Final answer:
Wanda is experiencing Erik Erikson's final stage of psychosocial development known as 'integrity versus despair,' where she reflects on her life with a sense of fulfillment, known as integrity, despite some personal errors.
Step-by-step explanation:
Wanda, at 82 years old, is reflecting on her life, which is indicative of the final stage in Erik Erikson's theory of psychosocial development, integrity versus despair. According to Erikson, during late adulthood, individuals like Wanda look back on their lives and either feel a sense of fulfillment and satisfaction, which Erikson referred to as integrity, or they may experience regret and a sense of failure, known as despair. People who are successful at this stage, like Wanda who feels pride despite acknowledging her errors, have achieved integrity, which allows them to view their past with few regrets and accept the reality of their life course confidently.
