ABSTRACT
Ladies and Gentlemen; I am very happy to welcome you here at Geneva today and to open the fourth meeting of the Study Group on the Psychobiological Development of the Child, which is to be the last of the present series. As I understand it, the Group intends, during the coming week, to try to synthesize the points of view of the disciplines which it represents and to reach some general agreement as to the interaction of factors involved in the child's development, the way characteristic stages follow one another, and the actual mechanisms involved when one stage succeeds another. It has been agreed that searching for a common language to facilitate understanding between representatives of different specialities is of fundamental importance.
