The sociology of the life course and life span psychology: integrated paradigm or complementing pathways?

The psychology of the life span and the sociology of the life course share the same object of scientific inquiry - the lives of women and men from birth to death. Both are part of an interdisciplinary field focused on individual development and life course patterns which also includes social demography and human capital economics. However, a closer look shows that life span psychology and life course sociology now to stand further apart than in the seventies. In this paper we reassess how this divergence can be understood in terms of necessary and legitimate strengths of both approaches, as well as avoidable weaknesses which could be overcome in the future by more re-combination and integration.
