Abstract
In its simplest form, care-giving involves a personal commitment to the needs of another individual, and the entrainment, or close pacing, of two life trajectories. In order to study care-giving from a life-span perspective, five areas of research and thinking must be integrated: (1) life-span development, (2) care-giving across different life stages, (3) the origin and dynamics of care-giving, care-withholding and harm-inducing behaviors, (4) the psychological and the social/economic contexts of care, and (5) the personal versus the relationship dimensions of care-giving.
