An ethological approach to personality development.

attachment that we have jointly developed is that it is an ethological approach to personality development. We have had a long and happy partnership in pursuing this approach. In this article we wish to give a brief historical account of the initially separate but compatible approaches that eventually merged in the partnership, and how our contributions have intertwined in the course of developing an ethologically oriented theory of attachment and a body of research that has both stemmed from the theory and served to extend and elaborate it.
