Erik Erikson, who took a special interest in this final stage of life, concluded that the primary psychosocial task of late adulthood (65 and beyond) is to maintain ego integrity
(holding on to one's sense of wholeness), while avoiding despair
(fearing there is too little time to begin a new life course). Those who succeed at this final task also develop wisdom, which includes accepting without major regrets the life that one has lived, as well as the inescapability of death. However, even older adults who achieve a high degree of integrity may feel some despair at this stage as they contemplate their past. No one makes it through life without wondering if another path may have been happier and more productive.
Two major theories explain the psychosocial aspects of aging in older adults. Disengagement theory views aging as a process of mutual withdrawal in which older adults voluntarily slow down by retiring, as expected by society. Proponents of disengagement theory hold that mutual social withdrawal benefits both individuals and society. Activity theory, on the other hand, sees a positive correlation between keeping active and aging well. Proponents of activity theory hold that mutual social withdrawal runs counter to traditional American ideals of activity, energy, and industry. To date, research has not shown either of these models to be superior to the other. In other words, growing old means different things for different people. Individuals who led active lives as young and middle adults will probably remain active as older adults, while those who were less active may become more disengaged as they age.
As older adults approach the end of their life span, they are more apt to conduct a life review. The elderly may reminisce for hours on end, take trips to favorite childhood places, or muse over photo albums and scrapbooks. Throughout the process, they look back to try to find the meaning and purpose that characterized their lives. In their quest to find life's meaning, older adults often have a vital need to share their reminisces with others who care, especially family.
