요약	Selective optimization with compensation (SOC) is a life-span developmental model that explains how people manage the shifting balance of gains and losses across adulthood and old age to maintain functioning and wellbeing. Proposed by Paul Baltes and Margret Baltes in 1990 as a general theory of successful aging, it holds that adaptive development rests on the orchestrated use of three strategies: selection of goals and domains, optimization of the means and resources devoted to those goals, and compensation for losses through alternative means. The model is deliberately metatheoretical, applying from the molecular level of a single skill to the broad organization of a life, and it provided gerontology with a proactive account of agency in aging rather than a story of inevitable decline. Beyond the conceptual model, Baltes and colleagues developed a self-report SOC questionnaire that operationalizes the four facets, turning the theory into a measurable individual-difference construct. Empirically, greater reported use of SOC strategies is associated with higher subjective wellbeing, life satisfaction, and successful-aging outcomes. The framework remains one of the most influential accounts of how individuals adapt to the constraints of later life.	The Rowe-Kahn model operationalizes successful aging as a positive, multidimensional state rather than the mere absence of decline. In their landmark 1997 Gerontologist paper, John Rowe and Robert Kahn argued that gerontology had overemphasized average or 'usual' aging and neglected those who age well, and they proposed a concrete three-part definition. An individual is aging successfully when they simultaneously meet three criteria: low probability of disease and disease-related disability, high cognitive and physical functional capacity, and active engagement with life through productive activity and interpersonal relationships. Crucially, the model treats these as a hierarchy that must be met jointly, so success is defined by the conjunction of all three components rather than excellence on any one. The framework drew on the MacArthur Foundation Research Network's longitudinal studies and reframed aging as something partly within individual and societal control. It became one of the most cited and most debated organizing frameworks in social gerontology, spawning both widespread application and vigorous critique. Its enduring contribution is a clear, testable template for what 'good' aging means and how to classify it.
