Final answer:
In later adulthood, adaptation involves selection, optimization, and compensation as proposed by Baltes and Baltes to address the balance between aging-related losses and gains.
Step-by-step explanation:
In later adulthood, adaptation requires the integration of three processes: selection, optimization, and compensation. The idea of successful personal development and mastery of everyday life challenges relates closely to the concept of selective optimization with compensation theory. Baltes and Baltes (1990) established this theory with a focus on harmonizing the losses associated with aging against the potential gains. Aging is viewed more as a continual process rather than a static outcome, where the goal of compensation is individualized based on personal aims and circumstances.
