The final volume of the series covering ideas and issues associated with the life-span perspective. Topics covered in the book include: constancy and change in human development; and individual differences in life paths.

"This 12th volume in the series is an impressive collection of some of the very best empirical and theoretical work in the area....this poignant ending to the series is marked by an excellent collection of works, each of which addresses life span development from a different vantage point. The editor's planfulness about the volume is reflected in the thoughtful complementarity and diversity of perspectives represented in the book."
