The elderly stage of life is recognized as a period combining both loss and acquisition. Although the acquisition of qualities such as wisdom and insight are considered positive, a corresponding sense of loss cannot be evaded. The psychosocial task based on E. H. Erikson's epigenetic schema, however, does not resist the idea of a negative experience. Accordingly, it is useful for an understanding of this stage of life. I reviewed and considered the psychosocial tasks present in the elderly stage of life and focused on three specific research areas: the measuring method of psychosocial problems (investigative approach), the factor relation to psychosocial problems (related factor), and the feature of psychosocial problems (feature of the eighth stage). Two problems and considerations: (1) the necessity of creating a balance between positive and negative constructs, as Erikson emphasized, and (2) the necessity of introducing psychosocial tasks to the elderly by means of experimental study. Further studies are needed to assess how psychosocial tasks are invoked when providing clinical psychological support for elderly.
