Final answer:
Older adults who reflect on their lives with satisfaction demonstrate a sense of integrity, aligning with Erikson's stage of 'integrity versus despair' in his psychosocial development theory.
Step-by-step explanation:
Older adults who feel satisfied when reflecting on their lives demonstrate what Erik Erikson called a sense of integrity. In Erik Erikson's framework of psychosocial development, the stage relevant to late adulthood is characterized by the challenge of integrity versus despair.
Older individuals look back on their life experiences and accomplishments, and depending on whether they feel a sense of fulfillment or regret, they may either develop a strong sense of integrity or face feelings of despair. Achieving integrity means that the individual has managed to see their life as meaningful and can accept both successes and failures with acceptance. On the contrary, those who struggle to achieve integrity may experience regret, feeling that their lives have not been lived to their full potential, which can lead to despair.
