Abstract
Several advantages and disadvantages of a life-span concept are reviewed. The particular life-span concept of attachment is examined with respect to theory and methodology. Suggestions are offered which would: (a) redefine the concept of attachment focusing on the ontogenetic development of an individual throughout their lifetime, and (b) foster the use of a more sensitive methodology. This paper also introduces the symposium by providing brief prefacing comments on each of the papers to follow.
