Gisela Labouvie-Vief (1980) extended Jean Piaget’s cognitive-development theory into adulthood by offering a theory of pragmatic thought and cognitive-emotional complexity that sees adult development as an active process of constructing successively more adaptive levels of activity. As a neo-Piagetian theory, Goldhaber (2000) classified Labouvie-Vief's theory of programmatic thought and cognitive-emotional under an organismic lens. Because Labouvie-Vief demonstrated how contextual factors can influence cognitive development, Merriam (2007) classified the theory as contextualist. Seemingly then, Labouvie-Vief's theory belongs under a contextualist-organismic lens.
