, they may experience despair, characterized by feelings of bitterness and depression. These feelings could stem from unmet career goals, disappointment in personal relationships, or the sacrifices made for success. On the other hand, those who conquer this developmental challenge may discover new opportunities for creativity, and engage in learning new skills and activities as they prepare for the end of life.
